Read about our new cabin bag guarantee for travel from 2 July.
Overhead locker space on board our aircraft is limited, which means on busy flights we’re not always able to fit everyone’s cabin bag on board. So to make things fair, we’re introducing a cabin bag guarantee from 2 July.
From 2 July, if you bring ONE piece of cabin baggage no bigger than 50 x40 x 20cm including handles and wheels, we guarantee it will always travel with you either in the overhead locker, or if necessary, under the seat in front of you.
You can still choose to bring ONE slightly bigger bag up to the maximum size of 56 x 45 x 25cm including handles and wheels, but on some busy flights your bag may have to go into the hold.
Or, if you’re an easyJet plus cardholder, FLEXI fare, easyJet plus Upfront or Extra Legroom passenger:
You’re allowed ONE piece of cabin baggage no bigger than 56 x 45 x 25cm including handles and wheels. Overhead locker space is limited so please use easyJet plus Speedy Boarding to board first in order to secure space in the overhead lockers.
PLEASE NOTE THAT THE NEW CABIN BAG GUARANTEE ONLY APPLIES FROM 2 JULY 2013.
