British Airways is to allow passengers to provide additional US immigration details in advance online in a bid to reduce delays on arrival.
From 4 October the airline will allow passengers to enter details about country of residence and address for their first night's stay on its website.
This is in addition to the Passenger Name Record information already provided by the airline to the US authorities before take-off, which includes personal and passport data.
Simon Parks Smith, head of product management at BA, said: "Every customer can use 'Manage My Booking' on www.ba.com to enter their Advance Passenger Information [API] details, even if they haven't bought their ticket online.
"We have also put a comprehensive section about API on our website to help answer customers' questions."
Under American law, the US Customs and Border Protection will receive certain travel and reservation information, known as Passenger Name Record data, about passengers flying between the European Union and the US.
This is retained for three years and six months and may be shared with other authorities.
