The decision comes soon after Qatar Airways said it wanted to buy up to a 10 percent stake in American.
Here is American’s full statement:
In light of our ongoing dispute over the Open Skies agreements, American Airlines notified Etihad Airways and Qatar Airways on June 29 of our decision to terminate our codeshare relationships. Given the extremely strong public stance that American has taken on the ME3 issue, we have reached the conclusion that the codesharing relationships between American and these carriers no longer make sense for us. This decision has no material financial impact on American and is an extension of our stance against the illegal subsidies that these carriers receive from their governments. We are committed to doing everything we can to continue to support our team members and ensure that there is fair competition between American and the Gulf carriers.
