As long as you are an Air China “Phoenix Miles” member, you can accrue miles when flying on any Star Alliance member flight as long as the fare is eligible for mileage accrual. Additionally, you are able to redeem miles for travel with any of the Star Alliance member carriers. This offers our frequent flyer members the ability to book multicarrier, multi-segment award travel on a single ticket, therefore offering more options and greater flexibility. Once you have achieved the required level of mileage, you would be qualified for Star Alliance Gold status, which means that you can enjoy unique recognition and rewards across all member airlines.
