I never did a positioning flight (combined tickets yes) until now. Flew 805 / 806 today and combine it with AY9.
Yesterday evening OLCI didn't work, only for the first leg. I used the chat and they said that randomly 3 J passengers and some Y passengers are selected for US bound flights to go to an agent.
However, this morning 2h before AY805 I received SMS with both boarding passes.
Still I went to the checkin in Helsinki and got the boarding pass for AY9.
