Bag spec source: travelpro.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 Travelpro product page checked in this pass published two separate structured spec fields, Case Dimensions (the bag body alone) and Overall Dimensions (explicitly labeled on most pages as including wheels and carry handles), both in inches with weight in pounds; no centimeter figures were published on any fetched page. The gap between the two ranges from about 1 inch on softside Rollaboard styles up to 3.25 inches on the hardside Maxlite Air V2 and Platinum Elite Hardside carry-ons, so the body number alone understates real gate sizer footprint by a meaningful margin on this brand.
