easyJet
EasyJet is a low-cost airline, therefore standard fares only allow passengers to check one personal item (known as a "small cabin bag") for free. Depending on your location and if you add an additional bag to your reservation, fees for normal carry-on luggage range from 5.99 to 32.99 British pounds.
Each passenger is permitted to bring one free small cabin bag on board. It must fit under the seat in front of you and have a maximum size of 45 x 36 x 20 cm (including any handles or wheels). That should be sufficient to pack everything you'll need for your trip or a short vacation. You must be able to lift and carry your own bag, which can weigh up to 15 kg. You can choose an Up Front or Extra Legroom seat or reserve a large cabin bag for your flight if you'd also want to bring a large cabin bag (max. 56 x 45 x 25 cm, including any handles or wheels), on board.
