It was very interesting.
I don't know what plan they filed originally, but once they reached cruise alt. they requested a direct clearance to some point (which I've forgotten, unfortunately).
I heard a lot of chatter from other airline flights as well... altitude and route requests that seemed more spontaneous than I'd expected, almost like for GA IFR flights. There seemed to be a layer of turbulence that westbound(?) flights were eager to avoid... one such flight was told to just stick with their clearance; the controller could not accommodate them (probably due to traffic). Next time your flight gets bumpy, remember that.

The crew on my flight didn't talk to anyone for a long time, then after being cleared to descend, they were given (quite a few) vectors to final for 22R. The approach was visual, as there was only a broken layer at about 7000.
A highlight was NY Approach advising a Bonanza calling in to "get back on your last assigned frequency"... LOL! The pilot acknowledged that command pretty sheepishly. ;D
