Wizz Air’s rapid expansion across Europe and the Middle East has created an extensive network of routes served by Airbus A320‑family aircraft. Between January 2022 and December 2025 the airline and its subsidiaries faced a series of emergencies ranging from minor cabin fires to engine failures and bomb threats. These events reveal how flight crews applied standard procedures to handle crises while still bringing passengers to safety. The following chronology summarises every documented emergency landing or serious incident affecting Wizz Air and officially acknowledged by investigative authorities or by the airline during the period.

Early incidents in 2022

Thermal‑runaway fire near Bergen (June 11 2022)

In June 2022 a Wizz Air flight from Szczecin, Poland, to Bergen, Norway, encountered an unusual emergency. During the top‑of‑descent the cabin crew noticed smoke emanating from a passenger’s mobile phone, which had overheated and erupted into a lithium‑ion battery fire. The crew followed the operator’s battery‑fire procedure: they donned gloves and breathing equipment, applied water and a halon fire extinguisher to cool the phone, and placed it inside a metal container with water. The flight deck declared a MAYDAY to air traffic control and continued the descent. One passenger sustained minor burns while moving the device, but the crew contained the fire and there were no further injuries. The Norwegian Safety Investigation Authority later praised the crew’s swift response and noted that the incident resulted only in a burnt cabin carpet[1].

Hard landing and tail strike at Kutaisi (May 26 2022)

A few weeks earlier, an Airbus A321 (registration HA‑LVR) operating into Kutaisi Airport in Georgia experienced a hard landing that resulted in a tail strike. The aircraft touched down nose‑high, causing the rear fuselage to contact the runway. The flight landed safely and taxied to the stand, but inspections revealed damage to the tail cone. The occurrence was classified as a serious incident, and investigators from the Hungarian Transportation Safety Bureau took responsibility for the case[2]. It underscored the need for adherence to stabilized‑approach criteria when operating into challenging regional airports.

Bomb threat and emergency evacuation (July 20 2022)

In July 2022 Wizz Air confronted a more dramatic emergency. An Airbus A321 neo flying from Bari, Italy, to Kraków, Poland, received a bomb threat while en route. The crew diverted to Budapest Ferenc Liszt International Airport and landed without incident. As the aircraft stopped on a remote stand the ground team was unprepared to deploy stairs, prompting the flight crew to order a rapid evacuation. All eight emergency slides were deployed and passengers exited the aircraft; several sustained minor injuries from the abrupt slide descent. The event was treated as an accident with serious injuries by investigators[3][4] and emphasized the importance of ground coordination during bomb‑threat diversions.

Safety issues in 2023

Tail‑strike during go‑around at Abu Dhabi (April 29 2023)

Wizz Air Abu Dhabi’s A321‑271NX (registration A6‑WZG) experienced a tail strike after a bounced landing at Abu Dhabi International Airport. Gusty winds caused the main landing gear to remain on the runway while the nose gear floated. Believing there was sufficient energy, the copilot initiated a go‑around with a high nose‑up input while the airspeed was still low. The aircraft’s tail scraped along the runway for about three seconds before lifting off[5]. Investigators concluded that the improper pitch‑control technique and inadequate crew communication were the primary causes. Safety recommendations included enhanced simulator training on low‑energy go‑arounds and greater emphasis on crew resource management.

Unruly passenger diversion to Belgrade (September 6 2023)

A routine flight from Tel Aviv to London Luton was diverted to Belgrade after a passenger became violent. According to the airline, the individual assaulted cabin crew and attempted to open a door mid‑flight. The captain declared an emergency and landed at Belgrade’s Nikola Tesla Airport, where police removed the passenger. Wizz Air confirmed the diversion and apologised for the disruption[6]. While not investigated by a government agency, the event represented an officially acknowledged emergency landing due to security concerns and highlighted the importance of crew training for handling unruly passengers.

