If you fly out of Nice at least ten times a year, request a “Premier” card which gives you access to the dedicated rapid security checks at T1 or T2. No more queuing for security thanks to this fast-track initiative by Nice airport Marketing Director Filipe Soete.

And flying into London, IRIS scan recognition has been abandoned in favour of a much better system at Heathrow, Gatwick and Luton. Available only to EU passport holders over 18 and with new chipped passports (which have this image on the cover) you just enter the “e-passport” booth, put your passport into a scanner which compares your face with the passport photo and opens a gate allowing you into the UK without even dealing with a real person. It works perfectly.
