A budget airline is to charge passengers an extra fee for putting a second bag in aircraft holds.
Easyjet said the increased security measures at UK airports was to blame for the move.
It will cost passengers £10 to put additional luggage in the hold on check-in or £5 if paid in advance.
Spokesman Toby Nicholl said: "We've seen in the past three weeks an explosion in the amount of baggage put in holds and it is delaying check-ins."
He added: "We're trying to incentivise passengers to take one bag to reduce delays."
