Maybe my input to this is unwelcome.. but I'm gonna give it anyway.. and not flaming either.
Personally as a student of the industry, SWA would not be a top choice of mine if I were looking for a job because I really believe they have reached their maximum potential with the model they have. Without drastic changes to that model, they are not gonna grow much. I can't see how they could. The model has already been violated by adding the second type (which I believe Gary Kelly is desperate to unload).. and high density airports. Where else can you find city pairs like you had in the past?
That being said, DAL/UCAL and whatever arises from AA/U (which will be interesting) have a lot of room to run. DAL's biggest money maker right now is domestic. How can that be when SWA is THE low cost airline? Sorry for the tangent. If I were a senior guy at SWA I would be happy as you stated you are. The prospect of throwing gear on a 737 for an extended length of time.. vice throwing gear on a 747, would not appeal to me as a young guy.. especially when that pay premium that you have enjoyed for the last few years is going away. Variety is the spice of life, but to each his own.
I think that very young/junior guys are always talking about going somewhere else. That is a natural thing. When we were in BK, we had guys TALK about going to Emirates.. I even thought about going to Cathay.. until I found out what it was like there.. grass... greener... yada yada yada. But when it really comes down to pulling the handles, THAT is a different story. Not much different than all those guys that say "I'm retiring at 55".. yeah right... sure they will....
