What is the weight limit for luggage on airplanes

Pack checked bags to 23 kg (50 lb) when flying international on most carriers; expect 32 kg (70 lb) allowance on premium cabins and business fares.

IATA recommendation of 23 kg (50 lb) remains industry standard in economy class checked items; many European and Asian airlines follow that practice, while North American carriers often price checked pieces per piece with 23 kg common soft cap. Maximum linear dimension usually set at 158 cm (62 in) as sum of length+width+height.

Cabin bag rules vary: common mass allowances range 7–10 kg on low-cost European operators; Ryanair and Wizz Air typically state 10 kg on larger cabin items with strict size requirements. Major US airlines tend to regulate size rather than mass, permitting one cabin bag plus one personal item provided measurements fit overhead bins or under-seat space.

Practical steps: weigh each piece at home using a handheld scale; move dense items into checked pieces or onto bodywear; check size and mass allowances shown on booking confirmation; prepay extra allowance online when possible to save on counter surcharges. At gate, expect random checks and potential gate-checking or overweight surcharges when allowances are exceeded.

Carry-on allowances: major carriers vs low-cost operators

Keep cabin bag under 7 kg when flying with many Middle Eastern and Asian full-service carriers; aim below 10 kg when using European low-cost operators unless priority added.

US legacy carriers (American, Delta, United) usually publish size requirements rather than mass caps; gate agents rarely weigh cabin items, but oversized pieces may be gate-checked.

Major international full-service names such as Emirates, Qatar Airways, Etihad commonly list a 7 kg cabin allowance in economy; business and first often permit either a second bag or a higher combined mass.

European legacy carriers (British Airways, Lufthansa, Air France, KLM) vary by route and fare. Some publish explicit mass caps near 8–12 kg on short and medium haul flights; others rely on size alone on long-haul sectors.

Low-cost operators enforce stricter rules: Ryanair and Wizz Air normally allow only a small personal item free (approx 40 × 20 × 25 cm); paid priority usually expands allowance to a 55 × 40 × 20–23 cm bag with a 10 kg cap.

easyJet, Vueling and similar carriers frequently sell cabin allowance as an add-on; expect 7–10 kg or a size-only policy depending on booking option. Spirit and Frontier monetize carry-on access heavily; standard fares often exclude cabin bags, paid options commonly include a 40 lb (18 kg) cap.

Practical steps: weigh cabin bag at home using a digital scale, move dense items into checked piece when possible, buy priority or prebook cabin allowance online to avoid higher gate charges, carry vital items in a personal item that fits under seat, and confirm exact dimensions plus max mass via airline website 24–48 hours prior to departure.

Checked-bag mass thresholds, typical fees, airlines’ weighing methods

Recommendation: keep each checked bag at or below 23 kg (50 lb) on most economy tickets; aim under 20 kg (44 lb) when flying with low-cost carriers selling per-kilo allowances.

Common thresholds: many full-service international carriers apply a 23 kg (50 lb) allowance per piece in economy and 32 kg (70 lb) per piece in business/first; per-piece system often limits quantity to one or two pieces depending on fare class; low-cost operators typically sell allowances in 10–32 kg increments or fixed-piece options such as 1×20 kg or 2×23 kg.

Typical fees: US domestic carriers set first checked bag fees at roughly $30–$35 and second-bag fees at about $40–$45 when purchased online prior to arrival; excess-mass charges commonly run about $100 between 23.1–32 kg (51–70 lb) and around $200 above 32 kg (70 lb); oversized linear-dimension charges (baggage exceeding 158 cm / 62 in) often add $75–$200 depending on carrier and route; low-cost carriers set bag charges by route and purchase moment with prepaid online rates frequently 20–60% lower than counter prices.

Weighing and enforcement methods

Scales at check-in counters and curbside represent carrier’s official measurement; gate checks may occur when cabin space or balance issues arise; staff commonly record mass in kilograms then convert to pounds, which can introduce rounding that affects fee assessment; some airlines apply random secondary checks near jetway.

Practical steps: use a calibrated digital bag scale at home and label each bag with actual mass; redistribute items between bags to avoid excess-mass penalties; prepay excess mass online when available since online fees often beat airport rates; measure linear dimensions and compare against 158 cm (62 in) common maximum to avoid oversized surcharges.

How to weigh and measure your bag at home to avoid gate surprises

Aim to keep packed mass at least 1.5–2 kg (3.3–4.4 lb) below carrier allowance; verify mass using two independent methods: hanging scale and bathroom-scale subtraction.

