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 Seattle to Baltimore 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 Seattle to Baltimore.
What is the typical flight duration from Seattle to Baltimore?
Flights from Seattle to Baltimore cover about 2,330 miles and typically take 5 hours and 5 minutes nonstop. The return leg from Baltimore to Seattle runs about 45 minutes longer, at 5 hours and 50 minutes.
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 Seattle to Baltimore?
Yes, Alaska Airlines and Southwest Airlines are the two carriers currently scheduled non-stop from Seattle to Baltimore, both flying daily. Alaska operates two flights a day, one around 9:03 AM and another around 9:36 PM, while Southwest runs a single daily flight departing around 9:25 PM. That adds up to roughly 21 non-stop flights each week on the route.
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 Baltimore?
BWI offers a full range of ground transportation into Baltimore and the wider region. The MTA Light Rail runs directly from the terminal to downtown Baltimore for $2.00 each way, with frequent service from early morning until after midnight on weekdays and Saturdays, making it the most-used and most economical option for the city center. Taxis, Uber and Lyft are readily available from designated pickup areas outside baggage claim and the upper level, providing the fastest door-to-door trips at a higher cost. Car rentals from major agencies are on-site, and a free shuttle connects the terminal to the BWI Rail Station for Amtrak and MARC trains serving Washington, D.C. and the Northeast Corridor. For most travelers heading into Baltimore itself, the Light Rail is the go-to choice, while rideshare and taxis offer the quickest direct transfer.

When is the cheapest time to fly from Seattle to Baltimore?
Fares from Seattle to Baltimore are lowest in late January, around $288. January is the cheapest month overall, averaging $296, followed by February ($297) and October ($331). June is the most expensive month at about $397, and fares peak in late June at about $413. The yearly average is $348. 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 Seattle to Baltimore?
Book about 5 weeks before departure for the best fares from Seattle to Baltimore, around $297. Booking in the final days before the flight costs about $372, $75 more. Booking six months ahead runs about $406. 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 Seattle to Baltimore?
Yes, overnight red-eye flights operate daily from Seattle to Baltimore on Southwest and Alaska Airlines. Southwest departs around 9:25 PM and lands at 5:20 AM the next morning, while Alaska departs around 9:36 PM and arrives at 5:41 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 Seattle to Baltimore?
Alaska Airlines and Southwest Airlines fly nonstop from Seattle to Baltimore. Alaska Airlines operates 14 weekly nonstop flights, with daily departures at 9:03 AM and 9:36 PM, while Southwest has one daily nonstop departing at 9:25 PM. Both carriers fly this route every day of the week.
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 Seattle to Baltimore?

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 Baltimore?
Baltimore has one commercial airport, Baltimore/Washington International Thurgood Marshall Airport, about 10 miles south of downtown and convenient to the Inner Harbor via light rail or taxi.
How do I get to Seattle-Tacoma Intl Airport from the city center?
From downtown Seattle, the Link light rail is the most popular and economical way to reach Seattle-Tacoma International Airport, taking about 38 minutes from Westlake Station in the heart of downtown. Ride-share services like Uber and Lyft, along with metered taxis, pick up on level 3 of the airport parking garage and offer a direct trip in roughly 20–30 minutes, though they cost significantly more than the train. A few shared shuttle services also run between downtown hotels and the airport, and driving yourself is possible but parking near the terminal is expensive. For most travelers, the light rail is the best balance of speed, cost, and reliability, while ride-share or taxi is fastest when traffic is light.

What aircraft are typically used on flights from Seattle to Baltimore?
Alaska Airlines and Southwest Airlines currently fly nonstop from Seattle to Baltimore, both using Boeing 737 family aircraft. Alaska operates the route with the most scheduled flights. The aircraft types are identical across the two carriers.
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.
