Why Airlines Are Pulling Back From Cuba

The short version? Jet fuel.

Cuba’s aviation fuel shortage is part of a much larger energy crisis that has been building across the island. The country has long depended on imported oil, especially from Venezuela, and disruptions to that supply have created a ripple effect that now reaches well beyond power outages and gas lines.

For airlines, that creates a very practical problem. Airports need reliable fuel. Airlines need predictable operations. And when either of those things becomes uncertain, carriers start making very unromantic decisions very quickly. Cuban airports have issued fuel warnings affecting major gateways including Havana, Varadero, Santa Clara, Holguín, Cayo Coco, Camagüey, Santiago de Cuba, Cienfuegos, Manzanillo, and Cayo Largo. That means flying to Cuba can suddenly require fuel tankering, technical stops, schedule changes, or outright cancellations.

In other words, this isn’t just about one airline having a bad month. It’s about whether Cuba can reliably support international air service at scale.

Which Airlines Have Suspended Flights To Cuba?

The list has been growing.

Several major airlines have suspended, reduced, or adjusted Cuba service because of fuel shortages and operational uncertainty, including:

• Air Canada

• WestJet

• Air Transat

• Iberia

• Air France

• Turkish Airlines

• Rossiya

• Nordwind

Canada has been hit especially hard because Cuba is such a major winter sun destination for Canadian travelers. Air Canada suspended Cuba service and organized return flights for travelers already on the island, while Air Transat and WestJet also pulled back. For vacationers who had booked what was supposed to be a straightforward beach trip, the disruption turned into a scramble of reroutes, refunds, and changed plans.

European and long-haul airlines have a harder puzzle to solve. A short flight from Miami can carry extra fuel much more easily than a long-haul route from Madrid or Paris. That’s one reason U.S. routes have been more resilient, while European service has been more vulnerable.

Iberia has now suspended its direct Madrid-Havana route from June 1 through October 24, 2026, with passengers offered options to change dates, reroute, or request a refund. The airline is aiming for a possible return in November, but that depends on conditions improving.

Are U.S. Flights To Cuba Still Operating?

Yes, and this is where the story gets a little more complicated.

U.S. airlines including American Airlines, Delta Air Lines, and Southwest Airlines have largely maintained service to Cuba, though some routes and frequencies have been reduced. The reason is partly geographic. A flight from Miami to Havana is short enough that aircraft can depart with enough fuel to complete the round trip or reach an alternate airport without relying heavily on refueling in Cuba.

That doesn’t mean the trip is effortless. It just means the plane can get there. For American travelers, the bigger issue is still legal and logistical. U.S. citizens and residents can’t travel to Cuba for pure tourism. Travel has to fall under one of the authorized categories, such as family visits, journalism, religious activities, humanitarian projects, educational activities, professional research, or support for the Cuban people.

So yes, Cuba is still reachable from the U.S. But reachable and easy are not the same thing.

What Travelers Need To Know Before Booking Cuba

This is not the moment to treat Cuba like a low-effort beach escape. Travelers should expect more uncertainty than usual, especially around flight reliability, ground transportation, power outages, hotel operations, and access to basic services. Some hotels have reportedly consolidated guests or temporarily closed, and daily life on the island has been affected by the broader energy crisis.

Cash is also essential. U.S.-issued credit and debit cards generally don’t work in Cuba, so travelers need to plan carefully before arrival. Travel insurance is required, and Americans should keep documentation showing their authorized reason for travel.

There’s also an important ESTA note for international travelers. Travelers who have visited Cuba may no longer be eligible to enter the U.S. under the Visa Waiver Program and may need to apply for a visa instead. That doesn’t mean they can never visit the U.S., but it can make future U.S. travel more complicated. Basically, Cuba is still possible. It just isn’t casual right now.

Should You Book A Trip To Cuba Right Now?

Taking a trip to Cuba now depends on what kind of traveler you are. If you’re picturing an easy resort week where everything runs smoothly, this may not be the moment. Cuba’s fuel shortage, flight suspensions, power outages, and broader economic strain make it a risky destination for travelers who need predictability.

But if you’re an experienced traveler, understand the legal requirements, book flexible flights and hotels, carry enough cash, and go in expecting disruption, Cuba remains one of the most fascinating places in the Caribbean. It’s beautiful, complicated, culturally rich, and unlike anywhere else. The key is not pretending this is a normal travel year.

Iberia may return in November if conditions improve. Other airlines may do the same. But for now, Cuba’s shrinking flight map is a clear sign that travelers should plan carefully, read every booking condition, and leave room for things to change.

Yes, though some routes and frequencies have been reduced. American Airlines, Delta Air Lines, and Southwest Airlines have largely maintained flights to Cuba, especially from Florida. U.S. carriers are better positioned to manage the fuel issue because the routes are much shorter than long-haul flights from Europe.

Why is Cuba running short on jet fuel?

Cuba’s jet fuel shortage is tied to the country’s broader energy crisis and disruptions to imported oil supplies. Aviation fuel shortages have affected multiple Cuban airports and forced airlines to cancel flights, reroute, tanker fuel, or add technical stops.

Can Americans legally travel to Cuba in 2026?

Yes, but not for pure tourism. Americans must travel under one of the authorized categories, such as family visits, journalism, religious activities, educational activities, humanitarian projects, professional research, or support for the Cuban people.

Generally, no. U.S.-issued credit and debit cards don’t usually work in Cuba, so travelers should bring enough cash for their trip and understand the currency situation before arrival.

Iberia has suspended its Madrid-Havana route from June 1 through October 24, 2026. The airline is currently pointing to a possible return in November, depending on conditions.

Is Cuba safe to book right now?

It’s possible, but risky without flexibility. Travelers should choose refundable bookings when possible, monitor airline updates closely, carry cash, confirm travel insurance, and be prepared for disruptions on the ground.

Should travelers wait to visit Cuba?

Travelers who want a simple, predictable vacation may want to wait. More experienced travelers who understand the rules and are comfortable with uncertainty may still find Cuba worth visiting, but this is a destination that currently requires extra planning.
