Flying with Jetstar could soon become a little more expensive if you prefer travelling with a cabin bag. From February 2, 2027, passengers wanting to store a larger carry-on bag in the overhead lockers will need to pay an additional fee under a major overhaul of the airline’s baggage policy. Those wanting to travel with a standard cabin wheelie bag, however, will need to purchase Jetstar’s new Priority Carry-on option. The paid upgrade includes access to overhead locker space, priority boarding and a carry-on allowance of up to 10kg. Prices will vary by route, starting at around $25 on some domestic flights and climbing to as much as $52 on longer international services.
