For the record, the only issue I have had is getting off an international flight and having to wait to check in, but that's minor. I never waited more than a few minutes to be served. Sure it's busy, but it's JFK, what do you expect...that you are the only traveler who has been delayed? The new Delta rules will trim the population next year. As a Boston based FF, I go thru' JFK a bit and I am fine with it.
