Traveling with a stroller- help

Hi ladies

I’m having my first baby soon and my husband and I travel alot. I was wondering how does it work really to travel with a stroller? Do you give them the stroller at the door of the airplane and pick it up at the door once you reach your destination? Or you have to put it with the luggage?

I have the uppababy vista stroller so I’m worried if it gets lost or ruined during the flights.
