British Airways (BA) says it will cut prices for passengers who travel with hand-luggage only.
The airline claims travellers will see, on average, a £9 to £15 fall in prices, depending on the route. Passengers wanting to check a bag in will pay the same prices as they do now.
The move, which began yesterday, is being trialled on selected short-haul flights from Gatwick to Amsterdam, Dubrovnik, Jersey, Tunis and Turin.
BA says it plans to eventually include all its short-haul flights from Gatwick, but cannot give a date on when that will be.
The new policy will bring the airline's short-haul flights into line with budget rivals such as Ryanair and Easyjet.
Budget airlines advertise a base price without checked luggage, and passengers pay more to book checked-in baggage.
British Airways' Gatwick director Peter Simpson insists: "Those who still want to check in a bag will simply pay the same price they do now."
