Northeast airport delays this winter:
the I-95 corridor effect.
One storm shuts down five airports simultaneously. Here's the airport-by-airport winter delay data for EWR, JFK, LGA, BOS, and PHL — and how to protect your travel plans. Updated October 16, 2026.
2026-27 El Nino winter forecast
This winter is forecast to be stormier than average in the Northeast due to a developing El Nino pattern. El Nino winters typically bring more nor'easters and mixed precipitation events to the I-95 corridor, which means more ground stops, de-icing delays, and cancellations at the five major corridor airports.

The I-95 corridor effect
The five major Northeast airports — Newark, JFK, LaGuardia, Boston Logan, and Philadelphia — are packed into a 300-mile stretch along the I-95 corridor. They share overlapping airspace managed by New York TRACON and Boston Center, and they share connecting traffic.
When a winter storm moves up the coast, it doesn't hit one airport — it hits all of them in sequence. Philadelphia gets it first, then the three New York metro airports, then Boston. Because they share airspace, a ground stop at Newark cascades to JFK and LaGuardia within minutes. Because they share connecting passengers, delays at one hub strand travelers at the others.
The result: a single nor'easter or ice storm can simultaneously disrupt airports that collectively handle over 500,000 passengers per day. No other region in the U.S. has this level of concentrated vulnerability.

Worst winter weather types for flights
Nor'easters
The most destructive single-event storms for Northeast aviation. Heavy snow, freezing rain, and 50+ mph winds can shut down all 5 corridor airports for 24-48 hours. Recovery takes 2-3 additional days.
Ice storms
Worse than snow for airports. De-icing operations take 3x longer with freezing rain. Runways can't be plowed — they need chemical treatment. A half-inch of ice can close an airport for a full day.
Heavy snow
Accumulation rates above 1 inch per hour overwhelm snow removal crews. Runways need plowing every 15-20 minutes. De-icing queues stretch to 90+ minutes. Capacity drops 50-70%.
Low-visibility fog
Winter radiation fog forms on clear, cold nights. Reduces airport capacity by 30-50% because closely-spaced parallel runways (like SFO and EWR) can't operate independently in low visibility.
Connection advice for winter Northeast travel
Avoid connecting through Northeast hubs in winter
If you're flying coast-to-coast, a connection through EWR or JFK doubles your winter storm exposure. Choose a Midwest hub (ORD has its own issues) or a southern hub (ATL, CLT, DFW) when nonstop isn't available.
Build buffer days into winter trips
A 2-day storm recovery means your Sunday return flight might not operate until Tuesday. If missing a day of work isn't an option, fly back a day early during December through February.
Book morning flights
First flights of the day have the highest on-time rates because the aircraft is already at the gate (no inbound delay risk) and cascading delays from earlier flights haven't built up yet. Before 10 AM is the sweet spot.
Monitor proactively
Check FAA.gov/flysafe for ground stops and GDPs before leaving for the airport. Your airline's weather waiver page will have free rebooking options 24-48 hours before major storms.
Know your refund rights
If the airline cancels due to weather, you're entitled to a full cash refund — not vouchers, not credits. This applies even to non-refundable tickets under 14 CFR Part 260.

Common questions
Which Northeast airports have the worst winter delays?+
Newark (EWR) consistently ranks worst for winter delays in the Northeast, followed by LaGuardia (LGA) and JFK. EWR's New York airspace constraints amplify every delay, while LGA's shorter runways close earliest during crosswinds and snow. Boston Logan (BOS) is often the storm center for nor'easters but has better snow removal infrastructure.
How does one snowstorm shut down 5 airports at once?+
The I-95 corridor airports — EWR, JFK, LGA, BOS, and PHL — share overlapping airspace managed by New York TRACON and Boston Center. A single storm system moving up the coast hits Philadelphia first, then the New York metro airports, then Boston. Because these airports share airspace and connecting traffic, a ground stop at one cascades to all five within hours.
Is this winter expected to be worse than average for flight delays?+
The 2026-27 winter is forecast to be stormier than average in the Northeast due to a developing El Nino pattern. El Nino winters typically bring more nor'easters and mixed precipitation events to the I-95 corridor, which means more ground stops, de-icing delays, and cancellations at EWR, JFK, LGA, BOS, and PHL.
What should I do if I have a winter flight through the Northeast?+
Book morning flights (before 10 AM) to avoid cascading afternoon delays. Choose nonstop flights to eliminate connection risk. Monitor FAA.gov/flysafe for ground stops before leaving for the airport. If a storm is forecast, use your airline's weather waiver to rebook for free before the storm hits — waivers are posted 24-48 hours in advance.
