Actually, AB re-booked me during the night on another airline, avoiding TXL tonight altogether. I got a faster direct connection about the same time. They did it automatically, I just got a check in invitation from another airline by email. I did not even have to go to the airport and live through all the mess and stress there. I am (again) impressed by their IRROPS service, unlike most people here. I am not sure why they always treat me so well. Perhaps, things work differently at the CPH station?
Anyway, praise is due where it's worth it: excellent handling from AB.
