Here's an idea that AirNoServices and his mates at UAE could use to justify their pay rise.
If they get a sudden rush on in the morning then why not stick a few random aircraft into the DESDI hold at say FL170-200 and then route several following aircraft under DESDI at 10,000-13000" for a straight in at DXB.
When things quieten down a bit bring off the DESDI holders so they land 10 minutes after aircraft that they had previously been 10 minutes ahead of when they were with Bahrain.
Must be worth 2.5%.
