Qantas Carry-On Rules: Size, Weight & Class Guide (2026)

Qantas is Australia's flag carrier and one of the most recognisable airlines in the world. While its cabin bag policy is broadly straightforward compared to European budget carriers, the airline takes weight enforcement seriously — particularly on its extensive domestic network. This guide covers everything you need to know about Qantas carry-on rules across cabin classes, domestic vs international flying, and loyalty tier perks.

Qantas Carry-On Allowance by Cabin Class

Cabin	Bags	Size Limit	Weight Limit
Economy	1 carry-on + 1 personal item	56 × 36 × 23 cm + 40 × 30 × 15 cm	7 kg total
Premium Economy	1 carry-on + 1 personal item	56 × 36 × 23 cm + 40 × 30 × 15 cm	10 kg total
Business	2 carry-on bags	Must fit in overhead locker	14 kg combined
First	2 carry-on bags	Must fit in overhead locker	14 kg combined

Note that the personal item in Economy (40 × 30 × 15 cm) must fit under the seat in front of you. It does not go in the overhead locker.

Economy Class: What's Included

Economy passengers on Qantas are entitled to one carry-on bag and one personal item. The key dimensions to remember:

• Carry-on bag: 56 × 36 × 23 cm maximum
• Personal item: 40 × 30 × 15 cm maximum (laptop bag, handbag, or small backpack)
• Combined weight: 7 kg total for both items

The 56 × 36 × 23 cm carry-on size is slightly more generous in depth than many other carriers. A standard cabin-sized rolling suitcase typically fits within these dimensions, provided it's not overpacked and bulging at the seams.

The 7 kg total weight limit is where Qantas stands apart from airlines like Air Canada or United, which allow 10 kg or more in Economy. Seven kilograms goes quickly — a typical rolling cabin bag empty weighs 2–3 kg, leaving roughly 4–5 kg for contents. For trips of more than 2–3 days, careful packing is required to stay within allowance.

Weight Enforcement: Stricter Than Average

Qantas enforces its 7 kg carry-on weight limit more consistently than many full-service carriers, particularly on domestic Australian routes. Weight gauges at the gate are standard at major airports including Sydney (SYD), Melbourne (MEL), Brisbane (BNE), and Perth (PER).

What this means in practice:

• Staff may ask you to place your carry-on on a scale before boarding
• Bags over 7 kg may need to be checked into the hold
• If your bag is overweight, you may be charged the applicable checked baggage fee at the airport (typically higher than pre-purchasing)

On international long-haul flights, enforcement is generally more relaxed, but this is not something to rely on. The 7 kg limit applies to both domestic and international sectors.

Business and First Class Allowances

Qantas Business and First Class passengers receive a significantly more generous carry-on allowance:

• Two carry-on bags permitted
• Combined weight: 14 kg
• Each bag must fit in the overhead locker

The 14 kg combined limit effectively doubles the Economy allowance. For long-haul travellers in premium cabins, this allows a substantial carry-on wardrobe without check-in luggage. Business Class passengers also benefit from priority boarding, which means ample overhead locker space is available at the time of boarding.

Premium Economy

Premium Economy sits between Economy and Business in terms of carry-on allowance:

• One carry-on bag (56 × 36 × 23 cm) plus one personal item
• Combined weight: 10 kg — notably higher than Economy's 7 kg

The 10 kg limit makes Premium Economy a meaningfully better carry-on option for travellers who push the weight limit. The size dimensions remain the same as Economy, however.

Domestic vs International: Key Differences

Qantas operates a large domestic network within Australia as well as international long-haul routes to Asia, Europe, and North America. The published carry-on rules are identical across domestic and international travel, but there are practical differences:

Domestic routes: Stricter weight enforcement. Gate agents at major domestic hubs regularly weigh carry-on bags. Turnaround times are tighter, so compliance with weight limits is actively managed.

International routes: Less consistent enforcement of the weight limit, particularly on long-haul sectors. However, size limits are checked more systematically on heavily-booked international routes where overhead locker space is at a premium.

Codeshare and partner flights: If your Qantas booking includes a sector operated by a partner airline (Jetstar, Emirates, oneworld partners), the operating carrier's carry-on rules apply on that sector. Always check the operating carrier's policy at time of booking.

Qantas Club and Frequent Flyer Benefits

Qantas Frequent Flyer members can earn status across four tiers — Bronze, Silver, Gold, and Platinum. These tiers bring carry-on benefits beyond the base allowance:

• Qantas Club members and Silver status: Priority boarding, which means access to overhead locker space before general boarding begins
• Gold status: Additional checked baggage allowances; carry-on limits remain as per cabin class
• Platinum and Platinum One: Higher checked baggage allowances and eligibility for upgrade priority; the carry-on allowance matches the booked cabin

The key benefit of status for carry-on purposes is priority boarding. On full flights, overhead locker space fills quickly. Boarding early ensures your bag travels in the cabin rather than being gate-checked to the hold.

Prohibited and Restricted Items

Standard aviation security rules apply on Qantas:

• Liquids: 100 ml per container in a single transparent resealable bag (1-litre maximum)
• Lithium batteries: Spare lithium batteries must travel in carry-on (not hold luggage)
• Sharp objects: Knives, scissors over 6 cm, and similar items must go in checked baggage
• Duty-free liquids: Duty-free liquids purchased at the airport or on board may exceed 100 ml if in a sealed tamper-evident bag with the purchase receipt

On flights originating in Australia, liquids restrictions apply at security checkpoints as per the Australian Government's aviation security rules.

Tips for Travelling with Qantas

Use a luggage scale at home. Given Qantas's consistent weight enforcement, this is the single most effective way to avoid problems at the gate. Digital scales are inexpensive and give you a confirmed weight before you leave.

Wear your heaviest items. A heavy jacket, boots, or layers worn onto the plane don't count towards your carry-on weight. On a 7 kg limit, wearing rather than packing heavy items can make a significant difference.

Check your connecting sectors. If your Qantas itinerary includes connection with Jetstar (Qantas's budget subsidiary), be aware that Jetstar has different — and typically stricter — carry-on rules. Jetstar Economy usually includes only 7 kg carry-on with no separate personal item in the base fare.

Pack a personal item bag strategically. The 40 × 30 × 15 cm personal item travels under the seat and is not weighed separately. If you have a light laptop bag or handbag that fits within these dimensions, you can use it to carry items that would otherwise push your carry-on over 7 kg.

Pre-purchase checked luggage if you're unsure. If you're travelling for more than a week and want flexibility, Qantas's pre-purchased checked baggage is good value compared to the per-kg fees charged for overweight carry-on bags.

The Bottom Line

Qantas carries its carry-on weight enforcement more seriously than many full-service competitors, particularly on its domestic Australian network. Economy passengers get 7 kg across a carry-on and personal item — tight for longer trips but manageable with careful packing. Business and First Class passengers enjoy 14 kg across two bags. Use a luggage scale before you leave home, wear your heaviest items, and check the operating carrier rules on any codeshare sectors.
