Be at IAD two hours before a domestic departure and three before an international one. That still doesn’t tell you what time to leave the house, so put in your departure time and adjust the drive, parking and bags.
Every row is editable. Tap the departure or any duration and the plan recomputes backward. The first travel row is your leave-by time.
Until you know your gate, budget for the longer walk. At IAD, you take a ride between security and the gate either way. Pick the one that matches your concourse.
The 40-minute drive is a typical run from Washington without traffic. In the app, set Washington Dulles International as the destination and Apple Maps fills in the time from where you’re leaving.
Still check traffic for the hour you’ll go (real drive to IAD). Change the row and every step before it moves.
A maps app covers the drive to IAD. 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 50min
Two hours domestic, three international
Ahead of your departure time
That is a solid default here. Trim it only on routes and hours you already know well.
Dulles is a long way from the city, and the gates are a train ride past security, so both ends of the trip are longer than they look. Everything starts at the one main terminal, so there is no building to get wrong here, just a long stretch of concourse once you're through security.
After the main-terminal checkpoint, most gates are out in midfield concourses reached by the AeroTrain; it runs frequently, but it's a leg with a wait, and international departures stack the evening peak. The AeroTrain reaches Concourses A, B, and C, but Concourse D is still served by the old mobile lounges, so a D gate is a different and slower kind of leg.
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.
The Silver Line now runs all the way to a station connected to the terminal by walkway, which finally gives Dulles a predictable transit path. Driving, the Dulles Access Road itself is quick, but the roads leading to it can be slow. The garages sit against the terminal while the cheaper lots need a shuttle, so the lot you pick changes the front of the plan rather than the end of it.
For live waits, parking, and terminal maps, check the official IAD site.

Save this IAD plan in Ready Time and it tells you when to start packing and when to leave for the airport.
Ready Time
You know what you need to do. Ready Time helps you know when to start.
Be at IAD 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 IAD is in the section 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, the ride out to your concourse, security, bag drop, parking, then the drive (40 minutes in the default plan). Replace the drive with your own route. The leave-by moment is the first travel row, "Drive to IAD" by default.
Taking the train instead? The Amtrak station pages use the same kind of plan without security. The leave time calculator works for any appointment, and the wake-up time calculator runs it back to the alarm.
Two hours early still leaves the morning open: when to pack, when to leave. The plan keeps subtracting past the drive until it lands on a start time. Ready Time saves that chain and alerts you at each step, and can pick the flight up from your calendar.
Get a nudge at the right moment, while there's still time to act.
Each step gets its own alert, so you know what's next and how long you have.
