and yet, you, swamt, are salivating at the prospect that DL will be forced out of DAL.
Hope you have something else to suck on to keep your mouth wet because DL will be at DAL.
yes, robbed, I am aware that US pushed WN into submission at PHL - because WN has never really liked competing directly against legacy carriers although will when the legacy is weak enough but find it ever harder to compete against legacies now that WN's costs are so much higher than they were in the past.
WN's expansion into DEN and PHL both occurred when WN was living off the benefits of its fuel hedge gains while other carriers didn't have any.
that situation doesn't exist and very likely will not occur again.
DL isn't the only carrier that can push back on low cost carriers but DL has been more consistent in protecting its hubs and major markets including former hubs from low fare carriers than any of the other legacy carriers.
