The Qantas includes carry-on baggage in your ticket, but the exact baggage allowance depends on your route, cabin class, and aircraft type.

| Baggage Type | Price Range |

| Personal item | Free / Included |
| Carry-on bag | Included |

Carry-On Dimensions & Size Restrictions for Qantas
When it comes to carry-on size, Qantas follows fairly standard airline luggage dimensions—but with a few important details.
For most flights, your carry-on luggage size must not exceed:
- 56 cm x 36 cm x 23 cm (22 x 14 x 9 inches)
These dimensions apply to standard cabin bags like small suitcases or backpacks.
However, there are variations depending on how many pieces you bring:
- If carrying two smaller bags, each must be within 48 x 34 x 23 cm
- Garment bags are allowed as an alternative, with larger dimensions:
- 114 x 60 x 11 cm
On domestic flights, you’re allowed both an overhead bag and an underseat bag, but they still fall within the airline’s size restrictions.
One important note:
Qantas actively checks luggage dimensions at the airport. If your bag exceeds the permitted size, it won’t be allowed in the cabin and must be checked in.
When comparing Qantas with other airlines, you’ll notice its carry-on size limits are fairly standard, but the allowance structure is more flexible on domestic routes. For example, airlines like Ryanair carry-on size rules are much stricter with baggage allowance, while Jetstar carry-on size policy has tighter weight limits. If you’re used to flying in North America, the Alaska Airlines baggage rules may feel simpler compared to Qantas’ route-based variations.
Carry-On Weight Limit & Baggage Allowance
Weight limits are where Qantas differs depending on route and cabin class.
Domestic Flights (Australia)
- Total carry-on weight: 14 kg combined
- No single item can exceed 10 kg
International Economy
- Weight limit: 7 kg total
Premium Economy, Business & First
- One piece: 10 kg
- OR two pieces: 14 kg total (max 10 kg per item)
Flights from India
- Economy: 7 kg
- Business: 10 kg
- Only one carry-on bag allowed
This variation is crucial—especially if you’re flying internationally or connecting flights. Qantas advises passengers to follow the lowest baggage allowance across all legs of their journey.
Personal Item Size & Carry-On Bag Allowance
Qantas allows one personal item in addition to your main carry-on bag.
Examples include:
- Small handbag or purse
- Laptop in a slim bag
- Camera
- Reading material
However, Qantas does not specify exact personal item size dimensions.
Instead, the rule is simple:
Your personal item must fit under the seat in front of you.
For international flights:
- A personal item is allowed (except on some routes like flights from India, where only one main bag is allowed)
For domestic flights:
- You can bring:
- One overhead bag
- One underseat bag
- One personal item
This makes Qantas more generous than many airlines in terms of total cabin baggage allowance.
To better understand what qualifies as cabin baggage, it helps to know the difference between a carry-on and a personal item. Many travelers get confused here, especially with airlines like Qantas that allow multiple items on domestic flights. This guide on what counts as carry-on luggage explains it clearly, and you can also check carry-on vs personal item differences to avoid packing mistakes.
Carry-On Size Restrictions & Rules
Qantas has several specific carry-on restrictions you should know:
- Bags must meet both size and weight limits
- Oversized carry-on will be checked at the gate
- Power banks are limited to two per passenger
- Power banks cannot be used or charged onboard
- Dangerous goods and liquids must follow airport security rules
Liquids (when departing from Australia):
- Must be 100 ml or less
- Stored in a clear resealable plastic bag
Powders:
- Organic powders allowed
- Inorganic powders limited to 350 g or 350 ml
Also, certain travel accessories are prohibited:
- Devices that attach to seats
- Items that block aisles or access
Cabin crew has final authority on what’s allowed onboard.
Maximum Carry-On Size Allowed by Qantas
The maximum allowed size for a standard carry-on bag is:
- 56 cm x 36 cm x 23 cm
If you’re carrying multiple items:
- Each smaller item must fit reduced dimensions
- Total weight must still stay within limits
For bulky items (like instruments or artworks):
- You can bring them onboard only if you purchase an extra seat
- Size limits depend on cabin:
- Economy: up to 158 cm total dimensions
- Business: up to 169 cm
- First: up to 178 cm
Another common confusion is around luggage dimensions and how they’re measured. Qantas lists its cabin baggage size in centimeters, which can be tricky if you’re more familiar with inches. This quick breakdown of carry-on size cm vs inches makes conversions easy, while this guide on carry-on weight limits by airline helps you compare how strict different airlines are with baggage allowance.
How Strict Is Qantas With Carry-On Size?
Based on real traveler experiences:
- Qantas is moderately strict
- Weight checks are more common than size checks
- Domestic flights tend to be slightly more flexible
- International routes are more strictly enforced
At boarding:
- Staff may visually assess your bag
- On smaller aircraft (like Dash 8), bags are often collected at the gate
If your bag looks heavy or oversized, expect it to be weighed.
Carry-On Rules for Domestic vs International Flights
There are clear differences between domestic and international baggage rules.
Domestic Flights
- 1 overhead bag + 1 underseat bag + 1 personal item
- Total weight: up to 14 kg
- More flexible allowance
International Flights
- Economy: 1 bag (7 kg)
- Premium cabins: more flexibility
- Personal item allowed (except certain routes like India)
Special Case: Dash 8 Aircraft
- Only 1 carry-on bag + 1 personal item
- Weight limit: 7 kg
- Wheelie bags are collected at boarding and returned after landing
If you’re flying internationally, especially on multi-leg trips, understanding global carry-on rules becomes even more important. Qantas often requires you to follow the lowest baggage allowance across your journey. You can explore general international carry-on size limits and also review carry-on liquid size rules to make sure your bags pass airport security without issues.
What Happens If Your Carry-On Exceeds Size or Weight Limits?
If your carry-on exceeds Qantas size restrictions or weight limits:
- It will be checked in at the airport
- You may need to reorganize items
- Delays at boarding can happen
Qantas clearly states that oversized bags are not permitted in the cabin and must be checked.
Good news:
- Most Qantas tickets include checked baggage
- So you won’t always pay extra—but it can slow things down
Carry-On Allowance by Fare Class (Economy vs Business)
Here’s how baggage allowance changes by fare type:
Economy
- 1 carry-on bag
- Weight: 7 kg (international)
Premium Economy / Business / First
- Higher weight allowance
- Option for multiple smaller bags
- Total up to 14 kg
Infants & Children
- Infants: no separate allowance
- Parents can bring a small baby essentials bag
- Children (2+ years): same allowance as adults
Strollers
- Count as carry-on if within size limits
- Must be collapsible
- Not allowed in cabin on certain aircraft (e.g., Dash 8)
If you’re still unsure how Qantas compares in real-world scenarios, it helps to look at airline comparisons. For example, this comparison of American Airlines vs Delta carry-on size shows how policies differ across major carriers. You can also check Southwest vs United baggage rules to understand which airlines are more lenient when your bag is slightly over the allowed size.
