Quick summary
Jetstar Airways announced on 5 August 2026 that overhead bin access will become a paid add-on from 2 February 2027, replacing the current combined 7kg carry-on limit with a size-and-location model. Every JQ booking will include one free under-seat bag measuring up to 40 × 30 × 20cm, but a standard wheelie case for the overhead locker will require purchase of Priority Carry-on, priced from A$25 to A$52 one way depending on route.
Passengers who booked before 5 August 2026 for travel from 2 February 2027 onward receive Priority Carry-on automatically at no charge. Jetstar Japan (GK) is excluded from the change and keeps its existing weight-based rules — a detail that matters on mixed itineraries.
For years, the most reliably contentious moment at any Jetstar gate was the bag weigh. Passengers crammed into a 7kg limit, crew enforced it inconsistently, and overhead bins filled up anyway. Jetstar Airways has now decided the whole system needs replacing.
Starting 2 February 2027, JQ’s Starter fares will include exactly one free item: an under-seat bag no larger than 40 × 30 × 20cm. A laptop bag, small backpack, or handbag fits that box. A cabin wheelie case does not. Overhead locker access becomes Priority Carry-on — a separate, capacity-controlled product that can sell out on busy routes before departure day.
The announcement covers all JQ-operated domestic Australian routes and international services including Bali, Tokyo Narita, and other Asia-Pacific destinations. Jetstar Japan flights are carved out entirely and retain the old weight-based structure. For travellers combining both carriers on a single trip, each segment operates under its own rules.
The six-month runway before implementation is deliberate. Jetstar is giving passengers time to adjust packing habits and booking decisions — but it also means anyone booking now for post-February travel needs to factor in the new cost structure immediately.
What the new rules actually mean at the gate
Under the current policy, Jetstar‘s Starter fares permit one main cabin item up to 56 × 36 × 23cm and one small item, with a combined weight cap of 7kg. Passengers can buy an extra 7kg allowance to reach 14kg total. That structure disappears on 2 February 2027.
The replacement is straightforward in principle but has a catch built into it. Every passenger gets the under-seat bag free. Overhead access requires Priority Carry-on, which bundles one overhead bag up to 56 × 36 × 23cm with priority boarding. The 10kg individual bag limit stays — passengers must still be able to lift and stow their own luggage — but routine gate weighing ends under the new system.
Pricing for Priority Carry-on, announced alongside the policy change, starts at A$25 one way on Launceston–Sydney, rises to A$33 on Sydney–Melbourne, reaches A$39 on Perth–Bali, and hits A$52 on Cairns–Tokyo Narita for selected flights between 2 February and 18 March 2027. Those are introductory reference prices; dynamic pricing means the actual cost will vary by route, date, and how early you buy.
Point Hacks reported the capacity-control detail that changes the risk calculation: Priority Carry-on is sold in limited quantities per flight. On popular routes, it can sell out. A passenger who skips it at booking and tries to add it at the airport may face a gate-check fee instead — a worse outcome than paying A$25 upfront.
| Route (one way) | Priority Carry-on price | Includes | Overhead bag limit |
|---|---|---|---|
| Launceston–Sydney | A$25 | Overhead bag + priority boarding | 56 × 36 × 23cm / 10kg |
| Sydney–Melbourne | A$33 | Overhead bag + priority boarding | 56 × 36 × 23cm / 10kg |
| Perth–Bali | A$39 | Overhead bag + priority boarding | 56 × 36 × 23cm / 10kg |
| Cairns–Tokyo Narita | A$52 | Overhead bag + priority boarding | 56 × 36 × 23cm / 10kg |

Transition protections apply to existing bookings. Passengers who reserved flights before 5 August 2026 for travel from 2 February 2027 onward will receive Priority Carry-on at no extra cost, as confirmed by the ABC. Those who had already paid for the additional 7kg carry-on option will be refunded. Bookings made from 5 August 2026 onward are subject to the new structure from day one.
One more wrinkle for split-date trips: if your outbound flight departs before 2 February 2027 and your return is on or after that date, the two sectors operate under different rules. Jetstar advises checking each flight individually in Manage Booking.
