I’m trying to book LON-DOH-DXB-LON flights for June.

On QRs website it lets me search and quotes me for a multi-city itinerary with a mix of BA and QR metal.

However, when I try on BA.com it gives and error that flights couldn’t be found (I assume because BA doesn’t operate DOH-DXB). If I call BA, are they likely to be able to help?

Would rather book with BA.com as I have white a few vouchers to use!
