So I am again left scratching my head regarding why I should see such different prices depending on what my initial search criterion was for class of service.
This one definitely looks like a bug, although I have no idea where the error comes from. It should be showing you $12624 for F instead of $3489.
Other than this, though, I think everything else you're seeing is consistent: the price is $1873 in Y, $3489 in W, unavailable in J and $12624 in F. (If you search for W, it shows you $3489, not $2500.)
