There are better (comparing prices) platforms i used several times this platform - especially for air tickets) but the prices that appeared after the search were not the same when i clicked and redirected in the formal sites. I think that there is also a collaboration with skyscanner that i stopped use it for the same reasons.
This is a travel website that offers comparisons between different airlines, and also other travel services. I recently used them when booking my trip to Disney and was able to find the lowest prices on airline tickets by going through their website instead of hopping around all over the place. Plus I didn't have to book through them, I just can find the prices and book through the airline directly unlike hotwire or other discount travel sites.
