Mileage Plus will become the frequent flier program for the merged United Continental, the company said on Wednesday.
Continental's OnePass loyalty program will end on December 31 and members of that program will be automatically enrolled in Mileage Plus with their award miles being transferred as well. Customers who are members of both OnePass and Mileage Plus will be able to link their accounts.
"Moving to a single loyalty program is a significant milestone in the integration of the two airlines and will provide a more consistent travel experience for customers," the company said in a statement.
United Continental said it will announce details of Mileage Plus, such as elite levels and qualifications and benefits in the coming months.
