PWM vs Boston Logan: when Portland Jetport quietly beats BOS on total trip cost

Portland International Jetport in Maine and Boston Logan International Airport will never look equal on a route map, but your credit card statement does not care about route maps. It cares that the Portland Jetport Pink Lot runs $10 a day, while Logan’s cheapest catalogued daily rate starts at $23 in Economy Parking. It also cares that our database lists 12 parking lots at PWM and 12 at BOS, and that the lowest of Portland’s twelve is less than half the price of Boston’s.

On a simple 3‑day trip, that gap is not theoretical. PWM Pink Lot at $10 per day is $30. BOS Economy at $23 per day is $69, and the higher “Economy Parking Garage” entry at $37 per day is $111. That is before fuel, tolls, or whatever the East Boston approach eats out of your Friday afternoon.

In the year I was still filing weekly pieces for Travel + Leisure and bouncing between Boston’s South End and friends in Maine, I finally admitted something that is more context than data: the ground‑cost gap had stopped being a rounding error and started dictating which airport I used. Logan wins on breadth. PWM wins on simplicity. The real question is when that simplicity becomes the rational choice.

Should Portland flyers drive to Boston Logan to save on airfare, or stick with PWM? (PWM vs BOS airfare and parking, Portland Jetport vs Logan total trip cost)

If you live in southern Maine or coastal New Hampshire, the real question is very specific: PWM vs BOS airfare and parking, and does driving to Logan actually save money once you add ground costs?

Once you combine PWM’s $10–15/day parking with the $2 city bus, Boston typically needs a clear airfare advantage to win. PWM is not just the airport for people who dislike big terminals. It is often the fiscally sensible home base.

To keep this from turning into a parking brochure, I will compress the solo PWM details and focus on the PWM vs BOS spread.

PWM vs BOS at a glance: parking and basic ground costs

Here is the core comparison for a straightforward 3‑day weekend, one car, no exotic hacks.

Parking price floor

PWM long‑term options

From our PWM data, the long‑term picture is almost aggressively simple:

• Pink Lot Offsite Parking: $10/day
• Pink Lot: $10/day
• Long-Term Parking – Green Lot: $15/day
• Long-Term Parking – Blue Lot Surface: $15/day
• Parking Garage – Blue, Purple, Red, Orange, Yellow Levels: $15/day
• Level 3 Red Lot: $15/day
• Level 4 Orange Lot: $15/day
• Level 5 Yellow Lot: $15/day

There is also Hourly/Short-Term Parking – Blue Lot Garage at $48/day, $2/hr, but for trips the story is one line: you pay $10/day in Pink, or $15/day almost everywhere else.

BOS parking spine

Logan’s data is busier, but the meaningful spine runs like this:

• Economy Parking: $23.00/day
• “Economy Parking Garage” entries: $37/day, $5/hr
• Central Parking: $42/day, 3‑minute walk
• Central Parking Garage: $46/day, $10/hr, 5‑minute walk
• Terminal B Garage: $47/day, 2‑minute walk
• Valet Parking: $60.00/day, 1‑minute walk

Side‑by‑side weekend parking totals (3 days, one car)

• PWM Pink Lot: 3 x $10 = $30

• PWM $15 long‑term lots: 3 x $15 = $45

• BOS Economy at $23: 3 x $23 = $69

• BOS higher Economy Garage at $37: 3 x $37 = $111

• BOS Central at $42: 3 x $42 = $126

• BOS Valet at $60: 3 x $60 = $180

Even before fuel or tolls, Boston’s entry‑level parking is more than double PWM’s Pink Lot for a long weekend, and it climbs very quickly.

Airport size and friction: compact PWM vs Logan’s multi‑terminal layout

Money is only half the story. The other half is how much physical airport you have to digest.

PWM is tiny in the best way. Our data shows 2 terminals and 11 gates total, all functionally wrapped into the Main Terminal. The Parking Garage – Blue, Purple, Red, Orange, Yellow Levels and the $15 lots form an easy ring around that single building. This is one of the few airports where “a short walk to the terminal” reads as plain description, not aspirational copy.

Logan is a full New England ecosystem. The database frames 4 terminals, including Terminal E with its 11 gates, alongside a dedicated Central Parking Garage, a Terminal B Garage, and an intricate set of approach roads. You are not just choosing a price point, you are choosing a parking product that maps cleanly to your terminal and tolerance for shuttle buses.

For someone in Portland, Biddeford, or York, PWM’s choice set is almost charmingly blunt: pay $10/day in Pink and shuttle a short distance, or pay $15/day and walk in. At BOS the spreadsheet doubles as a flowchart, and every simplification tends to cost you another ten or twenty dollars per day.

Ground transport: PWM’s $2 city bus vs Logan’s per‑person shuttles

Ground transport is where Portland’s “small” infrastructure starts to look sophisticated.

PWM into town

The airport lists Bus, Taxi, Shuttle, Rideshare as its modes, but the hero is the METRO Bus Route 5 to Downtown Portland:

• $2
• 15–25 minutes to downtown

If you prefer a car, the Taxi from Baggage Claim Taxi Stand runs $15–25 and 10–15 minutes, and app‑based rideshare pickup (Uber/Lyft) sits in the $12–25 band for roughly the same timing. Add Hotel and Off-Airport Parking Shuttles at $0–10 (often complimentary), plus Regional Courtesy Shuttle / Ground Transportation Vans at $20–60 if you are heading farther afield.

