My speculation would be that the scheduled flights were still published at the time the data was gathered. These updates are not daily to include the latest political turmoil and why should they? That would actually be detrimental, IMHO.

FWIW, just came across another interesting flight. AB7341 from POP to VRA. Trying to book the flight with Air Berlin proved to be impossible. I figure the flight is really MUC-POP-VRA, but POP-VRA vv is not on offer (I'm sure AB would like to offer seats). This creates a bit of an inconsistency in the data, but I suppose it's not possible for cockpitvisit to deal with this automatically.
