Without this information, I’m a TSA Pre flyer who does not check a bag and who flys either American or United. I usually have a car rental that I’m returning, and so my plan is usually to arrive at the rental car return 2 hours out. Gives me time to drop off the car, take the AirTrain, go through security, and get to my gate. That’s always been sufficient.

I flew United international on an early Sunday morning in October with checked bags and had no issues, at all.

Airport is a nightmare in the afternoons and evenings, as is the traffic. Early flight, you have no issue.
