Yes, you can bring sunscreen in your checked baggage without any of the volume restrictions that apply to carry-on bags. While carry-on items are strictly limited to 3.4 ounces (100ml) per container, checked bags have no such limit, allowing you to pack full-sized aerosol cans, large family-sized pump bottles, or high-volume lotions. However, there are some practical tips to keep in mind: aerosol sunscreens must have a cap to prevent accidental discharge, and since cargo holds undergo pressure changes, it is highly recommended to place your sunscreen in a sealed Ziploc bag to prevent a "lotion explosion" over your clothes. In 2026, many travelers are also mindful of "Reef Safe" regulations; if you are heading to Hawaii, the US Virgin Islands, or Palau, ensure your sunscreen does not contain oxybenzone or octinoxate, as these are banned to protect coral reefs. Packing your sun protection in checked luggage is the most efficient way to ensure you have enough for your entire vacation without the hassle of TSA liquid limits.
