I travelled out on 12 Jan, the date this went fully live. All passengers on the aeroplane were aware of it and had done the necessary. The cabin crew were aware of it. When we arrived at Philly, the line organisers or whatever they are called were telling everyone to ensure they'd filled in a white or green form.
'But we've all got them done already', we chorused, as if it would make any difference.
Upshot was that by filing on-line initially, the process took three times as long as eveyone had to pause to write out a form at Immigration, then proceed for the initial inspection and get fingerprinted etc. as before.
I hope the systems have improved since.
This has to be a stupid question, but I'm curious why fingerprints must be taken every time one immigrates; surely once logged that's sufficient for future arrivals or have I missed something really obvious?
I seek to learn....
Edited to add this is ChampChump borrowing WKW's ID. Maybe I should try this at Immigration....
