At JFK last night I watched the VS4 leave the gate more or less on time. There were terrible airfield delays because of poor weather -- we were told to expect 90 minutes of taxiing. I was on the 46 and we pushed back on schedule and then had a long wait in the queue of departing aircraft.
As we took off, we raced past another VS aircraft which was queueing to take off. It can only have been the 4 but it seems odd that we would or could have overtaken it -- after all, it left the gate an hour before us and must therefore have been taxiing for around 2 hours! I see that it did indeed land at LHR 30 minutes after the 46.
I assumed that aircraft would be allocated takeoff slots roughly in order from when they departed from the gate. Is this incorrect, or did something else happen to delay that flight?
