Legs or not, to be quite honest and not intending any punt against our colleagues at FD, the actual situation at DXB would rather need the 737s and 320s be sent to Sahrjah or Makhtoum.
The whale already slows down the hourly frequency of dep/ldg with the increased separation, so the light twins, with another minute more, are even more anachronistic in the screwed up layout of DXB.
If it is inevitable that FD stays at DXB, every logic would point out to a Makhtoum ops but logic is the big absent in UAE aviation, then a switch to 757/787/330 would be more than welcome.
