A New Jersey man marked his 24 millionth mile on United Airlines on a flight from Newark to San Francisco.

Tom Stuker is the world’s most traveled air passenger. He has taken more than 12,000 flights and visited more than 100 countries.

Stuker purchased a “Lifetime Companion Pass” with United Airlines in 1990. The pass, which the airline no longer offers, allows him and another person to fly first-class around the world for life.

"It's been such a fun journey. I mean my Top 5 friends are from all over the world - different countries. My wife and I met around 5 million miles in Hawaii,” Stucker says.

Friends came in from all over the country to celebrate Stucker’s 24 millionth mile – some of whom met him in person for the very first time.

"We're in the same Facebook group of people who fly United Airlines a lot and he's there helping people out, and just kind of being a warm generous person and an interesting flyer and I don't think you can get more interesting than 24 million miles," says Dorothy Zemach, of Oregon.

Stuker says he does not plan to stop flying any time soon and hopes to make 25 million miles within the next few years.
