Austrian Airlines flight OS82, carrying 51 passengers and six crew, was diverted to Sofia, Bulgaria, on Sunday, October 18, 2026, after receiving a bomb threat near the Romanian border. This incident forced an unscheduled landing and triggered security protocols including a fighter jet escort.

Bomb threats against commercial airliners disrupt travel, cause significant fear for passengers and crew, and strain international security resources, highlighting ongoing vulnerabilities in aviation safety. Such events necessitate rapid responses from multiple national authorities, impacting air travel safety and operational efficiency.

What the records show

Bulgaria's Ministry of Transport and Communications indicated that the crew of flight OS82 reported a bomb threat signal as the aircraft approached the Romanian border. The captain transmitted the international emergency transponder code, Squawk 7700, signaling a general emergency. As a result, the Bulgarian Air Force scrambled MiG-29 fighter jets to escort the Airbus A320 to Sofia, a measure described as part of established procedures. The Lufthansa Group, which includes Austrian Airlines, confirmed the threat against the flight.

The Timeline

Austrian Airlines flight OS82 departed from Tel Aviv, Israel, on Sunday evening, October 18, 2026, en route to Vienna, Austria. The crew reportedly received the bomb threat near the Romanian border shortly into the flight. The Airbus A320 then diverted course and touched down safely at Sofia Airport at approximately 8:42 p.m. Central European Summer Time. One report indicated a landing at approximately 7:42 p.m. local time in Sofia.

What changed and for whom

All 51 passengers and six crew members disembarked safely at Sofia Airport. Following their safe exit, security checks were launched on the aircraft. Passengers were informed of an anonymous report of a bomb aboard the aircraft. The Lufthansa Group stated that passengers would be rebooked on an alternative flight as soon as possible after the aircraft search was complete. This incident follows a hoax bomb threat in July 2026, which involved a Qatar Airways 777 being escorted by RAF Typhoon jets.

What the subject has said publicly

An Austrian Airlines spokeswoman confirmed the event to the Vienna daily Der Standard, stating, "We confirm that there was a threat against flight OS82 from Tel Aviv to Vienna, which made an intermediate landing in Sofia necessary". The Lufthansa Group reiterated this, stating, "We confirm that a threat was received concerning Austrian Airlines flight OS82 from Tel Aviv to Vienna, prompting the aircraft to divert to Sofia, Bulgaria". The Israel Air Force noted that the incident did not occur in or near Israeli airspace, indicating they were not involved and not required to act.
