TravelGap alternatives

It's very cool that you can see the reviews of the user and friends like the institutions and share your opinion. Functionality is very convenient

I fly a lot, but I'm not rich. Why is it so difficult to find cheap flights and why does it seem like airlines don't apply any logic to their fares at all? Hitlist has already saved me many hours of checking airfares online. I get notified whenever an interesting fare comes up for a destination that's on my wishlist. Hitlist works better for me than Hopper.
