AB sends delay SMSs for a flight I never booked
 

Today I got 2 update messages about delays of AB6021 (in German). I never flown this route, I am not in the vicinity of the OD airports and I am sure I have not booked it (no reason to do that). So what is going on?

1. AB IT mess? Anybody else seeing it?
2. Someone is using my topbonus account?

Should I be worried?

Too bad AB6021 arrived less than 2 hours delayed. Perhaps, I could have claimed compensation ;)

I heard the same thing happened to a colleague. Informed via SMS about a flight he never booked. My only experience was receiving an SMS in the taxi on the way to the airport that my flight had been cancelled. When I arrived, however, the check in staff assured me my flight had not been cancelled - it was just an unfortunate mistake.

Looks like there are still a few bugs in their notification system....

I relax then :)

Or some other random passenger just made a simple typo when entering their phone number into their booking...
