The UK government has issued an urgent travel warning after authorities revealed that all international airports in Cuba are currently without aviation fuel, triggering widespread disruption to flights and raising concerns for tourists.

In an emergency update, the Foreign, Commonwealth & Development Office (FCDO) warned British travellers that the Caribbean island is facing a rapidly worsening infrastructure crisis, including severe power outages and fuel shortages that are now affecting international travel.

The department said the situation is already impacting the ability of visitors to move around the country and access essential services.

“Cuba is experiencing severe and worsening disruption to essential infrastructure, persistent power outages across the country and fuel shortages,” the FCDO said in its latest advisory.

“These conditions are significantly affecting the ability of visitors to access reliable transport, medical care, communications, and basic services.”

Cuban authorities have confirmed that aviation fuel shortages mean international airports across the country are currently unable to operate normally, forcing airlines to cancel services or review routes, Birmingham Live reported.

Some flights are being diverted to alternative terminals or hubs as authorities attempt to manage the crisis.

At Jose Marti International Airport in Havana, Terminal 2, which normally handles flights to the United States and some charter routes, has been closed, with services redirected to Terminal 3.

Several airlines have already suspended services altogether.

Air France has confirmed it will suspend flights between Paris and Havana from 29 March until 14 June, with the last scheduled departure from Havana to Paris Charles de Gaulle set for 28 March.

Meanwhile, all Canadian airlines and LATAM have already halted flights to and from the island, while other carriers are reviewing whether to continue operating routes.

The Foreign Office warned the disruption could worsen quickly, potentially leaving travellers with fewer options to leave the country.

“Options for leaving the country could reduce further if the situation worsens,” the advisory states.

“The situation has the potential to deteriorate quickly and without warning. Make sure you are ready to change your plans quickly if needed.”

The crisis has been triggered by a wider national energy shortage, with Cuban authorities introducing fuel rationing and scaling back public services across the country.

According to the FCDO, the government has also implemented temporary changes to healthcare, education, transport and tourism operations in an effort to conserve limited energy supplies.

British tourists currently in Cuba are being advised to closely monitor updates from airlines and tour operators, and to ensure their travel documents remain valid in case they need to leave the country quickly.

Travellers have also been warned to take practical precautions due to ongoing shortages.

“If you are currently in Cuba, carefully consider if your presence is essential,” the Foreign Office said.

“Take precautions by conserving fuel, water, food and mobile phone charge, and be prepared for significant disruption.”

The warning comes as thousands of British holidaymakers visit the Caribbean island each year, particularly during the spring and early summer tourism season.

Officials are urging anyone planning travel to Cuba in the coming weeks to check airline updates carefully and remain prepared for further cancellations or delays as the fuel crisis continues.
