Quick summary
Jetstar Airways will charge passengers to use overhead bin space from 2 February 2027, replacing its previous 7kg free cabin allowance with a paid Priority Carry-on product. Launch pricing starts at A$25 on short domestic hops such as Launceston–Sydney and reaches A$52 one way on Cairns–Tokyo, with dynamic pricing meaning costs vary by route and demand. The policy applies to all JQ-coded services — Australian domestic and international — but not Jetstar Japan’s domestic network.
Bookings made before 5 August 2026 for travel after the changeover date will receive Priority Carry-on at no extra charge. Every passenger still gets one free under-seat bag, provided it fits within 40×30×20cm.
Jetstar announced on 5 August 2026 that overhead locker access will become a paid product across its entire JQ network starting 2 February 2027 — a structural shift in how Australia’s largest budget carrier prices cabin baggage. The airline’s new Priority Carry-on option starts at A$25 per flight and replaces the previous flat 7kg free carry-on allowance that passengers have relied on for years.
Travelers who can pack everything into a bag no larger than 40×30×20cm — roughly the size of a small backpack — still fly without paying extra. Anyone needing the overhead locker pays the route-specific fee, which is capped at the current cabin bag dimensions of 56×36×23cm and includes priority boarding.
The change affects every Australian domestic route and all international JQ flights, including high-volume leisure corridors like Perth–Bali and Cairns–Tokyo. Jetstar Japan’s domestic network operates under separate rules and is unaffected. For travelers already holding bookings made before 5 August 2026 for post-changeover travel, Jetstar says Priority Carry-on will be added automatically at no cost, with refunds issued where passengers had pre-paid for extra carry-on weight beyond 7kg.
CEO Stephanie Tully framed the policy as an efficiency measure, saying it will streamline boarding, reduce delays, and let customers pay only for what they need. Social media reaction has been sharply divided — calls for boycott alongside comments labelling the fee a “cash grab” sit alongside travelers who argue it will finally clear the boarding bottlenecks caused by oversized bags and last-minute locker searches.
What the new rules actually cost, route by route
Jetstar’s official baggage guide confirms the full dimension and fee structure. Priority Carry-on is sold as a dynamic product — prices are set per route and adjusted by demand, so the figures below reflect launch pricing rather than a fixed schedule. Passengers who miss the pre-purchase window and arrive at the gate with an oversized bag face being redirected to checked baggage, almost certainly at a higher airport fee.
| Route (one way) | Priority Carry-on fee | Return trip cost | Includes |
|---|---|---|---|
| Launceston–Sydney | A$25 | A$50 | Overhead locker + priority boarding |
| Sydney–Melbourne | A$33 | A$66 | Overhead locker + priority boarding |
| Perth–Bali | A$39 | A$78 | Overhead locker + priority boarding |
| Cairns–Tokyo | A$52 | A$104 | Overhead locker + priority boarding |
Fees are dynamic and subject to change. Prices sourced from Jetstar’s August 2026 announcement materials.
The previous 7kg weight check disappears entirely under the new model. Gate agents will assess under-seat bags by size rather than weight, and Priority Carry-on holders board ahead of passengers carrying only under-seat items. Jetstar’s guidance indicates that the number of Priority Carry-on passes per flight is capped — meaning travelers who wait to buy at the airport may find the product sold out, leaving only the checked baggage option.
For families traveling together, the arithmetic compounds fast. Two adults and two older children each needing overhead space on a Sydney–Melbourne return adds A$264 to what was previously included in the base fare.

Why this lands differently in Australia than it did in the US
US ultra-low-cost carriers Frontier and Allegiant have charged separately for overhead bin access for years — it is simply how their pricing architecture works, and American travelers have largely adjusted their expectations accordingly. Australia is arriving at this model later, which means the psychological gap between what passengers expect and what they now pay is wider. Aviation strategy consultant Koen Karsbergen put it plainly: Jetstar is catching up to a market that got there years ago, but nobody likes paying for something they previously had for free.
That gap matters commercially. Qantas and Virgin Australia still include a standard overhead-capable carry-on in economy base fares. On a route like Sydney–Melbourne, where all three carriers compete, Jetstar’s headline fare may look cheaper — but once a traveler adds A$33 each way for overhead access, the total cost converges toward full-service pricing. The comparison becomes even tighter on international routes where Jetstar’s base fares carry the most apparent discount.
There is a genuine upside for one traveler segment: anyone who genuinely travels with only a compact under-seat bag now avoids the old weight-based surcharges entirely and pays less than before. The policy effectively redistributes cost from minimalist packers to everyone else.
How to protect your trip cost before February 2027
Priority Carry-on inventory is capped per flight and priced dynamically — the cheapest fares on this add-on go early, and airport purchase may not be available at all.
- Audit every JQ booking you hold: Check all Jetstar Airways bookings for travel from 2 February 2027 onward. Confirm whether Priority Carry-on is included (pre-5 August 2026 bookings) or needs to be purchased. Do this now — prices are at launch levels and will rise.
- Add Priority Carry-on at booking, not at the gate: Jetstar’s enforcement model redirects unprepared passengers to checked baggage at airport rates. Pre-purchasing locks in the lower dynamic price and guarantees overhead space before the flight sells out of passes.
- Run the real fare comparison: When pricing Jetstar against Qantas or Virgin Australia on routes like Sydney–Melbourne or flights from Australia to Japan, add the applicable Priority Carry-on fee to Jetstar’s base fare before deciding. The gap narrows significantly once overhead access is priced in.
- Consider the under-seat-only option seriously: A bag within 40×30×20cm travels free. For short domestic hops or trips where you’d otherwise pay A$33–A$52 each way, a compact packing strategy can eliminate the fee entirely — and Jetstar has removed the old 7kg weight limit for under-seat bags, so weight is no longer the constraint.
- Families should model the full cost early: Multiple overhead bags multiply quickly. A family of four on a return Cairns–Tokyo itinerary could face over A$400 in Priority Carry-on fees alone — enough to shift the value calculation toward a full-service carrier that bundles cabin bags.
Watch: Whether Virgin Australia or regional carriers adjust their carry-on policies in response. If Jetstar’s on-time performance data improves materially after February 2027, expect other Australian budget operators to cite it as justification for similar moves.
Questions? Answers.
Does the Priority Carry-on fee apply to Jetstar Asia or Jetstar Japan flights?
No. The new overhead locker fee applies only to Jetstar Airways (JQ) services — Australian domestic and international routes. Jetstar Japan’s domestic network is explicitly excluded and retains its existing carry-on policy. Jetstar Asia operates under separate rules; check its baggage pages directly before booking.
What happens if I bring an oversized bag to the gate without paying for Priority Carry-on?
Jetstar’s enforcement model redirects passengers with oversized bags and no Priority Carry-on entitlement to checked baggage at the airport. Airport checked baggage fees are typically higher than pre-purchased rates, and there is no guarantee of same-flight carriage on busy routes. The safest approach is to pre-purchase or pack to under-seat dimensions.
Is there a weight limit on the free under-seat bag?
Jetstar has removed the previous 7kg total cabin baggage weight limit under the new model. Under-seat bags are assessed by size — 40×30×20cm — rather than weighed. This means a dense but compact bag is no longer penalised, which benefits travelers who pack efficiently into small luggage.
Will Qantas frequent flyers get any Priority Carry-on benefit on Jetstar flights?
Jetstar has not announced any automatic Qantas Frequent Flyer status exemptions from the Priority Carry-on fee as of the August 2026 announcement. Check Jetstar’s fare rules and any Qantas–Jetstar benefit updates before booking, as this may be clarified closer to the February 2027 launch.
