Bag spec source: us.delsey.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.
Delsey's US site (us.delsey.com) states all dimensions natively in inches; no cm figures were seen on any US product page fetched for this dataset. Most product pages publish one 'Exterior dimensions (includes wheels and handles)' figure alongside a smaller 'Interior dimensions' figure for packing capacity, and do not separately publish a wheels-and-handles-excluded body size, so the exterior figure is the overall, gate-relevant measurement and bodyOnly is null for every entry here.
