Cuba Travel Alert 2026: Foreign Office Warns Against All but Essential Travel Amid Severe Power Crisis

For years, Cuba has been a bucket-list destination, famed for its vintage cars, rhythmic salsa, and sun-drenched beaches. However, in February 2026, the music has quieted as the island faces one of the most significant energy and logistical collapses in its modern history.
On February 11, 2026, the UK Foreign, Commonwealth and Development Office (FCDO) officially upgraded its travel advice, warning British nationals against all but essential travel to Cuba. This rare and serious escalation comes as the island grapples with a nationwide power grid failure and a critical shortage of aviation fuel that has grounded hundreds of flights.
A Nation in the Dark: The Power Grid Collapse
The primary driver behind the new travel warning is the “severe and worsening disruption” to Cuba’s essential infrastructure. The island is currently experiencing persistent nationwide power outages, with some regions left without electricity for more than 24 hours at a time.
These blackouts aren’t just an inconvenience for tourists; they are a systemic failure affecting:
- Water Supply: Pumps rely on electricity, meaning water shortages are now common even in major cities like Havana.
- Communications: Mobile phone networks and internet access are intermittent as towers lose power.
- Health Services: While major hospitals have generators, the FCDO warns that medical care for travelers may be compromised.
- Food Safety: Prolonged outages are affecting refrigeration, leading to concerns over food spoilage in restaurants and hotels.
The Aviation Crisis: No Fuel at the Gate
Perhaps the most shocking development for travelers is the “Aviation Fuel Blackout.” On February 9, 2026, Cuban authorities issued a Notice to Air Missions (NOTAM) stating that Jet A-1 fuel would be unavailable at all nine international airports until at least March 11, 2026.
This has caused immediate and widespread chaos for airlines:
- Cancellations: Carriers like Air Canada, WestJet, and Air Transat have suspended all operations to Cuba effective immediately, affecting over 400 weekly flights.
- Technical Stops: European airlines, including Air France, Iberia, and Air Europa, are continuing some services but must make technical refuelling stops in third countries like the Dominican Republic or the Bahamas on their return legs.
- Tankering: Some short-haul airlines are “tankering”—carrying enough fuel from their departure point for the entire round trip—which significantly limits the number of passengers and luggage they can carry.
The Human Impact: Beyond the Resort Gates
It’s easy to look at travel warnings as a list of logistical hurdles, but for the people of Cuba and the travelers currently there, the situation is deeply personal. British tourists on the ground describe a “pervasive anxiety.” While many large resorts in Varadero and Cayo Coco are utilizing solar power and heavy-duty generators to keep the lights on for guests, the surrounding communities are struggling.
The FCDO has urged those currently in Cuba to “carefully consider if your presence is essential.” For those who choose to stay, the advice is stark: conserve mobile phone charge, stock up on bottled water, and be prepared for ground transportation to simply stop as fuel rationing at petrol stations becomes more stringent.
What This Means for Your Booking
If you have a holiday booked to Cuba in the coming weeks, the FCDO’s “against all but essential travel” advisory is a critical turning point for your consumer rights:
Travel Insurance: Most standard travel insurance policies are invalidated if you travel against FCDO advice. However, the update typically triggers the right to claim for cancellation if your trip was booked before the warning was issued.
Package Holidays: If you booked through a UK tour operator (like TUI or a specialist agency), they are generally required to offer a full refund or an alternative destination if the FCDO advises against travel.
Flight-Only Bookings: If your flight is still operating (e.g., via a European hub) and you choose not to go, you may not be entitled to a refund unless the airline cancels the flight.
Looking Ahead: Will Stability Return?
Industry experts, including Cuba specialist Matthew O’Sullivan, suggest that while this is a “turbulent” moment, it could be the catalyst for necessary change. Currently, the crisis is exacerbated by regional geopolitical tensions and secondary sanctions that have choked off oil supplies from traditional partners.
For now, the “Pearl of the Antilles” is in a state of suspended animation. The Cuban government is working to stabilize the grid, but with aviation fuel supplies not expected to normalize until mid-March at the earliest, the message to travelers is clear: Wait.
The beauty of Havana’s Malecón and the white sands of Varadero will still be there, but 2026 has reminded us that even the most beautiful destinations are vulnerable to the realities of energy security.
