JJJ,
Very interesting, and I hadn't thought of that at all. I think my main line of thinking would be you'd have someone turn up to the airfield, maybe get a bottle of pepsi (or other such drink) from the snack bar, and go from there. The idea that you could deal with drugs and drunks didn't factor, but is very, very valid.
I guess a reasonable level of precaution could counter that (or at least greatly reduce the risk), in that as anyone who has flown commercially knows about security checks etc, the passenger shouldn't be averse to being asked a few questions and, if bringing on luggage, having it checked (though I'm not sure of the legalities of this).
With regards to friends and family etc, many want to come, but none want to pay. I guess Wingly gives you people who are happy to pay, which is why I still see it as being quite good.
I fully understand though
