Long lines and frustrated travelers aren't uncommon these days at airports, however, it's worse when it happens around a holiday.
Travel plans for hundreds of United Airlines passengers at Chicago's O'Hare International Airport were grounded, Thursday, after a computer glitch took out the airline's ticketing system.
People looking forward to spending the Fourth of July with family and friends saw their flights cancelled and delayed as United staff had to check in passengers manually.
"I think they should have different lines for different hours-- departures together," one passenger suggested.
To complicate matters, O'hare's computer problems affected other airports with connecting flights to and from the nation's second largest airport - which also serves as a hub for United Airlines.
The glitch also kept pilots from knowing how many passengers were boarded and how much weight the planes were carrying - which impacts fueling the aircraft.
