Welcome to FlyerTalk, blr1222!^

There are several threads here with similar questions and lots of answers. Here are just a few, to give you an idea of the careers of many FlyerTalkers:
What jobs do all you Frequent Travellers have?
High Travel Jobs (Give It A Chance, Please!)

Beyond that, I think you'll find that many frequent flyers here don't even fly for work. Speaking for myself, I fly well over 250,000 miles/year for leisure.