Accurate mass checks

Hanging-scale method: attach scale strap to handle, lift straight up until display stabilizes, record reading. Calibration note: test scale with known object (2 kg dumbbell or water bottles). Accuracy expectation: ±0.1 kg on decent models. If reading nears allowance, remove heavy items then recheck.

Bathroom-scale subtraction: step onto scale, record personal mass. Hold packed bag, step onto scale again, record combined mass. Subtract personal mass from combined mass to obtain bag mass. Stand centered on scale, use same footwear each time, repeat measurement 2–3 times and average results.

Dimensions and packing tweaks

Use tape measure to record length, width, depth. Measure along longest axis; label that measurement length. Compute linear total as length + width + depth; common checked-item benchmark equals 158 cm (62 in). Calculate girth as length + 2×(width + depth) when carrier policy references girth plus length.

Packing adjustments: move dense objects near wheel end to improve balance; swap heavy shoes into worn outfit; transfer liquids into travel-size containers and place inside sealed pouch; use vacuum-compression bags to reduce volume while monitoring added mass of extra layers. Aim to split heavy contents across multiple bags so each stays within carrier allowance margin.

Home tools checklist: portable hanging scale, adhesive tape measure, small postal scale to weigh electronics, spare batteries, permanent marker to note measurements inside tag. Calibrate scales periodically by weighing known masses and replace batteries when display dims.

Actions if your bag exceeds airline allowance: repack, redistribute, pay, ship

Immediate recommendation: perform on-the-spot repack and redistribution first; if excess mass remains, prepay extra allowance online or arrange courier shipment before check-in closes.

1. Repack – fast tactical steps:

   • Remove dense items (shoes, books, camera batteries) and place into cabin bag or personal item.
   • Wear bulky clothing (jacket, boots) during transit to cut mass on checked piece.
   • Use compression bags for soft garments to gain 10–30% extra volume.
   • Move toiletries with liquids into cabin item if they meet carry-on restrictions; pack only travel sizes in checked piece.
   • Place small electronics, chargers, documents into carry-on; heavy metal items into shoes or internal pockets to even distribution.

2. Redistribute – teamwork and smart splitting:

   • Ask travel companion to take one heavy item into their checked allowance if they have spare capacity.
   • Split contents across two checked pieces when a second bag has been prepaid; typical domestic extra-bag fee runs $30–$60, often cheaper online than at counter.
   • Consolidate items so each bag stays under common airline thresholds (common thresholds: 23 kg / 50 lb and 32 kg / 70 lb). Airlines often charge incremental fees: moderate excess ~US$75–$200; extreme excess or >32 kg/70 lb ~US$200–$400 or refusal, depending on carrier.

3. Pay – cheapest choices and timing:

   • Check airline app or website to buy extra allowance before airport arrival; online prepayment frequently saves 20–50% compared with counter rates.
   • If over by small amount (under ~3–5 kg), cheap add-ons or upgraded cabin class may cost less than shipping; compare instant online prices versus courier quotes.
   • At airport kiosks and desks, expect higher fees and possible surcharge for card use; have cash ready where accepted by carrier.
   • Keep receipts and booking reference when paying; some credit cards include travel protections that may reimburse excess-baggage charges under specific conditions.

4. Ship – when paying carrier fees becomes uneconomic:

   • Domestic courier options: ground service often costs US$20–US$80 per medium box within same country, transit 2–7 days; overnight ranges US$50–US$200 depending on distance and size.
   • International door-to-door: expect US$60–US$300+ depending on weight, dimensions, customs formalities; choose economy surface shipping for bulky non-urgent items to lower price.
   • Use tracked, insured service for valuables; declare accurate mass and dimensions to avoid surprise charges at pickup.
   • At many airports, on-site cargo offices handle excess oversized pieces; compare airport cargo rates with local courier quotes before handing over.

Quick decision guide (use measured excess in kg to choose action):

• Up to 3–5 kg over: repack + redistribute into cabin item or companion’s bag.
• 5–15 kg over: prepay extra bag online or split into second checked piece if allowed; compare with courier price.
• More than 15–20 kg over or bulky/odd-shaped item: ship via courier or airport cargo; expect higher fees and longer transit.

Final checks before handoff: photograph contents, remove valuables, lock bag with TSA-accepted lock when applicable, keep shipping/tracking information accessible, and confirm estimated arrival time to avoid missed connections.

