Lots of flight delays at LHR this afternoon [17 Mar]
We are in T5C waiting on more information on our delayed flight to SFO. It is not that the incoming flight was late, as the plane has been here since arriving from South Africa this morning.
Over the past hour have been many announcements regarding delayed flights, not just to the US, but Athens, Mumbai, and other places. Any idea what might be the cause? It should not be weather-related in so many diverse places. Maybe crew shortages?
