Jet2 Cabin Bag Size 2026: What Fits and What's Free

Jet2 is more generous than the budget airlines, giving you two bags as standard. Here is what you get in 2026.

Jet2's bag allowance

• Free underseat bag: 40 x 30 x 20 cm, fits under the seat.
• Cabin bag: 56 x 45 x 25 cm, up to 10kg, in the overhead locker. Included on standard fares, which is why Jet2 is popular with families.

What fits?

Because the Jet2 cabin bag is a full 56 x 45 x 25 cm, almost any travel backpack fits. Our Vacuum Compression Pack (49 x 32 x 15 cm, opening to 20 cm) goes in with room to spare, and its built in pump compresses a week of clothes into the cabin bag so you can skip the hold entirely.

The weight limit is the catch

Size is easy on Jet2, but the 10kg cabin limit is where people get caught. Compressing clothes lets you carry more without adding bulk, though weight still counts, so pack heavy items sparingly.
