United Airlines has resumed flights after a computer failure halted flights out of Chicago, Crain’s Chicago Business reports. The airline also had 481 flight delays Sunday.
"We have resolved the issue and flights are resuming,” Maddie King, a spokeswoman for United, told Crain's. "Customers may experience additional delays as we work to get flights out this evening. We apologize for the inconvenience to our customers."
United has issued a travel waiver for customers originally scheduled to fly January 22 - 23. The change fee and any difference in fare will be waived for new flights departing on or before January 25, 2017, as long as travel is rescheduled in the same cabin (any fare class) and between the same cities as originally ticketed, United said.
According to CNBC, the ground halt was lifted at approximately 9 p.m. Sunday evening. International flights were not affected.
