Traveling by plane is fun — jet-setting over beautiful blue waters or rolling hills, taking in cloud formations, and landing in London, England, in a matter of hours is unlike anything else.
The whole navigating the airport part? Not always as fun.
To help make your time at the Dulles International Airport (IAD) as smooth as possible, we’ve created a guide that covers everything from gates and parking to details on the airport’s 159 nonstop flights.
Here’s your guide to IAD, the fourth-largest airport in the US by land area.
Current updates
With the holiday season right around the corner amid the current government shutdown, it’s even more important to be prepared.
Operation during the shutdown
Although the airport remains open, many employees are currently working without pay. While cancellations have stayed relatively low, as of early November, there have been reports of flight delays and longer security lines. Travelers are advised to arrive early and check their flight status regularly.
What to know
- Parking | Not everyone has a bestie who will drop them off at the terminal at 3 a.m. Thankfully, Dulles has options. See rates for short-term, long-term, and valet parking.
- TSA | According to the IAD’s website, it’s recommended to get to the airport two hours before departure. For international flights, three hours in advance.
- Map it out | If you’re like us and need to completely visualize a place before you step foot inside, these maps of the entire airport will be your saving grace.
- Food and drink | Fuel up for your flight at one of the Dulles Airport’s restaurants or shops. Example: Grab a bite (or drink) at the Devil’s Backbone Taproom. Or maybe you’re looking for something a bit more familiar, like Cava or Chick-fil-A.
- Reminder | As of May 7, 2025, flyers now need a REAL ID to board commercial flights in the US.
- Flight status | While we recommend staying updated via your respective airline, you can also check the airport’s dashboard for your flight status in a pinch.
