Jetstar Baggage Policy 2026: Fees, Sizes & Rules Explained 

Jetstar’s standard carry-on allowance is 7kg across two items (main: 56×36×23cm; small: under-seat), and checked baggage is not included on Starter fares. Airport baggage fees are significantly higher than online prices AUD $120 for 20kg on domestic flights versus roughly AUD $45–70 when added online. Always pre-purchase baggage to avoid gate fees.

What Is Jetstar’s Baggage Allowance in 2026?

Jetstar’s baggage allowance depends on your fare type. Every Starter fare includes carry-on only: two items with a combined 7kg. Checked baggage is not included and must be purchased separately in weight blocks up to 40kg. Bundle fares include checked baggage 20kg with Plus, 30kg with Max and Business.

What Is Jetstar’s Carry-On Baggage Size and Weight Allowance?

Jetstar’s carry-on allowance on Starter fares is two items with a combined weight of 7kg. The main item must not exceed 56×36×23cm (H×W×D), including wheels and handles, and must fit in the overhead locker. The secondary item such as a handbag or slim laptop bag must fit under the seat in front of you.

In inches, the main carry-on size limit is approximately 22″ × 14″ × 9″. This is on the smaller side compared to many full-service carriers, so a standard 20-inch cabin bag will typically fit, but check your bag against these exact dimensions before packing.

With 14kg of carry-on (available via the Flex bundle, Business Class, or the paid +7kg top-up on selected routes), the combined weight doubles, but no single item can exceed 10kg. Spread weight across both items.

Carry-on size and weight at a glance:

Is Jetstar Strict on Carry-On Luggage?

Yes Jetstar is one of the strictest low-cost carriers for carry-on enforcement. Bags are physically weighed and sized at the boarding gate, and if you exceed the 7kg combined limit, you will be charged an excess fee that is significantly higher than the online price.

A laptop, handbag, and small backpack all count toward your 7kg combined total. There is no grace allowance. If your bag is over the limit at the gate:

• You can purchase +7kg Extra Carry-On (if available and if your total won’t exceed 14kg): AUD $85 domestic / AUD $110 international
• Your bag gets checked into the hold: AUD $125 domestic / AUD $175 international

These fees apply even if you have pre-purchased checked baggage.

Can I Bring a Backpack and a Carry-On on Jetstar?

Yes, you can bring a backpack and a carry-on bag on Jetstar as long as the combined weight of both items does not exceed 7kg and neither item has more than two pieces total. The backpack must either fit in the overhead locker (within 56×36×23cm) or under the seat in front of you.

In practice: if your backpack is your main item (overhead), it counts toward the 56×36×23cm size limit. If it’s your secondary item, it just needs to fit under the seat. The critical point is weight many travelers underestimate how quickly a laptop, chargers, and a water bottle bring a 7kg total to its limit.

What Is Jetstar’s Checked Baggage Allowance?

Jetstar’s checked baggage is sold in weight blocks of 15kg (domestic), 20kg, 25kg, 30kg, 35kg, or 40kg per passenger. No single bag may weigh more than 32kg, regardless of total allowance purchased. There is no limit on the number of bags as long as the combined weight falls within your purchased allowance.

You can purchase up to 40kg per passenger. This is most relevant for families or travelers with sporting equipment. Importantly, Qantas Frequent Flyer status at any tier does not add any Jetstar checked baggage allowance. Neither does Club Jetstar membership.

How Much Is Jetstar Checked Baggage?

Jetstar checked baggage costs from approximately AUD $45 online for 15kg on a domestic flight, and around AUD $70 for 20kg on an international flight. Airport prices are dramatically higher AUD $120 for the first 20kg on domestic routes, and AUD $170 internationally.

Price comparison: online vs. airport:

Real-world scenario: You check in at Sydney Airport with 25kg of luggage but no pre-purchased bag. On a domestic Jetstar Airways flight, you’d pay AUD $120 for the first 20kg, then AUD $30 × 5kg = AUD $150 for the overage a total of AUD $270 for a bag that may have cost AUD $50 online.

Note: From 15 January 2026, the first airport block for all Jetstar Airways (JQ) flights both domestic and international increased to 20kg (previously 15kg on some routes), per Jetstar’s official policy page.

What Is the Jetstar Overweight Baggage Fee?

Jetstar’s overweight baggage fee is AUD $30 per kg over your allowance on domestic flights, and AUD $50 per kg over your allowance on international flights. These fees apply at the airport check-in desk for each kilogram above your pre-purchased or airport-purchased allowance.

Oversized items any bag with a single side longer than 100cm, including wheels, handles, and packaging incur a separate handling fee:

• Before July 17, 2026: AUD $25 per oversized item (JQ domestic and international)
• From July 17, 2026 at time of booking/Manage Booking: AUD $30 domestic / AUD $40 international
• From July 17, 2026 at the airport: AUD $35 domestic / AUD $45 international

Oversized items still count toward your total checked baggage weight allowance.

What Special Baggage Does Jetstar Allow?

