Retired Delta pilots will get a larger voice in Delta Air Lines Inc.’s Chapter 11 restructuring, a bankruptcy court judge said Monday in a ruling that could complicate the airline’s bankruptcy proceedings.

U.S. Bankruptcy Judge Adlai Hardin said the retired pilots, who had no representation on a previously appointed retiree committee, deserved under law to have an official say in how Delta would restructure in bankruptcy — and how that could affect their retirement benefits.
