United Airlines is to cease its seasonal transatlantic service from Shannon to Chicago from next year blaming poor financial performance on the route.

It follows the airline's recent decision to cease its daily Shannon Newark service from November to March in response to a seasonal reduction in market demand for the service, but it will resume next Spring.

Shannon Airport Managing Director Andrew Murphy said they were disappointed by United's decision to end their Chicago service next year despite their best efforts and those of Tourism Ireland to reach an agreement with the airline.

He said finding a replacement carrier for the Chicago service will be a priority and they will continue to work with United and other airline partners to provide services and access to key markets.

He said this year Shannon had its largest number of transatlantic services in 17 years with five airlines, Aer Lingus, Delta, American Airlines  Norwegian Air, and United serving seven destinations in the United States, and the recent addition of a service to Toronto.

He said Shannon remains committed to improving connectivity to the US for tourism on the Wild Atlantic Way and for foreign direct investment into the Shannon and West of Ireland region.
