Beware of citi bank aadvantage credit card. It's completely a bait and switch. They offer you priority boarding and priority luggage by signing up for the card but this is not true. I'm at the airport right now with my credit card and advantage miles number and no one can link the reservation to my card because i didn't pay with it.
Customer service in the airport and on the phone are selfish uneducated people who hate their job.
Do not sign up for this card!!! BTW, I've got over 80,000 miles with this airline and they are unwilling to accommodate me at all and the flight isn't even full.
Looks like I'll be paying this one off and canceling it.
They've lost a customer for life.
