Cuba Airspace Status & Restrictions 2026
FIR: MUFH (Havana) · Authority: Instituto de Aeronáutica Civil de Cuba (IACC) · Last updated: May 2026
The Havana FIR (MUFH) is operationally open and is a significant Caribbean transit corridor between the Miami FIR and Central America / South America. The defining constraint is regulatory: any flight with a US nexus (US person, US-registered aircraft, USD payment, or US-based dispatch) falls under OFAC licensing. OPSGROUP and the FAA's 8900.337 framework distinguish between overflight (generally permitted, with NAV fees) and landing (tightly licensed). Airways B646 and UB646 are exempt from the overflight permit requirement; NAV fees are still owed. Non-US carriers operate routinely. There is no EASA CZIB.
Current Restrictions
Cuban airspace is open to non-US civil aviation without restriction. European, Canadian, Latin American, and Caribbean carriers operate scheduled service to José Martí International (Havana, MUHA), Varadero (MUVR), and Holguín (MUHG). Aeroflot has historically operated long-haul service from Moscow to Havana through the MUFH FIR.
For US operators, the Office of Foreign Assets Control (OFAC) administers a licensing framework under the Cuban Assets Control Regulations. The FAA's Air Carrier Procedures notice 8900.337 describes how scheduled and charter carriers comply. Travel by US persons is permitted under twelve authorised categories (family visits, journalism, professional research, educational activities, religious activities, humanitarian projects, and similar); general tourism is not authorised. In 2025, OFAC tightened the framework affecting private (Part 91) US-registered operations, and OPSGROUP characterises this as an effective ban on most private US jet travel to Cuba.
Overflight of MUFH by US-registered aircraft remains permitted under general licence for transit purposes. Airways B646 and UB646 are exempt from the Cuban overflight permit requirement, but NAV (air-navigation) fees are still due under IACC tariff. Operators who do not arrange a payment vendor have been refused entry into the FIR or have had subsequent flights blocked. US operators must use a third-party vendor to clear both permits and fees because direct USD settlement with Cuban entities is restricted.
Recent NOTAM Patterns (last 12-24 months)
NOTAMs from the IACC over the past two years have been dominated by infrastructure and weather rather than security. Routine items include navaid outages at smaller fields, runway and lighting works at MUHA, and seasonal tropical-cyclone closures during the June–November Atlantic hurricane season. A nationwide power-grid failure in October 2024 briefly affected ATC services and airport operations across the island; generators restored service within hours.
Charter NOTAMs related to humanitarian flights and special-licence operations from the US have appeared at irregular intervals. No conflict-related NOTAMs have been issued for MUFH in the 2024–2026 period.
Major Airline Policies
American Airlines, JetBlue, Delta, United operate licensed scheduled service to Havana under OFAC framework. Service to provincial Cuban airports has been curtailed under sanctions tightening.
Per OPSGROUP (2025), most Part 91 US-registered private flights are now effectively unable to clear the licensing path.
Air France, Iberia, Air Europa, KLM, Condor, Edelweiss operate scheduled service to Havana and Varadero. No EASA restrictions apply.
Air Canada, WestJet, Sunwing — heavy seasonal traffic to Varadero, Holguín, Cayo Coco during the winter sun season.
Copa, Aeroméxico, Avianca, LATAM offer connectivity from Panama, Mexico City, Bogotá. Significant transit traffic uses Panama as a connecting hub.
Cubana de Aviación — fleet constraints driven by sanctions on parts and lessor relationships have reduced international network in recent years.
Historical Context (Factual)
The MUFH FIR sits across one of the busiest oceanic intersections in the Western hemisphere. ICAO route structure assigns Cuba a strategic role in Caribbean and Florida–Central America traffic. US–Cuba aviation relations have followed a long political cycle: the 1962 embargo halted scheduled service; charter operations resumed under successive licences from the 1970s; scheduled service was restored under a 2016 bilateral agreement; policy was tightened in 2017–2019 and again in 2024–2025.
The Caribbean weather environment is the second persistent factor. Atlantic hurricane tracks frequently cross the western and central Cuban coast, with periodic closures of MUHA, MUVR, and provincial fields during the June–November season.
Operating Airports & Carriers
José Martí International (Havana) — primary international gateway and Cubana hub.
Varadero — leisure gateway; heavy Canadian and European charter traffic.
Holguín — eastern Cuba; seasonal European and Canadian service.
Cayo Coco — leisure gateway in the north-central archipelago.
Santa Clara — Abel Santamaría International; charter and limited scheduled service.
