Snow

I was just looking at FlightRadar24 and noticed that LHR is still busy with departures and it’s 2:10am!
I assume the snow is causing some delays.
However one of the flights that has just departed is BA1338 (SHT12T) G-EUXI enroute to Newcastle. Seems abit of an odd flight to be doing at this time of night as I thought they would of been focused on getting the long hauls out.
