TOKYO, Nov 5 (Reuters) - Japan Airlines Corp (9205.T) said it would eliminate 17 more routes to cut $78 million in costs a year and is considering further route closures as it scrambles to turn around its loss-making business.

The latest route reductions by Asia's largest airline by revenue came after it applied for assistance from a state-backed corporate turnaround body, setting the stage for a large injection of public funds into the troubled carrier.

By closing the 17 unprofitable routes, which include flights between Tokyo's Narita airport and Mexico as well as between western Japan's Kansai airport and Hanoi, JAL expects annual cost reductions of 7.1 billion yen ($78 million).

"JAL is bleeding everyday. We decided we need to do something as soon as possible," Manabu Sato, JAL deputy general manager of corporate affairs, told reporters.
