posted today on LinkedIn by an agency who tracks fares by route and mixes the revenue with costs published in airline accounts.
Most of these routes have been culled or suspended but LGW and FCO remain according to the post.
Would be interesting to see the same analysis network wide which, given they are keeping LGW and FCO at -29% and -22% margin respectively will likely show that there aren't too many 'profitable' routes that they can focus on.....
