The Polar hangar is empty most of the time. Recently two pairs of RAF Tucanos on consecutive nights, and occasionally an overflow Ryanair 737.
30 to 40 staff from the Polar hangar joined the Ryanair hangar when the former closed, I believe. That manned up the 2nd Ryanair bay, and with the tail sticking out, a 3rd 737 can be worked on ''inside'' the Ryanair hangar. At this time of year there's often a 737 parked outside all day.
I'd be surprised if there was to be a substantial increase in jobs, Mr MOL has / had a dispute with the local council about rates, so the 2nd, 3rd, and 4th Ryanair hangars up to the tower didn't happen. You would think instead that the Polar hangar would be ideal for Ryanair location wise.
