Although Emirates advertised to travel agents in South Africa that ALL its Business Class seats were "lie flat" ones, the EK765/EK766 flights are NOT - even though EK766 is the late night (overnight) flight from Johannesburg. They use an Airbus 340 with reclining seats, so no sleep possible! When I complained to Emirates they tried to pass this off initially as an aircraft change. When I pointed out this was not a change of aircraft (after doing some investigation), they were largely uncaring. Their attitude seems to be that they are the only airline flying directly between Johannesburg and Dubai, so we have to use them. Not a good response from the airline. Attitude very poor (and made worse as I am a Gold Skywards member, although seriously considering a switch to Etihad now).
