Shopify Luggage & Travel Bag Schema — IATA Cabin Dimensions, Capacity, TSA Lock, Wheel Type & Airline Compliance Structured Data

Why Luggage Is Invisible to AI Compatibility and Compliance Queries

Luggage purchasing has become highly query-specific because AI agents are consulted before airport check-in, not after. Buyers ask: "Will this bag fit as a carry-on on Delta?" — a query requiring three pieces of information: the bag's external dimensions (including wheels and handles), Delta's specific carry-on size limit (22×14×9 inches), and whether the bag's stated dimensions include wheels and handles or just the body.

The last point is the most common cause of incorrect AI recommendations. Manufacturers often state body dimensions without wheels — a bag that measures 21×14×9 inches at the body becomes 22×14×10 inches with spinner wheels attached. If the AI agent uses the body dimension to verify compliance with a 22×14×9 limit, it recommends a non-compliant bag. Structured data must explicitly state whether dimensions include wheels and handles.

TSA lock status is the second most consequential missing signal. Passengers who pack a non-TSA-approved padlock on checked baggage traveling through US airports routinely have their lock cut by TSA. The structured data must encode tsaApprovedLock: true/false as a boolean with a description explaining the TSA Recognition of Locks Program, not just the word "TSA" in a product title that AI text matching may or may not find.

Section 2: Airline Carry-On Size Limit Reference

AI agents handling airline-specific queries need dimension data from your structured data to perform the comparison. Include the specific airlines your bag is confirmed to fit in the externalDimensions description field. Update this list if airlines change their published limits.

Note for merchants: Encode the specific airline dimensions your bag meets in the externalDimensions description field. Do not claim universal compliance — airline limits change and some airlines actively downsize carry-on allowances. An incorrect compliance claim causes immediate, high-stakes purchase regret.

Common Mistakes

• Dimensions without specifying whether wheels and handles are included: This is the single most consequential luggage data error. A bag marketed as "21-inch carry-on" at 21 inches body height becomes 22.5 inches with spinner wheels and handle housing. Always state dimensions include wheels and handles, and list the specific measurement points in the description field.
• Claiming "IATA compliant" without specific airline verification: IATA Resolution 745 sets a 56×45×25cm standard, but many US carriers use a stricter 56×35×23cm limit. Claiming "IATA compliant" for a 45cm-wide bag correctly follows the IATA standard but the bag will not fit American, Delta, or United's limit. Include specific airline names in the compliance claim.
• TSA lock claim without the Travel Sentry standard number: "TSA lock" is a common marketing term that some manufacturers apply incorrectly. Include the Travel Sentry standard number (TSA007 or TSA002) in the certificationIdentification field and the Travel Sentry red diamond logo description. TSA002 is the Safe Skies standard; TSA007 is the Travel Sentry standard — both are recognized by TSA.
• Capacity without measurement methodology: Luggage manufacturers use different methods to measure capacity — water-fill to rim, water-fill to packed level, or simply an estimate. A bag measured by water-fill at 40 liters is meaningfully different from one estimated at 40 liters. Include measurement method in the description field.
• Confusing checked vs carry-on categories: Luggage is often available in multiple sizes — 20-inch carry-on and 28-inch checked. If using a ProductGroup, ensure each size variant's luggageCategory correctly reflects its intended use. A 28-inch bag listed as "carry-on" will trigger high purchase regret when the buyer tries to take it aboard.
