United, Continental boost fares $10 per round trip

DALLAS (AP) - United and Continental are raising some U.S. airfares by $10 per round trip.

Airfare experts said that as of midday Friday, other airlines had not matched the higher prices.

The airlines face sharply higher costs for fuel, 1 of their biggest expenses. They have pushed through at least six broad price increases this year, but the last two in March failed when some airlines declined to go along.
