I flew on the first EK22 out of MAN at the start of May. They use the old A330s on this route, so old style seats (no lie flats in J and no suites in F) and the ancient IFE (no VOD). If you're used to the 777 or 380 hardware you may be disappointed.
That said, the flight times are great if you want to get into DXB at a civilised hour and the airport is deserted upon arrival. It took only 25 mins wheels down to being in a cab and on our way home. Also, the lounge at MAN was very quiet compared to the pre-A380 crowds. IMO a great flight for Dubai residents or visitors, but may not offer the short connection times of the later flights arriving 12-1am
FWIW I'd say the plane that day was about 60% in Y and J.
