Jetstar’s carry-on baggage policy depends on which fare you’ve booked — it isn’t a flat 7kg for everyone. Below is the current carry-on allowance by fare type, the exact size limit, the personal item / underseat bag rules, how strict Jetstar actually is at the gate, and what to do if your bag won’t fit.

Jetstar carry-on baggage allowance by fare
| Fare / Bundle | Carry-on included | Items allowed | Notes |
| Economy Starter | 7kg | 1 main item + 1 small item | Combined weight of both items can’t exceed 7kg |
| Starter Plus / Starter Max | 7kg (upgradable) | 1 main item + 1 small item | Add +7kg Extra Carry-On Baggage to take it to 14kg |
| Business | 14kg | 2 items (1 main, max 10kg each) + 1 small item | No single item over 10kg even within the 14kg total |
Jetstar carry-on size limit
Your main carry-on item must not exceed 56cm (H) x 36cm (W) x 23cm (D), including wheels and handles, and must fit in the overhead locker.
Jetstar personal item & underseat bag size
Jetstar allows one small personal item — a handbag, laptop bag, or similar — in addition to your main carry-on bag. Unlike the main item, Jetstar doesn’t publish an exact size limit for this second bag; the only rule is that it must fit under the seat in front of you, and its weight is counted together with your main bag toward your fare’s total (7kg or 14kg combined, not each).
As a practical guide, most underseat spaces on Jetstar’s aircraft comfortably fit a bag around 40cm x 30cm x 20cm or smaller — but since Jetstar doesn’t guarantee this figure, the safest test is still whether it slides under the seat in front of you at the gate.
What counts toward your carry-on weight
Everything you bring into the cabin is weighed together, including:
- Your main bag or backpack
- A handbag, purse, or laptop bag
- A laptop or other electronics
- A coat, umbrella, or camera
- Approved duty-free goods and infant food/items
There’s no separate free allowance for a handbag or laptop bag — it’s included in your 7kg or 14kg total, whichever your fare includes.
How strict is Jetstar with carry-on baggage?
Jetstar monitors carry-on baggage at the airport, both at check-in and the boarding gate, and will weigh bags it suspects are over the limit. If your bag is over your allowance, you’ll be asked to check it in, and excess baggage fees apply at the rate set for that day.
Does Jetstar weigh carry-on bags?
Yes. Jetstar staff weigh carry-on bags at check-in and at the boarding gate, particularly on busy flights. Weighing your bag with a portable luggage scale before you leave for the airport is the easiest way to avoid a surprise at the gate.
Jetstar carry-on rules: frequently asked questions
Can I bring a carry-on bag and a personal item?
Yes — every fare includes a main item and a small personal item, but their combined weight still has to stay within your fare’s total (7kg or 14kg).
Does my laptop count toward the 7kg limit?
Yes. A laptop, tablet, or other electronics are weighed as part of your total carry-on allowance, not separately.
What if my carry-on is over the limit?
You’ll need to check it in at the airport, and excess baggage fees will apply.
Are there exceptions for medical equipment or mobility aids?
Jetstar may allow exceptions for approved medical equipment or mobility aids that meet safety requirements. Contact Jetstar directly ahead of travel to confirm.
If your bag doesn’t fit: shipping ahead instead of checking in
Excess baggage fees at the gate are charged per kilo and can add up fast, especially on top-up or last-minute bookings. If you know before you travel that you’ll be over your carry-on or checked allowance — moving overseas, bringing gifts, travelling for work with equipment — it’s often cheaper and less stressful to ship the extra weight ahead of you rather than pay excess baggage at check-in.
DTDC Australia’s excess baggage shipping service lets you send extra luggage, boxes, or freight to your destination separately, so you arrive with just your carry-on and skip the gate scale altogether. For bigger moves, our international courier services cover door-to-door delivery to most countries worldwide. It’s worth comparing the cost against Jetstar’s excess and pre-purchased baggage fees before you fly, particularly for one-way moves or trips where you’re bringing more back than you took.
