It might not be a good idea to take a coffee maker in carry on luggage. The way airports are with their security measures it might be a better idea to put it in a checked bag. My sister had a pair of little nail clippers taken away before and the last time she and her family flew they had to empty the entire contents of their camera bag out and take off all of their shoes, including the babies, who was only a year old, and ended up missing the plane because it took so long to get through security. Better safe than sorry, just pack something soft, like a dish towel, inside the carafe, than wrap it well in plastic.
