Lawyers and consultants involved in Delta Air Lines Inc.'s bankruptcy case are asking for another $32.8 million in fees and expenses primarily covering four months of work. A hearing on the requests by 23 different firms and individuals is scheduled for Aug. 22. If approved, it would bring the total amount of professional compensation allowed so far in the case to $74.2 million. That total doesn't include money requested by certain firms that have not yet been paid and money held back from Delta's auditor on a previous pay request. Atlanta-based Delta, the nation's third-largest carrier, filed for Chapter 11 protection in New York in September 2005. It has said it expects to emerge from bankruptcy within the first half of 2007, which would mean before the end of June.
