I was wondering. I was tracking flights departing from JFK, one in particular AA177 on March 2. I looked at aa.com and it stated that it had an actual departure time of 7:59 but yet it didn't show up on flightaware until it had its wheels up time of about 9:23pm. So it departed the gate about 8 and didn't leave the ground for another 90 mins. Is this a typical taxi time for JFK because of all of the European bank of flights or was it weather related? And if it was because of the high bank of European flights is there a more ideal time to depart where you can have say a 10 minute max taxi time from gate to wheels up, where you are not in a line of 20 planes waiting to take off?
Also heard from my aviation law professor that JetBlue has a dedicated runway for them to use (weather permitting of course) that allows them to get up into the air quicker than other carriers. Then runway he mentioned was the one right by their terminal but couldn't remember the number. Is there any truth to this claim?
