One must wonder if any FTers have begun booking all travel for family and friends since getting a Travel Club account, as booking a ticket for anyone gets you the $5 credit. Luckily my girlfriend does not pay much attention to OnePass or its offers (or anything else mileage-related...but she rather enjoys the upgrades, so tolerates my affliction), so I've been booking all of her paid travel lately. She doesn't even ask why...just provides her credit card details and is just glad to have someone else do all the work. Have a friend who travels infrequently on CO who I've managed to book some travel for as well.
I wouldn't doubt some FT'er with a Travel Club account is out there pushing his de-facto travel agency on family & friends who aren't in the know for $5 credits
