United Continental Holdings Inc.’s Continental Airlines will cut about 500 jobs at the carrier’s Houston offices between April 1 and June 30, the Houston Chronicle reported Monday, citing a letter from Continental to the Texas Workforce Commission.

Around the time of its Oct. 1 merger with United Airlines to form the biggest U.S. carrier, Continental said it would continue to employ its Houston-based management and administrative workers through March.

Continental  is operating as a United subsidiary until the Federal Aviation Administration approves a joint operating certificate, expected later this year.

A Continental spokeswoman told the Chronicle that the cuts will have “minimal impact on front-line employees” such as pilots, flight attendants, gate agents and other airport personnel.
