Didn't have a terrific experience in "regular" economy on Delta for Cat Fight last year on the way home - VERY tight - but I think that's true for all of them now. I have status with UA so I always get Economy Plus. Disney also has Delta as a preferred airline now so I may try to start booking more in the that direction so I can gain some status.

The flight options stink from the Left Coast - we are almost always stuck on red-eyes...
