On the return from my first trip to South Africa I carried 12 bottles of wine in my luggage.
That was back when flights included two free checked items.
On my second trip to Europe one of my suitcases was full of T-shirt swag to give out at a conference. Lugging both up the stairs, across the train tracks, and back down was a hassle.
Both of these were over 20 years ago.
And then there's the story at https://notalwaysright.com/a-steam-powered-cruise/392530/ of a couple trying to bring a full-size espresso machine on their cruise, so they can have their special coffee.
