Alaska Airlines have an exception to standard baggage charges for the following item: Pineapple from Hawaii - one properly packaged box of pineapples when traveling within the United States from Honolulu (HNL), Kona (KOA), Maui (OGG), or Kauai (LIH)
What does such a box of pineapples look like? Does that only mean that they should not fall out of the box while transported, or are there specific requirements that a properly packaged box must meet?
