JFK Airport Shuttles

As soon as you disembark the plane go straight to gate 11A at Terminal 3 - there is a Delta bus that shuttles between T3 and T4 every 15 minutes. Once the bus drops you off at T4 there is no need to clear security again there(the drop off point is right at the B gates).

I would suggest you taxi even it is not the most cost effective way. Public transportation at that time of the night is not advisable.
Taxi will be on the meter and it will cost you ~$80-$90 for the whole cab.

Yes, most of them will take you to any point in Manhattan for $18.50(if you are going to hotels) or $18.50 - $25(if you are going to resident address).The rate is per passenger.

Take subway E towards Jamaica,Queens. Get off at Sutphin Blvd stop and take Airtrain to JFK terminals.At that time is safe to ride the subway.

Most likely you will clear immigration and customs by 0700(if not earlier). There is a bus in front of the terminal - NYAS(New York Airport Service) express bus that goes to LaGuardia every 30 min. The cost is $13. Check with the NYAS representative(who is always in the front) what time is the next bus to LaGuardia. The travel time between JFK and LGA is 15-20 min.
As long as you are at LGA on or before 0845 you should be OK.

If you are going near Times Square, NYAS(New York Airport Service) express bus is your best bet.
It leaves in front of every terminal every 20 minutes and costs $15/passenger. The tickets can be purchased either from their representative(who is in the front of the terminal all the time) or on the bus.
