Is one hour enough time to arrive before an international DL/KLM flight at JFK on Saturday night late (flying J)?
luggage?
Close you probably need at least 1:15! they close the desk usually an hour before flight.
No luggage
Then you should be good just print out your boarding pass before.
Make sure you are checked in and arrive at the counter at least 1 hour before. You are cutting it close.
If you don't have any baggage to check in and have your boarding pass already no need to show up an hour before, but yes it is recommended to come earlier. Maybe if you have pre you can feel safer when you arrive an hour before the flight.
No Precheck on INTL carriers
I got to the DL terminal 1hr before on domestic and missed my flight due to the long lines at security. You're really cutting it close.Edit: flew in J - even the priority security line was really long, and there's a long walk to the gates.
