Bag spec source: swissgear.com · accessed 2026-07-09. Airline limits come from each carrier's official baggage page; open an airline above for its citations. Policies change, so verify a borderline case before you fly.
Every SwissGear product page observed on swissgear.com lists two separate figures, INTERIOR DIMENSIONS and EXTERIOR DIMENSIONS, with an explicit footnote that the exterior number includes the wheels and handle. The interior figure is the packable cavity, not a wheel free shell measurement, so treat it as a packing volume reference rather than a true body only depth. No SwissGear page observed gave a body only shell measurement excluding wheels, so bodyOnly is left null throughout this file.
