Aer Lingus and American Airlines are launching their codeshare agreement this week, which will see traveling between Ireland and the US become more simple, easy and more convenient.
Passengers traveling with Aer Lingus will now be able to book codeshare travel on American Airlines flights from Chicago O'Hare to Albuquerque in New Mexico, Nashville in Tennessee, Dallas-Fort Worth, Los Angeles, Seattle, San Francisco, San Jose in California and Tucson in Arizona.
American Airlines will place its code on Aer Lingus flights between London Heathrow and Dublin.
Passengers can also book codeshare flights on Aer Lingus from Dublin to Amsterdam, Birmingham, London Gatwick and Manchester and from Heathrow to Belfast City, Cork and Shannon.
Aer Lingus joined the Atlantic Joint Business (AJB) between American Airlines, British Airways, Iberia and Finnair last year.
The AJB has brought significant benefits, such as lower fares and easier journeys to more destinations with better aligned schedules and frequencies, to millions of passengers since its launch in 2010.
