How we verify what is on this site

Where a number has to come from

1. Massport’s own page, for anything about Logan’s garages, shuttles, terminals or Logan Express.
2. The operator’s own site, for anything about a private lot.
3. The MBTA or another first-party transport source, for transit.
4. Our own affiliate configuration, for who pays us.

What is explicitly not a source: our own older pages. Published copy is a lead to check, never evidence. Several claims removed from this site in September 2026 had survived for months purely because they were already published.

What “verified” means here

A verification badge means a person or process opened that source on that date and read that figure. It is attached to the individual fact, not to the page. If we update unrelated wording on a page, the rate keeps its own older date, because nobody re-read the rate.

Where a source contradicts itself we say so rather than pick the convenient number. Massport, for example, titles one facility the Economy Parking Garage and then calls it the Economy Lot in its own body text; we follow the official name and record the discrepancy.

Fixed rates versus live quotes

Massport publishes a rate table, so we can print those numbers and calculate a real total for your dates from the published tiers. Off-airport operators price inside their own booking flow, so there is no number to print. We show those as a live quote and send you to the operator. We will not estimate them, because an invented total is worse than no total.

What we cannot know

• Live space availability. Massport runs a parking status page and describes it as real time. We do not mirror, cache or reproduce it, and nothing on this site is a live space count. Check Massport directly before you drive.
• What an operator will quote you. Dynamic pricing moves with date and demand.
• Future construction dates. Massport does not publish a completion date for the Terminal E garage, so we do not print one, even though other sites do.

How often this is checked

A scheduled job runs on the first of each month and re-reads the sources behind our rate dataset, flagging anything that has drifted or that it could not reach. It is designed to fail loudly: a check that quietly passes when a source is unreachable would be worse than no check. When it fails, a person opens the page and re-reads it by hand.

That is the entire cadence. We do not claim a daily sweep, and we do not have one.

Corrections

When we have published something wrong we correct it on the page and say so, rather than deleting it quietly. The most recent entries from our own verification log:

