I know this question has been answered before, but that was 5 years ago and most airports have changed a lot since then. On 3/6/2019 I will be travelling from Boston to Punta Cana on Delta with a layover at JFK. I only have a layover of 90 minutes and need to get from Terminal 2 to Terminal 4. What is the best way to accomplish that, and do I still not need to go through TSA screening again? I would really appreciate any suggestions.

  • While the link to Delta's website in the previous question now redirects to an airport map, the "jitney" is still shown on that map as running airside between Terminals 2 and 4. So I think it's safe to say that it still runs. – Michael Seifert Jan 23 '19 at 15:13
