United Says Computer Tests on Boeing 757s Almost Done

United Continental Holdings Inc. said it’s almost finished with computer checkups on 96 of its Boeing Co. 757-model jets after canceling 15 flights while performing the unscheduled maintenance yesterday.

Any disruptions today will be “very minimal,” Megan McCarthy, a spokeswoman, said in a telephone interview. The “majority” of the tests on air data computers had been completed by mid-morning New York time, she said.
