Delta Air Lines'
regional airline Comair said it resumed flights Sunday after a computer snafu grounded all its planes Saturday.
In a news release late Sunday, Comair said it will gradually ramp up operations to a full schedule by midweek. The airline normally flies 1,160 flights to and from 119 cities. The airline planned to operate only 10% to 15% of its normal schedule on Sunday.
Comair, which is wholly owned by Delta, said severe weather stressed its infrastructure and rendered the computer system that manages flight-crew assignments inoperable.
Comair said some passengers might be flown on Delta flights instead as Comair ramps up operations again. Delta's mainline flights are operating normally, the news release said.
Delta was up 4 cents to $7.60 Monday morning.
