Hard as it will be for anyone who's read my novice questions here at Milepoint, I actually got a call from a friend last night seeking advice on an airline booking question — as if I were an expert or something. Nothwithstanding the fact that that alone probably means my friend in doomed, I thought I'd find out if anyone here knows the answer. My friend is booking flights on Turkish Airlines for this summer. His family is flying out together, but back at different times. He was able to book the single person who's flying back earlier but hit a roadblock trying to buy the other three tickets. That's because the Turkish Airlines system would not accept his credit card because the expiration date on the card is during the period he'll be travelling. (Seems odd to me since the purchase of the ticket will long since have cleared six months from now, but hey, when in Istanbul. . .). The other card he wanted to use to purchase the remaining three tickets is in his wife's name and she's the person travelling home earlier. The question is, will he and his kids be able to board their returning flights on tickets purchased with his wife's credit card without being able to present the card (and the wife) while checking in? I know this is an issue on some airlines. To further complicate matters, of course, he and his wife don't use the same last name. Any advice gratefully received (and will certainly boost my undeserved reputation as a travel guru).
