Delays Expected After United Airlines Flights Grounded Nationwide

All United Continental flights in the U.S. were grounded temporarily Wednesday [July 8] due to computer problems.  Less than two hours later, United requested the Federal Aviation Administration lift the ground stop order, FAA spokesman Lynn Lunsford said. The Federal Aviation Administration issued the ground stop alert due to an "automation issue". About 3,500 flights were affected, NBC News reported. 

It is the second time in two months that the Chicago carrier has been hit by major technical issues. United Continental Holdings Inc. had a temporary halt to all takeoffs in the U.S. on June 2 because of what the airline said were computer automation issues.
