FORT WORTH, Texas (AP) _ American Airlines will expand its international route system next year with daily service between the United States and five European cities.

The company said Thursday the expansion would increase American's European operations to 119 flights a week serving 13 destinations.

The airline expects to carry more than 1 million passengers between the United States and Europe this year.

''American is rapidly becoming one of the largest and strongest competitors in the trans-Atlantic marketplace,'' said Richard A. Lempert, American's vice president for international operations.

The company's new daily, nonstop service begins May 1 between Chicago and Stockholm, Sweden, and between Lyon, France, and Kennedy Airport in New York.

On May 11, the airline begins daily, nonstop service to Brussels, Belgium, from both Chicago and New York. The Chicago flight will continue to Dusseldorf, West Germany, and the New York flight will continue to Hamburg, West Germany.
