Oh, you fly first class? That's cute.

But let us remind you that while you may feel like a boss with your extra leg room and seat on the other side of the curtain, there's a thoroughbred race horse who flies first-class on a custom Boeing 727 that's been transformed into the ultimate stable in the sky.

American Pharoah, an American thoroughbred who recently won the Kentucky Derby, travels for races in a lavish plane that is apparently the preferred transportation for elite race horses. But the best part? The plane is called Air Horse One.

The entire inside of the Boeing 727 was gutted and replaced with stable stalls and hay to resemble a barn, and is currently what the Kentucky Derby champion used to get to the second-leg of the Triple Crown in Baltimore.

A ride on Air Horse One isn't cheap, though. Airfare for the 50-minute flight on the custom plane, which fits 21 horses, starts at $3,500 with prices going up if more stall room is requested.

But sorry, human, you're not invited.
