Travelocity's "Dream Maps" are great for finding low fares in Y. I'd love it if there were a sight that would list, say, all destinations from city X in C or F.
If I want to get from LAX to MAD, I know that C one way is $2000 on many carriers. Much better than one way LAX to LHR. I am curious as to what other cities have such low fares for C/F cabins.
