Our flight BA937 DUS-LHR for this morning 22-12 got cancelled last night. Does anybody have any idea as to why this was?
I checked experflyer, but I am not sure where to look for the code:

I kind of assume it was because of storm PIA, but we are the only BA flight cancelled today out of DUS, so seems a bit weird.
The booking was made through AA and we got rebooked a day later on saturday 23-12 (BA937 DUS-LHR and BA289 LHR-PHX) because we have a connecting flight to Phoenix.
There were no other options available on the 22nd.
