The outlook for Wednesday’s operation is positive, Delta officials said, with about 90 cancellations expected at the beginning of the day leading to normal operations later.

“We continued today to steadily recover from the events of earlier this week that grounded our system, and are working hard to achieve a normal operation by mid-day tomorrow,” said Dave Holtz, Senior Vice President – Operations and Customer Center. “We will have a small number of cancellations in the morning as our operation restarts, so we continue to ask our customers to check their travel plans and flight status. We apologize to everyone who has been affected by these events, and we thank them for their patience.”

Customers traveling today and tomorrow should check the status of their flight at delta.com or the Fly Delta App. Customers can rebook their flight via the website.
