FWIW I've just starting to hear
rumours of thunderstorms causing lots of disruption to flights inbound/outbound from some of the SE UK airports this evening. I'd emphasis that is a rumour but if it
is a problem perhaps thats what is causing issues at LCY?
Anyone know more?
Edit to add: Re specifically the thunderstorm rumours - here you go, just seen this, timed at 2030 UTC, on the Eurocontrol Network Ops portal:
Significant Weather Affecting EGTT South sectors: Lydd, Clacton, Dover and Hurn. All these sectors are regulated at drastically reduced rates, with delays exceeding 150' till 0300 UTC tomorrow morning.
Same situation for East sector in terminal area.
This an evolving situation with further measures in Southern UK being introduced. Improvements in the near term are unlikely.
...and 'cos I'm really bored I've also had a quick look at Flight radar and it shows the BA8474 on approach to LCY as I type but arriving about 2 hours late...
