The Flair Airlines Fleet In 2021

From Simple Flying – link to source story

by Chris Loh | July 10, 2021

With Flair’s rapid expansion over the past year, the airline will need to ensure it has sufficient aircraft to fulfill its scheduling commitments. When the airline began 2021, it had three- yes, just three- Boeing 737-800 aircraft. Its fleet has now grown to have eight 737s, with more on the way. Let’s take a look at the Flair Airlines fleet in 2021.

Starting with just three 737-800s

Flair Airlines began the year with just three Boeing 737-800s. These jets were acquired on the second-hand market, flying with Flair since mid-2019. Collectively, these have an average age of just under 11 years. Registered C-FFLA, C-FFLC, and C-FFLJ, these older jets have flown with airlines such as Air China, Germany’s Air Berlin, and Thailand’s Siam Air. Simple Flying had an opportunity to fly onboard one of these jets, writing a review of the experience here.

January 2021: A major acquisition

Then, at the start of 2021, Flair announced that it was taking on 13 737 MAX 8s from Boeing. These jets are coming to the airline through a lease agreement with a company called 777 Partners, an investment firm based in Miami with 25% ownership of Flair Airlines. As we had noted previously, 777 Partners had themselves recently signed off on purchasing 24 new MAX 8s directly from Boeing, with the option for a further 60 planes.

Commenting on the milestone order, Stephen Jones, President & CEO of Flair Airlines, said,

“Our efficient new aircraft will provide us the foundation to execute our ULCC business model. These planes will enable us to keep fares low while expanding our service to meet travel demand.”

On May 29th, Flair took delivery of the first of these MAX jets. Planespotters.net data showed that the nearly two-year-old aircraft held three prior test registrations (N1786B, N1799B, N1782B, N57001) before taking its current Canadian letters.

Since late May, Flair has taken delivery of four more MAX 8s with a plan to take delivery of three more MAX 8s in the next few weeks. While this will push the airline’s total fleet size to 11, the airline’s January announcement to take 13 MAXs means it will have an initial fleet size of 16.

Ultimately, however, the airline has a goal of 50 aircraft within its first five years of operation. A goal which it has ‘codenamed’ “F50.” The carrier is likely to keep quite close to the low-cost-carrier playbook, ordering more of the same type to reduce training and operational costs associated with fleet diversification.

Whitetail 737s

While somewhat ‘brand new,’ without any previous owners, Flair’s newest jets are around one-and-a-half to two years of age. This would indicate that the aircraft are so-called ‘whitetails.’ These are aircraft originally built for another customer but canceled at some point along the way.

The age of these aircraft would indicate that they were canceled due to the 737 MAX crisis, which stretched from March 2019 to early 2021.

With the MAX recertified by the FAA and Transport Canada, Flair is confident of the type’s safety. We would imagine that the leasing company acquiring the jets likely purchased them at a great price due to the MAX controversy and was thus able to pass those savings on to Flair.

While Flair’s fleet is certainly quite uniform (fitting with most budget airlines), its expansion in 2021 and anticipated growth over the next few years will certainly be exciting to watch.

Air Canada’s Fleet In 2021

From Simple Flying – link to source story

As Canada’s largest airline, Air Canada has a diverse fleet based across its four hub airports. The network airline has a mix of both widebody and narrowbody aircraft coming from both Airbus and Boeing. The carrier has gone through some changes in the past few years, with more significant upheaval taking place during the global health crisis. Let’s take a look at Air Canada’s fleet as it stands in 2021.

Air Canada’s fleet composition

According to data from Planespotters.net, Air Canada has the following aircraft in its fleet. The quantities are noted in parentheses.

Aircraft from Airbus*:
  • A220-300 (22)
  • A320 (18)
  • A321 (15)
  • A330-300 (16)

*We should note that the airline ordered the A220 when it was still known as the Bombardier CSeries.

Aircraft from Boeing:
  • 737 MAX 8 (24)
  • 777-200LR (6)
  • 777-300ER (19)
  • 787-8 (8)
  • 787-9 (29)
The average age of Air Canada’s A330-300s is 16 years. Photo: Air Canada

Outside of regular passenger service

There are aircraft within the Air Canada fleet that are outside of the airline’s passenger operations.

