I'll just add from this side of the fence we are as shocked as you with how poorly this is being executed. Buying jets your giving away at fire sale pricing to a competitor? Let alone the breach of trust on both sides of the isle. This is not the SWA we were hired at to be a part of a family, we have become a means to an ROI statement.
Yes, it would seem that sending the 717's to Delta is allowing them to step on the gas while SW is stepping on the brakes. Maybe SW is losing interest in Atlanta? I also don't understand the -800 delays, that aircraft was supposed to lower CASM and increase efficiency. It seems that very recently the CEO was singing it's praises and talking about what an important part of the future it was.
