Jet fuel shortage in Cuba forces airlines to cancel flights and send empty planes to pick up passengers

• Cuba has told airlines it has no jet fuel available.
• Some Canadian airlines have canceled flights and are sending empty planes to pick up passengers.
• Other carriers are making refueling stops in the Dominican Republic.

Cuba has warned airlines that it has no jet fuel, forcing some carriers to cancel flights, add refueling stops, or carry extra fuel.

Cuban aviation authorities issued a monthlong advisory on Monday that said jet fuel is unavailable at all of the country's international airports.

The country relies heavily on Venezuela for much of its jet fuel, but supplies have been hit by US sanctions that have constrained Venezuelan oil exports. President Donald Trump has also threatened tariffs on countries that sell oil or petroleum products to Cuba.

Because of this, the country is running out of jet fuel, and therefore, airlines cannot refuel their planes on the island.

From the US, American Airlines, Delta Air Lines, and Southwest Airlines all operate direct flights to Cuba.

American and Delta said they are operating as usual. In a statement to Business Insider, Southwest said that it was requiring any aircraft flying there to also carry enough fuel to reach its next destination.

Some Canadian airlines are canceling flights entirely.

Air Canada, which had operated 32 flights a week to and from Cuba before, said it would suspend service to the country on Monday.

It will send empty planes to pick up some 3,000 customers who have already traveled to the island. These flights will be loaded with extra fuel, although the airline said refueling stops on the return leg may also be necessary.

Canadian airlines WestJet and Air Transat also said they would operate empty aircraft to help their customers. Air Transat said it would suspend flights to Cuba until at least April 30.

Several international airlines serve Cuba, and many of them are still operating flights. However, some of these will have to stop to refuel elsewhere.

Air Europa, a Spanish airline, said its flights from Havana to Madrid would stop in Santo Domingo, in the Dominican Republic, about two hours away.

"We apologise for any inconvenience this situation, which is beyond Air Europa's control, may cause you," it said in a travel alert.

Iberia, the Spanish flag carrier, Air France, and Turkish Airlines also fly to Cuba. They did not immediately respond to requests for comment, although it seems likely the distance would necessitate a refuelling stop.
