[Butch Cassidy Slept Here]

Assuming for a moment that the tickets in question were obtained legitimately: This is another example as to why I feel frequent flyer clubs and the free flight vouchers airlines hand-out are about as useful for transportation as a bananna peel. At a minimum, one should not attempt to use these things unless they are prepared to pay a "walk-up" fare to their destination.

Frequent flyer clubs MAY make some sense if one wants to accumulate hotel "miles," in a "frequent stay" program. Even then you open yourself to the possibility of an airline screeming "fraud," taking your account down to a negative balance; then saying you owe them for the allegedly improperly obtained miles. I could easily see United Air pulling a stunt like this.
