The return of Houthi attacks to the Red Sea has widened a Middle East transport crisis that was already testing airlines, shipping companies and travel businesses across the Gulf. Commercial traffic through the Bab el-Mandeb Strait fell sharply on 26 July after the Houthis targeted Saudi oil infrastructure and threatened vessels serving the kingdom. Only 11 commodity ships crossed the waterway that day, the lowest number recorded in several months. Traffic through the Strait of Hormuz also remained subdued, despite a pause in direct fighting between the United States and Iran.

For the travel industry, this is no longer solely a maritime or energy-market story. The instability now stretches across two of the region’s most important transport corridors, close to major aviation routes, cruise deployment areas and tourism investments in Saudi Arabia and the Gulf.

The leading Gulf airports remain open. Hotels, attractions and tourism services in destinations such as Dubai, Abu Dhabi and Doha continue to operate. The pressure is being felt less through destination closures than through the transport system that feeds them: airspace warnings, longer flight paths, volatile fuel costs, disrupted cruise planning and a growing insurance burden.

Two chokepoints, one wider operating risk

The Houthis’ renewed campaign has altered the geographical reach of the conflict. The group had already disrupted Red Sea shipping after the start of the Gaza war, forcing many operators to abandon the Suez Canal and sail around southern Africa. Those diversions added days to voyages and drove up fuel, crew and insurance costs.

The latest threat is broader. The Houthis have declared what they describe as a blockade of Saudi-linked shipping, while attacks and interceptions around Hormuz have depressed vessel movements through the Gulf. Five tankers changed direction in the Red Sea shortly after the warning was issued. The response showed how quickly operators are prepared to alter course when threat levels rise, even before a waterway is formally closed.

Maritime instability can affect cruise itineraries and port calls directly, but it also feeds into oil prices, aviation fuel bills and consumer sentiment. When two strategic waterways are under pressure at the same time, disruption is harder to contain. Brent crude rose above US$100 after the Houthi attacks on Saudi tankers, before falling back as Washington and Tehran paused military action. The retreat offered some relief, but it did little to remove the risk premium facing airlines during the summer peak.

Fuel is only one part of the equation. Carriers must also account for longer sectors, additional crew hours, aircraft rotation problems and the possibility of airspace restrictions being imposed or withdrawn at short notice.

Airlines face a shifting airspace map

Middle East aviation has spent several years adapting to closed or restricted corridors over Syria, Iraq, Iran, Israel and parts of the Arabian Peninsula. What has changed is the scale and speed of the latest disruption. The European Union Aviation Safety Agency allowed an earlier region-wide Middle East bulletin to expire on 8 July after a reduction in tensions. Within days, however, it issued a fresh advisory covering the Persian Gulf and Gulf of Oman. Separate warnings for Iraqi and Lebanese airspace remain active, according to EASA’s conflict-zone advisory register.

For airline network planners, that creates a moving operational boundary rather than a fixed no-fly zone. Routes that are available one day may become commercially or operationally unattractive the next, even when regulators have not ordered a complete suspension. Gulf carriers are better placed than many competitors to manage that uncertainty. They have large networks, substantial operational control at their home hubs and years of experience rerouting aircraft around regional conflicts. Their schedules, however, do not exist in isolation.

European and Asian airlines may take more conservative positions, reducing frequencies or suspending services when their own security assessments change. That can weaken feeder traffic into Gulf hubs and complicate itineraries built across separate carriers. For travel management companies, short connections now carry greater risk. A journey that works on paper may unravel if an inbound aircraft takes a longer route, departs late or is held while airspace is reassessed.

The disruption is particularly significant for flights between South Asia, the Gulf and Europe. These services rely on narrow route corridors and tightly managed aircraft rotations. A diversion of even 30 or 40 minutes can have consequences across the rest of an airline’s schedule.

