Etna eruption diverts 10‑hour delayed Budapest flight to Palermo

A fresh eruption of Mount Etna has thrown air travel across southern Italy into disarray, with a Ryanair service from Budapest enduring around 10 hours of delays before being rerouted from Catania to Palermo.

Volcanic ash grounds traffic in eastern Sicily

The latest eruptive phase at Mount Etna intensified between Sunday 5 July and Monday 6 July, sending towering ash columns into the skies above eastern Sicily and prompting aviation alerts for the surrounding airspace. The renewed activity has led to widespread disruption at Catania Fontanarossa Airport, a major gateway for summer tourism on the island.

Local reports indicate that operations at Catania have been severely curtailed as ash drifted across flight paths, affecting visibility and raising concerns over engine safety. Volcanic ash can damage aircraft turbines, making even short‑haul operations vulnerable when plumes move over approach and departure corridors.

The disruption has come at the height of the Mediterranean holiday season, with airlines and airports across the region already operating close to capacity. The intersection of peak demand and sudden airspace restrictions has quickly translated into significant delays, diversions and cancellations for passengers heading to and from Sicily.

Travel industry coverage notes that aviation authorities routinely impose temporary closures or capacity limits around Etna during periods of heightened ash emission, with the extent of disruption depending on wind patterns and the persistence of the eruption.

Ryanair Budapest service hit by 10‑hour delay

Among the flights affected was a Ryanair service scheduled to operate between Budapest and Catania. According to Hungarian travel reporting and flight‑tracking data, the departure from Budapest Ferenc Liszt International Airport was pushed back by roughly 10 hours as the situation in Sicilian airspace evolved.

Passengers following updates from Budapest Airport and independent aviation pages on social media saw the scheduled Ryanair flight remain on the ground for much of the day while operators assessed whether Catania could safely accept arrivals. The prolonged delay reflected both the uncertainty around ash movements and the knock‑on effect on wider regional traffic.

Publicly available flight information shows that Ryanair has been running multiple summer services linking Budapest with Sicily, reflecting strong demand from Central European travelers for direct access to Mediterranean destinations. The Etna eruption has abruptly complicated these routings, forcing the airline to weigh delays against alternative airports for diversions.

Reports indicate that, as the delay stretched into the evening, options narrowed for keeping to the original schedule without breaching crew duty limits and slot constraints at busy Italian airports.

Switch of destination from Catania to Palermo

As restrictions around Catania persisted, updates from Budapest Airport later in the evening showed the affected Ryanair flight changing its planned destination from Catania to Palermo. Travel coverage from Hungary described the service as now heading to Palermo Falcone Borsellino Airport instead of its original arrival point on Sicily’s east coast.

The diversion reflects a wider pattern seen across the island, with Palermo emerging as a key relief hub whenever Etna’s activity disrupts operations at Catania. Information published by Palermo Airport and regional media on Sunday 5 July reported more than 20 additional flights being handled in a single day after being diverted from Catania due to the volcanic emergency.

Despite the extra traffic, Palermo’s operator reported maintaining regular operations with over one hundred scheduled arrivals and departures alongside the diverted services. Ground teams have been coordinating onward transfers by road to Catania for passengers whose journeys end on Sicily’s eastern side.

For travelers on the Budapest flight, the late decision to reroute to Palermo means arrival on the opposite coast of the island, adding several hours of onward surface travel to an already long day of disruption.

Knock‑on effects for passengers and summer schedules

The Etna eruption has underlined how quickly conditions can change for airlines operating tightly timed summer schedules. A lengthy delay at the start of the day can ripple through subsequent rotations, particularly for low‑cost carriers whose aircraft typically operate multiple sectors.

Travel forums and social media posts from passengers across Europe on Monday describe uncertainty around departure times and diversions involving Catania, Palermo, Trapani and Comiso, as airlines adjust routings around the ash cloud. Some services bound for eastern Sicily have been held at their point of origin, while others have been redirected mid‑route to alternative airports.

Public information from airports in Sicily suggests that, while Catania remains the focal point of disruption, facilities on the western side of the island are absorbing additional traffic relatively smoothly. However, the rerouting places extra strain on ground transport networks as buses and coaches are mobilised at short notice to carry passengers across the island.

Travel specialists note that, during volcanic events in Sicily, conditions can either stabilise within hours or continue intermittently for days, making it difficult for airlines to give precise forecasts for affected services. Passengers are being encouraged, through airline and airport updates, to check flight status frequently and to allow extra time for connections.

What travelers to Sicily should expect next

With Etna’s activity still being monitored as of Monday 6 July, the outlook for air travel to and from eastern Sicily remains fluid. European meteorological and volcanic ash advisory centers continue to evaluate plume height, concentration and drift, which in turn inform decisions on reopening or restricting specific airspace corridors.

For holidaymakers booked on flights to Catania in the coming days, published guidance from airlines and travel agents stresses the importance of remaining flexible about potential schedule changes or alternative arrival airports such as Palermo or Comiso. In some cases, carriers may consolidate services or move passengers onto later flights once operational certainty improves.

Travel insurers typically treat volcanic ash disruption as an extraordinary circumstance, but policies can differ on what costs may be reimbursed. Passengers are advised in consumer travel columns to review their coverage details, particularly in relation to accommodation and missed connections, before setting off.

While Sicily itself remains open to visitors and most of the island’s infrastructure is operating normally, the current episode around Etna is a reminder that dynamic natural hazards continue to shape travel plans in the central Mediterranean, sometimes turning a routine two‑hour hop into a long, uncertain journey via an unexpected destination.
