According to the BBC, the nationwide grounding orders caused by a technical glitch in the US air traffic control system have been lifted, but the ripple effects are extending into the weekend: on Sunday, over 5,000 flights were delayed and 2,000 canceled. US Transportation Secretary Sean Duffy stated that it will take time to realign mismatched aircraft and crews, and normal operations may not resume until Monday. This is an expectation for recovery, rather than an announcement that things are back to normal or a guarantee of a full recovery by Monday.
