American Airlines has renewed its codeshare agreement with Qatar Airways, a fellow member of the oneworld alliance.  The move comes just over two years after the pair very publicly fell out in a dispute over government subsidies. The new deal is seen as a first step in rebuilding a strategic partnership between the airlines. Following restoration of the codeshare, American will begin exploring the addition of service from the US to Doha. Doug Parker, CEO of American, said the issues that led to the suspension of the partnership two years ago have been addressed, and the carrier believes resuming the codeshare agreement will allow it to provide service to markets that customers, team members and shareholders value, including new growth opportunities.
