This question already has an answer here:
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.
