Hi Duncan,
Yours is the first positive comment I have heard for ages about LAX, perhaps you were lucky. Also you have to get a transit visa and it now costs to go through.
"British travellers to the US under the Visa Waiver Programme (VWP), which allows most British Citizen passport holders to visit for up to 90 days without a visa, must get an authorisation via the Electronic System for Travel Authorisation (ESTA) prior to their journey.
Visitors should register through the ESTA website at esta.cbp.dhs.gov and are advised to do so at least 72 hours prior to travel. If you do not have an ESTA you will be refused travel to the USA. The US Customs and Border Protection department began charging $14 per application for an ESTA on 8 September 2010. All payments must be made by credit card."
Too late now I booked NZ Air via Shanghai Pudhong for the 21st October now -
what's the betting horror stories about this route will emerge now. he he he
