HI all
On 30 May 2014, all operations ceased at the old Doha International Airport (OTBD) and moved to the new Doha Hamad International Airport which has been built to the east of the old airport.
I've just added OTHH to the databases and updated all flights from OTBD to OTHH. The IATA code remains unchanged as DOH.

There is some ok looking freeware scenery for OTHH on Avsim.
