Is there any information available how many passengers on the LHR flights are actually connecting via LHR to/from another destination (and if so, to/from a destination not available at LGW). I would supsect the percentage of connecting passengers is rather low, gven the frequency of the BE flight, so that the whole exercise looks more like a vanity project. Generally, it makes a lot of sense to concentrate on high frequencies from LGW instead of spreading operations between two large London airports. If at all, a low frequency, low fare service from another London airport - such as the Aurigny service to STN - makes senses that targents a different clientele.
