Hi all, I wouldn't doubt that this topic has been discussed before; I promise I did thorough searching before posting this thread, I couldn't find a previous one!

I want to find all available fare classes and their respective prices for every particular flight on US-based carriers. Does anyone know if there's a resource for that? In other words, if I'm going to fly US from CMH-CLT-RSW and I want to know the B, H, and Y fare prices for that one-way trip on a particular date, is there a resource I can tap to figure that out?

I know DL has a reasonable system on their own online RES that's decently reliable for figuring this stuff out, and I think CO has one too, but I don't think US does. I didn't know if there was a third party site...something along the lines of Seatcounter.com BUT INSTEAD of listing how many seats are in each fare class, it lists the price(s).

Thanks in advance for the help!
