I wouldnt fly TA, simply not on the same level as AA or CO

if AA is going through MIA forget it.........the return (dealing with immigration etc) is crazy

I havent flown AA F via DFW , I fly CO F all the time and they are very good , plus IAH is a good airport to go through

you would have access at the Presidents Club at both SFO and IAH since you are flying international F
