The wine must be safely packaged for transport in a protective shipping container (wine shipping box/they are cardboard or styrofoam). The TSA asks containers not be sealed, but remain open for inspection. Shipping boxes are available at many of the wineries, wine shops and shipping providers such as U-Haul. They may vary in price. Please note it is the responsibility of the Alaska Airlines passenger to be sure the wine is properly packaged for checking as luggage. Advise the Alaska Airlines Customer Service Agent when you check in so the box can be properly labeled with FRAGILE stickers. Items packaged in cardboard boxes are covered in case of loss, but are checked at your own risk for damage. View Alaska Airlines’ Checked Baggage Policies for more details.
