3/ Southwest is highly unusual. Their IT is almost entirely homegrown, with software they built themselves. It's creaky and antiquated - you'll observe this if you watch their schedules. They're irregularly and manually loaded into the system.
The majority of airlines use standardized reservations systems like Sabre, Amadeus, etc. which integrate well with other standardized tools. Not Southwest, who only supports limited integrations in specific circumstances.
6/ So, about aircraft positioning and crew scheduling - Southwest is essentially a short and medium haul airline. They mostly don't do long haul services except for Hawaii.
Southwest turns aircraft quickly, in less than 30 minutes. They have higher aircraft utilization than any other major US airline. They often run their crews on tight loops where they're out from home and back the same day so they can save money on accommodating crews who overnight away from their home base.
7/ Yeah, about that. So when Southwest melted down, they didn't have nearly the number of rooms reserved that they needed for their own crew, and it was Christmas so hotels were full. Crews often did not get rooms. They just got dumped like passengers at airports. At least there are crew break rooms at most airports, but it's not very comfortable.
Major airlines usually have enough hotel relationships to be able to work something out (American has had some issues too) but Southwest does not.
11/ One way they could handle it is already proven, it's just expensive: holding crews and aircraft in reserve to recover from irregular operations. Qantas successfully does this.
A week ago, Qantas had an A380 unexpectedly land in Azerbaijan.
They thought there might be a fire in the cargo bay so they landed in Baku. It turned out there was a real problem with the aircraft and it couldn't be promptly repaired in Azerbaijan, a country which doesn't frequently see A380s. https://www.theguardian.com/business/2022/dec/24/qantas-sends-rescue-flight-to-azerbaijan-after-stranded-passengers-left-in-the-dark
15/ One last piece of airline trivia before I leave you all to digest this thread. American Airlines cancelled less than 1% of its schedule yesterday. Southwest cancelled over 70% of its schedule.
Southwest will likely (successfully) claim that under the Contract of Carriage, they do not have to pay for stranded passengers' hotels. Keep this in mind any time that politicians show up saying that every problem will be fixed with tort reform to keep evil class action lawyers from driving up costs.
Southwest has already admitted that the cancellations in the last days were controllable. Given that they updated their customer service plan a few months ago to include hotel vouchers passengers might get more money than they'd have a year ago in the same situation.
Given the amount of mess there are in and the huge number of passengers affected I'd guess it will take some time to get the compensations out. They'll probably have to build some new process to handle that efficiently and getting people unstuck should have priority.
@indri If I have to guess, the process will be to send a bunch of insurance company letters. You know, the ones that are really nice, talk in circles, and say they're "unable" to pay. Maybe include a $200 expiring airline voucher along with it (that's usually what Southwest does).
Being Southwest, though, they will capitalize things that ordinarily shouldn't be capitalized throughout the letter, in order to sound more like Hunter S. Thompson.
It remains to be seen, but it will probably depend on how often the CEO wants to receive calls not just by DOT staff but by a really pissed Transportation Secretary.
