I will be flying from Johannesburg on South African Airlines and arriving at JFK at 6:40am on a Saturday. I need to make my way from JFK to EVV via Delta or American (only two options from home airport - via Atlanta, Detroit, or Chicago). I do not wish to have a super long layover at JFK, as I want to get home. However, I do not want to book a ticket too close to the flight time and miss our connection. I am told I need at least 3 hours to clear customs, immigration, etc. The flight options out of JFK either get me home much later than I hoped or leave about 2 hours after I land, so I think the connection is too tight. And most of them have 2 connections between JFK and home...not something I want to do after a long flight.
I noticed there are a couple of nice flight options out of LGA to my home airport. If I were to book at ticket from LGA to home, how much time do you figure I need to allow to get to LGA from JFK? Is this something I can do reliably by taxi? Or would some sort of shuttle be more reliable and not dependant on traffic? There is a flight at 10am that only has 1 connection and puts me at home by 2:30pm, which would be ideal...but only allows me a little over 3 hours. Not sure if it is enough time to clear customs, immigration, and make my way over to LGA - go through security again, etc. Seems unlikely, but I wanted to ask those who fly into/out of LGA/JFK.
