I'm booking a flight from HNL to PHL. I want to stop over in San Fran on the way back. Both online AND on the phone with a United rep I get a fare of $620 (without the stop-over) .

Booking online, when I read the rules, they state that 2 stop-overs are permitted, one in each direction, for approximately $59 each. But, the only way I know to add a stop-over is by choosing multi-city. And then, the fare skyrockets to about $800.

On the phone w/ a United CSR I'm able to book the original fare of $620 and get the one stop-over, with a total fare of about $690. Of course, I have to pay the CSR for the privilege of speaking w/ him.

Same dates, same flights - still not possible to get the lowest fare on united.com .

Is there something I'm missing or doing incorrectly?

Many thanks,
Aloha
