I opened the AA Citi Executive World Elite Mastercard and am close to my $10,000 spend for the 100,000 miles. I need to book a one-way domestic flight (for 6) that will cost me about $1500. I'd like to fly American to check out the admirals club, free checked bags and enhanced airport experience. Do I need to actually pay for the flight with the AA Citi card (and get 2 points per dollar) or can I put it on my Amex Gold (at 3 points per dollar) and still use the airport benefits? Thanks for any advice!
