Rgsaero.....Having just completed the NZ-US-UK I can honestly say that it was a breeze......The transit system has changed you walk through have a photo anf finger print and then you are out into the airside of the airport so no more hoops to jump through, have a drink/meal and then get back on board. I can honestly say that my trip both ways was easy and had no problems, I anticipated loads of waits etc but they were no longer than anywhere else in the world. No problems with any of the authorities and the people were pleasant perhaps I have that look about me that people dont want to annoy me!!!!
