People who travel a lot fly with BA because they know they will get what they want and what they need. First of all, they want to go safely, and they also want to go quickly, across the country, across the sea, or right across the world — and they know BA will take them where they want to go, when they want to go. BA flies all the newest and fastest planes, to more towns and cities, in more countries of the world, than any other airline.

Do you want to go to Paris, Washington, or Beijing? BA will take you there, at all time of the day and night, right through the week. BA flies not only to the big cities, we also fly three or four times a week to towns and cities in the very heart of Asia, Africa and South America.

People who travel a lot fly with BA, because they know that they will leave on time, and arrive on time. They know the food they will receive and the films they will watch will be of the very best.

BA should be considered second to none. When you fly, fly with BA.
