Gulf Conflict, Krakatau Eruption and Record El Niño Compound Risks for Charter Aviation Through Early 2027

The operating environment for private and charter aviation has reached its worst point since a Middle East conflict began on February 28, with an unresolved conflict involving the United States, Israel and Iran now compounded by a strengthening El Niño causing volcanic, hydrological and air-quality disruption across Asia. Iran has launched what is described as its largest missile barrage since the end of operations, with missiles intercepted over Jordan, while US forces have struck Iranian tankers, pushing oil prices to their highest level since July. The Islamic Revolutionary Guard Corps navy claims to have seized an unmanned US submersible in the Strait of Hormuz, and the Bab al-Mandeb strait has re-emerged as a contested chokepoint. Kuwait International Airport has been closed for five weeks following drone strikes that destroyed radar and fuel systems, with no reopening date announced.

Scheduled capacity suspensions are extensive: Lufthansa Group has suspended multiple routes including Dubai and Beirut through October 24; British Airways has suspended Dubai, Tel Aviv, Bahrain and Amman through October 25; Singapore Airlines and Wizz Air have suspended Dubai — and in Wizz Air's case Abu Dhabi — through October 24; Cathay Pacific has suspended Dubai and Riyadh through November 30; Air Canada has suspended Tel Aviv and Dubai through January 2027; Delta has suspended its Atlanta–Tel Aviv service through December 18; and the Incheon–Dubai route is suspended until further notice. The United States has sanctioned 27 further Iranian airlines under Operation Economic Outcast, including withdrawal of authorisations that had permitted overflights and allowed non-US airlines to operate US-origin or US-controlled aircraft into Iran.

In Asia-Pacific, the eruption of Mount Anak Krakatau has forced suspension of flight operations at several Indonesian airports and disrupted corridors across Java and Sumatra, with Bali's I Gusti Ngurah Rai International Airport showing cancellations due to volcanic activity on September 7. Transboundary haze from Indonesian fires has driven particulate levels in Banjarbaru, South Kalimantan, to 389.4 micrograms per cubic metre against a national danger threshold of 250.5, and has closed more than 100 schools in Malaysia's Sarawak state. Typhoon Saudel brought severe flooding to Fujian and Guangdong. The World Meteorological Organization stated on September 3 that El Niño is firmly established and expected to become a very strong event peaking towards the end of 2026, with a near-certain probability of persisting through February 2027; one government minister characterised it as potentially the largest in at least 1,000 years. Above-normal temperatures are forecast across almost all land areas from September to November, with subdued monsoon rainfall in South Asia — India ended August with a 16 percent deficit — and drier conditions in Indonesia and Australia.

This is a case of two normally separate risk categories — armed conflict and seasonal climate variability — landing on overlapping regions at the same time, so operators cannot treat either one as an isolated, containable event. Charter and fractional planning ordinarily absorbs a single disruption by rerouting around a closed airport or a storm system; here the Gulf conflict removes scheduled and on-demand capacity across multiple hub airports simultaneously while the El Niño-driven volcanic and haze conditions remove alternate routing options across a second region entirely.

For brokers working with US-manufactured or US-controlled aircraft, the sanctions against 27 Iranian airlines under Operation Economic Outcast turn a routing decision into a compliance one: withdrawn overflight authorisations affect which aircraft can legally be placed on Iran-adjacent routings regardless of whether the physical airspace is open. That distinction between a closed corridor and a prohibited one is not interchangeable, and treating them the same risks a sanctions violation rather than a mere delay.

The airline suspension expiry dates clustered around October 24 and 25 are the near-term signal for whether Gulf capacity is genuinely returning or being extended again, and Air Canada's suspension running through January 2027 already suggests some carriers expect the disruption to outlast the northern autumn. With the World Meteorological Organization projecting El Niño conditions persisting through February 2027, the current combination of constraints functions as the fourth-quarter planning baseline rather than a temporary exception to be waited out.
