Delta teams have addressed a technology issue that affected customers’ ability to book, check in and board. We apologize to our customers for the inconvenience they are experiencing as we work quickly to return our operations to normal. While we expect flight delays to extend into the evening at some of our busiest domestic hubs due to this issue and weather, we do not expect any technology-related flight cancellations.
