BUSINESS BRIEFING

US Airways, Union Reach Accord

US Airways reached a tentative contract with its machinists union that would give it a unified contract for thousands of fleet-service workers, the airline said.

The contract is subject to ratification by union members.

Delta Raises Ticket Fees

Delta Air Lines doubled the fee for buying tickets through its reservation agents to $20 and added as much as $25 to fees for other services.

The charges are part of an effort to steer customers to Delta.com, which charges no added fee, spokeswoman Betsy Talton said. The fee for voluntary ticket changes and to redeem frequent-flier awards within 20 days of departure is now $75, up from $50.

BANKRUPTCY

Fees May Increase

Companies in Chapter 11 bankruptcy protection would pay significantly more in quarterly fees to the federal government, in some cases triple what they're paying now, under a budget proposal set to take effect next year. The U.S. Trustee Program, a Justice Department office that monitors consumer and business bankruptcy cases, has proposed a 30 percent fee increase. It also wants to triple the fees for the biggest companies. The proposal has been approved by the full House and by Senate budget leaders.

Lender Files for Protection

HomeBanc, a mortgage lender, filed for bankruptcy protection two days after saying it would sell assets to Countrywide Financial. Atlanta-based HomeBanc listed assets of $5.1 billion and debt of $4.9 billion in Chapter 11 documents.
