I want to purchase a QR ticket and make a one day stopover in Doha on the way to my final destination but I can't seem to find a way to do it through the QR app. The multi-city section on the app allows for just two segments, making it impossible for me to book my return flight. The reason I want to book through the app is because it allows me to pay for the ticket using a mix of cash and avios. When booking through the website, this option does not exist. Anyone know if there is a way to book a stopover through the app?
