It is a shame here is no serious competition from a legacy carrier. If Little Red had been more successful here would at least be competition on the AngloScottish routes and that might have kept BA on their toes in terms of FFP offerings (and pricing - BA's prices LHR-EDI and GLA are so much more than they were when BD also flew the route).
I feel like giving up on BA, and that's flying into/out of London. if I lived elsewhere in the UK I would probably be looking at what direct flights were available for SH and connections via hums other than LHR for LH.
