As I said, many of these are routes they flew before and then eliminated. This, of course, is the long history of attempted competition at PHL. It never works. Maybe it should, but it doesn't. And, to my knowledge, no large ultra low cost airline has ever succeeded with infrequent "friends and family" routes. Sure, it can work in oddball markets like mainland to Puerto Rico, but it's highly unlikely to work between Philly and Kansas City. Let's come back in a year and two and see what happens.
