I fly a lot. And I used to not mind flying on Delta, despite the fact that their flights rarely take off on time and seem to always be overbooked and have flight attendants who would never win Miss Congeniality. And other than MSP and a few newer shared terminals, the Delta terminals are overcrowded crap. But then to add insult to injury, they changed their partnership rules with other carriers. Now I pay for a bag to avoid checking at the gate or having somebody crush my stuff with their overly large "carry-on." No SKY privileges anymore. I know, I know...that seems really whiny; but when somebody takes it away suddenly...man, it stings. So why would I choose this airline when I can have an equally poor experience from another airline for a cheaper price, or a better flight for the same price? The obvious answer is, I wouldn't.
