The Washington Post is reporting Delta is back in the air. They have lifted the ground stop and the computer system is back up and running. Although delays and cancellations are still expected.
Fox Business said earlier this morning, Delta Air Lines passengers all over the world were stranded due to a system-wide computer crash.

The Atlanta-based airline announced that all Monday morning flights were grounded because of the outage.

Delta still says all passengers need to check the status of their flights before arriving at the airport, and they expect large cancellations until they catch up to the backlog.
