Flybe Base
Judging by the timings Flybe are to base a Q400 at Southampton from 02/03 operating the following flights:
Edinburgh - 7 weekly
Glasgow - 7 weekly
Manchester - 12 weekly (1x Sat/Sun)
Belfast City continues 7 weekly.
Hopefully a more reliable operator for the Manchester route than Eastern (and more chances of interlining options from there?), and the Scottish routes aren't timed well for business travel, but scooping up some of the leisure and vfr market may lead to Loganair offering a few more lower fares up there. One daily flight to each is hopefully a nice boost to capacity without dumping, at least for now...
