JFK Airport T4. For departing flights it's really a nice terminal with quite a bit of choice on stores and 2 or 3 places to eat. Getting through check-in isn't a big problem and rarely takes long. On the times I've had to go through it took about 15 min on average. Arriving at T4 is a different story though. I forgot the exact number customs counters they have think it's about 22 they rarely are all open. Most times there were only 4 or 5 open at a time. Bare in mind that it takes roughly between 5 and 10 minutes at the counter itself to go through and that there's usually 3 or 4 flights coming in at the sametime it builds up a line of roughly 600 to 800 passenger. sometimes more sometimes a bit less. So you do the math of how long you'll have to wait in line. For me it was an avarage of 2 hour waiting whereas 30 minutes of them there was no movement at all. My advice to everyone traveling to JFK and arriving at Terminal 4 get a front row seat in the plane or as closest to the front as possible and when you're allowed to get off the plane hurry to the line as the difference between a front row seat and a rear row seat can easily add a few hours to your waiting time. Other than that JFK is a nice airport and the clerks are usually friendly at T4. Even though a lot of them seem to be really bored at doing their jobs.
