News Summary: United Continental posts 4Q loss

THE QUARTER: A money-loser — $620 million worth.

THE CAUSE: Airplane paint and other spending to integrate with Continental, Superstorm Sandy's disruptions, and defecting customers.

WHAT'S NEXT: United Continental Holdings Inc. is well along in integrating the two airlines, and executives say they'll begin seeing more of the cost savings from the deal this year. United will also hold extra customer-service training for ticket agents, call center workers and flight attendants.
