Well, this is odd but I'm not gonna complain since the added TQPs are an unexpected bonus. Just completed a BS R/T, both segments on same PNR. Booked mid-February, so ineligible for the 2x TQP promo. Made an SDC at the airport for the return, same fare basis, same PNR, just an earlier flight. Received 2x TQP for the outbound but 1x for the return. Will be interesting to see if anyone else receives 2x for flights booked before the promo.