International differences in mass allowances: US, EU, Asia-Pacific and budget carriers

Prepay hold allowance online at least 24 hours before departure to save up to 70% compared with airport fees.

US carriers: Most legacy US operators publish a 50 lb (23 kg) per-checked-piece standard on many domestic and international economy fares. Usual domestic fees: USD 30 for first checked piece, USD 40 for second. Excess-mass surcharges typically USD 50–100 for 51–70 lb (23–32 kg) and USD 100–200 for above 70 lb (>32 kg); some carriers refuse overly heavy pieces or require special cargo handling.

EU carriers: Full-service European carriers generally follow 23 kg (50 lb) / 32 kg (70 lb) tiers similar to IATA guidance on long-haul routes, while short-haul low-fare operators often sell hold space separately or allow only a small personal item free. Typical intra-Europe paid checked-piece fees range EUR 15–60 online, EUR 30–80 at airport. Piece-versus-kg model varies by carrier, so check itinerary by segment.

Asia-Pacific carriers: Mixed approaches. Japanese majors and several Asian carriers apply piece concept (common allowance: one 23 kg piece in economy on long-haul; two 23 kg pieces in premium cabins). South‑East Asian low-cost carriers use kg-based bundles (common bundles: 20 kg, 25 kg, 40 kg) sold online at discounted rates. Australian operators often mirror European tiers (23/32 kg), while Middle Eastern and some premium Asian carriers allow larger per-piece caps (30–32 kg) for premium cabins.

Budget carriers: Pay-per-item model. Typical free cabin allowance limited to personal item only (around 7–10 kg); larger cabin bags require paid priority or specific fare. Hold bundles commonly sold in fixed sizes (10 kg, 15 kg, 20 kg, 25 kg, 30 kg). At-airport purchase and excess-mass rates are steep (common airport penalty rates 3–10 times online bundle unit price), so prepay always cheaper. Examples: Ryanair offers 10 kg/20 kg hold bundles; EasyJet sells hold space with cabin caps up to 15 kg on some fares; AirAsia offers 20 kg and 40 kg bundles with online discounts.

Practical regional tips: always convert units (kg ↔ lb) before booking; verify piece-versus-kg policy per ticketed carrier on each segment; check codeshare operator policy when itinerary includes partner-operated legs; use alliance status or premium fares to secure higher per-piece caps; compare prepay online fee versus airport surcharge and excess-mass per-kg rates; for oversized or very heavy items, compare excess charges with door-to-door courier quotes on international routes.

FAQ:

What are the typical weight limits for checked luggage on airplanes?

Airlines use two common systems: a piece-based allowance (a fixed number of bags, each with a maximum weight) and a weight-based allowance (a total kilogram allowance across all bags). For economy passengers on many major carriers a single checked bag is often limited to about 20–23 kg (44–50 lb). Premium cabins frequently allow heavier bags, commonly up to 30–32 kg (66–70 lb) per piece. Low-cost carriers may set lower limits or charge per kilogram and some international routes apply different rules. Exceeding the standard weight usually triggers an extra charge or a requirement to redistribute or reduce weight. Always check the specific carrier’s policy for your ticket class and route before packing.

How heavy can carry-on luggage be and what size rules apply?

Size rules are the primary restriction for hand luggage on many airlines (for example, around 55 × 40 × 20 cm or 22 × 14 × 9 in is common), and some carriers enforce strict weight limits while others rarely weigh carry-ons at the gate. Low-cost airlines frequently limit cabin bags to 7–10 kg (15–22 lb); legacy carriers may allow heavier carry-ons but expect a small personal item plus one cabin bag. If a hand bag is too large or heavy at boarding, it can be gate-checked and fees may apply.

What happens if my bag is overweight and what practical steps can I take to avoid high fees?

If a checked bag exceeds the allowed weight, the airline will typically charge an overweight fee, require payment for an extra piece, or ask that you remove items until the bag meets limits. Fees are usually higher at the airport than those purchased online in advance. Practical ways to avoid charges: weigh luggage at home with a portable scale, move heavy items into carry-on or a personal item (within cabin limits), redistribute contents across multiple checked bags if your fare allows more than one piece, wear heavy clothing at boarding, or ship bulky or heavy items via parcel service ahead of travel. For very heavy items (often over ~32 kg / 70 lb) some carriers will refuse carriage for safety reasons or require a special cargo arrangement. Also check sports-equipment and musical-instrument rules in advance, as those items may need separate booking and fees.
