The data I'm using is from the Oneworld Timetable, so according to that, you are correct, there is only LGW-VCE service, not LHR-VCE.

I've added yet another feature.. the ability to show all OWE destinations from/to an airport, this should be quite useful in OWE itinerary planning. Eg, you can see all destinations from LHR, or all destinations from KRT, sorted by distance. This should handle (most?) direct flights as well as nonstop.

Individual flights are not displayed, just destinations.
