FYI i have about 180,000 miles in my account (currently silver) and i suffered a delay of just 45 minutes ( i think) from MAN due to an issue with the airport staff and not QR. The result was i missed my connection and had to get another flight to a different city some 7 hours later... I paid for my own taxi when i landed, they did offer me the bus...

Anyway, i got 10k as their first offer - i asked for more, but i only got this many - which from memory is the same amount i got with another flight which was delayed (at gold status)...

I am sure you can get some more out of them, if they are any use - is a different matter... BTW remember you can fly HAN>BKK with QR to use your miles...
