Canadian ETA
My source in T5 tells me that the Canadian ETA introduced this week is causing a lot of problems. A lot of people who seemingly received their ETA are turning up for check-in and being denied boarding because 'computer says no'.
It seems that in all the cases the problem can be traced back to something incorrect on the application. However, the problem is their ETA applications are 'provisionally accepted' online and only when their passport is swiped at check-in does it become apparent that there was a problem.
An example - UK passenger entered 'subject' instead of 'citizen'. Computer said no. Another one - EU passenger entered only 2 digits of passport number into application, which was seemingly accepted until passport swipe at check-in.
If going to Canada be warned and take great care with your ETA. Check your ETA has been 'confirmed' before travelling. And be patient with your airline as this is a problem of Canada's making, not the airlines.
