With how the program has already been cut and what looks to happen in the near future I already know that within 3 yrs DL will no longer be my only airline of choice.
Rollovers have kept me in the game a little longer, otherwise I would already be gone.
I don't hold any ill feelings, just won't chase status as it no longer makes sense. That being said it never made sense to me to get on a plane for 10+ hrs to just get back on another home on a mileage run just for status.
I have to wonder how many others are in the same boat and where DL is feeling really good about itself right now, they may have a hangover in a few years.
