Flight delays all over the globe effecting most flights


Well I noticed recently or just today as well on my flightaware aircraft alerts many airports a having big delays on departures and arrivals in and out of there countries. NZAA/YBBN/YSSY/WSSS/KLAX/KJFK/KDFW/KSFO/LHR and more are showing this. Why? I mean not every airport brings air traffic direct to there port of call from LHR even though there maybe co share flights or non at all so why is there such a big impact on the rest fo the world what has caused this drama. :smiling_imp: :imp: :angry:
