U.S. airlines

Boeing's 737 Max 10 faces a new certification delay over a software problem, coming just as the planemaker was in the final stages of winning approval to begin deliveries to airlines. The variant has already been years in the making, and the setback pushes back its entry into airline service once again.

Air travel across the United States was heavily disrupted, with more than 1,400 flights delayed and 249 canceled, according to NJ.com. The disruptions affected passengers nationwide, though the report did not detail a specific cause. Travelers are advised to check with airlines before heading to airports as delays continue to ripple through schedules.
