It does smack of unfair rules.
I know Paul Kehoe went apocalyptic when he thought MAN had received £12m to get Hainan in, but that was a range of tourism activities about promoting the whole of the north and north west to the Chinese audience, it was never ever £12m singularly for the Hainan airlines route.
This BFS fund seems to be directly funding the UA route, which, under scrutiny may be illegal and could be challenged, but of course, we cannot jump to those conclusions just yet as we don't know the full details.
If people had believed Paul Kehoe about Manchester then it could have been the start of something bad, so it's only fair I afford BFS the same courtesy.
