Stand 12 has just two jetways .
Not ideal for this two class airframe actually.
Read Birmingham may be fitting out a three bridge gate and that's certainly a much superior arrangement for handling the two class airframes.
As more frames become available I think EK19/20 may well revert to the three class frame later in the spring with the morning flight moving to the two class 388 - Estimate June 2016 or there about.
After that the fourth flight will be introduced with a mid afternoon 77W coming on stream - a la EK29/30 at Heathrow mainly for freight but using a two class machine.
All conjecture but with reasoned argument.
With four flights Emirates may move their focus elsewhere for growth and for some considerable time there after.
