I havent looked back since switching to UA last year (still CO Plat for '10)
Ive flown UA even to SYD in E+ and had no problems while having just gotten off a CO Intl flight in Coach on the 777, I was praying that CO goes E+.
there arent that many ELR seats and with the merge now history theres gonna be alot more UA people gunning for the ELRs , so if no UP occurs and youre flying CO tehres a very good chance of being stuck in E-
Now if CO doesnt go E+ and they remove it from UA as well, then time for me to move onto another Carrier
E+ is that good, and on the rare occasion when I was on a 319 with 8 F seats and didnt clear to F it was very nice knowing I was gonna be in E+ with the leg room that I need
