Logan Runway Closes Aug 31: What Fall Flyers Should Do

If your fall travel plans run through Boston Logan International Airport, mark August 31 on your calendar now. Massport, the Massachusetts Port Authority, confirmed this week that Runway 09-27, one of Logan's main runways, will close for approximately 75 days starting that date, with work expected to wrap up before Thanksgiving. That window swallows Labor Day weekend, the Columbus Day and Indigenous Peoples' Day holiday, the heart of New England's fall foliage season, and the run-up to Thanksgiving travel, which together make up some of the busiest and most weather-exposed weeks Logan sees all year. The closure is not routine maintenance, it is a safety upgrade. Crews will install an Engineered Material Arresting System, known as EMAS, at the end of Runway 27. EMAS beds use a lightweight, crushable material that is designed to safely stop an aircraft that overruns the runway during a landing or aborted takeoff. Logan already has EMAS systems protecting Runways 22R and 33L, and this project extends that same protection to 09-27. Massport spokesperson Samantha Decker described it plainly: this is a critical safety project that requires closing a major runway, so some reduction in capacity, and the delays that can come with it, should be expected. The work involves building a pile-supported deck that extends partly over the water, plus a temporary jet blast deflector, and construction is limited to daytime hours, so this is genuinely a multi-month undertaking rather than something that can be rushed. Why should a traveler care about one runway among several? Because Logan's runway configuration is what lets the airport keep multiple planes moving in different wind conditions and weather patterns. With 09-27 out of service, the airport has fewer options when a nor'easter, a summer-style thunderstorm line, or just a stiff crosswind rolls through, and traffic that would normally spread across more runways gets funneled onto fewer. Massport's own warning is specific: expect delays during inclement weather, air traffic restrictions, or other operational disruptions. Limited departures for smaller narrow-body aircraft, think Boeing 737s and Airbus A320s, may still be possible from Runway 27 when conditions allow, but that is a partial workaround, not a full substitute for the runway's normal capacity. Logan handles more than 1,000 arrivals and departures a day across 45 airlines serving 156 destinations, so even a modest percentage reduction in capacity, layered onto three separate holiday travel surges, adds up to real risk of cascading delays. So what should you actually do if you have a Logan trip booked or in mind for late August through late November? Start by treating early morning departures as safer bets than afternoon or evening ones; delays that begin building after a rocky morning tend to compound through the day, and a first-wave flight has the best shot at leaving close to on time. If you have a choice of routing, favor nonstop flights over connections through Logan during this window, since a tight connection is exactly what a reduced-capacity airport puts at risk. If your itinerary allows real flexibility, consider flying out ahead of the Thanksgiving Wednesday crush entirely rather than joining what is already the single heaviest air travel day of the year layered on top of construction-reduced capacity. For New Englanders near Boston, it is also worth knowing you have alternate airport options if a specific date looks rough: Providence's T.F. Green (PVD), Manchester-Boston Regional (MHT), Bradley International near Hartford (BDL), Worcester Regional (ORH), and Portsmouth International at Pease (PSM) all sit within reasonable driving distance and are not affected by Logan's runway work. If you are planning a fall foliage trip into New England and were going to fly into Logan as your gateway, it is worth pricing out one of these alternates, particularly if your visit lands on a weekend in late September or October when leaf-peeping traffic typically peaks alongside the closure. Practical steps for anyone already booked: turn on your airline's app notifications now rather than waiting until the day of travel, since real-time alerts will be your first warning of a schedule shift. Build extra buffer into any connection at Logan, both for your own itinerary and if you are meeting someone arriving there. Pack carry-on only where possible so a misconnection does not also mean a lost bag. And if you are dropping off or picking up passengers, arrive earlier than you normally would, since ground congestion tends to track flight congestion during stretches like this. None of this means Logan is shutting down or that your trip is doomed. Airlines and Massport have managed phased runway work before, including an earlier phase of this same EMAS project last year, without major network-wide disruption. But going in with realistic expectations, and a bit of extra schedule padding, is the difference between shrugging off a delay and missing a connection during one of the busiest 75-day stretches New England air travel sees each year.
