As a Center controller I'd just like to say a big thank you to that JFK ground controller. Comair departs 2 minutes later and the B737 gets to go faster than a POS regional jet. We have the same setup every day coming out of BOS for DCA and I wish that the BOS ground controller would sneak the B737 past the RJ just once.
That's some interesting advice. The majority of the time we're hitting the DSP times YOUR facility is giving us! But I'll take your advice to heart nonetheless; even further, if I got a LJ60 taxiing out, I'll stop the traffic at the runway and move him right up the line to #1. Fastest traffic first, just like the .65 says??
Curious as to where you've worked ground control before...
