Be at JFK two hours before a domestic departure and three before an international one.
A maps app covers the drive to JFK. Bag drop, security, and the walk to your gate usually take longer, and they are the steps people misjudge.
Here is the same plan drawn to scale. The first block is travel; the next two are the airport. A checked bag grows one, a far gate grows the other.
Front door to boarding: 2hr 55min
Be at JFK two hours before a domestic departure and three before an international one. At an airport this size, treat those as a floor. They assume a normal day, not a holiday crush or a long security line.
The Van Wyck Expressway is the hard part at JFK: the last few miles can take as long as the rest of the trip. Five terminals are open and most do not connect after security, so a terminal mix-up means the AirTrain and a second screening.
Each terminal runs its own checkpoints and they don't share lines, so the wait depends on which terminal your airline uses, and ongoing terminal construction periodically moves airlines around, so double-check yours. The AirTrain is free between terminals, so fixing that mistake doesn't cost you money, just time.
The plan allows 25 minutes for a standard lane on a busy but normal morning. With TSA PreCheck, that drops to 15 minutes. A checked bag lengthens the one before it.
AirTrain connects every terminal to two subway stations and to the LIRR. Howard Beach is the one people know, on the A, but the E, J and Z reach Sutphin Blvd-Archer Av at Jamaica and that is the quicker way in: about 35 scheduled minutes from Midtown against roughly 47 on the A. The LIRR from Penn to Jamaica is the most predictable of the three. Drivers still hit the terminal loop, which crawls at peak. Terminal 1 is rebuilding in phases; confirm your terminal close to travel day.

Be at JFK two hours before a domestic departure and three before an international one. At an airport this size, treat those as a floor. They assume a normal day, not a holiday crush or a long security line. The plan above works back from there through security, bag drop, parking and the drive to a leave-by time.
The plan allows 25 minutes for a busy-but-normal standard lane. With TSA PreCheck it drops to 15 minutes, and you can edit either one to what you actually see. A checked bag lengthens the step before it. Checkpoint detail for JFK is under Security at JFK above.
Earlier than for a domestic one. International boarding starts 45 minutes before departure instead of 30, which pulls every step earlier. Use the airline desk for bags: documents get checked and counters often close an hour out. That also covers lap infants, unaccompanied minors, and oversized bags. If your boarding pass names a boarding time, match that.
Work backward from departure: boarding, time at the gate, the walk, security, bag drop, parking, then the drive (45 minutes in the default plan). Replace the drive with your own route. The leave-by moment is the first travel row, "Drive to JFK" by default.
Taking the train instead? The Amtrak station pages use the same kind of plan without security. Flying from somewhere not listed? The airport leave time calculator has the same rows with your own numbers, and the wake-up time calculator runs it back to the alarm.
Start the plan in the app, and the Lock Screen and Dynamic Island show the time left, with a bar that fills as each step passes.
Glance at it in the terminal without opening the app.
Every step also gets its own alert, and sharing the plan gives whoever is driving the same leave time, with alerts on their phone.
