- Emergency landings: Private planes that experience an emergency mid-flight and need to land in Cuba for safety reasons may be allowed to refuel.
- Humanitarian flights: Private planes carrying humanitarian aid to Cuba may be allowed to refuel.
- Special licenses: The U.S. government may issue special licenses to certain private planes allowing them to refuel in Cuba for specific purposes, such as medical evacuations or cultural exchanges.
In addition to these exceptions, Cuba has also established several designated airports where foreign private planes are permitted to land and refuel, subject to certain conditions and fees. However, it's important for American citizens and entities to comply with all applicable U.S. laws and regulations regarding travel to Cuba and to seek legal guidance before planning a flight to the island.
