As an over 55+ guy, previous 121 PIC time, 9E is appealing to me mainly because of the new base which is driving distance and the fairly quick upgrade. Flow at AA is not really a consideration for me, although PSA base is also a drive away. So it's going to be a toss up between the two, followed by RAH. OTS hire at a legacy or LCC such as WN or F9 would be even better.
