NEW YORK, Sept 10 (Reuters) - JetBlue Airways ( JBLU )

said on Wednesday that it will expand its service in rival

Spirit Airlines' main market of Fort Lauderdale, Florida, with

nine new nonstop routes across the United States, Latin America

and the Caribbean.

The company said it is reinforcing its presence at the airport

as airlines rush to cash in on rival Spirit's second bankruptcy

filing in less than a year.
