Hey! yep this is databaseless at the moment. Although I think I'm gonna have to bit the bullet on that soon if I want to have some user accounts and the ability to "save" or "watch" a certain trip...
performance wise it's really just the APIs that are slow (specifically the flights) - and there's nothing really I can do about that apart from caching maybe - and even then I don't think it's gonna be that effective.
And no sorry I'm keeping this code private for the moment so it's not open for contribution. Feedback and suggestions are more than welcome though of course! :D
