Hey Lorathon,
I was just thinking that your addon (already excellent) would benefit from a feature (or set of features) which allow a pilot to enter their departure (initial) airport and the arrival (terminal) airport. If there is no direct flight it should populate with an itinerary of interconnected flights which would start from the departure (init) airport and end at the arrival (terminal) airport. for example if i wanted to travel from LGAV to KIAD and there was no direct flight it should give me an itinerary of flights that are operational by the VA like
LGAV (Athens, GRE) to KJFK
KJFK to KIAD
it will enhance the sence of realism in the VA as far as booking flights don't you think?
