If you're stuck at O'Hare International Airport in Chicago this morning, you have our sympathy.

All United Airlines flights there have been grounded because of problems with the airline's computers, the Associated Press says. It says there are "long lines in the terminal" ('ya think?).

United attributes the mess to a "check-in system issue" at the airport. It says there are "some delays and cancellations."

United has also announced that a "travel waiver" has been issued for those scheduled to travel through Chicago. That means "you can reschedule your travel" through EasyCheck-in Online.

We like this tweet from "kvandebunte": "At O'Hare with a bazillion magazines."

She may have time for them all.
