International Carry-On Rules: Singapore, Emirates, Qatar, United (2026)
Last verified: 14 May 2026
International airlines flying out of Australia run a wider mix of carry-on rules than domestic carriers. Asian and Middle East airlines tend to enforce strict 7kg limits. European airlines lean to 8kg. US carriers usually skip weight but enforce size aggressively. This is the 2026 breakdown for the major international carriers an Australian traveller is likely to fly, sourced from each airline's current policy page.
International airlines at a glance (2026)
| Airline | Economy carry-on | Weight | Personal item |
|---|---|---|---|
| Singapore Airlines | Linear sum 115cm | 7kg | 40 x 30 x 10 cm |
| Emirates | 55 x 38 x 22 cm | 7kg economy, 10kg premium | Same allowance, second piece on Bus/First |
| Qatar Airways | 50 x 37 x 25 cm | 7kg economy, 15kg business/first | Yes, plus personal item economy |
| United Airlines | 56 x 36 x 23 cm (22 x 14 x 9 in) | No published weight on standard fares | Yes, Basic Economy bin access restricted |
| Air New Zealand | Linear sum 118cm | 7kg economy, 14kg premium | Yes, fits under seat |
The general rule: pack to the strictest carrier on your itinerary. If you fly Sydney to Singapore on Qantas (7kg) then connect to Bali on Scoot (also 7kg), the Scoot rule still binds for the second leg.
Singapore Airlines: 7kg across all classes
Per Singapore Airlines's cabin baggage page, First, Business, Premium Economy, and Economy all get the same cabin baggage allowance: 1 piece up to 7kg, sum of length plus width plus height must not exceed 115cm.
Plus one of: handbag, laptop bag, or small camera bag, max 40 x 30 x 10 cm (80cm linear). If this additional item exceeds the dimensions, it counts as your main cabin baggage and you don't get a second piece.
The fleet is widebody: A350-900, 777-300ER, 787-10, A380-800. All have generous overhead bins; any 40L carry-on within the 115cm linear sum will fit cleanly. The A380 upper deck has smaller bins than the main deck; if you're flying Suites or Business on the upper deck, expect tight bin space.
Emirates: 7kg economy, 10kg premium, 7+7kg business
Per Emirates's cabin baggage rules page:
- Economy: 7kg, max 55 x 38 x 22 cm.
- Premium Economy: 10kg, same dimensions.
- Business / First: 1 piece 7kg (55 x 38 x 22 cm) plus 1 briefcase or garment bag at 7kg (briefcase max 45 x 35 x 20 cm).
- Departures from Brazil: 10kg in all classes.
- India boarding: 1 piece only, max 115cm linear.
Emirates fleet: A380-800 and 777-300ER widebody. The A380 main deck has the largest overhead bins in commercial service; the upper deck (where First Class private suites sit on Emirates) has noticeably smaller bins. The 777-300ER has large pivoting bins that take any standard 40L carry-on.
Qatar Airways: 7kg economy, 15kg business
Per Qatar Airways's baggage allowance page, the 2026 carry-on allowance is:
- Economy: 1 piece of hand luggage up to 7kg, plus 1 personal item (small handbag or laptop bag).
- Business / First: 2 pieces totalling 15kg.
- Maximum dimensions: 50 x 37 x 25 cm for any single piece, all classes.
The fleet on Australian routes is widebody: 777-300ER, A350-1000, 787-9. All have large centre bins that take any 40L carry-on. Qatar Airways generally enforces carry-on weight at check-in on Sydney and Melbourne departures.
United Airlines: size enforced, weight rarely
United's published carry-on rule is 22 x 14 x 9 inches (~56 x 36 x 23 cm) including handles and wheels. There's no published weight limit on standard fares. The key wrinkle is Basic Economy: passengers on Basic Economy fares don't get overhead-bin access on most US domestic flights and must travel with a personal-item-sized bag only (17 x 10 x 9 inches).
The official page is at united.com. Verify your fare class includes overhead-bin access before flying.
Fleet: mix of widebody (777-300ER, 787-9, 767) on Australian routes and 737/A320 narrowbody on US domestic. The A321neo retrofits with Airspace XL bins are the newest single-aisle option.
Air New Zealand: 7kg economy, 118cm linear, 14kg premium
Per Air New Zealand's carry-on baggage page:
- Economy: 1 piece, up to 7kg, total linear dimensions 118cm.
- Premium Economy / Business Premier: Up to 14kg combined across pieces, with each individual piece max 10kg.
Fleet: 787-9 Dreamliner on long-haul international (Auckland-LAX, Auckland-SFO, Auckland-Tokyo), A320neo and A321neo for trans-Tasman and domestic NZ routes. The 787-9 has generous bins; the A320/A321 are narrowbody with shallow side bins.
