Tom Stuker, 69 from New Jersey (@ua1flyer on Instagram), earned the impressive title by accumulating a staggering 23 million air miles throughout his life.
Having spent entire days travelling on planes, the self-proclaimed globetrotter claims to have cracked the code for getting the best seat, keeping luggage safe, and securing a range of in-flight freebies.
The US traveller had been working on his world-renowned status since 1990 when he purchased a lifetime pass with United Airlines for $290,000 (£227,516.60).
Since then, Tom has travelled in seat 1B on almost every flight as he reaped the benefits of his unlimited first-class travel pass.
Now somewhat of an expert at travelling by plane, the father-of-two has shared his wisdom with other passengers heading overseas.
