I will have a few hours in Houston (IAH) before a flight on AA. I do not see an AC lounge. I have an American Express Platinum Business card and am EXP. Is there a lounge that I will be eligible to go to?
Nothing convenient that I'm aware of. Terminal D has a few lounges and if you have the PPass from the AmEx I think you can get in to the one in Terminal D but otherwise the lounge situation there is pretty much all UA.
There isn't much of anything in Terminal A at IAH. Only good part is security is quick and it's not very crowded...unlike the term C madhouse.
