easyJet does allow "big bags," but their definition and pricing have become increasingly segmented in 2026. Every passenger is allowed one small cabin bag (maximum 45 x 36 x 20 cm) for free, which must fit under the seat in front of them. If you wish to bring a "large cabin bag" (up to 56 x 45 x 25 cm) to put in the overhead locker, you must either book a "Standard Plus" or "FLEXI" fare, or pay an additional fee to add the bag to your booking. For even larger items, easyJet offers checked-in hold luggage in three weight categories: 15kg, 23kg, and 32kg. A 32kg bag is the maximum "standard" size allowed for safety reasons. If your bag exceeds the dimensions or weight you have paid for, the airline will charge significant "excess baggage" fees at the airport. It is always much cheaper to book your large bags online in advance rather than at the check-in desk. For those traveling with sports equipment or musical instruments, easyJet has specific "large item" categories that can be added to the reservation, ensuring that even "big" gear can be transported provided the appropriate fees are settled.
