I have to agree with most posts... no compensation for 2 hr delay. Just write to them and hope for the best. I wrote to complain and to comment about my recent Asian flights last month... lo and behold, I got 19.5K miles (11.5K miles outbound for DTW-NRT delayed flight, and 8K miles for SIN-NRT flight).

The DTW-NRT flight was a poor judgement call by the pilot - he should have had the sick passenger removed instead of being treated on board... that was just at the start of a 12.5hr flight! The return flight was annoying b'cos they op-up'd me but not the rest of my party (my sister and kids). I switched with sis and sat in the back with the kids. Unfortunately, the seat was broken -- no recline and no AVOD.

Moral of the story... put it in writing.
