Was downgraded today HKG-BKK from F to J due to an equipment change from a 3 class plane to a 2 class plane.

Was obviously not at all happy. Was given HK$1500 as compensation (this was an AA mileage ticket). Just wonder what people think about this. Was the compensation fair? Personally I think it is very little for a downgrade to J, but then again, it is a short flight.

FYI - F was not available on Thai (or anyone else). They offered to let me fly F the following morning but I would have to pay my own hotel - as they were offering a seat in J the day before....
