I am thinking to fly into JFK on Jet Blue then catchg a Delta flight to Greece. Not checking luggage, do I have to go back thorugh security if I have pre checked in for my Delta flight?
If I fly Delta to JFK I have a 1.25 hr lag between flights. The Jet Blue flight would give me 2.5 hr's so I prefer to have more time. But, if I am having to go to different terminals and /or go through security the extra time may not help. Whats't the best way?
