When jetting off on holiday, being on the plane itself is often the least stressful part of the experience after going through security and rushing to the gate. Beyond watching the flight safety demonstration, most passengers will go into their own world and watch films, listen to music or read a book.
For those without headphones in, different chimes can be heard over the intercom system throughout the flight. One American cabin crew member has explained what all the sounds mean - and there's one we never want to hear.
Tommy Cimato posted a TikTok explaining all the chimes passengers can hear throughout the flight. He said: "Have you ever heard these sounds on a plane before? Do you ever wonder what that means?"
