ATLANTA -- Computer problems caused long lines at check-in counters at AirTran Airways for the second day in a row.

The airline installed a new computer system that has been causing the problems.

AirTran officials thought they had the problems solved late Tuesday night, but the computer glitches resurfaced today.

Lines at AirTran counters at Hartsfield-Jackson International Airport snaked out the terminal as frustrated fliers waited hours to check in for flights.

Yesterday some travelers reported waiting in line more than six hours.

Because of the computer problems agents have been forced to write boarding passes by hand.

AirTran is suggesting travelers print out their boarding passes before leaving home or arriving at the airport three hours before their flight.
