Let's see what happens at 9pm. That is the moment of truth the FT mentioned earlier today.
From what I understand, three flights have been outright cancelled so far (GLA-BHD/BHX; LHR-ABZ) and two diverted (BHX-EDI/GLA - which will result in further cancellations). a number of inbound flights in the air. Are there any departures scheduled after 8:30 pm on a regular wednesday? If so, it might be worth checking their status.
