Passengers flying to the US must apply for permission to enter the country three days before their date of departure under new border regulations implemented last week.
It will now be compulsory for airlines to comply with the Electronic System for Travel Authorisation (Esta), which was introduced by the US government and comes into effect on January 12th.
Speaking to travelmole.com, BA government and industry affairs manager Jim Forster said that BA would be inviting its customers to apply for Esta.
"We have been working hard to ensure that visa waiver customers are aware that they must apply to the Department of Homeland Security at least 72 hours in advance of travel," he told the website.
The new legislation means that all incoming passengers to the US will have to provide their name, date of birth and passport details – as well as their flight number and intended destination address.
More people are booking flights to the US following Barack Obama’s presidential election victory, according to new figures from adventure tour operator Intrepid Travel.
