mileage

MileagePlus is the loyalty program of United Airlines and Aeromar that offers rewards to passengers traveling on certain types of tickets. Following the 2011 merger agreement between United Airlines and Continental Airlines, United Mileage Plus was chosen to be the frequent flyer program for the combined airline. The program was subsequently renamed to MileagePlus, and maintains its relationship with its Star Alliance partners, as well as other airline and travel enterprise agreements.
Following the integration and phase out of Continental OnePass on March 3, 2012, MileagePlus also became the frequent flyer program for Copa Airlines and Copa Airlines Colombia. The new program member IDs follow the OnePass format (2 letters + 6 digits) in lieu of the old Mileage Plus format (11 digits), and any members who had existing OnePass member ID numbers retained their existing numbers. In March 2015, Copa Airlines announced that it would phase out the MileagePlus program in favor of a new frequent flyer program called ConnectMiles.
