U.S. commercial flights from Cuba will happen anytime soon as several airlines began submitting applications to new routes.

Working quietly behind the scenes, U.S. airlines have already started preparations for commercial trips to the island nation as soon as the travel restriction that has been standing for half a century long in Cuba is lifted.

In a report by Travel Pulse, the U.S. State Department has announced last week that the two countries had made arrangements to reopen commercial flights between them. Furthermore, the State Department stated that the resumption of commercial air travel between U.S. and Cuba will "continue to allow charter operations and establish scheduled air service, which will facilitate an increase in authorized travel, enhance traveler choices and promote people-to-people links between the two countries."

Several U.S. commercial air transport companies including American Airlines have announced their intention to apply for a service contract with the government which will grant them access for commercial trips to Cuba. In addition, the air carrier has already started expanding flights from Los Angeles to Montego Bay, Jamaica; Dallas to Punta Cana in the Dominican Republic and Grand Cayman; and Charlotte -- its second largest hub -- to Puerto Plata also in the Dominican Republic and Curacao.

JetBlue, which presently operates around 145 flights daily from Fort Lauderdale-Hollywood International Airport (FLL) to Latin America and the Caribbean, has also made public their latest non-stop daily flight trips beginning May 5, 2016 between Rafael Hernandez Airport (BQN) in Aguadilla, Puerto Rico and FLL.

According to Beacon Examiner, JetBlue will complete its application to the U.S. Department of Transportation for new routes to Cuba once it has certainty on the timing and process of designating frequencies to U.S. airline companies.

Senior Vice President for airline planning, Scott Laurence, said the company was thrilled about the possibility of commercial flights to Cuba and will likely process routes from Tampa International Airport, Orlando International Airport, FLL, JFK International Airport and Newark Liberty International Airport.

However, it is yet unclear when commercial flights from the U.S. to Cuba would start as talks between U.S. airlines and the Cuban government could take a while.

In other related news, American Trade Journal reported JetBlue's (JetBlue Airways Corporation) shares increased by 3.41 percent over the past week but on a 4-week basis dropped 7.49 percent.

JetBlue, a passenger airline, operates mainly with its fleet of 49 EMBRAER 190 aircraft and 120 Airbus A320 aircraft on point-to-point routes including Puerto Rico, Mexico, 12 countries in Latin America and in the Caribbean and 70 destinations in 22 states.
