The U.S. government maintains restrictions on travel to Cuba due to the ongoing political and economic embargo against the island nation. As a result, most flights between the U.S. and Cuba are reserved for government officials, journalists, and individuals participating in specific authorized programs, such as educational or cultural exchanges.
However, it's important to note that these regulations can change over time. For the most up-to-date information on travel restrictions to Cuba, it's best to consult with the U.S. Department of State or the Cuban embassy in the United States.
