• It goes by travel date. The new rules apply to Jetstar Airways flights departing from February 2, 2027.
• Jetstar Japan flights keep today's rules. So do group bookings of 10 or more passengers.
• A trip that spans the date gets two allowances. If you fly out before February 2, 2027 and back after it, your departing and return flights have different carry-on rules.
• Booked before August 5, 2026? For flights from February 2, 2027, you get Priority Carry-on included, whatever your fare or bundle. Group bookings are excluded. Jetstar also says it will refund an extra 7 kg carry-on option you already paid for. Check your allowance in Manage booking.

Jetstar sells checked bags by total weight, not by number of bags. You can add them when you book, later in Manage booking, or at the airport.

• Online: prices vary by route and show only in the booking flow or Manage booking. Jetstar publishes no online price list, so we don't estimate one.
• Total: up to 40 kg per passenger.
• Per item: no single item over 32 kg. With a 35 kg or 40 kg allowance, you must split it over at least two bags. Anything over 32 kg goes as freight.
• Starter fare: no checked bag included.
• Business: 30 kg included, and you can buy up to 10 kg more, to 40 kg.

These are the prices Jetstar lists for checked bags bought at the airport. Your online price for the route shows when you book.

15 kg or 20 kg? Jetstar's own pages differ on how much weight the airport price covers. The airport prices page says it covers the first 20 kg on Jetstar Airways flights, from January 15, 2026. Another Jetstar help page, and a line on the same prices page, still say the first 15 kg. We can't settle this from Jetstar's pages, so check the allowance shown in your booking, or ask Jetstar, before you pay at the counter.

If you connect from a domestic flight to an international one, Jetstar charges international rates for the whole trip.

Any bag or item with a side longer than 1 m (39 in), including wheels, handles and packaging, is oversized. Each passenger can bring up to 2 oversized items. The fee is per item, per flight, and it adds no extra weight allowance: the item's weight still counts toward your checked kilos.

There's no oversized fee for mobility aids, assistive devices, medical equipment or infant items. More on bulky bags: overweight and oversized bags explained.

These apply under the current rules. Jetstar says it will update its gate fees before February 2, 2027 and hasn't published the new ones yet.

The gate hold fee applies when a bag is over 10 kg, your total is over 14 kg, the extra 7 kg option is sold out, or a bag is too big or one item too many. It applies even if you've already bought checked bags. The extra 7 kg option isn't sold on flights between Australia and New Zealand.

These use only Jetstar's published airport prices, and bags of 15 kg or less, which every Jetstar page agrees the airport price covers.

• One 15 kg bag, Australian domestic flight, one way: 120 Australian dollars. Round trip: 120 plus 120, so 240.
• Family of four, one 15 kg bag each, Australian domestic: 4 x 120 = 480 Australian dollars one way, 960 for the round trip.
• One 15 kg bag on an international Jetstar Airways flight: 112 US dollars one way.
• A surfboard on a domestic round trip: 30 Australian dollars per flight if added when booking, so 60, or 35 per flight at the airport, so 70.
• A 9 kg cabin load on a Starter fare today, domestic: that's over 7 kg. Adding the extra 7 kg option at check-in costs 60 Australian dollars; at the gate it's 85, so sorting it at check-in saves 25. If that option is sold out, the bag goes in the hold for 125.

Under the new Flex bundle, if Priority Carry-on is sold out, only the 20 kg checked option is offered. Jetstar notes that inclusions can vary by flight length, aircraft and route.

Jetstar Japan flights keep today's carry-on rules after February 2, 2027: 2 items, 7 kg combined, main item up to 56 x 36 x 23 cm. At the airport, a checked bag is priced for the first 15 kg: 4,600 yen on domestic flights and 6,500 yen on international flights, then 1,000 yen or 2,000 yen per extra kilo.

On a trip that mixes Jetstar Airways and Jetstar Japan flights from February 2, 2027, bundles give you an underseat bag on the Jetstar Airways legs and 7 kg across 2 items on the Jetstar Japan legs. Jetstar's advice is to pack for the lowest allowance. Jetstar also says Jetstar Japan is being rebranded, with the change due to finish by June 2027, and that flights carry on as normal in the meantime.

• The gate costs more than check-in. The extra 7 kg option is 60 Australian dollars at domestic check-in and 85 at the gate.
• Buying checked bags doesn't protect you at the gate. The gate hold fee still applies to a cabin bag that's over the limits.
• Check the date of each flight. A return trip either side of February 2, 2027 has two different cabin allowances.
• Weight, not pieces. Two bags can share your checked kilos, but none can be over 32 kg.
• Oversized is about length. A light item with one side over 1 m still pays the oversized fee.
• Connecting to another airline? Your bags may not go through. See connecting flights bag rules.
