Jetstar Baggage Size Guide for Domestic and International Flights

Jetstar allows one main carry-on bag up to 56 × 36 × 23 cm plus a small personal item that fits under the seat. Checked baggage must have no side longer than 1 metre, and each individual bag cannot weigh more than 32 kg. Passengers can purchase up to 40 kg total checked baggage per person.

This guide explains Jetstar luggage size rules and how common suitcase sizes used in Australia fit the airline’s domestic and international baggage requirements.

What Size Suitcase Is Allowed on Jetstar?

Jetstar allows the following luggage sizes:

• Carry-on suitcase: up to 56 × 36 × 23 cm (including wheels and handles)

• Small personal item: must fit under the seat in front of you

• Checked baggage: suitcase with no side longer than 1 metre

• Oversized baggage: any bag with one side longer than 100 cm
  

Jetstar Carry-On and Checked Baggage Rules

Jetstar controls luggage by both size and weight, and baggage allowances depend on the fare you purchase.

Carry-On Allowances

• Passengers may bring two cabin items:

• 1 main carry-on bag

• 1 small personal item

• Maximum carry-on size: 56 × 36 × 23 cm

• The personal item must fit under the seat.

• Economy fares typically include 7 kg or 14 kg of carry-on weight.

• Business fares include 14 kg of carry-on.

• If you have a 14 kg allowance, no single carry-on item can exceed 10 kg.

Jetstar may weigh carry-on luggage at the airport. If your bag exceeds the allowance, it may need to be checked and additional fees may apply.

Checked Baggage Rules

Jetstar manages checked baggage primarily by total weight allowance rather than number of bags.

If you purchase 35-40 kg, the weight must be split across multiple bags because a single bag cannot exceed 32 kg.

Many Jetstar fares do not include checked baggage, so adding baggage when booking is usually cheaper than paying at the airport.

What Size Suitcase Should You Use for Jetstar?

Choosing the right suitcase size depends mainly on trip length.

Choosing the Right Jetstar Suitcase Size

Below is a simple guide to common suitcase sizes in Australia and how they align with Jetstar baggage rules.

Choosing luggage that fits Jetstar’s size limits makes travel easier and helps avoid excess baggage fees.

Travellers looking for a compact personal item can explore our Under Seat Luggage collection designed to fit neatly beneath the aircraft seat.

For short trips or light packers, a Carry-On Suitcase or Lightweight Carry-On is ideal for Jetstar’s cabin size limit of 56 × 36 × 23 cm.

If you need more packing space, Medium Suitcases or Medium Lightweight Suitcases are a popular option for week-long trips while still staying comfortably under Jetstar’s oversized baggage threshold.

For longer holidays, travellers often choose Large Suitcases or Large Lightweight Suitcases, which offer extra packing capacity while remaining within standard airline luggage size limits.

For extended travel or family packing, Extra Large Suitcases provide maximum storage while still staying under Jetstar’s 1-metre oversized luggage rule.

Suitcase Weight: Why Lightweight Luggage Matters

When choosing a suitcase, the weight of the bag itself is just as important as its size. Jetstar baggage allowances include the total weight of the suitcase and everything inside it.

Choosing a lightweight suitcase allows you to pack more without exceeding airline limits.

How to measure your suitcase for Jetstar

To measure your luggage correctly:

1. Measure the height, width, and depth of the suitcase.

2. Include wheels, handles, and external pockets in the measurement.

3. Check that no side exceeds 1 metre for checked baggage.

4. Weigh the packed suitcase to ensure it remains under 32 kg per bag.

Many airlines, including Jetstar, measure luggage using the outer dimensions of the packed bag.

Tips to avoid Jetstar baggage fees

To avoid unexpected luggage charges:

• Choose a lightweight suitcase so more of your weight allowance can be used for packing.

• Weigh your bag at home before leaving for the airport.

• Keep liquids, electronics, and essentials in your carry-on bag.

• Purchase checked baggage when booking your flight, as airport fees are usually higher.

FAQs Jetstar Baggage Rules

Do Jetstar measurements include wheels and handles?

Yes. Jetstar’s carry-on size limit of 56 × 36 × 23 cm includes wheels and handles, and the same applies when measuring checked baggage for oversized limits.

How does Jetstar treat carry-on weight across multiple items?

Jetstar allows two carry-on items, and the total weight allowance is shared across both items.

What is a safe size for a Jetstar under-seat bag?

Jetstar does not publish exact dimensions for under-seat luggage. A safe guideline is a compact bag around 40 × 30 × 15 cm that fits comfortably under the seat.

How do you know if your suitcase is oversized?

Measure the longest side of your packed bag including wheels and handles. If any side exceeds 1 metre, the bag is considered oversized.

Can you split Jetstar checked baggage across multiple bags?

Yes. Jetstar uses a combined weight system, meaning you can distribute your total allowance across multiple suitcases as long as each bag stays under 32 kg. 

Choosing the Right Suitcase for Jetstar Travel

Choosing the right suitcase comes down to understanding the airline’s size and weight limits. Carry-on luggage must fit within 56 × 36 × 23 cm, while checked bags must remain under 1 metre on any side and under 32 kg per bag. By selecting a suitcase that fits these guidelines and suits the length of your trip, you can pack more efficiently, avoid excess baggage fees, and travel with confidence.
