Well, my 2¢ worth:
I'll be 50K E for next year.
Already, with the change to the T+ fares, I am flying UA more. Full miles, cheaper price, have my Nexus card so USA is less hassle.
Had e-credits expire last year and will have more this year go.
I lose preferred seating next year.
I have been weighing moving to UA plan next year. I think it might make sense for me to do this. I usually fly to Asia. I won't pay the T+ fares. So maybe UA makes sense for me.
<sigh>
