The quick verdict
The Samsonite Ziplite 4 Spinner Underseater is the bag I bought to stop checking luggage. It is small enough to fit under the seat in front of you, which means it counts as a personal item on many airlines, and if it ever does not, it drops into the overhead bin without a fight. Inside, it swallows a 15 inch laptop, a tablet and several days of clothes in a 5.3 pound polycarbonate shell with a built-in USB charging port. If you want to travel light and never pay a checked bag fee again, this is how.

Size: personal item first, carry-on insurance second
External dimensions are 18.2 by 13.9 by 8 inches, and internal dimensions are 15.5 by 13.3 by 7.2 inches. That is small enough to work as a personal item or underseat bag on every airline I checked, but personal item sizes vary from airline to airline, so check your airline’s specifics before you fly. The point of the size is insurance: even if an airline’s personal item limit is tighter, this bag fits the overhead compartment easily, so you are never the person forced to gate-check a bag.
I bought it because I do not want to check a bag. Checking is expensive, it makes the whole trip take longer, and I hate boarding with a carry-on only to find there is no bin space left. This bag ends all three problems, and as a bonus, travelling with less makes you minimise what you pack and only bring the essentials, instead of five shirts when you will wear two.
Build: polycarbonate, spinners and a USB port
The Ziplite 4 shell is 100 percent polycarbonate with a mesh texture on the outside, which gives excellent scratch resistance while staying strong and light at 5.3 pounds. Mine is a deep, rich blue; black and other colours are available too. Four multi-directional spinner wheels roll easily over pavement, smooth floors and airport terminals, there is a built-in carry handle on top, and the locking trolley handle extends to two heights and sits comfortably in the hand.
One of my favourite features is on the side of the bag: a rubberised cover hides a standard USB port. Put a power bank in the dedicated space inside the bag, and you can charge your phone directly from the port without fumbling around with an external battery and cables in the terminal. The zippers run all the way down so the bag opens flat like a hinge. There is no built-in TSA lock, but the zippers have lock points, so you can add your own lock if you want one. Samsonite backs it with a 10-year limited warranty.
Inside: a removable laptop sleeve and real organisation
Open it flat and the top section has a big mesh pocket that keeps things in place and organised. The bottom section holds the feature that sold me: a removable sleeve, clipped and velcroed in place, that fits a full 15 inch laptop as well as a tablet. You do not need a separate laptop bag. Below that is the main storage area for clothes and everything else.
To give you a sense of capacity, my test pack fit two pairs of pants, a pair of shorts, a couple of shirts, a couple of pairs of socks, a toiletry bag, a full-size 15 inch laptop and a sleep mask, comfortably, and I know I could fit more on a longer trip. It is not expandable and there are no exterior pockets, so what you see is what you get. Pack a pair of work boots, though, and this is the wrong bag: wear those on the plane.

FAQ
Does the Samsonite Ziplite 4 Underseater fit under an airplane seat?
Yes, that is what it is designed for, at 18.2 by 13.9 by 8 inches. Personal item allowances vary by airline, so confirm your carrier’s limits, and note it also fits easily in the overhead bin.
Can it hold a 15 inch laptop?
Yes. The removable interior sleeve fits a 15 inch laptop and a tablet, and clips securely into the case.
Does the USB port include a battery?
No. The port connects to your own power bank, which sits in a dedicated space inside the bag. The bag provides the convenient outside connection point.
Final verdict
The Samsonite Ziplite 4 Spinner Underseater is the smallest luggage I would actually travel with, and that is the compliment. It keeps your laptop, your clothes and your charging sorted, it never needs to be checked, and it removes the two worst parts of flying with a carry-on: the fees and the overhead bin lottery. For short trips and light packers, ditch the big carry-on.
