EasyJet customers who want to use overhead luggage lockers will have to buy more expensive tickets.
Under the new policy, passengers who want to travel with an additional large bag as hand luggage must pay an extra fee, which will also enable them to select a seat either near the front of the plane or with extra legroom.
easyJet said this would be available from £7.99 but ranges in price to up to £24 each way.
The Luton-based airline claimed the move would “improve boarding and punctuality”.
easyJet chief commercial and customer officer, Robert Carey, said: “Punctuality is important to our customers and we know that, if they have their bags placed into the hold at the gate due to the limited space onboard, this can cause flight delays and it can be frustrating for them too.
