NEW YORK — R.H. Macy & Co. Inc. plans to seek bankruptcy court approval of a six-month extension of its exclusive right to file a Chapter 11 reorganization plan.

The formal request is expected to be filed this week in bankruptcy court here. Macy’s has already reserved a Feb. 22 hearing date.

The extension would push back Macy’s deadline for filing its reorganization plan until Sept. 15. The plan is currently due March 15.
