I like the UI it provides to find the solution for the problem "I want to travel from near City A to near City B some time around November, and I don't want to spend too much." Specifically, I like the "calendar of lowest fares" view. I also like the ease of inputting advanced search parameters. If you're going to use it to make a list of flights Google Flights is usually better.