Jetstar allows sports equipment (bikes, surfboards, golf clubs), musical instruments, and family items such as strollers. Sports gear and instruments count toward your purchased checked baggage weight allowance. Any item with a side exceeding 1 metre also incurs an oversized handling fee. Jetstar does not carry pets.

• Sports equipment: Bikes, golf clubs, surfboards, and ski gear count toward checked baggage weight. Items over 1m on any side incur the oversized fee. Book enough weight allowance in advance.
• Musical instruments: Small instruments can travel as carry-on within the 7kg limit. Larger instruments can be checked (within weight allowance) or carried in the cabin if you purchase a dedicated seat.
• Family items: Strollers, portable cots, high chairs, and car seats travel free for passengers flying with infants or young children.
• Pets: Jetstar does not carry pets in the cabin or as checked baggage on any route. Only registered assistance animals are permitted on eligible services.

How Do You Add Baggage After Booking on Jetstar?

You can add baggage to an existing Jetstar booking via Manage Booking on the Jetstar website or app at any time before your flight. Adding baggage online after booking is more expensive than adding it at the original time of purchase, but significantly cheaper than paying at the airport.

The pricing hierarchy is: cheapest at initial booking, slightly more via Manage Booking, most expensive at the airport. If you realize after booking that you need a bag, log into Manage Booking immediately rather than waiting until the airport.

How Do You Check Baggage on Jetstar? (Baggage Check-In Policy)

To check baggage on Jetstar, proceed to a Jetstar check-in counter or bag drop at the airport with your pre-purchased baggage allowance confirmed in your booking. Online check-in opens 24–48 hours before departure. At the airport, bag drop counters close 30 minutes before domestic departures and 60 minutes before international departures.

If you purchased your bags in advance, you will receive a bag tag at check-in. Keep this tag receipt you will need it if your bag is delayed or lost.

Do You Need to Print Your Boarding Pass for Jetstar?

No you do not need a printed boarding pass for Jetstar. A digital boarding pass displayed on your phone through the Jetstar app, a downloaded PDF, or a mobile wallet pass is accepted at all Jetstar airport gates in Australia. However, having a backup (screenshot or print) is recommended for international routes where airport scanners vary.

What Is Not Allowed in Checked Luggage on Jetstar?

Jetstar prohibits several categories of items in checked baggage, in line with international aviation safety regulations:

• Spare/loose lithium batteries  must travel as carry-on
• Hoverboards, electric scooters, and electric unicycles  banned entirely
• Weapons, replica weapons, and sharp objects (unless declared and packed to strict standards)
• Hazardous chemicals, flammable liquids, and compressed gases
• Liquids in carry-on over 100ml (international flights  must be in a sealed 20×20cm bag, one per passenger)
• Inorganic powders exceeding 350ml or 350g (international flights departing Australia)

Always review Jetstar’s official dangerous goods page before packing, as regulations can vary by departure country and route type.

How Does the Jetstar Baggage Tracker Work?

Jetstar does not offer a real-time baggage tracking app. If your checked bag is delayed, lost, or damaged, you must report it at the Jetstar baggage services desk in the arrivals hall before leaving the airport. Reporting after you leave significantly reduces your ability to claim.

When reporting:

1. Go directly to the Jetstar baggage desk in arrivals
2. Present your bag tag receipt and boarding pass
3. You will receive a reference number for follow-up
4. Keep all receipts for essential items purchased while waiting

For international flights, liability coverage follows the Montreal Convention limit of approximately 1,288 SDR per passenger (Special Drawing Rights, equivalent to roughly AUD $2,500–$2,800 depending on the exchange rate). Domestic coverage applies under a separate scheme.

Critical note: Jetstar generally does not transfer bags between flights at stopovers. On connecting itineraries (unless they meet specific exceptions for international Jetstar-to-Jetstar connections or certain partner airline bookings on the same ticket), collect your bag and re-check it yourself. Allow adequate connection time.

Jetstar Baggage Policy for Domestic Flights

On Jetstar domestic flights in Australia, carry-on rules are identical to international: 7kg combined across two items. Checked baggage is not included on Starter fares and is purchased separately. The airport price for the first 20kg on domestic Jetstar Airways (JQ) flights is AUD $120 (effective January 15, 2026). Excess weight is charged at AUD $30 per kg.

The main domestic-specific difference is that the 15kg block is available for purchase (domestic only) and the excess baggage per kg rate is lower (AUD $30 versus AUD $50 internationally).

How Do You Avoid Excess Baggage Fees on Jetstar?

Jetstar’s fee structure is designed to reward early packing decisions. Here’s how to stay ahead of it:

• Add checked baggage at the time of booking  the cheapest window by a significant margin
• Weigh your carry-on at home before leaving  include your handbag and laptop
• Measure your main carry-on bag against 56×36×23cm, including any external pockets or wheels
• Compare bundle vs. Starter + bag   if you need 20kg, a Starter Plus bundle sometimes costs less than a Starter fare plus a separate bag purchase
• Don’t assume Qantas FF status helps  it provides zero extra allowance on any Jetstar flight
• Book the +7kg carry-on top-up online if 7kg won’t be enough  airport and gate prices are 40–100% higher
