Boston

Problem: Boston Logan International Airport (BOS) is under an active FAA Ground Delay Program averaging 70 minutes today, following over 255 flight delays and 16 cancellations entering Monday.

Why it matters: Ongoing construction on Runway 9/27, which began October 1, has severely reduced the airport's hourly arrival and departure capacity, so any minor wind shift or cloud ceiling triggers mandatory FAA metering and long tarmac holds.

Advice: Avoid tight connections through Logan this week since midday and afternoon delays are almost a daily certainty, monitor your inbound plane in your carrier's app, and if your connection window drops below 45 minutes, ask a gate agent to rebook you on a direct route or through a different hub.
