tripFiles alternatives

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.

I am always the person people look to to plan trips abroad. Coordinating though text and Google sheets was a hassle and desta plan has been a life saver
