British Airways is to introduce a £2.50 surcharge on each journey to pay for extra security and insurance costs following the US terror attacks.
The charge will be added to the cost of every ticket issued after November 9.
It will apply to all passengers, including children, on international and domestic flights.
BA says that since the terror attacks it has increased security around aircraft on the ground and reinforced cockpit doors.
The airline's insurance premiums have gone up "significantly".
Dale Moss, BA's director of sales worldwide says: "Safety and security is our number one priority and we hope that our passengers will understand why, in the current circumstances, we have introduced this surcharge.
"Security and insurance costs have risen throughout the airline industry and it is important that our business responds to these changes in order to maintain the highest levels of security for our passengers."
BA says more than 124 airlines around the world have introduced a security and insurance surcharge since the US attacks.
The airline carries around 40 million passengers a year.
