Methodology: learn how we calculate these charts

The charts “When is the cheapest time to fly?”, “How far in advance should I book?”, “What's the cheapest day of the week to fly?” and “What do round-trip flights from Phoenix to Washington cost?” are built from the prices Priceline customers actually paid for flights on this route over the past 12 months or more.

Where a route has too few bookings to fill every point in a chart, we borrow the shape of the curve from a group of routes with similar price behavior and fit it to the fares booked on this route.

Because past fares don’t reflect today’s market, we then adjust the historical prices for current conditions such as inflation and fuel costs, using the round-trip fares found in recent searches on this route.

The chart “When is the best time of day to fly?” is calculated directly from the fares found in recent searches, not from historical bookings.

Frequently Asked Questions

Everything you need to know about flying from Phoenix to Washington.

What is the typical flight duration from Phoenix to Washington?

Phoenix to Washington is about 1,975 miles. The typical nonstop flight takes about 4 hours 17 minutes heading east, while the return to Phoenix averages about 4 hours 52 minutes — the westbound leg is about 35 minutes longer.
Methodology
Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.

Are there any direct flights from Phoenix to Washington?

American Airlines flies nonstop from Phoenix to Washington National, with three daily departures (at 8:30 AM, 12:36 PM, and 11:52 PM) for 21 weekly flights. United also flies nonstop to Washington Dulles once daily at 8:50 AM, seven times a week. Both airlines are currently scheduled to run these nonstops daily.
Methodology
Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.

What are the ground transportation options in Washington?

Washington Dulles International Airport (IAD) offers several ground transport options to downtown DC, including the WMATA Metrorail Silver Line with a station connected to the main terminal, Metrobus Route 5A to L'Enfant Plaza, taxis, rideshare (Uber and Lyft), rental cars, and private car services like SuperShuttle. The Silver Line Metro is the most used and economical option, taking about 47–53 minutes and costing $2–6, but it involves transfers and limited late-night service. Taxis run 24/7, cost around $65, and take 30–60 minutes depending on traffic, while rideshare is also available around the clock and can be scheduled in advance. Private car service offers a direct, no-shared-stops ride with meet-and-greet options, particularly convenient for business travelers or those with heavy luggage.

When is the cheapest time to fly from Phoenix to Washington?

Fares from Phoenix to Washington are lowest in late January, around $344. January is the cheapest month overall, averaging $349, followed by February ($356) and August ($369). June is the most expensive month at about $415, and fares peak in late December at about $420. The yearly average is $389. Fares are adjusted to current market conditions.
Methodology
Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.

How far in advance should I book tickets from Phoenix to Washington?

Book about 5 weeks before departure for the best fares from Phoenix to Washington, around $373. Booking in the final days before the flight costs about $454, $81 more. Booking six months ahead runs about $514. Fares are adjusted to current market conditions.
Methodology
Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.

Are overnight (red‑eye) flights available from Phoenix to Washington?

Yes, overnight red-eye flights are available from Phoenix to Washington. American Airlines operates a daily red-eye from Phoenix to Reagan National (DCA), departing at 11:52 PM and arriving at 7:14 AM the next morning.
Methodology
Red-eye flights are identified from scheduled local departure and arrival times and block times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes. A flight counts as a red-eye when it departs in the afternoon or evening (3 p.m. or later local time) or in the early hours before 4 a.m., and is in the air at some point between midnight and 4 a.m. local time at both its departure airport and its arrival airport. An evening flight that lands before midnight at its destination is never counted, nor is a morning departure or a daytime long-haul that reaches the next calendar date only because of time zones. Each red-eye is labelled with its timing (for example, overnight and landing the next morning, or late-night and landing after midnight). For connecting itineraries the same rule is applied to the longer leg, from one representative day's flight search.

Which airlines usually operate this route from Phoenix to Washington?

American Airlines and United Airlines are the airlines currently scheduled non-stop from Phoenix to Washington, with American flying to Reagan National (DCA) and United to Dulles (IAD). American operates the route three times daily, while United runs one daily flight. American is a member of oneworld and United belongs to Star Alliance.
Methodology
Airlines and weekly frequencies come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.

How reliable are on‑time arrivals on this route from Phoenix to Washington?