Engine and pressurization issues in 2024–25

Engine vibration and return to Kraków (July 24 2024)

In July 2024 an Airbus A321‑271NX (registration 9H‑WBU) operating as flight W62043 departed Kraków bound for an undisclosed destination. Shortly after take‑off, while climbing through about 6,000 ft, the crew detected severe vibrations from one engine. They shut the engine down, declared PAN PAN and returned to the departure airport. The landing was uneventful, and maintenance teams later inspected the engine. Poland’s State Commission on Aircraft Accident Investigation (PKBWL) classified the occurrence as a serious incident and credited the crew’s rapid decision‑making[7].

Cabin‑pressure emergency descent (February 4 2025)

Early in 2025, a Wizz Air Malta Airbus A321 (registration HA‑LTK) cruising at flight‑level 330 over Bulgaria experienced a high cabin‑altitude warning. The crew began a normal descent to address the problem, but when the cabin altitude exceeded 14,000 ft they declared MAYDAY. Flight and cabin crews donned oxygen masks and deployed passenger oxygen units as a precaution[8]. The aircraft descended to 10,000 ft, the warning cleared, and the mayday was cancelled. The flight continued to its destination at Bucharest Henri Coandă International Airport and landed without further incident. The preliminary investigation attributed the event to a pressurization‑control issue; no injuries were reported.

Engine‑oil leak and diversion to Geneva (May 26 2025)

A few months later Wizz Air Malta flight W61613, operated by A321‑271NX (9H‑WAD), was cruising at 35,000 ft over southwestern Germany when the crew noticed that the left engine’s oil quantity and pressure were falling rapidly. Following procedures, they shut the engine down, declared PAN PAN and diverted to Geneva. The single‑engine landing was completed safely after approximately forty minutes[9]. Investigators from Switzerland’s Transportation Safety Investigation Board later determined that an incorrectly installed air‑to‑oil heat exchanger had caused the leak. The event demonstrated how redundancy in modern aircraft systems allows safe flight after engine shutdown.

Smoke odour and avionics faults (July 20 2025)

On 20 July 2025, an Airbus A321 (registration G‑WUKP) operated by Wizz Air UK on a flight from Poznań, Poland, to London Luton detected a smoke smell in the cockpit while cruising at FL360. Shortly thereafter the autopilot and autothrottle disengaged. The crew declared MAYDAY, donned oxygen masks and diverted to Amsterdam Schiphol Airport. The aircraft landed safely on runway 22; there were no injuries. Preliminary data from the Dutch Safety Board indicated that the incident was classified as a serious incident[10], and a detailed investigation was launched to determine the source of the smoke and avionics anomalies.

Tail‑strike in Prague (September 11 2025)

Later that year, Wizz Air UK’s first Airbus A321XLR (registration G‑XLRA) experienced a hard landing at Prague’s Václav Havel Airport. The aircraft bounced upon touchdown, and the tail struck the runway before the crew recovered and brought the aircraft to a stop. No injuries were reported, but the event was recorded as a serious incident[11]. Czech accident investigators assumed responsibility for the case. This incident, combined with the earlier tail‑strike in Abu Dhabi, underscored the sensitivity of the elongated A321 variants to pitch control during landing.

Pattern of safety and response

Across the ten emergencies described above, a clear pattern emerges. Wizz Air flight crews consistently followed established safety procedures—whether extinguishing a battery fire, managing engine failures, or dealing with pressurization anomalies. They declared emergencies or PAN PAN when required, coordinated with air traffic control, and made decisions to return or divert. Importantly, none of these events resulted in fatalities. Injuries were limited to minor burns during the 2022 battery fire and minor slide injuries during the bomb‑threat evacuation. Investigative agencies—including the Norwegian Safety Investigation Authority, Hungary’s TSB, the Air Accident Investigation Sector of the United Arab Emirates, Poland’s PKBWL, Switzerland’s STSB, Bulgaria’s authority, and the Dutch and Czech safety boards—opened investigations, issued recommendations and highlighted training, maintenance and coordination issues.

These emergencies also show that low‑cost carriers like Wizz Air face the same operational risks as larger airlines and must maintain robust safety management systems. The airline’s willingness to issue public statements following incidents (such as the 2023 Belgrade diversion) indicates an awareness of transparency. By the end of 2025 Wizz Air had incorporated lessons from these events into training and procedures, helping ensure that future emergencies will be handled with similar professionalism.
