If you fly from Minnesota (MSP?) you will definitely have a connection. Regent uses TK, QR, AU, EY often and all nice airlines TK if you fly the 789. I just used miles for my Trip QR DFW-DOH-CPT with a 4 hr layover in DOH (perfect for shower and a meal in a nice airport) and then returning QR JNB to DOH 3 night stopover and DOH-PHL-DFW on AA. You will have lots of choices there.
