thx for the helpful replies. I'm gonna assume I'll be fine with 60 min for a Mon 7 am flight.
I'm returning through PHX on Sun at around 5:30 pm, carry-on only, no status except with oneworld. I've never gone through immigration in PHX but no checked luggage usually helps quite a bit with time. (Unless I'm in ATL -- good god, that airport was as chaotic as MIA).
