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.
