Try looking at
www.flyertalk.com
A whole forum dedicated to flying experiences, getting the most out of your airline mileage, hotels, etc.
www.seatguru.com is also a good site to make sure you don't pick the "wrong seat" as well as seeing what facilities they have on board.
BTW, if you're flying strictly within the US, try some of the low cost airlines for some better deals, especially if you're flying a lot. Frontier, Southwest, Allegiant, JetBlue are some suggestions. Frontier flys into Vancouver in the summer, and Allegiant flys out of Bellingham for two suggestions that are close to Vancouver.
