An airplane isn't the most romantic or convenient place to have sex; in fact, the biggest perk is probably being able to say you're a member of the exclusive, elusive mile-high club. Somewhat surprisingly, in the June issue of Cosmopolitan, Chrissy Teigen confessed that she and John Legend did the deed on a plane. "We were on our way to Thailand to see my parents, flying commercial first class," she said when asked about the craziest place she had sex. "We were under a blanket. We weren't even in one of those pod things. I feel like we should get a trophy for that." Those of us relegated to coach might have to opt for the airplane bathroom, and veterans advise choosing an occasion on an overnight or very long flight. How much do you have in common with Chrissy and John?
