it would make the decision of flying AA mainline and paying to upgrade to first and their fantastic service on first where you get a MEAL in first which is always fun
or flying UAX and anyone who says explus first is similar to mainline first is nuts I just prefer to fly on ual mainline but I will fly on uax if i have to or want the miles
i will probebly spilt it and do 2 trips on United Express and one on AA mainline
