United Airlines said computer malfunction that compelled passengers to line up Thursday outside the United Airlines terminal at O'Hare International Airport, has over.

The computer outage remained from about 3 a.m. to 10:30 a.m. local time, forcing delays and hundred cancellations at O’Hare, the world’s second-busiest airport for passenger traffic.

Speaking on the topic, Robin Urbanski, a united spokeswoman, said, “We are essentially back to normal operations.”

However, United was still advising customers on its Web site to check in online instead of at the airport.

Passengers also faced problems as the lines were on the increase in the terminal as new flights arrived and departing flights were unable to leave.
 
Last year, about 69.4 million passengers passed through O’Hare.

In the recent trading, United Airlines recorded a rise of 2 cents to $3.31 in Nasdaq Stock Market trading in New York.

In the meantime, Delta Airlines announced it would cut capacity by 10 percent this year, while AMR plans to trim down its capacity by 7.5 percent.
