Alpa,
You are conveniently stating that we would only have 9 pax on us from, say, BOI to SEA if we started a 73 or Mad Dog on that route. Would there not be any pax at all that would bail off AS to go on us? I say there would be some, not all, but some and that we could compete with our mainline product very well against AS if we had to. Heck, just turn on the AC when the cabin gets hot alone would bring some of their pax to us.
Have ridden on them LOTS and have been in the back sweating both before and after the flight cuz they do not turn on any air until right before push and it is off shortly after block in.