Notably, we have the airline’s private/charter subbrand, Air Canada Jetz. This sub-group consists of four Airbus A319s. This fleet traditionally consisted of three A319s, but it appears a fourth was added in December 2020.

Used to transport touring musicians, sports teams, or private groups, these aircraft have an all-business configuration of 58 seats. With the exception of a short pandemic run, these aircraft tend to stay out of Air Canada’s regular passenger operations.

As we will mention further in this article, Air Canada retired its 767s at the start of the health crisis. However, some of these are slated for a full conversion to freighters. The airline says that two freighters are expected to be in service in time for this year’s fourth-quarter peak airfreight season.

With seven 767s on the list for conversion, it looks like the remaining five will be converted next year, in 2022. This was confirmed by the carrier’s current Chief Financial Officer and future Chief Executive during the earnings call in which Simple Flying attended:

“We’d love to have all seven up and operating by the end of next year. These are typically little bit of a longer process and slots are not really available, but we are certainly working on having all seven up and running by Q4 of next year.” – Michael Rousseau, Chief Executive Officer, Air Canada

Coming and going

On the outgoing side of things, it was in May 2020 that Air Canada announced the early retirement of 79 aircraft. 

Retirements included five 767-300ERs, 16 A319s, and 14 E190s in the mainline fleet. Another 25 767-300ERs and 22 A319s that made up Air Canada Rouge were also retired.

Looking at future aircraft, Air Canada has a decent number of Boeing 737 MAX 8s and Airbus A220-300s yet to be delivered. There was a little bit of a back-and-forth when the carrier announced it would be canceling some of its orders last November. The plan would have seen the airline cancel orders for 12 A220s and 10 737 MAX 8s.

However, one condition of the carrier’s government rescue package was that it would proceed with its planned orders for both aircraft types. As it stands, 16 737 MAX 8s and 23 A220-300s are still on the way.

As you can see from the list of aircraft, Air Canada has a fairly diverse fleet- which is quite typical of a large network carrier that operates both short-haul and intercontinental service.

Flair Airlines Begins Service with the First of 13 New Boeing 737-8 Aircraft

The growing ULCC starts passenger service with inaugural flight from Edmonton to Toronto

EDMONTON, Alberta, June 10, 2021 (GLOBE NEWSWIRE) — Flair Airlines, Canada’s only independent ultra low-cost carrier (ULCC), begins service today with the first of 13 new Boeing 737-8 aircraft joining the fleet as the airline begins rapid growth to provide affordable, low fare air travel to 19 Canadian destinations.

“Today marks a huge milestone as Flair grows to bring affordable travel options to more Canadians,” says Stephen Jones, President and CEO, Flair Airlines. “Canadians have been paying too much for too long, and Flair is changing that thanks to the addition of the new 737-8 aircraft which provide us the efficiencies and ability to scale our service. Today’s inaugural flight kicks off our rapid growth.”

The inaugural flight of Flair’s first new 737-8 will depart Edmonton at 5:30pm MT and arrive in Toronto at 11:20 pm ET. Piloting the inaugural flight will be two veteran leaders at Flair: Captain Matt Kunz, Vice President, Business Transformation and Operations, and Captain Harold Knop, Regulatory Compliance and Certification Manager.

The new aircraft allow Flair to achieve the lowest cost per seat mile of any Canadian airline. The aircraft will deliver fuel savings and cut the airline’s CO2 emissions by 14%. Lower per passenger emissions are a vital step in lowering Flair’s carbon footprint as it works to become Canada’s greenest and most sustainable airline.

Flair’s pilots, maintenance professionals, flight attendants and safety officers have been conducting extensive testing and training programs to prepare for the addition of the new aircraft. Flair’s team has been working closely with Boeing and been on-site throughout the testing and delivery phase of each aircraft.

Flair began taking delivery of the 13 new aircraft in May. The 737-8 aircraft are joining Flair’s existing fleet of 737-800 aircraft and deliveries continue throughout 2021. By the middle of next year, Flair will have a fleet of 16 aircraft and be well on the way to achieving its “F50” ambition of growing to 50 planes within five years.

