As I have read, travelers with passports from the U.S., Canada, Australia, New Zealand, or Japan will soon be able to "jump the queue" on arrival at London Heathrow, using electronic passport gates previously reserved for EU passport holders.
Per what I read, “It's big news for several reasons: Waits for passport processing at London Heathrow have recently been very long for visitors from outside the EU. The new measure is expected to speed up the process in a big way. (At an electronic passport gate, all you have to do is place your passport on a scanner and pause for a photo that's cross-referenced with your document. Once the system matches the scans, a gate will open and you're free to go.) It's also part of the U.K.’s bigger plan to appeal to other non-European countries—and their respective travelers—as it readies itself for Brexit.”
This perk isn't expected to start until mid-2019. Observations and comments, please.
