Please calm down everyone.
MST and ANR have been dropped presumably because there was no prospect of either becoming profitable in the foreseeable future. The routes to CFR, GRQ, FMO and RNS have all shown potential and are certainly worth another summer season to prove themselves. SEN-RNS has never been on sale for S15; it was a glitch on the website that meant the summer months were shown but with no flights loaded. Wait a few days and I expect we shall see the S15 timetables appear for the four remaining routes, as well as whether or not Stobart Air will add to the existing DUB-SEN Flybe 'mainline' S15 timetable.
For two routes out of six launched simultaneously to have failed to meet expectations is nothing new in this industry. Who knows how many of the recently launched LCY routes by Flybe itself may also fall by the wayside?
