Ready Time
You know what you need to do. Ready Time helps you know when to start.
A maps app covers the drive to LGA. 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 30min
Be at LGA two hours before a domestic departure and three before an international one. That is a solid default here. Trim it only on routes and hours you already know well.
The rebuilt terminals are a genuine upgrade, but the roads feeding them are the same , and it's the Grand Central Parkway and the BQE that set your arrival time. Commercial flying happens in the rebuilt Terminals B and C; Terminal A, the Art Deco Marine Air Terminal, is closed to the public and now houses a private operator, so the choice on the ground is only B or C.
The new Terminal B and Terminal C checkpoints move well outside of the morning shuttle-flight rush, when the business crowd hits them all at once. A pedestrian path links Terminals B and C, but it sits outside security: switch terminals and you screen again, so the walk saves you the shuttle, but not the checkpoint.
The plan allows 20 minutes for a standard lane on a busy but normal morning. With TSA PreCheck, that drops to 10 minutes. A checked bag lengthens the one before it.
There's no direct rail link: it's a cab, a rideshare, or the Q70 bus from the subway at Roosevelt Avenue. Whatever the mode, cross-borough traffic is the input that matters, and it swings hard between 20 minutes and an hour. There is still no rail to LGA (the AirTrain plan was cancelled), so the bus and the road are the entire list.
For live waits, parking, and terminal maps, check the official LGA site.

Be at LGA two hours before a domestic departure and three before an international one. That is a solid default here. Trim it only on routes and hours you already know well. The plan above works back from there through security, bag drop, parking and the drive to a leave-by time.
The plan allows 20 minutes for a busy-but-normal standard lane. With TSA PreCheck it drops to 10 minutes, and you can edit either one to what you actually see. A checked bag lengthens the step before it. Checkpoint detail for LGA is under Security at LGA 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 (30 minutes in the default plan). Replace the drive with your own route. The leave-by moment is the first travel row, "Drive to LGA" 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.
