Hi All. Early November I will have a long day of flying....getting my 4 sectors in on AA/US to requalify. On the last day this will be my routing:

BUF - PHL US in coach
PHL - CLT AA in coach
CLT - IAD US in coach
IAD - DOH QR in business

I am currently Platinum (OWS) with AA.

I know the rules are no domestic lounge access unless it is a connection with a Oneworld international flight on the same day. But I am not sure what the case is with the above - the BUF-PHL-CLT-IAD is on one ticket and the QR sector on another ticket.

Will I be able to get lounge access (assuming there is a lounge in BUF) at all 3 airport en route, will it only be at PHL as it is the only AA sector, or only at CLT as it is the last stop to connect to IAD or none of the above.

Thanks

W
