This all seems rather bizarre, why stop Saudia Pilots training to fly MD90s used on internal Saudi and regional routes when they are already (and have done for many, many years) training their own crews in Jeddah on B747s that actually fly to The US?
The only reason they are not already training their own MD90 crews is that it took them years to stop internal squabbling and decide on a final site for the new Saudia training centre! It should be up and running soon.
All seems very silly to me, but then, what do I know!
