When you own an airline, as Skuli Mogensen, founder and owner of WOW Air does, chances are, you are going to spend a lot of time in the air. It makes sense then that, in an interview with The New York Times, Mogensen has a few tips for packing. 

What is the one thing that he doesn’t leave home without? A carry-on. 

“I’m a master packer,” he tells The New York Times. “I will always take just a carry-on. To be efficient, you do not want to have lost luggage. I’m running an airline and, unfortunately, these things happen. I try to travel as light as possible.”

He also always brings sports gear.

“I bring running shoes and one set of gym clothes. It’s extremely important when you sit on a plane a lot just to go out and get some fresh air during your travels. It’s the best way to counter jet lag and travel tiredness,” he tells The Times. 

Surprisingly, Mogensen doesn’t bring his laptop. 

“I used to travel with my computer all the time. Now an iPhone or iPad is more than enough unless I’m going to do some heavy work on the plane. Anyway, you can reduce weight and hassle and keep it simple, I think that’s a good thing,” he tells The Times.
