Sunday 1 September

I will give a full list later today, but there are a lot of cancellations out of LHR today - around 20 departures and the same arrivals so far. Now I suspect it's HADACAB in play due to cumulonimbus activity, as reported on the news, but I haven't seen the evidence of this and the cancelled flights are not yet marked as weather related. I will do the usual list in due course, but can I invite queries relating to LHR - inbound and outbound - just to hold off for the rest of today please, as per the text in post 1. The information will appear here in due course. LCY and LGW are different, ask away!

The longhauls - which won't be weather or ATC are BA207 MIA and BA169 PVG.
