BOS: Runway Work Triggers Another FAA Ground Delay at Logan

BOSTON, Massachusetts — November 8, 2026 — Construction on Boston Logan International Airport’s airfield set off another FAA ground delay program on Saturday, November 7, holding Boston-bound flights at their origin airports for about 70 minutes on average. It came one day after storms pushed average arrival delays at Logan as high as roughly 144 minutes.

What happened

Saturday, November 7: The FAA ran a ground delay program for Boston arrivals, citing runway and taxiway construction. It was scheduled from about 1:00 p.m. to 9:59 p.m. ET, with an average assigned delay of about 70 minutes.
Friday, November 6: A separate weather-related program had average Boston arrival delays of about 144 minutes at one point.
Logan stayed open throughout. No full closure was announced.

Why Logan keeps slowing down

Massport has limited Runway 9-27, Logan’s main east-west runway, since August 31, 2026. Crews are installing an Engineered Material Arresting System (EMAS), a crushable safety overrun, at the end of Runway 27. This is the second phase of a two-year project and includes a deck over Boston Harbor. The work does not lengthen the runway.

With 9-27 out, traffic is squeezed onto Logan’s five other runways. Weather days hurt most. On September 29, construction delays averaged 86 minutes and more than 40 flights were cancelled.

Confirmed reopening date	TBA
Airlines and terminals	All Logan arrivals are exposed; no terminal changes reported

What it means for non-revs

Expect delays to stack up on bad-weather days until 9-27 is back. Check the FAA’s NAS Status page and your airline’s app before you list for a Boston flight.
Delays mean misconnects, and misconnects fill seats. When inbound flights run 70 minutes or more late, revenue passengers get reaccommodated onto later Boston flights, which can push you down the list.
Avoid tight connections through Boston, especially international-to-domestic. Give yourself a buffer or route through another hub.
Have a backup. Providence (PVD) and Manchester (MHT) are alternatives if Boston loads look full.
Carry on. Long ground holds and rebookings raise the risk of being separated from a checked bag.
Thanksgiving watch: Massport aims to finish before the holiday, but no firm reopening date has been published. If the work runs late, holiday loads and construction delays could overlap.
