There are 4 domestic routes into LHR on which BA and BMI compete. The CAA reported that passenger numbers in 2000 were as follows:
EDI 1.6m
GLA 1.4m
MAN 1.2m
BFS 1.1m
Arguebly the mainland routes were boosted in Q4 2000 by the debacle with the railways post-Hatfield.
Without information on capacity and yields it is diffilcult to draw too many conclusions. However at face value there appears to be a tremendous difference between the yields at MAN and BFS if MAN is profitable and BFS has lost £38m over the last few years??
