There are a million lists of ‘travel hacks’ out there and I almost never share them, but for some reason I figured I’d pass this one along. It’s a list of 45 tips, some of which will be new to even the most seasoned traveler.

A few of them I already do, like roll clothes in a suitcase rather than fold and pack them. Another one is to bring food on board, especially if you’re flying economy. I’ve opted for a Subway sandwich from Vancouver airport many times before boarding, and my fellow passengers usually give me longing looks as I unwrap it while they dig into their soggy broccoli.

One of these tips genuinely surprised me, though: frozen items are permitted through security. We’ve all been caught, usually accidentally, with a water bottle in our carry-on luggage while passing through security. People either chug the water like it’s a high school beer, or just pass it to the security agents. However, if that same bottle of water was frozen, you’d get through with no trouble at all. Who knew?

If you’d like to pick up a few more ideas, or just miss traveling and want to pretend like you have a trip coming up, then dig in.
