While buying a ticket online this week I got repeated error messages telling me the name on my credit card and security information — i.e., how my first name is expressed — have to match. I had to call to buy the ticket over the phone. The AA CSR told me she's been hearing about this problem recently. I tried the AA X (Twitter) team, which is usually pretty responsive, but they ducked the issue. Anyone else experienced this? I'm not going to change the name on my credit cards. The alternative is... Delta?
