American, Delta, JetBlue Secure Waivers to Cut Cuba Flights

Three major U.S. carriers—American Airlines, Delta Air Lines, and JetBlue Airways—have received approval from the U.S. Department of Transportation (DOT) to temporarily reduce flight schedules to Cuba. The decision, granted on March 13, 2026, comes in response to a critical aviation fuel shortage and deteriorating infrastructure on the island, which has led to a significant decline in passenger demand.

The regulatory approvals, known as Summer Season Dormancy Waivers, allow the airlines to suspend numerous routes through October 24, 2026, without forfeiting their long-term rights to the frequencies. The move underscores the severe operational challenges facing airlines serving Cuba, forcing a significant capacity reduction from the U.S. market and impacting travel for the large U.S.-based Cuban diaspora.

The Scope of the Service Reductions

According to DOT filings, the approved waivers cover a substantial portion of the U.S.-Cuba air corridor. The specific cuts include:

• American Airlines: The carrier received waivers for 14 daily US-Cuba flights, a significant reduction that includes eight daily round-trips between its key hub at Miami International Airport (MIA) and Havana.
• JetBlue Airways: The airline gained approval to waive 20 weekly flights connecting Fort Lauderdale and Havana.
• Delta Air Lines: Waivers were granted for two daily Miami-Havana services and one daily round-trip between its Atlanta hub and Havana.

The service cuts are a direct response to official alerts from Cuban aviation authorities. A Notice to Air Missions (NOTAM), published via the U.S. Federal Aviation Administration (FAA), confirmed that Jet A1 fuel is unavailable at 10 Cuban airports. This notice is currently effective through at least April 4, 2026, creating an untenable situation for carriers that rely on local refueling.

In its DOT filing, American Airlines highlighted the broader issues, stating that "Current infrastructure challenges in Cuba warrant flexibility." The airline referenced a U.S. embassy alert that noted Cuba's "national electrical grid is increasingly unstable and prolonged scheduled and unscheduled power outages are a daily occurrence."

Industry-Wide Impact and Operational Workarounds

The fuel crisis is not limited to U.S. carriers. Several major international airlines, including Air Canada, WestJet, Air Transat, and Air France, have completely suspended all flights to Cuba due to the inability to refuel aircraft. This widespread withdrawal of service is severely impacting Cuba's tourism sector, a critical source of hard currency for the nation's economy.

For airlines that continue to operate flights to Havana, such as Southwest Airlines, new operational procedures have been implemented. A Southwest spokesperson confirmed the carrier is now engaging in fuel tankering—requiring aircraft to carry enough fuel for the outbound and return legs of the journey. "Due to the current status of aviation fuel in Cuba, Southwest Airlines is requiring aircraft that fly to Havana to carry enough fuel to also fly to their next destination," the spokesperson noted.

This situation is reminiscent of historical precedents where economic crises have crippled a nation's aviation infrastructure. During the Sri Lanka Aviation Fuel Crisis in the summer of 2022, a severe national fuel shortage forced international airlines to tanker fuel or make technical stops in southern India to refuel. That event provides a direct operational parallel for the strategies now being employed for Cuba flights, demonstrating how sovereign economic distress can directly impact global airline network planning.

A Volatile Market

The U.S.-Cuba aviation market has a history of volatility. After an initial rush of service following the normalization of relations, several U.S. airlines, including Frontier, Silver Airways, and Spirit, exited the market between 2017 and 2019, citing overcapacity and weaker-than-expected demand. The current crisis, driven by infrastructure failure rather than market dynamics alone, represents a new and more severe challenge for the remaining carriers.

The impact is felt most acutely by the U.S.-based Cuban diaspora, which now faces significantly fewer flight options and likely higher fares for visiting family. Furthermore, Miami International Airport (MIA), the primary gateway for U.S.-Cuba travel, will see a notable reduction in daily departures and connecting traffic.

What Comes Next

The immediate future of air travel to Cuba remains uncertain. The critical date is April 4, 2026, when the current NOTAMs regarding fuel unavailability are set to expire. However, it is unclear if Cuba will be able to resolve its fuel supply issues by that time. The dormancy waivers granted by the DOT provide the airlines with operational flexibility through the IATA northern summer season, which ends on October 24, 2026. Airlines will likely wait for clear signals of a stable fuel supply and improved infrastructure before considering a full restoration of their suspended schedules.

Why This Matters

This large-scale suspension of U.S.-Cuba flights highlights the profound operational risks airlines face when serving markets with fragile economies and deteriorating infrastructure. The crisis serves as a stark reminder that bilateral air service agreements are only viable when supported by stable, on-the-ground logistics. For the aviation industry, it underscores the need for robust contingency planning and risk assessment, as geopolitical and economic instability can ground flights just as effectively as any technical or regulatory issue.
