I think the information will be taken well before arrival at the airport.
I take the Daily Mail, because of the racing page.Im not Right Wing ,nor play on the Left Wing. Im usaully in the defence. Like all newspapers its only 10% Fact,and that includes the Crossword. Apparently 72% who voted on the Mail Poll,agreed with the idea,mind you can you believe the Mail.
Anyway for me anything that makes travel safer is OK.
It just makes me smile a little,when for example we recently returned from Lisbon,to Liverpool passing through Passport control takes some time,even with the one flight.It does however give you time to read the signs telling how it is neccesssary (I agree) to attempt to stem the flow of Illegal Entries to the country. According to the Mail that was around 500,000 last year. It aint working.
Of course the Daily Mail may have made that UP
Im still booking for Kalami next May. However many questions
