Thanks for your replies...the reason I asked the question was in my town of West Hollywood, California, I've uncovered a practice where some City employees were going out of their way to take certain airlines, usually at HIGHER cost than necessary, to earn FF miles. I have no problem with that if I'm paying for the ticket, but people traveling with the Public's money shouldn't be allowed to do this. I think the only way to stop this kind of taxpayer waste is to prohibit it, and enforce that policy. Jim
