I'm returning from lurking to pose a question to the FT community since i can't find the answer in my searches.

If I am flying in a group, and members of the group do not have FF numbers or do not want FF numbers (gasp), am I able to put my own FF number on their ticket? Will i actually get credit for the second (third, etc.) pax on the number?

Thanks, and if this has in fact been discussed before, please direct me to the thread.
