I was on that cancelled flight and that resulted into an unplanned overnight stay and arrival next morning. I am a little curious on why the reason given is a weather related one? There were multiple flights that evening that flew the same / similar route at roughly the same time e.g.:
BA942 DUS
EW9469 DUS
EW465 CGN
BA916 FRA

I will file a compensation report, but seeing the WEAN code, they will (probably) deny that claim...
If I understand Flightradar correctly, the plane for BA932 was in LHR, so it can't be an inbound weather problem.

Thanks for all this information, really interesting to read!
