Delta crews work to stabilize schedule as winter storm impact shifts to Northeast US.

Operations in Detroit, Boston and New York continue to face delays and schedule reductions because of wind, frozen precipitation and icing conditions.

Normal operations are resuming in the upper Midwest following heavy snow, despite frigid temperatures now setting in at locations including Delta’s Minneapolis-St. Paul hub. Meanwhile, operations in Detroit, Boston and New York continue to face delays and schedule reductions because of wind, frozen precipitation and icing conditions.

As of midday Thursday, roughly 300 flights out of more than 4,600 were canceled as Delta teams focus on a safe reset for Friday’s operation.

A travel waiver remains for customers in the Upper Midwest through Feb. 24. Delta Thursday also issued a waiver ahead of inclement weather for Southern California airports, also for Feb. 24.

Delta’s in-house meteorologists are actively reviewing and sharing up-to-date weather forecasts with others in the airline’s Operations and Customer Center as they make decisions on whether to cancel flights in the days ahead. Canceling flights is a last-resort decision that is never taken lightly. When necessary, wee strive to cancel flights well in advance of scheduled departure to allow our customers to adjust their plans before going to the airport.

While there are challenges that come with running an airline safely through a weather system spanning nearly 2,000 miles, Delta people on the front lines and behind the scenes remain steadfast to the airline’s commitment to safety and getting customers where they need to be as quickly as possible as operations recover at impacted airports.

Customers can review our customer guide to traveling with Delta and are encouraged to keep the following in mind:

• Automatic Rebooking: If a flight is canceled, Delta will attempt to automatically rebook affected customers on the next available flight to get customers to where they’re going and minimize delays.
• Itinerary Updates: Delta will send updates on itinerary changes directly to a mobile device or by email. To enable this communication, please provide contact information at the time of booking or add it online via My Trips.
• Self Service: Customers are encouraged to download and use the Fly Delta app or visit delta.com to check their flight status and manage their rebooking with convenient self-service options.
• Messaging: As we anticipate Delta Reservations phone wait times will be longer than usual, the Messaging feature on delta.com and the Fly Delta app is a quicker way to get in touch with one of our specialists.
