yeah, we need to fix or warn about that better. the reason that the airline searches don't work reliably is that most airlines only serve a few airports, and if you search for airports they don't serve, the result is not always handled gracefully. some airlines prompt for a known airport - some just give up and display an error. to counter this, we would need to maintain a list of all airports served by each airline, and only let users launch valid searches to the airline sites. i think that is good from a usability perspective, and it's definitely doable, but maintaining it is time-consuming. that's why we haven't done it yet. but, we may well get to it soon.
