Panpanpanpan,
Mystifying it is, but as you have indicated in the past both airports are profitable and sustainable in their own rite so no need for any concern here them irrespective of what potentially BFS employees say...
Concerns me what sardonic is saying as is like the green birds to hang about.

Though I'd suggest there are opportunities for efficiencies as load factors not huge on LHR. On a cost efficiency basis Panpanpanpan 's suggestion of EI being on the bhd side and BA doing reciprocal service with no night stop has merit...
