Ditto on registering for several airline dining for miles programs with different credit cards. I keep track of receipts by keeping them in separate files for each frequent flyer program. I keep a list all my credit cards which indicates the dining for miles program that they are registered for, and in addition, I put a sticker on each credit card with the airline name written on it.
