A bit of feedback: - There's no https (not even on the signup page), which isn't really ideal in general and especially not if it's a site which is probably being used through open airport wifis or in coffee shops waiting for the next flight. - The button on the signup page (http://airportcat.com/signup http://airportcat.com/signup) isn't consistent with the other buttons - Personally I think the yellow font on the pictures makes it all look a bit "cheap" and it's hard to read. - The check in feature is a good idea but I'm not sure if it'll get used a lot, there are already Foursquare and Facebook and you can only use so many check in apps at once. Maybe integrate these other services somehow? Not sure if that's possible with their API. - The localisation isn't choosing the closest airport for me, it should be MUC but it's using FRA. Apart from that I like it and I'll probably add some tips myself.
