No worries Porter, Im always honest
In terms of time, worst delay airborne was the UAE, issued an EAT for 2hrs and 50 minutes after our scheduled arrival at the holding fix, apparently due to Fog and the fact that the airport had just reopened after the supposed 100% backup electrical system for the airfield failed
On the ground, JFK, number 90-ish for departure, the controller would issue "all aircraft on taxiway xx...gentlemen start your engines!"
Enroute, into LHR, slowed down, vectored then held at biggin for about 40 minutes, again due to LVP's
For pure pain in the arse, and I started a thread about it, ANY late notification of a delay into an Oz airport when you aren't expecting it
The US, EU, UK do a great job of sharing info and passing delays on, in the UAE I expect a minimum of 20 minutes, in Oz...nobody knows from one day to next
