Emirates sectors not linking up
 

So I am trying to book a return flight in y either 24 or 25th Oct from Doh to Bkk returning on 3rd or 4th Nov but it says no flights available.

if i search the sectors individually there is availability but to do this will cost me double the usual fare.

any ideas?

It is called the "married segments" phenomenon. Especially from DOH, EK flights DOH-DXB-XXX typically show much less availability than the two segments individually. One of the many tricks yield management is playing with us.
