Carry-On Weight Limits by Airline (2026 Guide)
Carry-on weight limits vary from 5 kg on Chinese carriers to no limit at all on US airlines. Here's how major airlines compare and how strictly they enforce it.
Carry-On Weight Limits by Airline (2026 Guide)
When it comes to carry-on bags, size gets most of the attention — but weight limits can catch travelers just as off-guard. A 7 kg limit sounds generous until your laptop, cables, shoes, and a few days of clothes push you to 9 or 10 kg. This guide breaks down exactly what each major airline allows and how strictly those limits are enforced.
Why Weight Limits Exist
Airlines impose carry-on weight limits primarily for safety and cabin crew workload. Heavy bags in overhead bins pose an injury risk when lifted, and aircraft weight-and-balance calculations account for cabin baggage. Some airlines also use weight limits as an ancillary revenue tool — if your bag is too heavy to bring aboard, you pay to check it.
Carry-On Weight Limits by Region
United States: No Weight Limit (for Most Carriers)
US full-service and low-cost airlines stand apart from the rest of the world: they generally do not impose carry-on weight limits at all.
| Airline | Weight Limit | Notes |
|---|---|---|
| American Airlines | None | Size limit only |
| Delta Air Lines | None | Size limit only |
| United Airlines | None | Size limit only |
| Southwest Airlines | None | Size limit only |
| JetBlue | None | Size limit only |
| Spirit Airlines | None | Size limit; personal item only on cheapest fares |
| Frontier Airlines | None | Size limit only |
The lack of weight limits means US domestic flyers can load their carry-on as heavily as they can physically manage — as long as it fits in the overhead bin.
Europe: 7–10 kg, Often Actively Enforced
European carriers are more varied. Full-service airlines like British Airways and Lufthansa allow 8–12 kg, while budget carriers typically cap at 7 or 10 kg and are more likely to enforce it.
| Airline | Weight Limit | Size Limit |
|---|---|---|
| Ryanair (Priority) | 10 kg | 55 × 40 × 20 cm |
| easyJet | No limit | 56 × 45 × 25 cm |
| Wizz Air | 10 kg | 55 × 40 × 23 cm |
| British Airways | 23 kg (combined) | 56 × 45 × 25 cm |
| Lufthansa | 8 kg | 55 × 40 × 23 cm |
| Air France | 12 kg | 55 × 35 × 25 cm |
| KLM | 12 kg | 55 × 35 × 25 cm |
| Norwegian | 10 kg | 55 × 40 × 23 cm |
| Vueling | 10 kg | 55 × 40 × 20 cm |
British Airways is unusual in applying a generous 23 kg combined limit across all cabin baggage, making it effectively unlimited for most travelers.
Asia-Pacific: Strictest Limits, Most Consistent Enforcement
Asian carriers tend to apply stricter weight limits and enforce them more consistently. Many weigh bags at check-in rather than at the gate.
| Airline | Weight Limit | Notes |
|---|---|---|
| Singapore Airlines | 7 kg | Per piece; enforced |
| Cathay Pacific | 7 kg | Economy; 15 kg business |
| Japan Airlines | 10 kg | |
| ANA | 10 kg | |
| Qantas | 7 kg | Economy; also size-checked |
| Air New Zealand | 7 kg | |
| Vietnam Airlines | 7 kg | |
| Air Asia | 7 kg | Strictly enforced |
| Scoot | 10 kg |
Chinese carriers are typically the strictest:
| Airline | Weight Limit |
|---|---|
| Air China | 5 kg |
| China Eastern | 5 kg |
| China Southern | 5 kg |
| Hainan Airlines | 5 kg |
A 5 kg limit is very strict — it means a laptop, chargers, and a change of clothes can be enough to hit the limit. Enforcement on Chinese carriers at Chinese airports is among the most consistent in the world.
Middle East: Moderate Limits, Generally Reasonable
| Airline | Weight Limit | Notes |
|---|---|---|
| Emirates | 7 kg (economy) | 10 kg (business) |
| Qatar Airways | 7 kg (economy) | 15 kg (business/first) |
| Etihad Airways | 7 kg (economy) | 12 kg (business) |
| flydubai | 7 kg | Strictly enforced |
| Air Arabia | 7 kg |
South and Southeast Asia
| Airline | Weight Limit |
|---|---|
| IndiGo (India) | 7 kg |
| Air India | 8 kg |
| Thai Airways | 7 kg |
| Malaysia Airlines | 7 kg |
| Cebu Pacific | 7 kg |
How Enforcement Actually Works
Weight limits on paper and weight limits in practice are often very different things.
Most likely to weigh your bag:
- Chinese carriers at Chinese airports
- Air Asia and other Southeast Asian LCCs
- Ryanair and Wizz Air at some European airports during high-enforcement periods
- flydubai and Air Arabia at Dubai/Sharjah
Least likely to weigh your bag:
- US carriers (almost never)
- European full-service carriers on busy routes
- Most carriers during gate rush boarding
Enforcement is also contextually variable. A lightly loaded flight may have crew who ignore a heavy bag; a weight-sensitive short-haul flight may see stricter checks.
Tips for Managing Weight Limits
Wear your heaviest items. Wearing your laptop, thick jacket, or boots through security and onto the plane keeps that weight off the scale. This is legal and widely practiced.
Use a luggage scale at home. A small digital luggage scale ($10–15) removes the guesswork. Weigh your packed bag the night before the flight.
Carry a packing cube outside your bag. Some travelers carry a packing cube loosely in their arms at check-in and slip it back in the bag after weighing. This is a gray area — be aware that it could be challenged.
Check your fare type. Some airlines tier their weight allowances by fare class. Upgrading from basic economy to a mid-tier fare can increase your allowance from 7 kg to 10 kg or more.
Pack the right carry-on. Ultralight carry-on bags (under 1 kg) give you more weight budget for contents. A heavy hard-shell suitcase can eat 3–4 kg of your allowance before you pack a single item.
The Bottom Line
US travelers flying domestically or on US carriers enjoy the most relaxed carry-on weight regime in the world. Travelers flying Asian carriers — especially Chinese airlines — face the strictest limits, with consistent enforcement. European carriers sit in the middle, with limits ranging from 7 to 12 kg and enforcement that varies significantly by airport and route. Knowing your specific airline's limit before packing is the only reliable way to avoid surprises.
Frequently asked questions
Which airlines have no carry-on weight limit?▾
Most major US carriers — including American Airlines, Delta, United, Southwest, and JetBlue — do not enforce a weight limit on carry-on bags. They rely on size templates instead.
What is the most common carry-on weight limit?▾
7 kg (about 15 lbs) is the most common carry-on weight limit globally, used by many Asian, Middle Eastern, and European airlines including Singapore Airlines, Qatar Airways, and most Ryanair fares.
Do airlines actually weigh carry-on bags at the gate?▾
Most airlines do not routinely weigh carry-on bags. Weighing is most common at check-in desks and departure gates on Asian carriers, some Middle Eastern airlines, and strict European LCCs. US airlines almost never weigh carry-ons.
What happens if my carry-on is over the weight limit?▾
Enforcement varies: some airlines ask you to remove items and place them in a checked bag; others may charge a gate-check fee. In practice, enforcement is inconsistent — many overweight bags pass unchecked.
Does carry-on weight include the bag itself?▾
Yes. The carry-on weight limit applies to the total weight of your bag plus everything inside it. A typical soft-sided carry-on weighs 1.5–3 kg empty, so pack accordingly.
