Stowaway?

Apparently a dude was discovered as a stowaway on an American Airlines flight from Guatemala City to Miami. According to FlightAware, AA1182 is a thousand mile daily run, a roughly two and a half hour flight at 37,000 feet with a 737-800. The news says dude was in a main gear well, but how do you do that without dying of hypoxia?

According to an FAA report (PDF) from the 1990s, it's a fifty-fifty gamble at best.

I get claustrophobic in an aisle seat, so gear well steerage is right out as far as I'm concerned.
