United Continental flights in the U.S. were temporarily grounded Wednesday morning due to computer problems – a glitch that affected flights in Sacramento.
Less than two hours later, United requested the Federal Aviation Administration lift the ground stop order, FAA spokesman Lynn Lunsford told The Associated Press.
United said Wednesday that it is working to resolve lingering problems from the shutdown, which was related to “network connectivity.”
It is the second time in two months that the carrier has been hit by major technical issues.
