Jetstar Asia (3K) operates from its hub at Singapore Changi Airport and flies to destinations across Southeast Asia, China, Japan, and Australia. As a low-cost carrier, every kilogram of checked baggage costs extra. In 2024, the airline revised its checked baggage fee structure and cabin baggage allowances. If you are booking a flight from Singapore to Bangkok, Penang, Manila, or Osaka, knowing exactly what you pay for baggage can save you S$30 to S$80 per round trip. This article details current fees, weight limits, size restrictions, and practical tips to avoid surprise charges at check-in.
A Baggage Fee Model That Changed in 2024
In early 2024, Jetstar Asia quietly updated its checked baggage fee tiers and introduced stricter enforcement of cabin baggage dimensions. The airline now operates three main fare bundles: Starter, Starter Plus, and Starter Max. Each bundle includes different baggage allowances:
- Starter: One personal item (under-seat bag only, max 7 kg, dimensions 48 x 34 x 20 cm). No checked bag included.
- Starter Plus: One carry-on bag (max 7 kg, dimensions 56 x 36 x 23 cm) plus one personal item. One checked bag of up to 20 kg included.
- Starter Max: Same cabin allowance as Starter Plus, plus two checked bags of up to 20 kg each (total 40 kg). Also includes seat selection and priority boarding.
If you book a Starter fare and later add a checked bag, you pay the per-bag fee. These fees are non-refundable and must be paid at least 4 hours before departure online, or at the airport counter.
Current Checked Baggage Fees (SGD)
All prices below are in Singapore Dollars (SGD) for flights originating from Singapore. Prices for flights booked from other countries may vary.
| Baggage Weight | Online (4+ hours before departure) | At Airport / After Online Cut-off |
|---|---|---|
| 15 kg | S$33 | S$55 |
| 20 kg | S$38 | S$60 |
| 25 kg | S$48 | S$75 |
| 30 kg | S$58 | S$90 |
| 35 kg | S$68 | S$105 |
| 40 kg | S$78 | S$120 |
Fees for flights to/from Japan, China, and Australia are generally S$5-10 higher per tier. For example, a 20 kg bag on a Singapore, Osaka route costs S$42 online, S$65 at the airport. If you are flying to Denpasar (Bali) or Kuala Lumpur, the above table applies.
Jetstar Asia does not allow a second checked bag at a flat fee. If you need more than 40 kg, you must purchase an additional bag (up to 20 kg) online for S$60. This is common for travellers who carry diving equipment or bulky sports gear.
Cabin Baggage Rules: Current Limits and Enforcement
Jetstar Asia’s cabin baggage policy underwent a tightening in mid-2023, and in 2024 the airline actively enforces size and weight limits at the gate. For passengers who book Starter Plus or Starter Max fares, the carry-on bag allowance is:
- One carry-on bag weighing up to 7 kg, dimensions not exceeding 56 cm (height) x 36 cm (width) x 23 cm (depth).
- One personal item (handbag, laptop bag, small backpack) weighing up to 7 kg combined with the carry-on bag. The personal item must fit under the seat in front, dimensions max 48 x 34 x 20 cm.
Passengers who book Starter fares are only allowed the personal item, no standard carry-on bag. This rule is strictly enforced at Changi Airport Terminal 1 and 4 departure gates. If your bag exceeds size or weight, you are required to check it at the gate for a fee of S$60 (paid directly at the gate counter).

What Counts as a Personal Item?
Jetstar Asia defines a personal item as a single bag that can fit completely under the seat in front. Acceptable examples include:
- A small handbag or clutch (max 48 x 34 x 20 cm)
- A thin laptop bag (not a backpack with multiple compartments)
- A slim briefcase
Items that do not qualify: a standard backpack (even if mostly empty), a duffel bag, a tote bag that is bulging, or any bag that cannot slide into the under-seat sizer. Duty-free shopping bags count as a second personal item and may be restricted if you already hold a bag.
Overweight and Oversize Baggage Penalties
Jetstar Asia charges heavy penalties for baggage that exceeds the weight or piece limit. The airline uses a strict per-kg system: if your pre-purchased bag is 20 kg and your bag weighs 24 kg at check-in, you are charged for the excess 4 kg at a rate of S$25 per kg (SGD) for flights from Singapore. This applies to any fare type.
If your bag exceeds 32 kg in a single piece, Jetstar Asia will not accept it, it must be repacked into two separate bags. This rule is due to safety and handling regulations. For example, a diver’s heavy equipment bag at 35 kg would be rejected unless split. The airline does not offer a “heavy bag” option; you must purchase an additional 20 kg bag online.