American Airlines is the most reliable carrier on this route, with 83.1% of flights arriving within 15 minutes of schedule and a 1.1% cancellation rate. United follows at 82.1% on-time arrivals with a 0.4% cancellation rate, while Southwest trails at 79.3% on-time with no cancellations recorded.
Methodology
On-time arrival and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; a flight counts as on time when it arrives within 15 minutes of schedule. Carriers are ranked by arrival on-time rate on this route, and the carrier list itself comes from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).

Which airport should I use in Washington?

Ronald Reagan Washington National Airport is closest to downtown and popular attractions, ideal for business and domestic flights. Washington Dulles International Airport is farther out but serves as the primary hub for international and long‑haul routes. Baltimore/Washington International is a third option, mainly for low‑cost carriers and regional connections.

How do I get to Phoenix Sky Harbor International Airport from the city center?

Getting to Phoenix Sky Harbor International Airport from downtown Phoenix is quickest and most popular by ride-share or taxi, which take about 10–15 minutes and are available 24/7 at both terminals. The most budget-friendly option is the Valley Metro Rail: take the light rail to the 44th Street/Washington station, then transfer to the free PHX Sky Train, which runs 24/7 directly into the terminals. Valley Metro Bus routes 13 and 44 also connect to the Sky Train station, and many downtown hotels offer courtesy shuttle service. Driving yourself is easy with short-term and long-term parking at the terminals, plus economy lots connected by the Sky Train, though parking fees will be higher than transit.

Are there hotels or sleeping facilities at Washington airport?

Washington Dulles International Airport (IAD) has a hotel right inside the airport: the Washington Dulles Airport Marriott, which is located inside the airport campus perimeter at 45020 Aviation Drive and offers a complimentary shuttle directly to the terminal. For uninterrupted sleep, several nearby hotels are connected by free airport shuttles, including the DoubleTree by Hilton Washington Dulles Airport, which is a 15-minute walk from the terminal and runs a complimentary 24-hour shuttle, and the Hyatt Regency Dulles International. Day rooms are available at the airport, though there are no sleep cabins or pods.

What facilities and services are available to travelers at Washington Dulles International Airport?

Washington Dulles International Airport offers free Wi-Fi and charging stations throughout for travelers. An Interfaith Chapel, located in Concourse A across from Gate A32, is always open for quiet reflection. Travelers with pets can use one of four designated pet relief areas, both inside the concourses and outside the terminal. Dining options are available in the main terminal and all four concourses, with some restaurants supporting mobile ordering ahead of arrival. The airport also has retail shops offering travel essentials and souvenirs, and a USO Lounge for military personnel and their families opposite Baggage Claim 12.

At Phoenix Sky Harbor International Airport, travelers can arrange wheelchair assistance through their airline or by using the blue phones on the PHX Sky Train platforms, and the airport offers a Compassion Cacti lanyard program, a Sensory Room, free Aira visual interpreting, ReBokeh app-based assistive technology, and accessible restrooms throughout. Washington Dulles International Airport provides wheelchair assistance arranged through your airline, airport shuttle buses and rental car shuttles equipped with wheelchair lifts or ramps, accessible parking in designated spaces, and a Hidden Disabilities Sunflower lanyard program with lanyards available from the USO Lounge or Information Desks daily between 8:00 AM and 8:00 PM. Neither airport publishes a required advance-notice period for wheelchair assistance, so travelers should arrange mobility support through their airline before the flight.

What aircraft are typically used on flights from Phoenix to Washington?

American Airlines, which operates the most nonstop service from Phoenix to Washington (into Reagan National), flies Boeing 737 MAX 8s and other Boeing 737 family aircraft on this route. United Airlines also flies nonstop from Phoenix to Washington Dulles, using Boeing 737 MAX 9s.
Methodology
Aircraft types come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.

Which airline alliances serve flights from Phoenix to Washington?

American Airlines and United Airlines are the carriers currently scheduled non-stop from Phoenix to Washington, with American serving Reagan National and United serving Dulles. American's oneworld and United's Star Alliance are therefore the alliances operating this route non-stop; other alliances may reach Washington from Phoenix only via connections.
