I think it is great what you are doing. Of course, this is what travel search should be like. Though, I'm genuinely curious, what are you really trying to achieve? Sure, more flexible nice is great. But it is definitely not a killer feature. Low price seems to be key when it comes to mass air travel. As far as I can tell from the responses, all you do is show fares from airline aggregators (I also got a timeout when I tried). Is this really a viable business model? I'm sure they will eventually come around to offer the same search features that you have. In the meantime, there are already many competitors that offer improved search interfaces (e.g. skyscanner.net, which I have used for my last trip). How are you differentiating yourself from these services? Also, while I think that improved search is needed, I would suggest reconsidering which aggregators you include. For my last trip, I found a great fare on cheapoair.com (through skyscanner), but at the last moment, I was having second thoughts, and decided to google them. Well, to say the least, they do not appear to have a very good reputation. Similar with edreams. But I never booked with them, so perhaps, they are not as bad as some of the online reviews suggest. However, one thing that's pretty vexing is that they often will advertise a fare, but then when you go to there site, and try to book it, it is no longer available. I know that you're just providing their data, but as far as I'm concerned this is a major annoyance. Just yet another reason that makes me doubt your current business model is viable. Not to mention that you are up against sites like travelocity, which is essentially owned by the airlines themselves...would love to hear your side of the story, though!