• 2026-10-09: unsourced statements in page bodies were checked against their sources and cut or relabelled. Removed from the holiday page: "hundreds of missed flights every year", a count of days Logan's garages were full in 2024, and a claim that Logan has no overflow parking (Massport's own pages say attendants direct travelers when overflow parking is in effect); it also said parking at Logan Express suburban lots is free, and Massport lists it at $7 a day. Removed from Terminal A: Delta departure times and destinations, a stated morning queue time, a satellite-concourse walking time, and Delta One lounges (Delta places two Sky Clubs on Concourse A). Removed from Terminal B: lounge locations and a claim that its garage is inside the building. Removed from Terminal E: the destinations column and where the Route 88 shuttle stops. Central Parking's walking times are now labelled as our estimates. Removed from the off-airport page: claims that off-airport lots cost less, have covered bays, add an 8 to 15 minute shuttle, or that loyalty programs belong to national chains; no operator publishes a rate or a transit time.
• 2026-10-01: every FAQ answer on the site, the park-and-fly hotel table and llms.txt, the file AI assistants read, checked against Massport, the hotels and the operators. Wrong and corrected: airline-to-terminal lists on six pages (Massport lists no Spirit Airlines or Silver Airways at Logan, Alaska Airlines only at Terminal B, WestJet only at Terminal E, Aer Lingus only at Terminal C, and Aer Lingus and Etihad arrive at C, not E); Terminal B described as East and West sides with airline gate ranges, where Massport publishes two checkpoints, Checkpoint 3 for Gates B1-22 and Checkpoint 4 for Gates B23-40; 'the former Terminal E surface lots are currently closed', which no Massport page says (Massport lists three garages and is building a 4,000-space garage at Terminal E, no opening date); off-airport valet described as a driver meeting you at the terminal curb, where both operators that offer valet do it at their own lot and you ride the shuttle; 'only PreFlight publishes a shuttle frequency', overtaken when Park N Boston began publishing every 30 minutes; and two source notes saying Massport's Gold Parking Express terms name Central Parking and Terminal B Garage, which they do not. Cut for want of a source: hotel star ratings, stated TSA queue times, walk and arrival times presented as fact (now labelled our estimate, or replaced by Massport's own advice to arrive two hours before domestic and three before international flights), unsourced peak hours and holiday sell-out windows (replaced by Massport's own: Tuesday and Wednesday mornings, February and April school vacation weeks), and 'monitored and lit 24/7' (Massport says only that attendants are on duty 24/7). Two broken sentences repaired. llms.txt now states no figures or dates and links only live pages, and a new check fails the build if that changes.
• 2026-09-29: the Economy page's visible Time budget box still told readers to expect a 5-10 minute shuttle wait, with an end-to-end time and peak-hour windows built on it, and credited it to Massport's shuttle page, which publishes no interval for Route 88. The earlier fix to the same claim in the page's structured data had missed it. The box now says Massport publishes no interval, and the build fails on any stated shuttle wait.
• 2026-09-29: the structured data that search engines and AI assistants read, but readers never see, brought into line with the pages. FAQ answers on 16 pages had drifted from the visible answers, including a 5-10 minute Economy shuttle wait Massport does not publish; they now repeat the visible answers word for word, and 27 questions that appeared nowhere on their pages were cut, among them shuttle frequencies for all three off-airport lots and whether Terminal E parking is open. Business and terminal descriptions now repeat each page's opening text, and unsourced opening hours, payment types and a site search that does not exist were removed. Two broken sentences on the Economy page, left behind when a shuttle interval was cut, were repaired. A new check fails the build if structured data ever says something its page does not.
• 2026-09-29: the park-and-fly page's hotel parking claims read at the hotels' own pages. The page said all three hotels include parking for 'up to 14 days' in a secure garage. Wrong for both hotels we could read: Embassy Suites' Park, Stay, & Go covers one night plus parking for up to 7 nights, valet only, and the Hilton publishes no park-and-fly package, only Park & Stay, which covers the nights you stay. The Hyatt's site blocks automated reading and Massport's hotel page says nothing about parking, so the page now says we could not read it. Unsupported lines about free cancellation, sell-out timing, a day-5 break-even and oversized-vehicle surcharges were cut. Corrected on the park-and-fly page and the homepage, and registered.
• 2026-09-27:Massport's Central/Terminal B and Economy rate cards and the advance reservation rate re-read first-party in a browser ahead of the 1 October scheduled check. Every tier and the lost-ticket fee match the dataset exactly; nothing corrected and, pending Matt's ruling on the visible 'Verified' stamps, nothing re-dated. The Terminal E roadway construction alert had already been taken down by Massport and is removed from the site. The park-and-fly page's 'Free 24/7 shuttle' for the Hyatt and Embassy Suites was unsupported: Massport describes the Hyatt shuttle as limited-service, and Embassy Suites publishes a shuttle every 30 minutes with no hours. Both corrected.
• 2026-09-26: five statements no source supports, cut on Matt's ruling: a Gold Parking Express card-delivery promise on the valet and long-term pages, the holiday page's December 2024 sell-out statistic and its $3 valet surcharge, the park-and-fly page's '47% Discount' badge, and two hotel shuttle travel times. A source note on the valet page claimed Massport's terms promise card delivery in 7-10 business days; they do not, and the note now records what the terms do say.
• 2026-09-24: every page swept for published prices, fares, hours, frequencies, addresses and third-party terms, and the registry that watches them grew from 27 facts to 75. Corrected: the long-term page stated a Route 88 interval of 15 to 20 minutes, which Massport does not publish, and the long-term page and homepage gave an off-airport shuttle frequency, one of them attributed to a Massport page that says nothing about off-airport operators.
• 2026-09-18: the first sourced pass of the Alternatives page, and the Terminal E airline list completed. Wrong and corrected: a $12 Logan Express fare that exists at no location (every location publishes $9 online), and that $9 published as 'fixed' when Massport marks it a limited-time offer; Framingham's and Woburn's timetables, wrong in opposite directions; every Logan Express journey time, none of which Massport publishes; Blue Line hours, wrong at both ends and on Sundays; the water taxi's price, journey time, hours and 'seasonal' label; and two statistics with no locatable source. Taxi and rideshare prices have no published source at all, so the page now labels them our estimate. Terminal E's airlines were read across all four of Massport's pages.
• 2026-09-13: airline-to-terminal assignments read first-party from Massport's airline list, filtered per terminal. A, B and C are complete; E is explicitly partial because Massport paginates it, so the E card says 'including' and never implies a full list. This closes the one gap left open when the terminal modules first shipped without airlines.
• 2026-09-13: all three off-airport operators re-read first-party. PreFlight publishes every 7-10 minutes with real-time tracking, confirming the shuttle-frequency withdrawal made on 2026-09-11 was correct. Park Shuttle & Fly and Park N Boston publish a free 24/7 shuttle and NO interval, so every 'every 5-10 min' style claim about them was unsupported. All three remain quote-only with no published daily rate. Amenities, loyalty schemes, security and operator guidance captured per operator rather than generalised. MBTA fare also cleared: $2.40 one-way, verified first-party, plus the 1 September 2026 two-hour unlimited-transfer pilot.
• 2026-09-13: V2.1 truth pass. All Massport facts re-read FIRST-PARTY in a browser (curl returns an Imperva JavaScript shell with no rates). Terminal and Economy tiers UNCHANGED from 2026-09-02 and now re-dated. Corrections made: Logan Express named Peabody and was stale, Massport now lists Danvers and five locations, parking is $7/day not free, $9 online fare is flagged limited-time, Back Bay is $3 with a free return. Added: all six on-airport shuttle routes, with the finding that Massport publishes NO Route 88 headway, so the legacy 'every 15-20 minutes' claim is unsupported. Added: parking-status page renders 'Last updated on null EST' with no facility statuses, so there is no live data path and nothing on this site may be labelled live availability. Added: current operational alerts including Terminal E roadway construction 9/14-9/29 and the Runway 9-27 closure through the fall. DOCUMENTED CONFLICT: the handoff's cited 'open lot in front of Terminal E' sentence was not present on the cited Massport accessibility page today.
• 2026-09-02: first scheduled run had never fired (nothing scheduled it); run by hand. Every Massport dollar figure unchanged; Massport relabelled its tier rows only. Park Shuttle & Fly $120/$165/$230 were found to be car-detailing packages, not monthly passes - removed here and from both live pages. 6DAYFREE expired 2026-08-31, removed. All three off-airport operator pages re-read; every other claim still matches. Massport advance-reservation $29: Imperva blocked the script, confirmed by reading massport.com/logan-airport/getting-to-logan/parking/terminal-parking in a browser the same day.

Money, and how it is kept away from the rankings

Some links on this site earn us a commission and every one of them is marked. Massport links never do, and never will: they are the honest reference and the reason to trust the comparison. A commission has never decided which option we put first, and the comparisons on this site routinely recommend Massport’s own garages, which pay us nothing. Our disclosure page names exactly who pays us.

Tell us we are wrong
