Ready Time
You know what you need to do. Ready Time helps you know when to start.
A maps app covers the drive to BOS. 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 20min
Be at BOS 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.
Logan is close to downtown as the crow flies, but every road route goes through a tunnel, and the tunnels are what blow up the estimate. Each terminal has its own curb on a one-way loop, so overshooting yours means going around again rather than pulling over.
Four terminals, each with its own checkpoint, and the walkways between them outside security are long. Terminals B, C and E connect after security, so a gate change among those three is a walk rather than a second screening. Terminal A does not connect that way, so arriving at the wrong building for a Terminal A flight means the shuttle or the walkway and another line.
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.
The Silver Line connects the terminals to South Station and the Blue Line stops a short shuttle ride away. Both skip the tunnels, which is the main advantage of taking transit at Logan. If you drive at rush hour, the tunnel is the buffer. Logan is also the rare airport with a real water option: ferries run to the Seaport and downtown when the weather cooperates.
For live waits, parking, and terminal maps, check the official BOS site.

Be at BOS 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 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 BOS is under Security at BOS 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 (20 minutes in the default plan). Replace the drive with your own route. The leave-by moment is the first travel row, "Drive to BOS" 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.
