Since I was one of the people wondering why flights are not cancelled much and attempts are made to land in bad weather and often divert, I've just read this on my news feed from the Irish Times newspaper about Dublin Airport. Sorry can't link I'm not on the same device. Anyway it's paywalled.
" 7pm update. So far today airlines have cancelled a total of 114 flights, 58 incoming and 56 departing. 36 flights have diverted to other airports with 27 go arounds."
