Currently all flights to the US are facing conducted added security provisions at the airport and during the flight. To avoid delays flight passengers to the US are strongly advised to arrive early at the airport, as well as to check in as many pieces of luggage as possible in order to reduce hand luggage to a minimum.

Also, on 20th January 2010 it became mandatory for all British passengers travelling/transiting to the United States under the Visa Waiver Programme (VWP) to apply for an Electronic System for Travel Authorisation (ESTA) 72 hours prior to departure. This online form will eventually replace the green visa waiver form (I94W) which is currently completed whilst en-route to the US. Passengers should visit the website: https://esta.cbp.dhs.gov and fill in the required information. In most cases a response will be received within seconds determining whether travel to the US has been authorised. If the application is not authorised then a visa may be requested through the US Embassy. In some instances customers will need to wait up to 72 hours for authorisation.
