Here's something that has always worked for me. Give it a try, as it might work for you too. If mileage isn't added to your frequent flyer plan, either automatically when booked, or when you ask a ticket or gate agent for the courtesy, try writing a one paragraph letter, to the airlines' frequent traveler program, mentioning to them that on such and such a date, you flew on such and such a flight, and would they please apply the mileage. With the letter, and this is the key, include either the eticket, or a copy of it, or the boarding pass for the appropriate flight. I've never had them refuse that method, in fact I keep a few of these letters on my computer and just change the appropriate information, and send it off. Oh, and don't forget to include your frequent flyer number on the letter.
