Flight Deals from Washington to Houston from $111

The flight from Washington to Houston is about 1,220 miles. Nonstop service on Southwest typically takes 3 hours 20 minutes, while the return flight to Washington is 3 hours even, making the outbound leg about 20 minutes longer due to prevailing winds.

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.

Southwest Airlines flies nonstop from Washington (DCA) to Houston Hobby, with 21 weekly departures running daily. Flights leave throughout the day at roughly 6 AM, midday, and evening, with three to four departures each day.

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.

Fares from Washington to Houston are lowest in late January, around $176. January is the cheapest month overall, averaging $180, followed by October ($187) and September ($189). June is the most expensive month at about $212, and fares peak in late December at about $221. The yearly average is $198. 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.

For flights from Washington to Houston, the optimal booking window is roughly 6 to 9 weeks before departure, when average fares hover around $284. Booking about 50 days out tends to yield the very lowest prices at $282, while waiting until the last minute or booking more than 5 months ahead pushes fares up toward $460 or more.

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.

There are no nonstop red-eye flights from Washington to Houston, but connecting overnight itineraries do operate, with the overnight leg flown by Southwest. These connect through Chicago Midway (departing 9:30 PM, arriving 12:10 AM), Orlando (departing 10:40 PM, arriving 12:20 AM), or Nashville (departing 10:15 PM, arriving 12:25 AM), each landing in the early hours after midnight.

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.

Southwest Airlines flies nonstop from Washington to Houston, with 21 weekly flights departing daily from Ronald Reagan Washington National Airport to William P. Hobby Airport.

Southwest Airlines is the most reliable carrier on the Washington to Houston route, with 78.0% of flights arriving within 15 minutes of schedule and a cancellation rate of 1.1%. On-time arrival reliability for this route is solid, with Southwest operating daily service from Washington Reagan to Houston Hobby.

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).

Houston has two main airports. George Bush Intercontinental is the primary hub for United and most international and long-haul flights. William P. Hobby is closer to downtown and serves Southwest and other domestic low-cost carriers.

Getting to Washington Dulles International Airport from downtown Washington is easiest via the Metrorail Silver Line, which runs directly from the city center to the terminal in about 47 to 53 minutes and is the most popular and economical choice. Ride-share services like Uber and Lyft offer door-to-door convenience and are generally faster, while taxis operate 24 hours a day with a flat-ish fare around $65 and a travel time of 30 to 60 minutes depending on traffic. Metrobus Route 5A and the Silver Line Express bus provide cheaper public transit alternatives, and driving yourself is possible with on-site parking, though traffic on the Dulles Access Road can be unpredictable.

Southwest Airlines flies nonstop from Washington to Houston Hobby, using Boeing 737-700s on that route.

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.

Southwest Airlines is the airline currently scheduled nonstop between Washington and Houston, operating daily service from Reagan National to Hobby.
