Editor's note: This article, originally published Dec. 20, has been updated every day since. The most recent update, below, was published Tuesday, Dec. 27.

With constraints brought on by bitter cold temperatures, high winds and winter precipitation now moderating for much of the U.S., Delta people have been working hard behind the scenes to stabilize operations Tuesday.

That stability is expected to remain throughout the week and through the New Year’s holiday weekend.

The decision to cancel flights is never one Delta takes lightly, especially during the holiday travel season, but the safety of our customers and our people is paramount. When necessary, we strive to cancel flights well in advance of scheduled departure to allow our customers to adjust their plans before going to the airport.

Delta people are ready to assist customers in getting to their destinations as quickly as possible.

Here are three things for customers to keep in mind if their travel is affected:

• 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.

Customers are encouraged to check their flight status on Delta.com or the Fly Delta Mobile App. Customers can also get updates sent directly to their mobile device or by email with One-Time Flight Notification.
