Yes - that's as I see it. But you cannot advertise such flights generally; perhaps a note on the clubroom noticeboard stating "Anyone interested in flying to XXXX and sharing costs" would be OK - but "**** Planes fly you where you want to go. Contact nnn nnnnn for more info" wouldn't.
In the UK there is a very thin line between cost sharing and illegal public transport or illegal aerial work. The CAA are happy with cost sharing intelligently applied - but rightly very harsh on illegal public transport!
