Would Southwest Ever Operate Another Type Of Aircraft?

In late April, the internet was abuzz with speculation that Boeing-loyal-airline Southwest was considering aircraft from Airbus. The idea that an airline is shopping around for aircraft wouldn’t normally be big news, but because Southwest is an all-737 fleet – the world’s largest operator in fact – the aviation community took notice. So the question of the day is: Would Southwest ever operate another type of aircraft?

Boeing Loyalty

As the website The Air Current and many other sources report, an unwritten deal stands between Boeing and Southwest. That deal says:

“No airline on Earth would ever pay less for a 737 than Southwest”


In fact, the co-founder of the airline once told The Wall Street Journal:


“I doubt that there’s any relationship like it in the history of the airline industry”.

Looking back over the years, that statement rings true as 777 Boeing 737s (various generations) have come directly from Boeing. Of course, the second-hand market has provided the others.

Airbus visit: “unfortunate timing”

But despite the fierce loyalty and the huge benefits that come with operating a single-type-fleet, there’s still the question of what happened in April, when Southwest made a visit to Airbus. The Dallas Business Journal reported what Southwest Chief Executive Gary Kelly said during an earnings call just after the reports,

“I want to be very clear — the timing is a bit unfortunate…And I’ve read speculation that it’s intentional on our part to perhaps consider a change from our current direction with Boeing and the Max, and that is not true…We didn’t reveal that we took this trip…That was a leak by somebody. Again, I just wanted to point out we’re not trying to send any message whatsoever.”

During a Dallas luncheon in April, Kelly is quoted as saying Southwest has “no plans” to alter orders for hundreds more 737 MAX jets.

The impact of the grounding so far

However, those comments were made in April when there was perhaps more optimism that 737 MAX issues would have been fixed sooner. Primarily, in-time for the busy summer travel season. To date the airline has had to make the following adjustments:

With continued uncertainty regarding the lifting of the ban, could Southwest change its mind? It would have two good reasons to “mix things up”:

  • Manage future risk: in case another issue arises with one type of aircraft, the fleet diversity would allow it to continue service.
  • Retain customers that are loyal to Southwest but remain dead set against flying on a 737 MAX (even after it’s approved to fly again). This may be a minimal factor.

Not anytime soon…

Even if Southwest were to place an order with Airbus for the 737’s competitor, the A320, the backlog is enormous. Southwest wouldn’t get its order until long, long after the announcement was made.

According to Defense and Security Monitor, on June 30th, 2019, Airbus’ backlog was 7,276 jets (of which 6,344, or 87%, are A220 and A320ceo/neo family narrowbodies). FlightGlobal reports that Airbus has a monthly production target of 60 (which is set to rise to 63 in 2021 and 65 in 2022). The Defense and Security Monitor does the math and makes it clear:

“The number of Airbus aircraft to be built and delivered represents 9.1 years of shipments at the 2018 production level.”

So looking at the numbers in combination with Southwest’s longstanding loyalty with Boeing, it just seems unlikely that the airline would want to damage the goodwill it has built up with the manufacturer over the past few decades.

Boeing rewards Southwest with exclusively low pricing and could (or at least should) compensate the airline because of the hits it has taken due to the MAX crisis.

What do you think of this assessment? Is there something that’s missing when making the analysis? Let us know by leaving a comment!

There is only two ways that SWA would consider flying another type;

1) The Max does not regain certification


2) SWA customers do not fly on the Max. Ever. No airline can afford to fly empty aircraft…


With regard to the caption in this article that “A321 production capacity could be taken from A380 production space”, this very topic was reported yesterday on Reuters:



The “exclusively low pricing and could (or at least should) compensate the airline because of the hits it has taken due to the MAX crisis”, may be related but are two separate issues, and they deserve compensation.

BTW, I don’t see any airline statements regarding changing future orders of the 737 MAX.


With fly by wire pitch control, a new type rating and a new name, the Max could be acceptable to the public, buying time while Boeing produces a state of the art replacement for the 737. The new type rating would not be that expensive and a good bridge to the type rating of the sate of the art replacement for the 737.

The Max has lower CO2 emissions than previous 737 models, but is not nearly as efficient as the A220 and 787.

In addition to the 63 A320 family Airbus are aiming for 14 A220. Thus 77 all up. Shorter waiting times for A220 than either A320 or B737.

Liam Doyle

Once the 737MAX is flying again and has no issues for the next couple of years the whole MAX debacle will be long forgotten by the flying public.


Depending on price.

What is unmentioned in the article is the A220 as a potential alternative. It is even more fuel efficient than the A320 Neo. Its order backlog is not that big and with rising fuel prices the A220 will be an attractive alternative for Southwest. A stretched version will likely be presented soon. Remains to be seen whether Airbus is able to ramp up production in Mirabel and Mobile.
