Yes, in 2026, suitcase size limits almost always include the wheels and handles. Airlines measure the "total exterior dimensions" of the bag. This is a critical detail because a bag labeled as "22 inches" by a manufacturer might only refer to the packing compartment, but once you add the height of the 360-degree spinner wheels and the retracted handle, it could measure 24 inches, potentially triggering a "gate-check" fee. Most major U.S. carriers like Delta and United have a standard carry-on limit of 22 x 14 x 9 inches, and they provide "sizer" boxes at the gate to verify compliance. If any part of the wheels or handle protrudes beyond those dimensions, the bag is technically oversized. To avoid issues in 2026, it is best to purchase luggage specifically marketed as "Global Carry-On" and to measure it yourself at home from the very bottom of the wheels to the highest point of the collapsed handle.
