Most people call the things they carry with them on a trip "luggage", however, we usually call everyone's luggage "baggage"...We call the men who move the luggage between planes "baggage handlers" and the conveyor belt you collect them from the "baggage claim". I hope that made sense haha. The other common use of "baggage" is: Something that holds you down/back, something that impedes your emotional, mental or physical freedom. Examples: "We don't lack the capacity to change, we just can't move under our emotional baggage." "I have too much baggage right now to move on." "I've got too much baggage in my house...It's time to do some cleaning. "Wait for me! I'm just going to grab this lamp..." "Leave the lamp, you already have too much baggage."

There is no difference in the words. Put your things in "bags" (baggage) and "lug it" (luggage) to your destination. Okay, I just made that up.

Hello everyone! What about saying the things in this way: we can buy our luggage but not our baggage.

You can use both words.

Nope, no difference at all!