Air Canada Eyes The A321LR As More A220s Set To Be Delivered

From Simple Flying – link to source story

by Jake Hardiman | May 7, 2021

While Air Canada does fly the Boeing 737 MAX series, most of its narrowbody aircraft belong to Airbus families. These include the five-abreast A220 series, of which the airline is set to receive a further 15 examples by the end of 2022. Interestingly, the Canadian flag carrier has also revealed an interest in Airbus’s long-range A321LR model.

Four A220s delivered in Q1

Air Canada announced today at its first-quarter earnings call that it has continued its short-haul fleet modernization despite the industry’s present challenges. The Airbus A220 is leading the way in this regeneration, with Air Canada favoring the A220-300 variant.

This next-generation narrowbody has won favor among both employees and passengers for its enhanced efficiency and comfort levels. According to Planespotters.net, Air Canada presently has 19 137-seat A220-300s in its fleet, of which 17 are active. Of these, more than 20% arrived in Q1 of 2021. Indeed, the airline confirmed on the aforementioned call that “we took delivery of four Airbus A220 aircraft in the first quarter.”

These four first-quarter arrivals came in the form of the following aircraft.

Next 15 deliveries also secured

The introduction of the A220 has played a significant role in the regeneration of Air Canada’s short-haul fleet. The type will replace its remaining A319s, which have an average age of 24 years. Amid the pandemic, it has not been unusual to see carriers defer orders. However, regarding its remaining A220s, the airline confirmed that:Advertisement:

“In March 2021, Air Canada concluded a committed secured facility totaling US$475 million to finance the purchase of the next 15 Airbus A220 aircraft scheduled for delivery in 2021 and 2022.”

Potentially a place for the A321LR as well

In the longer term, Air Canada will be hoping that it can resume its longer-haul services to transatlantic destinations such as the UK and mainland Europe. However, ongoing uncertainty remains regarding different countries’ restrictions and vaccination rates.

As such, it may not see the demand levels that it had become accustomed to before coronavirus. With this in mind, the airline is open to trying new aircraft types in order to adapt to market fluctuations. For example, it stated that:Advertisement:

We’ve done a pretty good job covering ourselves for growth beyond our expectations, but certainly also for even further fine tuning. (…) That gives us the opportunity to then potentially step into new types of aircraft. Like the A321LRs, for example, that we like, and that certainly have a potential place in Air Canada’s fleet as we go forward.

Of course, the carrier would not be the first Canadian airline to deploy this long-range version of the Airbus A321neo series. Indeed, Air Transat, whose merger with Air Canada was recently canceled, has operated the type since 2019. Last October, Air Transat even set the record for the world’s longest flight using the aircraft.

This saw it fly non-stop from Montréal, Canada to Athens, Greece. This represented an impressive distance of 7,600 km (4,100 NM), although it has since been beaten by Azores Airlines. Nonetheless, with the aircraft being an ideal fit for ‘long thin’ transatlantic markets, Air Canada’s interest is understandable. 

New 737 Max issue affects nearly two dozen airlines, 106 jets: FAA

From Flight Global – link to source story

By Jon Hemmerdinger | 23 April 2021

The US Federal Aviation Administration has disclosed new details about an electric problem that forced the grounding of more than 100 recently-produced Boeing 737 Max.

Though the issue primarily affects jets delivered by Boeing after the FAA lifted the grounding in November 2020, several Max delivered before the grounding are also affected, according to the agency.

Regulators globally grounded the Max in mid-March 2019.

The issue involves “potential degradation of bonds associated with electrical grounding of equipment that could affect the operation of certain systems”, says the FAA in a 22 April “Continued Airworthiness Notification to the International Community”.

Potentially affected Max systems include standby power control units, “P6” circuit breaker panels and main instrument panels, it adds.

Boeing notified the FAA about the concern, which it discovered “after electrical power systems did not perform as expected during the testing of a newly manufactured Model 737-8 airplane,” says the FAA’s notice.

Chicago-based Boeing publicly disclosed the problem on 9 April but did not specify how many aircraft were affected. Boeing recommended airlines pull affected jets from service.

The FAA’s 22 April memo specifies that the problem affects 106 737 Max 8s and Max 9s, including 71 in the fleets of US airlines.

