Technically you don't have to be in an airplane to achieve this. Just go into the bathroom at a Denver Broncos home game and sex it up.

To have intercourse while piloting an aircraft. The altitude must 5,280 feet MSL not AGL. In other words, one cannot park on Denver Airport property, bang each other, and earn their wings to the Mile High Club.

Indulging in any form of sexual intercourse in an in-flight Airplane restroom, while, obviously, being at least a mile off the ground.
"I hope the flight attendant didn't see us come in here...she might know we're becoming members of the Mile High Club."
