I don’t think anyone covered themselves in glory with this episode. NY atc do a pretty good job with incredibly busy airspace.
As a general comment (from a Nigel) ATC in the states generally have procedures that work for local carriers but are mainly aimed at helping ATC first and foremost and have scant regard to the end user ie pilots. I’ve just learned to adapt and cope. I agree the issue could have been dealt with a simple “unable, 180 to 6 is the best we can do”. The extra stuff about what aircraft he was flying wasn’t really necessary. It’s a stressful business flying in and out of NY airspace for all concerned and sometimes this sort of stuff happens. As long we all keep it safe, so be it.
