For a partner flight to credit to AS, the flight must be Marketed and Operated by the partner airline. As per the details, a BA flight will only credit if it falls within the specified flight numbers. The two-letter BA airline code must precede the flight number on your ticket. For example BAxxxx. If the flight is marketed by another airline such as AA and bears a code-share on the ticket it is not eligible for credit to AS but can be credited to AA.Therefore, BA52 from SEA-LHR marketed by BA and operated by BA is eligible for credit to AS while the same flight AA6232 marketed by AA and operated by BA is not eligible for credit to AS. To see Qualifying flight information on the AS website click the "Details" below the "Earnings" to see eligibility. For an Example, I have included the qualifying information for BA flights here.
