Thanks very much for your replies. Found the above data on http://www.seatmap.com/ concerning one of my flights on Saturday 05-24-03.
I assume the numbers indicate the seats remaining to be sold in each fare class (Y = full-fare coach; F = first), but other than these assumptions, do the letters directly correspond to the fare paid (ex. B is better than Q and Q is better than T)?