Oversize bags (sports equipment, musical instruments, etc.) are accepted as checked baggage but must be declared before online check-in. A surfboard or ski bag (up to 190 cm length) costs S$60 per bag each way. Golf clubs (standard travel bag) are counted as checked baggage and subject to the same weight limits, no special sports equipment fee, but you must book the appropriate weight allowance.
Sports equipment that exceeds 190 cm in length is not accepted on Jetstar Asia flights. For flights to Australia, Golf clubs are free as part of your checked allowance, provided total weight does not exceed your pre-purchased weight.
How to Minimize Jetstar Asia Baggage Fees
Baggage fees can account for 30-50% of your total ticket cost, especially on short routes like Singapore, Penang or Singapore, Bangkok. Here are proven strategies to keep costs under control:
- Weigh your bag at home. Use a digital luggage scale. A 0.5 kg overage can cost you S$25. Scales are available at Giant Hypermarket or Decathlon for under S$15.
- Book your checked bag online during the initial booking. Adding a 20 kg bag any time before the 4-hour cut-off costs S$38; at the airport it is S$60, a 58% premium.
- Pack a collapsible duffel bag. If your return trip has more items, you can check an extra bag for S$60. A lightweight duffel weighs around 200 g.
- Wear your heavy layers. Jackets, boots, and jeans can be worn onto the plane to reduce checked weight.
- Consider upgrading your fare instead of adding bags. If you need a 20 kg bag plus seat selection, Starter Plus often costs only S$20-30 more than Starter + add-on bag, making it cheaper.
- Use a credit card with travel perks. Some Singapore-issued cards (Citi PremierMiles, DBS Altitude) include free checked baggage insurance or baggage benefits that reimburse fees, but read the terms carefully.

How Jetstar Asia Compares to Other Low-Cost Carriers from Singapore
Jetstar Asia’s baggage fees sit in the middle of the budget airline spectrum. For comparison, here is a quick fee overview for common routes from Changi Airport:
- Scoot: 20 kg checked bag online costs S$34, S$40 (depending on route). Scoot allows two cabin bags for all fares, but the carry-on weight limit is stricter (10 kg total).
- AirAsia: 20 kg checked bag from Singapore to Kuala Lumpur online costs S$28, S$32. AirAsia’s cabin bag rule allows two bags (56 x 36 x 23 cm + 40 x 30 x 10 cm) for a total of 7 kg. AirAsia is generally cheaper for short-haul checked bags.
- VietJet: 20 kg from Singapore to Ho Chi Minh City online costs approximately S$35. VietJet’s cabin allowance is only one bag (7 kg). They charge for cabin bags at the fare level.
- Cebu Pacific: 20 kg from Singapore to Manila costs around S$30, S$35 online. Cebu Pacific has a 7 kg cabin limit but allows a handbag plus a small backpack.
Jetstar Asia’s fees are on par with Scoot but slightly higher than AirAsia and Cebu Pacific for short sectors. However, Jetstar Asia often includes a 20 kg bag in promotional fares (Starter Plus), which can make the total price lower than competitors where you must add a bag separately. Always compare the all-in price, not just base fare. For a broader overview, refer to our complete guide to flying low-cost carriers from Singapore and the region.

What Happens at the Gate: Size Checker and Last-Minute Surprises
Jetstar Asia staff at Changi Airport gates (Terminal 1 and 4) use a metal sizer frame to check carry-on bags for Starter Plus and Starter Max passengers. If your bag does not fit, even by a few centimetres, you are required to check it at the gate for S$60. This fee applies even if you already paid for a checked bag. There is no warning at check-in; the gate check happens after security.
In 2024, Jetstar Asia started using a digital scale at the gate for random weight checks on carry-on bags. If your bag is over 7 kg (including wheels and handles), you must check it. The 1 kg allowance for personal items is not measured separately, but the main carry-on bag must be under the limit.
Travel tip: if your personal item is a stuffed handbag and your carry-on bag is exactly 7 kg, you are fine. But if you try to use a 6 kg backpack as a “personal item”, you may be forced to check it.
Special Items: Bikes, Dive Gear, Musical Instruments
Jetstar Asia accepts certain special items as checked baggage, but charges vary. Here is a quick reference:
- Ski equipment (skis, poles, boots in one bag): S$60 per bag each way. Must weigh ≤20 kg. If total weight exceeds 20 kg, excess weight charges apply.
