-- Jetstar is changing its carry-on baggage model, removing its 7kg carry-on weight limit from February 2027. The move will see Jetstar shift from a strict weight limit to a simpler, size-based carry-on baggage model, similar to other leading low-fares carriers around the world. From next year, all bookings will include one underseat bag such as a backpack, handbag or laptop bag. Customers who need more carry-on baggage can pre-purchase Priority Carry-on, which includes a second, larger bag for the overhead locker and the opportunity to be among the first to board. “Our new carry-on baggage model provides more choice to customers while helping to keep our fares low.
