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 Boston 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 Boston.
What is the typical flight duration from Seattle to Boston?
The flight from Seattle to Boston is about 2,490 miles. Nonstop flights typically take 5 hours 25 minutes eastbound, while the return trip from Boston to Seattle takes about 6 hours 20 minutes, making the westbound leg notably 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.
Are there any direct flights from Seattle to Boston?
There are direct nonstop flights from Seattle to Boston, with Alaska Airlines, Delta Air Lines, and JetBlue Airways all flying the route daily. Alaska operates 32 flights a week, Delta 27, and JetBlue 14, with departures spread across the day from early morning through late evening. All three carriers run service every day of the week, so there is no day without a nonstop option.
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 Boston?
Boston Logan offers several reliable ways into the city center: the free Silver Line SL1 bus runs directly to South Station in about 21 minutes and connects to the Red Line, while the Blue Line subway reaches downtown in about 15 minutes via a short free shuttle from the terminals. Taxis cost about $25 to downtown, ride-hailing apps like Uber and Lyft start around $20, and water taxis to the waterfront run about $15. Car rentals are available off-terminal via Massport shuttle buses. The Silver Line SL1 is the most-used option for its free, no-transfer service to South Station, though the Blue Line is the fastest transit route into the core.

When is the cheapest time to fly from Seattle to Boston?
Fares from Seattle to Boston are lowest in late January, around $345. February is the cheapest month overall, averaging $354, followed by January ($362) and March ($387). July is the most expensive month at about $527, and fares peak in late December at about $534. The yearly average is $439. 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 Boston?
Book about 4 weeks before departure for the best fares from Seattle to Boston, around $351. Booking in the final days before the flight costs about $410, $59 more. Booking six months ahead runs about $466. 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 Boston?
Yes, overnight red-eye flights operate nonstop from Seattle to Boston every night. Delta and JetBlue fly daily red-eyes departing around 11:15 PM and 11:46 PM, and Alaska runs one six nights a week (all but Saturday) leaving around 11:18 PM. All of these land the next morning between roughly 7:35 AM and 8:04 AM.
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 Boston?
Alaska Airlines, Delta Air Lines, and JetBlue Airways operate nonstop flights between Seattle and Boston. Alaska offers the most frequency with 32 weekly flights, followed by Delta with 27 and JetBlue with 14; all three carriers fly daily. Alaska is a oneworld member, Delta is SkyTeam, and JetBlue is not part of an 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 Seattle to Boston?
Delta Air Lines is the most reliable carrier on this route, with 81.3% of flights arriving within 15 minutes of schedule and a cancellation rate of 0.9%. Alaska Airlines arrives on time 66.2% of the time with a 0.3% cancellation rate, while JetBlue lands on time 63.4% of the time with a 0.9% cancellation rate.
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).

Alaska Airlines, which flies the most nonstop Seattle–Boston flights, uses Boeing 737 family aircraft on the route. Delta operates Airbus A321neo, and JetBlue flies a mix of Airbus A321 and Airbus A320 family aircraft.
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.
