Uh, generally, my spelling and grammar are good? (Forgive the correction if this is one of those US/UK singular/plural differences.)
when I was a federal employee it was illegal to use frequent flyer bonuses of any type.
They changed that a decade or more ago. The theory is, since these programs and benefits are offered to everyone, they aren't considered a "bribe" to government employees. In practice, I think allowing use of these benfits still increases unnecessary travel and travel costs (due to individual loyalty to particular airlines/hotel chains which aren't always the best choice from the government standpoint).
