On all the sites I have been checking, it seems there are only a couple of different 'search engines' that check rates....it seems the different travel sites have all looped into one of only several different ones, making it easier to have 'universal rates'.

I am not sure if this is the case, it just seems to be my observation.

If I come up with a site that does appear to have an independant search engine for rates, I will post it here.

Thanks
