Checked Luggage

Start with the rules for the airline and route you actually fly, then leave a useful weight margin for the contents. IATA says checked allowances vary by airline and route; it notes 23 kg (50 lb) as a common guideline and 158 cm (62 in) in combined length, width, and height as a common maximum where the piece system applies. Measure the case with wheels and handles included, and do not treat those figures as universal.

Focus on the load paths rather than the finish: wheel housings, axle mounts, telescoping-handle anchors, carry handles, zipper corners or latches, hinges, feet, and shell corners. Move every wheel under light load, extend and twist the handle gently, and inspect fasteners from inside where possible. IATA maintains baggage-construction recommended practices, so a seller's vague “airline tested” claim is less useful than a disclosed test method and clearly serviceable components.

Use durable external identification that does not expose more personal information than necessary, and place a second contact card inside in case the outer tag disappears. Keep the airline's bag-tag receipt until the case is returned. IATA specifically encourages identification both outside and inside checked baggage, while Resolution 753 calls for member airlines to record bags at a minimum of four core tracking points; a personal tracker can supplement, but not replace, the airline record.

Treat the battery as a safety constraint, not a convenience feature. The FAA says spare lithium batteries, power banks, electronic cigarettes, and vaping devices are prohibited in checked baggage and must remain accessible in the cabin. Devices containing lithium batteries should preferably stay in carry-on baggage; if a permitted device is checked, it must be completely off, protected from activation and physical damage, and comply with the airline's restrictions. Confirm that any smart-case battery is removable before buying.

Look for replaceable wheels, feet, handles, zipper pulls or latches, ordinary fasteners, and interior access to the mounting points. Before purchase, verify that parts can be ordered in the United States, that repair instructions or service centers exist, and that the warranty explains exclusions, shipping costs, and who performs the work. IATA's baggage standards include a specific recommended practice for baggage construction, but durability claims still need product-level evidence and a realistic parts path.

Keep valuable or irreplaceable items out of checked baggage; IATA explicitly advises against placing them there. Also move spare lithium batteries, power banks, e-cigarettes, and vaping devices to accessible carry-on baggage, as the FAA prohibits those items in checked bags. Review the airline's rules and the relevant safety restrictions before each trip, because acceptance can depend on the item, battery size, route, and carrier.
