Very nicely laid out 'base' data .. the surprise for me was the exclusivity for the three Indian routes. But also some clear 'nice little earners' on that graphic.
Dozens of caveats, of course, the data seems to be Summer schedule (ie. CPT shown as x7 as opposed to x14 thru the Winter).
Of interest also is the cities BA choose not to serve (another nice graphic ), not many on that list I'd expect to be high up the list of priority for new routes.
