If this was once a topic in the past, please direct me to it.

I am trying to make a reservation that contain both international and domestic flights in business class (first in the domestic portion).

SEA-NRT-HNL-SEA (via SFO)

I used the multiple cities and put the cities and dates in the appropriate blanks and choose "Business Class." The ual.com says "No qualifying flights" for the HNL-SEA portion. I am guessing that it is because there is no business class service in the domestic portion. If I try it in economy class, no problem.

What I want to accomplish is to book SEA-NRT-HNL in business class and HNL-SEA in first (domestic) class.

Do I have to call the agents?

Thanks.
