Can anyone please explain when this agreement of 50 flights, excluding London airports, comes into force over new flights from China to the UK, and vice versa, I have just noticed that Air China have said they will start an extra 3 flights per week , arriving early morning, from Beijing into LHR, There have also been a few new announcements of other airlines adding Heathrow, Hainan i think is one. Just wondering, thats all.
