That was nonsense, since the CI worked without problem, without need to scan the passport, with the airport check-in machine.

I did, however, complain to the travel agent afterwards, who replied that there was nothing wrong with the booking... and indeed, I had booked several Blue1 flights around the same time, at the same online TA, and none of the other ones had any check-in problems.

On the other hand, I've also got a general OLCI error message in the past, and only at the airport did it tun out that the flight was actually cancelled.
