One cubic foot. That’s roughly how much volume airlines grant you for the 9 inch x 10 inch x 17 inch “personal item” that goes under your seat. It’s a tiny allowance. Sure, you have a bit more space in your bag stored in the overhead bin. But nowadays many airlines are charging you for overhead bin access (THANKS, basic economy). Even if they don’t, nobody wants to be that guy who gets up every hour to get things from the overhead bin — especially if you’re sitting in the window seat.

So if you fly frequently, you put a lot of thought into what goes into your under-the-seat-in-front-of-you storage. The contents of your inflight go-bag are probably a good window into your personality and priorities when it comes to flying. In the spirit of sharing, I’ve compiled a list of the five essential things that I always have in my carry-on bag. Some cover the basics necessities, some are for fun, and some are for the AvGeek in me. And once you’re done reading my list, let’s hear what’s on yours!

So little space. So much potential!
