If EK go with a 3-class on all three flights the actual increase in capacity is lower than one would first think.
Currently:
EK (1xA380 + 1x77W) = 1026 + 852 = 1878
QR (1xA333) = 610
EY (1x77W) = 756
Total = 3244 per day
Prospective:
EK (2xA380 + 1x77W) = 2052 + 716 = 2768
QR (2xA332) = 1088
EY (2xA332) = 1048
Total = 4904
Increase = 1660 or 51.1%
That is on the understanding that Emirates go all F and Qatar/Etihad do not. If they do, it will be a lower seat increase but then again they still have to sell a significant number of J/F class seats.
Still a large increase but not as much as expected.

I'm sure I heard that for the airlines to operate most effectively they aim for around 85-90% load factor on average. That way they're satisfying demand and not losing business. I may be wrong but I guess that with all three carriers struggling to meet demand, not just at MAN but across the globe, MAN should feel quite honoured that they're all focusing on this airfield as opposed to others anywhere in the world.
