Does anyone know if there is a website that you can go to that if you put in your destination and dates it would show you all of the possible types of ff fares and carriers...supersaver, premium, usair, airfrance, etc for that flight? thank you

I like to use www.kayak.com for comparison shopping. It will show you all airlines and fares, but not ff mileage awards. For those I go directly to the website of the airline on which I have ff miles.

Every time I've booked FF tickets I've had to call to get the ticket. They could find a seat that didn't show up on the airlines web site.

I'm assuming your question regards one site where you can see award availability for different carriers?

Is so, no. Each airline, with a few exceptions, may allow you to book FF award seats on-line, and there are a few that will show you availability on some (not all) partner airlines, but there's no omnibus site where you can see availability on non-partner airlines or just browse in general.

A couple of paid services like expertflyer.com allow you to view some award inventories on some carriers using the "hidden" booking codes (e.g. upgrade availability on American Airlines) but as a rule only members of airlines' FF programs can see award inventory on those airlines that do post it, and only after signing in.
