Due to a quirk in the way some of my tickets are booked by my TA I may be flying PHL-DOH-GOI in coach with each leg on a separate ticket. It's a ~14 hour stopover at DOH, and there's only 1 flight per day PHL-DOH and DOH-GOI so no issues with shorter alternate connections. The fare will also be over the price minimum.

Is STPC allowed on separate tickets in situations like mine?