Those jets have manufacturing line numbers between 7,399 and 8,082. Boeing manufactured them after making design changes in “early 2019”, the FAA says.

Of the 106 aircraft, Boeing delivered 18 in early 2019 prior to the global grounding, according to Cirium fleets data.

Operators with affected jets include four large US carriers: Alaska Airlines, American Airlines, Southwest Airlines and United Airlines.

Others are Air Canada, Belavia, Blue Air, Cayman Airways, Copa Airlines, GOL, Icelandair, Minsheng Leasing, Neos, Shandong Airlines, SilkAir, SpiceJet, Sunwing Airlines, TUI, Turkish Airlines, Valla Jets, WestJet and Xiamen Airlines, says the FAA.

“This issue is not related to recertification of the flight control system on the 737 Max, un-grounding of the aircraft, or its return to service,” the FAA’s notice says. “All affected in-service airplanes passed all testing prior to delivery and there have been no reported in-service failures due to this condition.”

Air Canada and Government of Canada Conclude Agreements on Liquidity Program

Air Canada A220-300 C-GROV

  • Financial package makes available repayable loans and equity

MONTREAL, April 12, 2021 /CNW/ – Air Canada announced today that it has entered into a series of debt and equity financing agreements with the Government of Canada, which will allow Air Canada to access up to $5.879 billion in liquidity through the Large Employer Emergency Financing Facility (LEEFF) program.

“Air Canada entered the pandemic more than a year ago with one of the global airline industry’s strongest balance sheets relative to its size. We have since raised an additional $6.8 billion in liquidity from our own resources to sustain us through the pandemic, as air traffic ground to a virtual halt in Canada and internationally,” said Michael Rousseau, President and Chief Executive Officer of Air Canada. 

“The additional liquidity program we are announcing today achieves several aligned objectives as it provides a significant layer of insurance for Air Canada, it enables us to better resolve customer refunds of non-refundable tickets, maintain our workforce and re-enter regional markets. Most importantly, this program provides additional liquidity, if required, to rebuild our business to the benefit of all stakeholders and to remain a significant contributor to the Canadian economy through its recovery and for the long term.

“As vaccine deployments ramp up, we continue to work with the Government of Canada on the evolution of safe and science-based test and quarantine relief measures with a view to safely restarting our sector. We know that Canadians are looking forward to re-connecting with friends and family and taking those long-awaited vacations and business trips and we will be ready to safely connect Canadians within Canada and Canada to the world,” said Mr. Rousseau.

The financial package provides for fully repayable loans that Air Canada would only draw down as required, as well as an equity investment, and is comprised of:

  • Gross proceeds of $500 million for Air Canada shares at a price of $23.1793 per share;
  • $1.5 billion in the form of a secured revolving credit facility at a 1.5% premium to the Canadian Dollar Offered Rate (CDOR); the facility is secured on a first lien basis by the assets of Aeroplan Inc., Air Canada’s shares in Aeroplan as well as certain assets of Air Canada, including certain intellectual property relating to the Aeroplan loyalty program;
  • $2.475 billion in the form of three unsecured non-revolving credit facilities of $825 million each with: the first, five-year tranche at a 1.75% premium to CDOR per annum; the second, six-year tranche at 6.5% per annum (increasing to 7.5% after 5 years); and the third, seven-year tranche at 8.5% per annum (increasing to 9.5% after 5 years);
  • As part of the financial package, Air Canada issued an aggregate of 14,576,564 warrants exercisable for the purchase of an equal number of Air Canada shares, subject to customary adjustments, at a price of $27.2698 per share during a 10-year term, representing 10% of the total commitment available under the above secured and unsecured credit facilities; 50% of the warrants vested concurrently with the implementation of the credit facilities and the remaining 50% of the warrants will vest on a proportional basis to the amounts that Air Canada may draw under the above unsecured credit facilities;
  • Up to approximately $1.4 billion in the form of an unsecured credit facility tranche to support customer refunds of non-refundable tickets. The facility will have a seven-year term and carry an annual interest rate of 1.211%.

