Flybe seem to be short of one rotation per day at Exeter to make everything fit. The EXT-NCL is non-op on Mondays this summer, EXT-BHD on Tue&Fri, EXT-DUB on Wed&Thu. It's a bit random, but that's what they look to have done, so I would draw some comfort re EXT-NCL that it's only lost one weekly frequency instead of the two chopped from the longer-established BHD and DUB routes!!
