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 Portland 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 Portland to Boston.

What is the typical flight duration from Portland to Boston?

The flight from Portland to Boston is about 2,530 miles. Nonstop flights typically take about 5 hours and 23 minutes eastbound, while the return leg to Portland averages about 6 hours and 13 minutes, making the westbound direction roughly 50 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 Portland to Boston?

Yes — Alaska Airlines and JetBlue Airways are the two carriers currently scheduled non-stop between Portland and Boston, both flying daily. Alaska runs 14 non-stop flights a week with departures at 07:00 and 21:56, while JetBlue operates 12 weekly with departures at 14:16 and 23:27. That adds up to 26 non-stop flights each week, with service every day of the week.
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 solid ground transportation options to the city center. The Silver Line SL1 bus is free from the airport to South Station in downtown Boston and is the most-used and most affordable option, while the Blue Line subway reaches downtown in about 15 minutes after a free shuttle from the terminals. Taxis to downtown cost about $25, ride-hailing services like Uber and Lyft start around $20, and car rentals are available outside the main terminal building via Massport shuttle buses. Water taxis and the MBTA ferry provide scenic alternatives to Long Wharf and other harbor points, with ferry fares at $2.40 and water taxis around $15. The Silver Line SL1 is the fastest and most popular way to get from the airport to downtown Boston.

When is the cheapest time to fly from Portland to Boston?

Fares from Portland to Boston are lowest in late January, around $406. January is the cheapest month overall, averaging $421, followed by February ($427) and September ($472). December is the most expensive month at about $564, and fares peak in late December at about $603. The yearly average is $495. 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 Portland to Boston?

Book about 5 weeks before departure for the best fares from Portland to Boston, around $403. Booking in the final days before the flight costs about $503, $100 more. Booking six months ahead runs about $551. 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 Portland to Boston?

Yes, red-eye flights are available from Portland to Boston. Alaska Airlines operates a daily nonstop red-eye departing around 9:56 PM and landing at 6:20 AM the next morning, while JetBlue runs one on Monday, Thursday, Friday, Saturday, and Sunday departing around 11:27 PM and arriving at 7:48 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 Portland to Boston?

Alaska Airlines and JetBlue Airways are the airlines currently scheduled non-stop from Portland to Boston, each flying daily. Alaska operates 14 weekly flights with departures at 7:00 AM and 9:56 PM, while JetBlue offers 12 weekly flights departing at 2:16 PM and 11:27 PM. Alaska Airlines is a member of the oneworld alliance, and JetBlue is not a member of any 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 Portland to Boston?

Alaska Airlines is the most reliable carrier on the Portland to Boston route, with 80.6% of flights arriving within 15 minutes of schedule and a cancellation rate of just 0.3%. JetBlue trails at 60.0% on-time arrivals with a 0.8% 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).

Which airport should I use in Boston?

Boston Logan International Airport is the only commercial airport serving Boston. It is about 3 miles from downtown and offers direct access to popular attractions via public transit, taxis and ride shares.

How do I get to Portland Intl Airport from the city center?

Getting from downtown Portland to Portland International Airport is straightforward with several options. The MAX Light Rail Red Line is the most popular and affordable choice, running directly from the city center to the airport in about 45 minutes.

What aircraft are typically used on flights from Portland to Boston?

Alaska Airlines operates the most nonstop flights on this route, using Boeing 737 family aircraft. JetBlue also flies nonstop with Airbus A320 family and Airbus A220 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.

Which airline alliances serve flights from Portland to Boston?

Alaska Airlines and JetBlue fly nonstop between Portland and Boston, each with daily service. Alaska Airlines is a oneworld member, while JetBlue belongs to no alliance. Other alliances may reach the route through connections, but these two carriers are the ones currently scheduled nonstop.
