Hm, that explains why the flight is not there. IMVHO it doesn't make it correct. It's only an explanation of the systematics. You only search through one week's worth of data? Isn't it possible to add another week, best from a couple of month's down the road?

I hope you won't get mad at me for keeping on pointing out stuff I think is missing. It's my way of giving back, by helping a tiny bit to make the tool even greater. Today's candidate are all Sunwing flights. Thank you again for all the effort you put into this.
