United Airlines’ flights  were grounded across the country for hours this morning because of a computer failure.

Reports say that the computer system, based in Chicago, which calculates weight and balance for departing flights shut down. At one point this morning there were only five United flights in the air, according to several media reports.

United now reports that the system is back up and flights are back up in the air, but “delays are expected to continue throughout the day.”

Ahhh, I’d say that might be a little optimistic considering that the entire United fleet was essentially grounded for more than two hours this morning. If I were you, I’d just cancel that flight and tell your business partners you’ll  see them when United can reschedule you.
