Disrupted Skies: The New Normal in GlobalAviation Operations

Season 1, Episode 13 | October 8 th, 2025

Executive Summary

In this episode of Altitude, hosts Fabricio Cojuc, Nicolás Rhoads, and Arturo Duhart analyze the growing phenomenon of mass operational disruptions across global aviation — from cyberattacks and weather chaos to drone incursions, airspace violations, and largescale aircraft groundings.

Key highlights include:

• Mexico City Airport (AICM): recurring closures due to protests, storms, and lightning, affecting tens of thousands of passengers and exposing long-standing infrastructure vulnerabilities.

• Europe: a string of severe disruptions — from a ransomware attack paralysing Berlin, Brussels, and Heathrow (1,420 flights canceled, 210,000 passengers affected) to drone incursions in Munich and Copenhagen and even balloon intrusions in Vilnius linked to smuggling.

• Cyber and communication failures: including an incident involving EU Commission President Ursula von der Leyen’s aircraft, highlighting the fragility of flightmanagement systems even at state level.

• Pratt & Whitney PW1000-series engine crisis: grounding approximately 650 Airbus A320neo aircraft worldwide (≈30% of the fleet), disrupting operations for years. Airlines like Volaris (Mexico) and Wizz Air (Europe) have seen up to 20–30% of their fleets grounded, causing lost market share, route cuts, and soaring lease and maintenance costs.

The hosts conclude that aviation is entering an age of permanent disruption, requiring governments, airlines, and airports to strengthen technological resilience, emergency coordination, fleet diversification, and disaster-recovery planning. Passengers, too, must adapt — adopting a mindset of flexibility, broader connection times, and travel-disruption insurance.

Fabricio: Welcome to Altitude. Fasten your seat belts — we’re ready for take-off. Let’s talk aviation seriously.

A growing phenomenon catching our attention is the surge in massive disruptions affecting airlines and airports worldwide: system outages, cyberattacks, airport closures due to protests, weather, or unauthorized drone and balloon activity, and the large-scale grounding of aircraft due to engine issues. These events are no longer occasional; they’ve become structural.

Nicolas: Exactly. Great to be back. Let’s get started.

Arturo: Let’s begin with Mexico. On May 23, operations at Mexico City International Airport (AICM) were halted for about 18 minutes due to a teachers’ protest blocking the access roads — not weather-related, yet causing delays to some 12 flights (mainly Monterrey, Cancún, Guadalajara).

Then, on June 12, heavy rains flooded the runways: 70 flights delayed, 9 canceled, about 6,000 passengers affected. The most severe event came August 11–12, when unprecedented overnight rainfall closed the airport for nearly four hours — 87 flights delayed, 22 canceled, and 19,000 passengers impacted, with long-haul flights diverted to Toluca, Querétaro, and Santa Lucía.

Later, on September 14 and 28, lightning strikes forced intermittent runway closures again, delaying over 100 flights, canceling 15, and disrupting mainly night-time connections to the U.S. and Central America.

Fabricio: Indeed — these recurring incidents highlight both the system’s vulnerability and the urgent need to modernize airport infrastructure. With major global events coming next year, a disruption of that scale could severely damage Mexico’s image internationally.

Arturo: Exactly. Now, let’s move to Europe. A few weeks ago, there was a communication-system incident on September 18 involving European Commission President Ursula von der Leyen. Her German Air Force Airbus A321 had to make an emergency landing in Reykjavik after the flight-management and communication systems desynchronized. It delayed her schedule two hours — showing that even state aircraft are not immune to digital failures.

Authorities didn’t classify it as a deliberate attack, but the event shows how fragile flightcontrol systems can be.

Fabricio: And just one day later, on September 19, a ransomware attack caused a full operational collapse at Berlin, Brussels, and London Heathrow airports.

Nicolás: Exactly — 1,420 flights canceled, 210,000 passengers affected. Airlines like Lufthansa, British Airways, Brussels Airlines, and Ryanair were hardest hit. I flew from Berlin to Amsterdam ten days later, and the check-in system was still down — everything was being done manually. Staff printed passenger lists and verified identities with laptops and passports, just like 30 years ago.

They even made constant announcements warning travelers about IT disruptions, urging them to re-check their itineraries. This shows how digital dependence and lack of contingency systems are now major operational risks.

Fabricio: Indeed. Even top global hubs like Heathrow are improvising rather than executing structured contingency plans.

Arturo: And the issue didn’t stop there. On September 22, Munich Airport suspended operations for nearly three hours due to confirmed drone sightings, canceling 112 flights, delaying 178, and affecting 23,000 passengers. Ten days later, on October 3, another drone incursion forced more cancellations and diversions.

Then, in Vilnius (Lithuania), up to 25 unauthorized balloons — reportedly used for cigarette smuggling — entered controlled airspace, closing the airport for hours and affecting 30 flights and 6,000 passengers.

The same day, Copenhagen Airport was closed for four hours after multiple drone sightings, with 50 flights diverted.

Fabricio: While weather disruptions can be forecast and managed, these unpredictable events — drones, cyberattacks, digital failures — collapse operations in seconds, catching both operators and passengers unprepared.

Arturo: Exactly. And the question is: what can be done? Because these events could easily escalate into systemic crises.

Fabricio: Speaking of systemic impact, another major disruption has come from the grounding of A320neo aircraft powered by Pratt & Whitney PW1000-series (GTF) engines. Around 650 aircraft worldwide — nearly 30% of that fleet — are out of service, with inspections and repairs averaging 10 months per unit due to supply-chain bottlenecks.

Airlines have had to reconfigure schedules, cut routes, postpone growth, and absorb heavy financial and reputational damage. Compensation from the manufacturer doesn’t offset lost competitiveness or customer dissatisfaction.

Exactly. For example, Volaris has kept about 30 aircraft grounded since 2024, a situation expected to last until 2027. This led to a 3% drop in Mexico’s domestic market in 2024 and cost Volaris its market-share leadership to Viva Aerobus.

Similarly, Wizz Air in Europe has around 20% of its fleet grounded (≈40 aircraft), with disruptions extending into 2026. These crises show how fragile the global aviation ecosystem remains.

Arturo: So yes, aviation faces a new reality of permanent disruption.

Governments must reinforce emergency protocols and improve crisis communication with airlines. Airlines must diversify fleets, strengthen technological resilience, and build agile Disaster-Recovery Plans. Airports need modern backup systems that don’t force operations back to the 1990s.

Fabricio: And passengers must adapt too — with more flexible travel plans, travel-disruption insurance, and longer connection windows. Personally, I’ve started allowing much more buffer time between flights because disruptions have become the new normal.

Arturo: Exactly. These events are no longer exceptional — they’ve become part of modern aviation’s landscape.

Fabricio: A fascinating and urgent topic. Let’s hope the industry evolves toward greater preparedness and resilience.
