hingey, unless he is good friends with someone in the cockpit, it's hard to imagine how you can end up in a jump seat or normal seat as a passenger in any aircraft without paying for the privilege.
Otherwise, I would be round to every airport I know to get free rides!
However, going round there an investigating is always a good start. Maybe you can meet someone that is willing to at least take you round to have a look at all the aircraft and stuff.
