Staff at Denver International Airport made the announcement on the loud speakers shortly after midnight local time, saying computers were slowly coming online. A flight to Washington, D.C.'s Dulles International Airport was being prepared for departure.
Thousands of flyers were stranded Friday night in airports across the country when the airline's computers crashed, interrupting departures and reservations and disrupting the airline's website.
The airline confirmed the problem on Twitter. United spokesman Charles Hobart said the computer problems started at about 7:15 p.m. CDT. He did not elaborate on the nature of the problem.
