If that happens I am guessing it might be a good idea not to reveal myself to the airline through my frequent flyer identifier.
In such a case, could be a good idea to provide the number after all the flights have been taken?
Can you think of any other scenario when it's beneficial NOT to provide your frequent flyer number before the flight?
Wouldn't it just be easier to assure your credit for the flights you did fly by having your FFN on the record, and just not fly the return? They already know who bought and ticketed, and if they're actively searching I'm sure the FFN won't make a critical difference in doing so. (After all, you are talking about "throw away ticketing"; given the price on a one way US <-> Europe ticket, often considerably more than a round trip in many instances, I'd be surprised if they're surprised people did this.)