- Golf clubs (bag with clubs, shoes): No special fee, treated as normal checked bag. Must not exceed 190 cm in total dimensions. Weight limit per bag (20 kg, 25 kg, etc.) applies as per your pre-purchased allowance.
- Bicycles (non-motorised): S$60 per bag each way. Must be in a hard case or box. Max 20 kg. Handlebar must be turned, pedals removed.
- Diving equipment (BCD, regulator, tank): Tanks (empty, with valve removed) accepted only if within weight limit. No special fee, counted as normal checked baggage. Must be in a separate bag. Tanks are accepted only on flights from Singapore; some destinations (e.g., Japan) may refuse.
- Musical instruments (guitar, cello, etc.): Must be in a hard case. If dimensions exceed 190 cm total, it is not accepted. For instruments up to 20 kg, no special fee. For heavier or oversized, you must purchase an additional seat or ship it.
It is highly recommended to call Jetstar Asia customer service (contact centre +65 6499 3272) at least 48 hours before departure if you plan to carry any special items. Some routes have restrictions that are not listed online.
Baggage Fee Payment Methods and Refund Policy
Baggage fees can be paid via the Manage Booking portal on jetstar.com. Accepted payment methods include Visa, Mastercard, American Express, and GrabPay (for Singapore-issued tickets). You can also pay using Jetstar vouchers, but not through third-party travel agents.
Jetstar Asia baggage fees are non-refundable under any circumstances, including flight cancellations by the airline (except for statutory refunds under Singapore’s consumer protection rules). If the airline cancels a flight and you choose a refund, the baggage fee is refunded along with the fare. If you voluntarily change your flight date, you must pay any difference in baggage fee if the new route has a higher rate. You cannot “transfer” a baggage allowance to another passenger.
Avoid buying baggage through third-party travel sites (e.g., Expedia, Agoda). In most cases, you cannot add baggage online after booking through them, you must go to the airport counter and pay the higher rate. Always book direct on jetstar.com if you plan to add bags.
Common Scenarios and What You End Up Paying
Here are three real-world examples to illustrate what a typical Jetstar Asia passenger pays for baggage from Singapore:
- Weekend getaway to Bangkok (Starter fare, no checked bag): You pack a small backpack that fits under the seat (48 x 34 x 20 cm). You pay S$0 for baggage. But if your bag exceeds that size even a little, you may be forced to check it at the gate for S$60.
- Family trip to Osaka (two adults, one child, Starter Plus fare): Each fare includes a 20 kg checked bag. You add a third bag (20 kg) online for S$78 (since the route is to Japan). Total baggage cost: S$78 (extra bag), S$0 included. If you had booked Starter fare and added three 20 kg bags, the cost would be S$114 online (S$38 each), still cheaper than upgrading to Starter Max for the whole family.
- Backpacker hopping to Bali with a 40L backpack (Starter fare): Your backpack is carry-on size (56 x 36 x 23 cm) but weighs 9 kg. You plan to check it at check-in counter. You pay S$60 (20 kg bag at airport). Alternatively, if you had added 20 kg online, you would pay S$38, saving S$22.
These examples highlight why pre-purchasing your exact weight online is the most cost-effective approach.
How to Carry Liquids and Duty-Free in Cabin Baggage
Jetstar Asia follows standard Singapore Changi Airport security rules for liquids: containers of 100 ml or less, placed in a 1-litre clear resealable bag. This applies to all cabin baggage passengers. However, duty-free liquids purchased at Changi Airport are allowed in a sealed STEB (Security Tamper-Evident Bag). If your duty-free bag cannot fit into your personal item (e.g., you already have a small handbag), you may be asked to check it at the gate for S$60. To avoid this, ensure your personal item has extra space or pack a foldable tote.
Final Recommendations
Jetstar Asia’s baggage fees are straightforward if you plan ahead. The key takeaways are:
- Always add checked baggage online at least 4 hours before departure. The airport markup is 50-80%.
- Weigh your cabin bag before leaving home. The 7 kg limit is strict; invest in a portable digital scale (S$12 at Ezbuy or Shopee).
- Consider fare upgrades if you need seat selection + bag, Starter Plus often pays for itself.
- For sports or special items, call Jetstar Asia well in advance to confirm acceptance and fees.
- If you book through a travel agent, verify that baggage can be added online post-booking. If not, factor in the airport fee.
- Compare total all-in cost with other low-cost carriers before hitting “book”. Sometimes a Scoot or AirAsia fare including a bag is cheaper than Jetstar Asia base + bag.