For flights from Australia to Japan and other Asia-Pacific destinations, the new pricing adds a meaningful per-trip cost that wasn’t previously visible in the base fare.

Why overhead bins became a revenue line
Jetstar is not the first low-cost carrier to make this move — it’s just the last major Australian one to get there. European and US budget carriers have charged for larger cabin bags for years, treating overhead space as a finite, sellable asset rather than a communal amenity included in every ticket. The logic is consistent: base fares stay low, ancillary revenue fills the gap, and passengers who want more pay for it explicitly.
What’s different about Jetstar’s version is the operational motivation behind it. The airline has cited gate-weighing friction and overhead bin congestion as the specific problems driving the change — not just revenue optimization. Crew time spent enforcing a 7kg combined limit at boarding gates is time not spent on other tasks, and disputes over overflowing bins create delays that affect the whole aircraft. A size-based model shifts the enforcement point to the booking stage rather than the gate.
The regulatory backdrop is worth noting. CASA‘s Part 91 rules still require carry-on items to be properly stowed for take-off and landing, and the 10kg individual bag limit reflects the safety requirement that passengers handle their own luggage. Jetstar’s commercial restructuring doesn’t touch those obligations. Separately, the ACCC‘s guidance on transparent fee disclosure will be relevant as the airline markets base fares that no longer include overhead access — advertising must not mislead consumers about what they’re actually buying. The Australian Government’s work on an Aviation Consumer Ombuds Scheme provides broader context, though this policy change is an airline decision, not a regulatory directive.
Steps to take before 2 February 2027
Priority Carry-on is capacity-controlled and priced dynamically — waiting until the airport is the worst possible strategy on a sold-out morning flight to Bali.
- Check your existing bookings now. If you booked before 5 August 2026 for travel from 2 February 2027, Priority Carry-on should be added automatically. Confirm this in Manage Booking rather than assuming it will appear at check-in.
- Add Priority Carry-on at the time of booking for new reservations. Introductory pricing starts at A$25 one way; buying at the airport, if it’s still available, will cost more. On routes like Cairns–Tokyo Narita, the gap is significant.
- Measure your under-seat bag before you fly. The free allowance is 40 × 30 × 20cm — smaller than most “personal item” bags sold as airline-compatible. A standard laptop backpack may be borderline; check dimensions before the gate.
- For mixed JQ and GK itineraries, verify each segment separately. Jetstar Japan retains the 7kg/14kg weight-based model. The JQ leg will require Priority Carry-on for overhead access; the GK leg will not. Packing to the JQ standard on both avoids mid-trip repacking.
- If your trip straddles 2 February 2027 — outbound before, return after — open each flight in Manage Booking and confirm which rules apply to each direction before you pack.
Watch: Jetstar’s dynamic pricing for Priority Carry-on beyond the introductory window. If prices on high-demand routes like Sydney–Melbourne climb significantly above A$33, it will reshape how the new policy compares against full-service alternatives on the same corridors.
Questions? Answers.
Does the new Jetstar carry-on policy affect Business Class passengers?
Business Class fares include overhead bag access under the new model — Priority Carry-on does not need to be purchased separately. Business Class passengers can also substitute a garment bag up to 114 × 60 × 11cm for the standard overhead item.
What happens if Priority Carry-on sells out before my flight?
If Priority Carry-on is no longer available for your flight and you arrive at the gate with an overhead-sized bag, Jetstar will check it into the hold — which typically incurs a checked baggage fee. Buying at the time of booking is the only reliable way to guarantee overhead access.
Are there any exceptions to the new under-seat-only rule for basic fares?
Yes, a few. Passengers travelling with a lap infant receive an additional free under-seat bag for baby items. One small duty-free bag is permitted on top of the standard allowance, subject to local requirements and proof of purchase. Dangerous goods rules — including restrictions on spare lithium batteries and e-cigarettes — are unchanged.
Will Jetstar weigh bags at the gate under the new system?
Routine cabin baggage weighing at boarding gates ends under the new policy. However, the 10kg individual bag limit remains in force — both for the free under-seat item and for Priority Carry-on overhead bags — and passengers are required to be able to lift and stow their own luggage, in line with CASA safety requirements.
