Should I buy a carry-on or checked suitcase for a 2-week international trip?

Buy a 21-22 inch carry-on. You can pack for 2 weeks using packing cubes and doing laundry once mid-trip. Checked bags add fees (50-100 dollars round trip on budget airlines), risk loss, and slow you down at arrival. Only buy checked if you need specialized gear (ski equipment, diving gear) or are moving abroad.

What size suitcase is allowed on international flights?

Most international airlines allow 22 x 14 x 9 inches (56 x 36 x 23 cm) as carry-on, but budget carriers in Europe and Asia enforce stricter limits—often 21 x 13 x 9 inches (55 x 35 x 20 cm). Always check your specific airline before departure. If in doubt, buy a 21-inch suitcase to stay under all limits.

Are hard-shell or soft-sided suitcases better for international travel?

Hard-shell is better for 90% of international travelers. It protects contents during rough baggage handling, resists rain and dirt, and survives cobblestone streets. Soft-sided is only better if you need to squeeze the bag into tight overhead bins on small regional planes or want external pockets for documents and snacks.

How much should I spend on a suitcase for international travel?

Spend 100-150 dollars on a mid-range hard-shell spinner (Samsonite, American Tourister). It will last 5-10 international trips. Budget bags under 60 dollars break after 1-2 trips. Premium bags (Away, Rimowa) at 250-600 dollars are worth it only if you travel internationally 4+ times per year or want a lifetime warranty.

Do I need a TSA-approved lock for international travel?

Yes, if transiting through or departing from the US. TSA-approved locks let security open your bag without breaking it. For travel entirely outside the US, TSA locks still work but are not required—regular combination locks are fine. Never use key locks; you will lose the key.

Can I bring a suitcase with a built-in battery or charger on international flights?

Most airlines ban or restrict suitcases with non-removable lithium batteries. If the battery is removable, you must remove it and carry it in your personal item. Avoid smart luggage with built-in chargers—buy a separate power bank instead.

How to Choose a Suitcase for International Travel

Choose a hard-shell carry-on spinner (21-22 inches) with TSA-approved locks and four double wheels for most international trips. Budget travelers flying checked-bag airlines can opt for a larger 28-inch checked suitcase. Avoid soft-sided bags for international travel unless you need maximum packability for multi-country backpacking.

Decide carry-on vs checked based on your airline and trip length. If flying budget carriers in Europe or Asia (Ryanair, EasyJet, AirAsia), you need a true carry-on that fits their smaller limits: usually 21-22 inches (55cm) and under 17 pounds. If flying full-service airlines with free checked bags (many international carriers), a 28-inch checked bag works for 2+ week trips. For 1-2 week trips on any airline, a 21-22 inch carry-on forces efficient packing and saves baggage fees.
Choose hard-shell over soft-sided for international durability. Hard-shell polycarbonate or polypropylene suitcases survive international baggage handling better than soft-sided nylon. They protect fragile items, resist rain, and are easier to clean after dusty or dirty transport. Soft-sided bags are only better if you need to compress the bag to fit tight spaces (like European hotel storage) or want external pockets for quick-access items.
Get four spinner wheels, not two inline wheels. Four double spinner wheels (8 wheels total) let you push the bag in any direction and navigate crowded airports, train stations, and cobblestone streets without strain. Two inline wheels (roller bags) require you to tilt and drag, which wears you out over long distances. Spinners are worth the slightly reduced internal packing space.
Verify the suitcase meets international carry-on size limits. Maximum carry-on is usually 22 x 14 x 9 inches (56 x 36 x 23 cm), but budget airlines enforce stricter limits. Measure with wheels and handles included—many bags are sold as 'carry-on' but exceed actual limits. If your bag is 23 inches, you will gate-check it and pay fees. Buy 21 inches to be safe across all airlines.
Look for TSA-approved locks and YKK zippers. TSA-approved combination locks let US and some international security open your bag without breaking it. YKK zippers are the most durable and least likely to fail mid-trip. Check that the zippers have lockable dual pulls so you can secure them together.
Test the handle extension and weight when empty. Extend the telescoping handle fully—it should lock at a comfortable height for your build and not wobble. Weigh the empty suitcase. Hard-shell carry-ons should weigh 6-8 pounds empty. If it weighs 10+ pounds empty, you lose packing capacity to airline weight limits (usually 15-22 pounds for budget carriers).
Skip built-in chargers, GPS trackers, and other gimmicks. Suitcases with built-in batteries or electronics are banned or restricted on many international flights. GPS trackers fail without cell service. Buy a simple, durable suitcase and add an AirTag or Tile tracker separately if you want tracking.
