Start with the rule
The airline limit outranks every feature.
Cabin compatibility depends on the airline, fare, route, and whether handles and wheels are included. Check the current allowance for the flight you are actually booking before comparing materials or wheels.
The six checks that matter
- 01
External size
Use the full measured dimensions, including wheels and handles.
- 02
Empty weight
Every kilogram in the case is one less kilogram available for packing.
- 03
Usable volume
Treat capacity as directional because brand measurement methods can differ.
- 04
Expansion
Useful for road or rail legs, but often risky under a strict cabin rule.
- 05
Organization
Choose compression and pockets that match how you actually pack.
- 06
Warranty and repair
Read what is covered, excluded, and required to make a claim.
