Don't complain about jetlag to English model and actress Poppy Delevingne. "Jetlag is for sissies," she said. "Get over it."

If anyone knows, it's her. The British model and actress spends a lot of time in the air these days, flying around the globe for both work (she has her first big acting role in Guy Ritchie's upcoming film “Knights of the Roundtable: King Arthur” and an ongoing collaboration of chic suits and beachy dresses with Solid & Striped) and play. Here, Delevingne explains when it's appropriate to travel in an animal onesie and what to steal off an airplane during your next trip.

Favorite airport lounge or restaurant?Terminal 5 in Heathrow. That place is dangerous. I once missed a flight because I got stuck in Prada.

Best or worst person you have ever been seated next to on a plane?Grace Jones was once on a plane with me. I just wish she’d brought her hula hoop.

Best freebie you've stolen off a plane?A captain’s badge. I was only five years old.

What’s the greatest travel advice you have ever received?Jetlag is for sissies. Get over it.

Airline with the best or worst food?Virgin has the best food for sure. I go bonkers when they bring the scones and jam out…

Is plane your favorite mode of travel? Or, what’s your preferred transportation method?Canoe.

Go-to travel outfit?Frame Denim boyfriend jeans, James Perse T-shirt, Balmain blazer, and a Bamford scarf and cashmere socks. On some occasions, an animal onesie.

Most luxurious hotel bathroom you've ever seen?My new one in London is pretty mega. The loo has my name and address on it. (It’s not a joke.)