What kind of bag works best for international flights
Two factors govern the choice. First, which aircraft you'll spend the most hours in. Second, how strict the airline is on weight.
For long-haul widebody routes (A380, 787, 777, A350): centre bins are deep and accommodating. Hardshell suitcases fit fine. The bag-shape question matters less. Weight is the bigger constraint, especially on Asian carriers (Singapore, Cathay, JAL) where 7kg is strictly enforced at check-in.
For narrowbody connections after a long-haul leg (e.g. Singapore Airlines into Singapore, then Scoot on to Bali; or Qantas to LAX, then United to a US domestic): the narrowbody side bins are shallower. Soft-sided bags fit better.
The general international traveller's pick is a soft-sided 40L carry-on with compression packing cubes inside. The cubes manage the 7kg weight constraint that Asian and Middle East carriers enforce; the soft exterior fits both widebody and narrowbody bins.
The strictest-carrier rule
When you book a multi-leg international itinerary, the strictest carrier on your trip is the one your bag must fit. Examples:
- Sydney - Singapore - Bali (Qantas + Scoot): Qantas 7kg, Scoot 7kg combined. The Scoot rule binds because it includes the personal item.
- Melbourne - Doha - London (Qatar Airways throughout): 7kg, single carrier.
- Sydney - LAX - Denver (Qantas + United): Qantas 7kg on the long-haul, United no-weight-but-strict-size on the US domestic. United is the binding size limit; Qantas is the binding weight limit.
- Brisbane - Singapore - Tokyo (Singapore Airlines throughout): 7kg, 115cm linear, single carrier.
The safe move: take the lowest published weight across all your legs as your packing target. Take the smallest published dimensions across all your legs as your bag size target.
FAQ
What's the carry-on weight for international flights from Australia?
Varies by carrier. Asian and Pacific airlines (Singapore Airlines, Cathay, JAL, Air NZ) typically 7kg. Middle East carriers (Emirates, Qatar, Etihad) typically 7kg economy. European airlines (Lufthansa, Air France, BA) often 8kg. US carriers (United, American, Delta) usually no weight limit but enforce size strictly.
Is Singapore Airlines strict on carry-on weight?
Yes. The 7kg cap is enforced at check-in on most Sydney, Melbourne, and Brisbane departures. The 115cm linear sum is also checked with a sizer at the gate.
What's Emirates's carry-on weight in economy?
7kg, max 55 x 38 x 22 cm. Premium Economy gets 10kg. Business and First get 7kg main bag plus a 7kg briefcase or garment bag. Per the Emirates cabin baggage page.
Does United Airlines have a carry-on weight limit?
No published weight limit on standard fares. Size limit is 22 x 14 x 9 inches (~56 x 36 x 23 cm) and is enforced strictly with sizers at the gate. Basic Economy passengers don't get overhead-bin access on most US domestic routes.
What's Air New Zealand's carry-on rule?
Economy: 1 piece up to 7kg, total linear dimensions 118cm. Premium Economy and Business Premier: up to 14kg combined, no single piece over 10kg.
Why are international carry-on rules different from Australian domestic?
Different aircraft types and bin-shape conventions. Long-haul widebody aircraft (A380, 787, 777, A350) have larger bins; airlines flying these can be slightly more generous (10kg premium, 14kg business). Narrowbody-focused carriers tend to enforce strict 7kg. Asian carriers run a mix and enforce 7kg consistently across classes (Singapore Airlines).
What happens if my carry-on is over the limit on an Asian carrier?
Most Asian carriers enforce at check-in rather than at the gate. If your carry-on is overweight when you check in for your flight, it gets gate-tagged and travels in the hold, with a checked-bag fee added to your booking. The fee varies by airline but typically runs $50-$120 on long-haul routes.
What Cubey makes for this
The Wheels Up Bundle ($148) is built for long-haul international travel. It packages the Signature Compression Packing Cube Set, the Hang-Up Toiletry Kit (TSA-friendly clear pouch sized to the 100ml rule), and the Tech Tidy cable organiser at 25 percent off the individual prices. Compression handles the 7kg weight constraint that Singapore Airlines, Emirates and Qatar all enforce; the toiletry kit handles the 100ml liquids screening; the cable organiser handles the airport-security tray.
For travellers who only need the cubes, the Signature Compression Packing Cube Set ($99) is the entry point.

The practical takeaway
Plan for the strictest carrier on your itinerary, not the average. Pack to 7kg using compression cubes if any leg of your trip is Asian or Middle East; that covers Singapore Airlines, Emirates, Qatar, Cathay, JAL, ANA, and the AU carriers. Add 100ml-rule-compliant liquids in a single 1-litre pouch on top so security is a 10-second pull-out. The all-airlines pillar covers the full set; the liquids guide covers the screening rule.
