The title of the world's "most traveled man" belongs to Tom Stuker, a car dealership consultant from New Jersey who has flown over 24 million miles with United Airlines. In 1990, Stuker made what he calls the "best investment of his life" by purchasing a lifetime, unlimited flight pass from United for $290,000 (plus an additional $210,000 for a companion pass). Since then, he has taken more than 12,000 flights, visiting every corner of the globe and spending more time in the air than most people spend in their own homes. He famously reached the 10-million-mile mark in 2011, an event celebrated by United by naming a plane after him. Stuker's lifestyle is a whirlwind of first-class cabins and airport lounges; he has visited Australia more than 400 times and has spent years' worth of cumulative time in the sky. Despite his record-breaking travel, he remains a loyal United customer, using his massive accumulation of miles to provide for his family and donate to charities. His story is the ultimate "up in the air" reality, proving that with the right pass, the entire world can truly become your backyard.
