SERVICE TO DELTAKINGSTON, Jamaica - Air Jamaica and Delta Air Lines have an agreement linking their passenger and cargo services between several U.S. cities and the Caribbean.

Under the pact, Air Jamaica will provide service to Delta passengers from U.S. cities to Montego Bay, the Jamaican airline's hub, and then to other Caribbean countries.

Delta will reciprocate, starting June 1, by offering seats on its flights to Air Jamaica.

''This is a win-win situation for Delta and Air Jamaica,'' said Robert Coggins, Delta's executive vice president for marketing. ''This gives us access to new destinations.''

This is the first reciprocal code-sharing agreement between Air Jamaica and any airline, said Chris Zacca, Air Jamaica's chief executive.

The airlines will cooperate in marketing their freight and passenger services to achieve greater efficiency, according to company spokesmen.

Air Jamaica is now privately owned after its sale by the Jamaican government. It flies routes to several cities, including New York, Philadelphia and Los Angeles.
