I wanted Oct. 19th Kochin to Denver. The only thing the agent could find was economy COK-DOH-MUC-ORD-DEN (even though on my screen it showed Business class available, though it did involve an overnight in DOH which I was ok with). I did spoonfeed the agent the details of what I was seeing, but she still claimed she could not see it. I spent hours searching online before making the phone call.
I initially did book the above itin, but then decided to book the single connection DXB-IAD-DEN. Still economy but I think should be more bearable than the other option. Even when I called back to change it, the 2nd agent could not see what I was spoonfeeding from my screen.
