EMA-ABZ certainly has been reduced from 4 rotations to 3, whether that is because of falling pax/yields I'm not sure. Would be surprised if they dropped it further to 2, but at some point I do feel EMA-ABZ could become a loco route, I would say bmi Baby may fancy a crack at it. If/when that happens, T3 may not think it worth continuing.
Similarly LBA-ABZ especially now with Flybe for company could see changes in future but for now T3 continue with 3 rotations M-F.
However T3 will certainly I feel put up a fight on ABZ routes down the east coast - lots of lovely high yield oil business traffic, which is where EMA/LBA perhaps differ.
