Does anyone know if the lowest round trip fare class on YYZ or HKG to Doha is B? I tried searching HKG-DXB-DOH in oppose to HKG-DOH and it would only price in B as well. I am pretty sure they have lower ones available if booking a ticket out of Doha. A round trip HKG-DOH costing USD 3000 sounds outrageous.

Any suggestions on how to book it?
