I like it, worked well for the few tests I did, however the main form needs some small UX improvements, I chose a start airport and destination airport but then the search button was disabled, leaving me clueless about what field was not filled out correctly, I quickly noticed it must be the date field, but still to me disabling a submit button of a form seems like a bad idea because if disable it you also remove the display of potential error messages related to the form failing validation, which to me is a UX no go (take my opinion with a grain of salt, I'm not a UX guy). The second thing that bothers me is that none of the form fields actually tells you which ones are mandatory and which ones are not
