I’m a software engineer with one of the really big software companies. I fly about 80,000 miles a year, mostly throughout the US and Canada but I get a trip or two to Europe each year too.

My niece has a degree in Travel & Tourism and got a position in corporate sales with a major travel agency. She WON a flight to Paris on the Concorde while that was still flying.

Or become a tour booking agent and go along on them.

Here in Las Vegas, they encourage people to go into the Airline industry or become travel agents. There are some business sales jobs that need you to travel overseas.
good luck with your choices and future.
