hello! I'm fairly new and have never claimed a compensation so I was wondering if in this case it's worth claiming one.
I was booked on BA12 SIN to LHR on 9.10.2019. Scheduled arrival at 5:50am, connecting flight BA964 departing at 7:10am and arrival time 9:45am in HAM.
BA12 arrived late so I was automatically rebooked onto BA964, departing 10:40 and arriving at 13:20pm in HAM.
This leaves me with a total delay of 3:30h which I think leads to a compensation of 300€?
But the thing is, I don't know what caused the delay, since I was sleeping and didn't pay attention to the PA very much. When arriving at the airport I was immediately given my new Boarding pass.
Is there any way to find out what caused the delay? Thank you!
