I had a disappointing boarding experience today, HEL-ZRH. While waiting for Group 3 to be able to board, I saw one of the gate agents forcing everyone to show their Covid test results and the QR Code to enter Switzerland, which resulted in a very lengthy boarding process. I assume she didn't care whether it was printed CDOK on the boarding passes, as everyone had to show it. The Norra flight was about 70-80% full.
Luckily the 2nd gate agent trusted the CDOK print and I went for that lane
If they will continue with this process during the summer holidays, good luck with on-time boarding...
