Good news re regional developments.
LHR-Aberdeen will be an entire bmi regional operation - all five weekday flights will be flown by Embraer 145 this summer. One off-peak weekday LHR-Manchester will also be flown by the 145; plus the LHR-Hannover stays on the ERJ as well.
It also looks as though an Embraer will spend its entire day sitting in MME between a morning flight from LHR and an evening flight back. You'd have thought that they would at least send it somewhere where it could act as back-up to the rest of the fleet, but there you go!
