American and Aer Lingus have announced the addition of 2 new routes to add to their codeshare agreement.

The news comes around 18 months after the carriers — both part of the Atlantic Joint Business Agreement — initiated a codeshare agreement to enhance cooperation.

Here’s what you should know.

American and Aer Lingus Codeshare: The Details

The codeshare between American and Aer Lingus means, in a nutshell, that passengers can book a trip that includes flights on either airline on a single ticket, making transit and the entire travel experience far more seamless.

When the codeshare was originally launched, it allowed passengers to book transatlantic flights on American Airlines from both Charlotte (CLT) and Dallas-Fort Worth (DFW) to Dublin directly on aerlingus.com. Now, the agreement has been expanded to provide the same functionality in Chicago (ORD) and Philadelphia (PHL), a major upside for those traveling frequently between the U.S. and Ireland.

As we said above, this change makes for a more streamlined travel experience for passengers who can now book journeys on a single ticket and check bags through to their final destinations, even if the journey involves travel on both airlines.

As an added bonus, Dublin is a U.S. Customs and Border Control Preclearance facility, which means flyers pass through U.S. customs and immigration before departing from Dublin. This exempts flyers from having to collect any checked baggage and then re-check it for an onward domestic flight within the U.S.

The Aer Lingus/American Airlines codeshare also allows customers to seamlessly book connecting itineraries between the U.S. and Ireland to and from the following cities:

Albuquerque, New Mexico (ABQ)
Kansas City, Missouri (MCI)
Las Vegas, Nevada (LAS)
Nashville, Tennessee (BNA)
Portland, Oregon (PDX)
San Jose, California (SJC)
Tampa, Florida (TPA)
Tucson, Arizona (TUS)

Final Thoughts

The addition of more routes to the Aer Lingus/American Airlines codeshare agreement is great news for travelers wishing to fly between Ireland and the U.S.

The fact that the number of routes is growing can only mean that the airlines view their codeshare as a success. With that, we expect this codeshare partnership to only grow in the future, and we should see more routes added to the arrangement in the future.
