actually, if the E you are referring to is the forums user who posted in this thread, he has steadfastly maintained that DAL would have little affect on AA and that DAL is really too small of an operation to have much of an impact on the N. Texas market.
I am the one who has repeatedly said that DAL and DCA would be a huge opportunity for WN -but because you are fixated on trying to prove me wrong, you have missed all of that.
LUV is doing well because the entire industry is doing well, because WN is starting service in a number of high profile markets where yields have long been high, and because WN is pushing its costs down by using bigger aircraft.
Problem is that you can't admit that those bigger aircraft make a lot of routes to smaller cities no longer viable or if they remain, they will be at frequencies far below what business people will accept.
WN is cutting frequencies in dozens of markets including in ATL where adding 30 more seats to the aircraft will do nothing to convince business people to fly with them but eliminating a frequency or two in a market will make their schedule much less viable.
And as much as you want to believe otherwise, service that is cut won't come back in the future.
WN will do well but you can't seem to accept that they are walking away from key parts of what built them, they are stretched very thin trying to serve too many markets, and they don't have the cost advantage to push against the legacy carriers that they once had.
