I've seen this a couple of times myself; once was on a Go flight to Stansted (ah, memories...) which was packed with rowdy schoolkids coming back from a jolly to Italy. Raptuous applause after landing from said kids, although the approach was very turbulent so perhaps they were just glad to be down in one piece!
The second time was on a charter flight a couple of years ago, Britannia MAN-VCE. It was early in the season and packed with very distinguished elderly couples going on holiday for a bit of P&Q. I was as surprised as anyone when they started clapping after touchdown at VCE, although I have to say it was a supreme landing
