In 2026, easyJet is extremely strict with hand luggage dimensions, as their business model relies heavily on ancillary fees. Every passenger is allowed one "small cabin bag" (45 x 36 x 20 cm) for free, but it must fit under the seat. A supportive peer "airport" alert: ground staff frequently use metal sizers at the gate, and if your bag’s wheels or handles stick out even slightly, you will be charged an "oversize" fee of roughly $45–$60 (£37–£48) to have it placed in the hold. If you want a "large cabin bag" (56 x 45 x 25 cm) for the overhead bin, you must pay for it in advance or book a "Standard Plus" or "FLEXI" fare. In 2026, easyJet's gate technology has improved, with some airports using automated scanners that flag oversized bags before you even reach the boarding agent, so measuring your bag at home is non-negotiable.
