LAX is one of the biggest origin/destination markets in the country. This means a lot of airplanes starting/finishing their day there. The cheapest crews to do these flights are LAX based because there are no hotel costs.
This means that a high percentage of LAX trips(on any domestic category) will have early shows and/or late releases.
LAX is also a prime place for redeyes. Redeyes are ideal trio starters in the optimizer’s view because, again, no hotels. Therefore, a lot of LAX trips will start with redeyes.
The takeaway here is that LAX is not an ideal commuter base because of the nature of the flying and RCC attempts to fundamentally alter LAX rotations are likely to be short lived because they are swimming against a powerful current.
I don’t see that changing in the near future so bid accordingly.
