I've travelled for work all my life, I've flied idk, hundreds of times, my luggage got lost exactly one time, when I got a connection in Switzerland, they left it on the tarmac. Luckily it was my toolbox, not my personal bag.

Another time my luggage lost me, meaning they loaded it on an earlier flight and then cancelled mine, so my luggage got to destination and I didn't. That was on a flight from Miami to New York.
