What do you think when passengers applaud when the plane lands?

Major suggests this is a regional thing and it's more common on European flights.

"Italians do it every single flight, every single time. Sometimes after bad turbulence you'll get it. You understand that one -- people are just relieved to get there because they don't really understand turbulence," he says.
Malis says in the US, passengers usually only clap after a very bumpy flight.

"I guess people are surprised the plane landed, I'm not sure? Most planes do land," she says. "Personally, I think it's kind of cheesy. I think a lot of flight attendants would agree with me on that."
