Most of the transit in the Northeast Corridor is shutting down.

Most of the public transit in the Northeast Corridor will not be operating Monday. One major exception is the MBTA in Boston, which will be operating all services except commuter boats, which are suspended as of the start of service Monday morning.

Check with your airline if you're scheduled to be flying into or out of anywhere between Washington and New York tomorrow. It's probably worth asking if you're flying into or out of anywhere on the US East Coast. From FlightAware's update:

1,251 flights cancelled to/from/within the US today. Most affected is Newark (EWR), with 305 cancellations today.

5,559 flights cancelled to/from/within the US tomorrow (Monday). Most affected is Philadelphia (PHL), with 1084 cancellations.

Most airlines are suspending operations this evening at DCA/IAD/PHL/JFK/EWR/LGA. Virgin Atlantic plans continue operations through tomorrow morning in/out of EWR and JFK.

Airport-specific updates:

EWR/LGA/JFK - PANYNJ is recommending that airlines cancel everything tomorrow but airports plan to remain open to the extent practical.

PHL - no operations tomorrow and not returning until mid-day Tuesday.

DCA - over 95% of flights cancelled for tomorrow

BWI - almost all flights cancelled tomorrow except for some limited morning cargo operations.

Every airline is allowing fee-free changes (and refunds in some cases) for itineraries potentially impacted by the storm. The best way to make flight changes is on airline websites; call centers are typically overwhelmed during major events.

You can also check FlightStats airport delay map, which currently lists "Excessive" delays for every airport on the US East Coast between RDU (Raleigh/Durham) and PVD (Providence).

Safe travel, everyone.