Cruise recovery faces another setback

Cruise companies began removing Red Sea and Suez Canal itineraries after Houthi attacks intensified in late 2023. Repositioning voyages between Europe, the Gulf and Asia were cancelled or redirected around the Cape of Good Hope, often making the original itinerary unworkable. A stable passage through Bab el-Mandeb is essential if those deployments are to return at scale.

The latest attacks will make cruise operators cautious about restoring Red Sea programmes, even where individual ports remain open. Cruise planning is conducted months, sometimes years, in advance. Operators require confidence not only in the safety of a destination but also in the viability of the entire route.

Saudi Arabia has invested heavily in Red Sea tourism, including cruise infrastructure, coastal resorts and large destination developments. The affected security zones are not necessarily close to the kingdom’s principal leisure projects, but geography rarely determines traveller perception on its own.

An attack on a Saudi port or tanker can quickly become a wider “Red Sea” story in international markets. Tour operators then face questions about destinations hundreds of kilometres away from the incident. The commercial task is to distinguish between disruption to a transport corridor and conditions within a destination. Selling either as entirely unaffected or entirely unsafe would misrepresent the situation.

War-risk insurance costs return to the balance sheet

Insurance is becoming one of the clearest measures of the conflict’s business impact. War-risk premiums for voyages through the southern Red Sea surged after the latest Houthi attacks. The increase raises costs for shipping operators and could influence cruise deployment decisions if underwriters judge the threat to be sustained.

Travel insurance presents a different problem. Many policies exclude losses connected to war, military action or travel undertaken against official government advice. Customers who cancel because they feel uneasy may discover that apprehension alone is not an insured event. That distinction should be addressed at the point of sale, not after disruption occurs.

Agents and corporate travel managers need to know whether a booking is protected if an airline cancels, reroutes or delays a service. They should also establish who carries the financial responsibility when flights, hotels and ground arrangements have been booked separately. Self-connected itineraries are especially exposed. An airline may refund a cancelled sector without accepting liability for a separately booked onward flight or hotel stay.

Official advice is equally important. The UK Foreign, Commonwealth & Development Office continues to warn against travel to parts of Saudi Arabia near the Yemeni border. Its Saudi Arabia travel advisory does not amount to a warning against visiting the country as a whole, but it gives travel companies a geographical framework for assessing risk and insurance validity.

Gulf hubs remain open, but resilience comes at a price

The Middle East’s main aviation hubs are not facing a repeat of the widespread shutdowns seen during the pandemic. Flights continue, passengers are connecting and the region’s tourism economies remain active. Yet normal operations should not be confused with normal costs.

Airlines are paying more to preserve schedules. Shipping companies are avoiding shorter routes. Cruise operators are delaying deployment decisions. Travel sellers are spending more time managing waivers, checking advisories and rebuilding itineraries. Those costs will eventually appear somewhere — in fares, insurance premiums, reduced capacity or tighter booking conditions.

The Gulf’s aviation model remains remarkably resilient. Dubai, Doha and Abu Dhabi have built their position by connecting markets that often lack strong direct links. That advantage becomes even more valuable when global networks are fragmented. It also leaves the hubs exposed to instability on several sides. Their airlines must navigate political and military risks across the Gulf, the Levant, the Red Sea and South Asia while protecting the punctual connections on which their business model depends.

The immediate test will be whether the pause between Washington and Tehran develops into a durable diplomatic opening. A reduction in direct hostilities could ease pressure around Hormuz and pull oil prices lower. It would not automatically end the Houthi campaign in the Red Sea, nor would it persuade shipping and cruise companies to return immediately.

Operators will want to see sustained vessel movements, lower insurance premiums and a period without attacks before treating either route as stable. For airlines and travel businesses, the coming weeks will be defined by operational vigilance rather than wholesale withdrawal. Capacity is likely to remain in the market, especially at the Gulf’s major hubs, but schedules will need more room for disruption.

The Middle East remains open for travel. Getting passengers there — reliably, affordably and with adequate protection — is becoming the harder part.
