For a 6 am flight If I get to JFK between 4:30/5:00 am is that enough time to get through security? I will not be checking any bags and only have a carry on. This is for an international flight and will be post labor day in early September.

If it's not I will make other arrangements and get there earlier.

I'm also thinking of signing up for clear but have not done that yet. I can' find any information if JFK terminal 5 has clear or not. Can anyone confirm?
