Adding w/b flying didn't mean it would be based out of PHX. If PHX got a long haul trip, or two, it probably would be flown as a six day trip from another base.

I'd put SW down as more stable in PHX. $.02

Would I pick SW over AA? No. I think SW is a great company but there's a reason so many guys at AA go fly the w/b's, even if they have to commute to them.

Here's an idea of how guys actually bid -
top 1000 CA's - 87% on w/b's
top 500 CA's - 94% on w/b's
top 200 CA's - 97% on w/b's
top 100 CA's - 100% on w/b's

Top 285 FO's, all of whom could be a G4 CA (777,787,330)? 275 are FO's on the G4 aircraft, one is on the 767, and 6 are on n/b's.

They're living it. They not picking narrow body flying for a reason.
