Sorry, wasn't quite sure where to put the post... Thanks for responding so quickly. It did sound like a fishy notion anyway, so it's not surprising that it can result in loss of benefits.

I just wanted to know, because I'm booked on ATL-DFW as revenue, because my parents are divorced so when I travel with my father (an employee) or alone it's NRSA, but with my mother it's generally revenue. I just wanted know, because I would have made an NRSA booking in addition just to get F if it was available, as I knew I wouldn't be upgraded as I hold no status.

Figured it was best to ask first, as I couldn't find anything definitive anywhere else (turns out it wasd best to do so). Thanks again.
