Hello... I have the AA Citi Executive MC and it included all the good benefits (priority boarding, free 1 piece of luggage, etc) along with the 100K miles. I've never used the AA specific benefits (priority boarding, etc) so I'm looking for feedback on those that have used them... Have you encountered any push back? Do you just flash your card and get on the first class check in counter? Have you encountered any agents who didn't know the benefits? Do you go through the fast TSA lane? Any feedback would be greatly appreciated. Thank you.
