It is still the same.
You're charged landing fees when the wheels touch the tarmac.
Having said that, I've also done touch and gos and not been charged for the privilege! (Thanks Prestwick!) So it's not black and white.
I think flying the little adour with 2 seats may help, I'm not sure you would get such an understanding Airport ops manager if you practiced your touch and gos in your new A380.
But such is life eh?
