News Summary: United Continental says operations are improving, despite 1Q loss

TOUGH QUARTER: United Continental Holdings Inc. lost $417 million as costs rose faster than fares.

787 COST: United's six Boeing 787s were grounded for most of the quarter, costing it $11 million.

FLYING CUTS: United is cutting flying capacity as much as 1.75 percent this year, in part because the 787 has been grounded. That's a bigger cut than it had expected.
