The first step to One Bag Travel is to find your airlines’ dimensions. This will determine how big your carry on can be. Don’t see your airline in the list below? Let me know in the comments and I’ll add it. I’ve listed smaller item dimensions separately in the Personal Item Luggage Dimensions Table.
Once you know your dimensions, you need a travel backpack. There are a TON of options, but don’t worry. I will help you decide which pack is best for you.
If you don’t know where to start, try my Epic post of All the One Bag Travel Backpacks. It’s a huge post, outlining most of the travel backpacks on the market. The perfect bag for you is probably in here somewhere. If you’re looking for a quick guide on backpack dimensions, check out this Travel Backpack Size Table.
Then search my site for more info on your perfect bag. This is the ongoing list of all the backpacks I’ve personally tested and reviewed. There are some great bags in here, let me show you which bags I’ve tried and like.
