The route was MAN-DXB-BKK, booked in F with the DXB-BKK downgraded to J. The downgrade was from F saver to J flex (sneaky) so I expect very little if anything but would just like a conclusion as EK said the response would be as quickly as possible.
Last year I booked this same flight in J and a few weeks before departure paid to upgrade the entire route in F, this was not a small amount so it is disappointing that I can expect very little recompense for the downgrade of one leg of the journey, but that appears to be the way with EK.
