Both bases have had recent recallees getting awarded them. I'd say LAX/ORD would be available within a few months of hiring on - if that trend continues. Keep in mind, Parker has said on multiple occasions that LAX will grow. ORD is kind of in limbo right now, but there is enough movement that creates openings for relatively junior folks on the 737 and -80.
Just as an example, DFW in the past had always taken several months, if not years to get to.... This last new hire class had EVERYONE get assigned DFW -80.
Motto, things change quickly with movement.
Congrats to all those getting the offer!
