EasyJet has tightened its rules on cabin baggage, with passengers told they can only be sure of carrying their bag on board if it is no bigger than 50cm x 40cm x 20cm.
While the new size restriction comes into play on from Tuesday, the old one of 56cm x 45cm x 25cm remains. However, full flights could see passengers at the back of the queue with big bags forced to check them in.
EasyJet said: "If you bring one piece of cabin baggage no bigger than 50cm x 40cm 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 56cm x 45cm x 25cm including handles and wheels, but on some busy flights your bag may have to go into the hold."
The budget airline added that the bag guarantee has been introduced so passengers know their bag will definitely be with them in the cabin. It said the new rules are clear and fair to all customers, having been based on feedback.
The results of a Which? magazine poll show two in five easyJet passengers will take a chance and continue to travel with a bag close to 56cm x 45cm x 25cm.
Meanwhile, British Airways passengers can now use their mobile phones the minute they land at their destination.
Until Tuesday, BA customers could only use mobiles and other electronic devices when the plane was stationary and the doors had opened.
The airline will continue to enforce rules which prevent passengers from using electronic devices once the plane has started taxiing.
