Delta Air Lines Inc. was expected to file notice Monday, June 19, that it intends to terminate its pilot pension plan, the latest step in the Atlanta-based airline’s bid to complete its reorganization by mid-2007.

The expected move was telegraphed in a letter airline CEO Gerald Grinstein sent to U.S. congressional leaders. The bankrupt air carrier said it plans to terminate its pilot plan effective Sept. 2, but hopes for legislation that it says could preserve the pension plans covering other employees.
