If you are short on luggage space to get all the snacks in just get a moving carton. Depends on what you are taking a small one will usually do. Just pack it and keep it unsealed and they will close it , after taking a peek , at the airline desk. I bring my own tape. Sometimes we use a friend's condo and i just tell them it is stuff for the condo. I just make sure everything that can break is in a baggie and that there is something in there to cushion. It will come out with the luggage after your flight.Have fun on your trip!
