Well, I was originally considering both of those airports, one for the way there and the other on the way back because they fit with our times and were CO. BUT, I got the most UH-mazing CO customer service rep on the phone that managed to get my DH switched to my non-CO nonstop flight there (upgraded to first with no change fee) as well as switch us both to the MCO-IAH-PHX on CO back (1hr 17 min layover), but with no increase in miles even though only Easypass has been available, AND let me book my son's ticket over the phone with her with no phone booking fee. ^^^
Needless to say, I WILL be writing a glowing email about her to someone as soon as I figure out who I should write to!
Anyway, since I can check bags free on CO and we're just going home, I think I'll just unload what I can to minimize my carryons since we'll have sleepy children. I won't really care if our luggage is delayed.
