I know every time we have had an event at the Millennium Hotel Hudson Theater in New York, the lobby is loaded with FA's Pilots and what not all checking out, and then a couple hours later some more checking in.
That's quite a way from the airport, so they at least get to stay in the Times Square area instead of JFK.
One of the events is always in Feb, and it was funny one night, they were waiting and waiting for the bus, delayed because of a snowstorm that night. A few hours later they were all back, never made it the flight was canceled.
Foreign crew, little english, don't know who though (all blue head to toe if that helps)
