55×37×23 cm Cabin Luggage – Optimized for Network Airlines
Many full-service airlines allow slightly deeper cabin luggage, typically around 55×40×23 cm. Openwater’s Cabin Plus 55×37×23 cm format is designed to stay within this broader category while keeping the suitcase balanced and easy to maneuver.
Airlines that commonly allow cabin bags up to 55×40×23 cm include:
Scandinavian Airlines (SAS)
Lufthansa
Brussels Airlines
Norwegian
Finnair
Swiss
Turkish Airlines
These airlines usually allow one cabin bag plus a personal item such as a laptop bag or handbag. Because of the extra 3 cm of depth, luggage in this category offers slightly more packing volume, making it ideal for longer trips or business travel