As part of the financial package, Air Canada has agreed to a number of commitments related to customer refunds, service to regional communities, restrictions on the use of the funds provided, employment and capital expenditures. These include:

  • Beginning April 13, 2021, offering eligible customers who purchased non-refundable fares but did not travel due to COVID-19 since February 2020, the option of a refund to the original form of payment. In support of its travel agency partners, Air Canada will not retract agency sales commissions on refunded fares;
  • The resumption of service or access to Air Canada’s network for nearly all regional communities where service was suspended because of COVID-19’s impact on travel, through direct services or new interline agreements with third party regional carriers;
  • Restricting certain expenditures, and restricting dividends, share buybacks and senior executive compensation;
  • Obligations to maintain employment at levels which are no lower than those at April 1, 2021; and
  • The completion of the airline’s acquisition of 33 Airbus A220 aircraft, manufactured at Airbus’ Mirabel, Quebec facility. Air Canada has also agreed to complete its existing firm order of 40 Boeing 737 Max aircraft. Completion of these orders remains subject to the terms and conditions of the applicable purchase agreements.

In connection with the Government’s equity investment, Air Canada has agreed to provide customary registration rights. The Air Canada shares and warrants issued to the Government are subject to certain transfer restrictions as well as an exercise cap which limits the Government’s aggregate voting rights from the shares acquired pursuant to this investment (including upon any exercise of the warrants) to 19.99%.

WestJet, Sunwing warned by Boeing to inspect some 737 Max aircraft for possible electrical problem

From The Globe and Mail – link to source story – Updated from previous story

ERIC ATKINS, TRANSPORTATION REPORTER | APRIL 9, 2021

The 737 MAX is a fourth-generation Boeing 737, re-engined with CFM LEAP-1B turbofans – wikipedia.org

WestJet Airlines and Sunwing Airlines are among 16 operators of the 737 Max warned by Boeing Co. to ground and inspect some aircraft for possible electrical problems.

Boeing has told the airlines to examine certain models of the Max for potential problems related to a component of the electric power system.

Morgan Bell, a WestJet spokeswoman, said the plane – one of 14 737 Max in its fleet – has been pulled from service. “Any maintenance, if necessary, will be completed before the aircraft returns to service,” Ms. Bell said. “WestJet’s additional 13 737 MAX aircraft are not affected.”

Sunwing said two of its four 737 Max are affected by the suspension. “We have been informed by Boeing that two of our 737 MAX planes may be impacted by the potential electrical issue,” said Melanie Filipp, a spokeswoman for Sunwing, which grounded all flights on Jan. 31 due to the pandemic.  “We are awaiting further direction from Boeing on actions to be taken prior to operation of the specified aircraft.”

The 737 Max was cleared to resume flying in Canada in January after it was grounded worldwide for about 20 months after two fatal crashes killed 346 people. The pilots lost control of the planes shortly after takeoff – problems that were linked to the model’s Maneuvering Characteristics Augmentation System (MCAS).

Canadian, U.S. and other regulators studied and approved the software changes Boeing made before allowing the model to resume service.

Ivan Gale, a Boeing spokesman, said the electrical problem in the new safety warning is not related to the model’s MCAS. “We are in contact directly with the impacted airlines,” said Mr. Gale, who declined to name the carriers.

Boeing did not say how many planes are suspended.

Southwest Airlines removed 30 MAX airplanes from its schedule Friday, while American Airlines pulled 17 of its 41 MAX models. United Airlines removed 16 of its 30 MAX airplanes and Alaska Airlines four aircraft.

An Air Canada spokesman said none of the carrier’s 24 737 Max is affected.

The U.S. regulator, the Federal Aviation Administration, said it will ensure the issue is addressed. Transport Canada did not respond to questions on Friday.

The fatal crashes that spurred the global grounding in 2019 involved Indonesia’s Lion Air in October, 2018, and Ethiopian Airlines in March, 2019.

WestJet’s Ms. Bell said the new grounding has not changed the carrier’s favourable view of the 737 Max. “WestJet has safely operated the 737 MAX since its return to service on January 21, 2021, and the airline has full confidence in the safety of the aircraft,” Ms. Bell said.

The 737 Max is a new version of a plane that first flew in the late 1960s. Updated with bigger engines and other modifications, the model became a best-seller after being introduced in 2011 due to its longer range and low operating costs.
