I should also add that buying VX was worth it to prevent B6 from having a west coast hub.
I wouldn't be too surprised for AS to reduce frequencies on or close some of the LAX transcon markets and move planes to SEA/PDX/SFO, partly because they no longer offer a competitive transcon product and partly to withdraw from AA's backyard in LAX. It's anti-competitive, but possible to explain it to regulators as the airline shrinking due to COVID.
With AS trying to get rid of the Airbus aircraft as soon as possible and the MAX grounded, AS won’t have those planes to move to SEA/PDX/SFO. Cutting their weakest flights makes sense. Better to keep flying routes where they are more likely to be competitive and toss the rest.
