Booking problem on certain websites
 

Does anyone know how to get around this problem?

When I am booking FC reservations on expedia, orbitz or other airline websites. It often does not allow me to see all the options because some of those begin with a segment on a regional jet. Many airports have the majority of flights on regional jets meaning my search for flights becomes severely limited. I am yet to figure a way around this except by checking coach prices and then calling in to book the FC reservation. I realize the web site is trying to do me a favor by showing me that part of it is not in FC, but at least allow me to have the option to select it.

Thanks in advance if anyone knows how to get around this problem and have all flights appear regardless of equipment.
