I agree with AMS. I'd give it until next Wednesday before doing anything even though it's tempting to chase in the meanwhile.
The good news is that it's a Friday today and in my experience of working on an interview panel at my previous job we usually gave the news at the end of the week. Not entirely sure why but I seem to recall hearing from my current airline on a Friday after a 2 week wait.
If nothing comes though just try and have a relaxing weekend. Go for walks, see a movie etc and try to take your mind away from it. Then email Wednesday if nothing. Really very best of luck.
