Composition of snack and baggage. Only singular. Snaggage is food you carry with you when going on a journey. It's also food you bring along at the airport to eat in the plane. Can also be spelled snackage, more common snaggage.
You can leave your snaggage right here. You'll get it back later in the plane.
You have it to slice your snaggage? Sorry mister, we have to confiscate it, no knifes in the plane.
Connor brought ten sandwiches with him on the train ride! Only as snaggage!
