A couple of comments. 1. It is not immediately obvious to someone visiting the website for the first time what the + and - icons do. Seasoned users might notice something different, click on it and realize, but it would be nice to advertise your new feature. 2. When choosing flexibility, almost always I click on a date that is most suitable to me and from there on would like to navigate to more flexible dates. If I choose a date x and would like to search flights on x-1, x, and x+1, I would have to change the date to x-1 and then choose +2 or choose x+1 and then choose -2. That might be slightly inconvenient, but not much. It would be nice to allow you to choose days ahead and behind independently. That way I choose a date, realize I could be flexible and maybe choose +2 days and -1 days (or whatever).
