Amsterdam
The backing out of the SOU/AMS probably had something to do with Scotairways applying for slots for an EDI/LBA which is a very lucrative route for BMI there are never any cheap fares on it.
If I remember correctly slots had been applied for EDI & MAN/SOU for the summer timetable and given some of the OTP & crewing issues BE have at the moment, BMI may think the time is right.
I am not sure about MAN/SOU but average fares on EDI/SOU have risen sharply since BE had the route to itself.
