They can grow up to 4 1/2 feet <--- thats roughly 115 cm I think(bigger or smaller depending on your corn). Average thickness about an inch but again depends on your corn. Mine female is very thin in comparison to others its age.
If you want to travel check first if the country allows snakes in. Some places have quarantine so if its a short holiday there would be no point taking your snake, it would get stressed with all the travel. Snakes would be kept in a special hold that other animals are transported in.
