Decided to build a new flight booking engine using some AI to weed out the garbage flights the airlines and meta-sites throw at us.
Wanna help me test it? Put your name in the Google Doc below and I'll let you know when I put it into production.

Not seeing Southwest flights is a downside but everyone is at this disadvantage from what I can tell. It's not a huge deal; if Southwest doesn't fly directly between the two cities, you are better off finding another airline.
Something I do want to see is something that combines Google Flights results and tools (flexible airports and dates) along with Skiplag's results. Google has a nice interface and great tools but Skiplag has that extra intelligence that helps you with one-way tickets.
I recently booked some flights to Europe to meet up with friends. I didn't want to fly their itinerary since it had gone up in price by a lot so I used Google Flights to find other European cities I could fly to and then fly from to meet up with my friends. My dates were flexible and both my origin and destination were flexible. I just needed to get to Europe as cheap as possible (getting around Europe is relatively cheap) and be in the right city on a certain day. One feature that would be good to have is a way to create a larger itinerary that involves round-trip tickets. Google Flights does all one-way tickets when you try to do a multi-city trip.
One interesting thing to have would be some sort of metric on how well the airline is performing. I originally booked a flight to Brussels on Wow Airlines. Imagine my surprise when they went out of business a week later and weren't offering refunds to Americans. Being able to see a small red flag that says "Hey, this airline is going bankrupt" would be pretty handy.
