- You cannot accrue partner airline miles with your partner frequent flyer number if you have already used your AAdvantage® number to obtain AAdvantage®program benefits such as First or Business Class upgrades, baggage fee waivers or complimentary access to Preferred/Main Cabin Extra seats. Additionally, you cannot redeem partner airline miles with your partner frequent flyer number and obtain AAdvantage® program benefits such as priority boarding and access to preferred seats.
