Departing passengers waited in long lines at London's Gatwick Airport on Saturday after a computer glitch forced airline staff to write out boarding passes by hand, AP reported. Airport operator BAA said the problem began late Friday night and affected all carriers except British Airways. Airlines brought in extra desk workers, but check-in lines were moving slowly because they had to write out boarding passes and paperwork manually. One or two flights leaving the airport south of London were delayed by up to an hour, but otherwise departures were not affected, BAA said.
