The Mr Fog Max 1000, like most disposable vapes, is generally allowed by the TSA in carry-on luggage but not in checked baggage. According to TSA guidelines, electronic smoking devices, including vapes and e-cigarettes, must be carried in your carry-on bag and not placed in checked luggage due to fire risk. The device must also be turned off during the flight and cannot be used or charged onboard. Always check with your airline before traveling, as individual carriers may have additional rules regarding vape products.