The key pattern is that most PWM ground costs are per car or flat‑fare bus, not per person.

BOS into the city and suburbs

Logan, predictably, gives you everything: shuttle, bus rapid transit, intercity coach, boat, rideshare, subway. In our data, the cheapest airport‑to‑city options framed explicitly are the Uber Shuttle and Lyft Shuttle, both at under $20 per person with pricing that varies by route.

You also have the MBTA Silver Line SL1 bus rapid transit and MBTA Blue Line subway, along with the string of Logan Express Braintree, Logan Express Framingham, Logan Express Woburn, Logan Express Back Bay, and Logan Express Peabody coaches, plus the Massport Water Taxi.

It is versatile, and for greater Boston it is essential. For someone who actually lives in Portland or coastal New Hampshire, though, those per‑person shuttle prices mount quickly compared with a $2 bus or a single $15–25 taxi ride on the PWM side.

Break‑even cheat sheet: how much cheaper must BOS airfare be?

This is the piece most people hand‑wave. Here is a compact way to think about it using only the numbers in the dataset and a couple of clearly labeled assumptions.

Baseline: solo traveler, 3‑day weekend

PWM ground costs (solo)

• Parking in Pink Lot: 3 x $10 = $30
• METRO Bus Route 5: $2 each way, so $4 roundtrip
• PWM solo ground total: $34

If you use a $15 long‑term lot instead of Pink, that rises to $49.

BOS ground costs (solo)

• Parking in Economy Parking: 3 x $23 = $69
• One airport shuttle such as Uber Shuttle: assume it runs up to $20 per person each way. If you assume $20 per person each way, that is about $40 roundtrip in shuttles.
• Illustrative BOS solo ground total: ~$109

If you are stuck with a $37 “Economy Parking Garage” instead, your parking alone becomes $111, before any shuttle or MBTA Silver Line SL1 costs.

From that:

• Solo weekend traveler: Logan typically needs to be about $75 cheaper in total airfare (roundtrip) than PWM before its higher ground costs are offset.

Families and longer trips: two simple thresholds

Now scale that logic without inventing new price points.

• Family of 4, 7‑day trip, one car: PWM’s parking is $70–105 for the week (Pink vs $15 lots), plus car‑based transfers. BOS Economy is $161 for the week, and using a shuttle priced “under $20 per person” each way, a roundtrip for 4 people can easily sit in a band that makes total BOS ground somewhere around $200–320.

  • Family weeklong threshold: Boston generally needs to be at least $80–200+ cheaper overall on airfare across the family before it really wins on total trip cost.

• Solo, weeklong parking decision: Stretch the solo weekend pattern out. Parking differentials between PWM and BOS scale linearly, while bus and shuttle costs do not change much. If PWM is already saving roughly $75 on a 3‑day trip against BOS Economy plus shuttle, a longer stay simply increases that gap, so Logan’s fare advantage has to grow, not shrink.

  • Solo weeklong threshold: expect BOS to need an even larger $75+ total fare advantage over PWM before it makes sense, especially if you drift above Economy into Central or Terminal B garage pricing.

This is the part I was wrong about for years. Logan’s parking looks tolerable in isolation, but once you bolt it to per‑person shuttles and longer stays, the gap you need on airfare is not pocket change.

Two quick lived scenarios

A couple of very common patterns in southern Maine and coastal New Hampshire make this more concrete.

Scenario 1: Family of 4, 7‑day trip

Assume one car, seven days, everyone flying together.

PWM

• Pink Lot: 7 x $10 = $70
• Even using taxis at the top of the $15–25 range each way, you might add $50 in city transfers for the entire family.
• Ballpark PWM ground: $70–120 total for four people

BOS

• Economy Parking: 7 x $23 = $161
• If you again assume shuttles are roughly $20 per person each way, four people can approach $160 in roundtrip shuttle charges.
• Illustrative BOS ground: often $200–320 for the same family

As above, that means BOS airfare has to outperform PWM by roughly $80–200+ across the four tickets before the “drive to Logan” instinct holds up in financial terms.

Scenario 2: No‑car PWM plus coach access to BOS

Now imagine you live in Portland, do not want to park at Logan at all, and are thinking about coaching to Boston.

The database here centers on airport‑side modes, so the picture is schematic rather than numeric, but the trade‑offs are clear:

• PWM to downtown Portland on the METRO Bus Route 5: $2, then an intercity coach south, then Logan via the MBTA Blue Line, MBTA Silver Line SL1, or a shuttle.
• BOS side: you have avoided parking, but you have layered in multiple legs and, if you use airport shuttles, per‑person costs again.

For a very long international trip, that choreography can absolutely make sense. For a standard week or less, PWM’s $10–15/day parking and $2 bus start to look almost conservative by comparison.

---

Logan is still the New England heavyweight, and to be fair there are trips where its nonstop network is non‑negotiable. If you need a route out of Terminal E that PWM will never see on its departure board, no amount of $10 parking should sway you.

For everything else, especially if your life is in Portland, Saco, or along the Seacoast, PWM’s $10 Pink Lot, tight cluster of $15 long‑term options, and $2 bus into town make it more than a charming regional. It is often the rational answer to the question you should actually be asking: At what fare difference does PWM vs BOS stop being a habit and start being a real savings decision?
