I am a fussy traveler. It takes me ages to optimize flight routes, booking codes, layovers, seat selection and more. One thing that has helped is having good carry on luggage, so I don't have to deal with baggage claim. I wanted a spinner style hard shell carry on, that I would be able to take around the world. I ideally wanted two more features though. Expandability, to be able to squeeze in a bit more or to come home with gifts. And then a front pocket, just big enough for laptop, headphones, charger, passport, etc. Turns out its difficult to get all these features together, In fact I could only find 1-2 products that met all of my requirements. I searched for hours, so I thought I'd share the data that I discovered,. so you don't have to.
