If you are planning a car trip or plane trip for an extended vacation, it is best to invest in sturdy luggage. These are larger and can be packed with all of your necessities without fear of damage. Whether packing for the car or plane, these need to be kept in good condition. Always check the zippers, handles, and material for signs of stress and wear. Keep in mind that this luggage may also have to withstand more abuse than other types.
For aircraft travel, try to pack lightly since many airlines charge by the pound for checked luggage. A small carry on bag is generally allowed on the airplane, but recently there have been new regulations for carry on bags. Checking with the airline in advance may save you money, since many things not allowed are thrown in the garbage. Having a small carry on bag is convenient but not if you have to waste your supplies.
