Tigerair Taiwan Fined Over Rs 4 Lakh After Passenger Boards Wrong Osaka Flight

Taiwan's Civil Aviation Administration (CAA) has fined Tigerair Taiwan NT$150,000 (approximately ₹4,54,893) after a passenger mistakenly boarded the wrong flight, as per reports. The incident took place in December 2025 at Kaohsiung International Airport, where a traveller scheduled to fly to Tokyo's Narita Airport boarded a flight bound for Osaka instead. The case surfaced after an investigation was completed, with authorities citing a lapse in boarding checks that led to the regulatory action.

Passenger Boarded Osaka Flight Instead Of Tokyo

The mix-up involved a passenger booked on Tigerair flight IT280 from Kaohsiung to Tokyo Narita, who instead boarded flight IT284 heading to Osaka. According to Taipei Times, the error went unnoticed during the initial boarding checks at the departure gate. It was only identified shortly after boarding, before takeoff, allowing airline staff to escort the passenger off the Osaka-bound aircraft. Tigerair later reported the incident to the Civil Aviation Administration.

Why The Airline Was Penalised

In its statement, as per Aviation A to Z, the CAA said airline personnel “failed to properly verify passenger identity and boarding eligibility,” a requirement mandated under Taiwan's aviation security framework. The CAA said the lapse occurred because gate staff failed to properly verify the passenger's identity, allowing them to board the incorrect aircraft. This was deemed a violation of Taiwan's civil aviation security regulations, leading to a fine under the Civil Aviation Act.

The regulator said such incidents highlight the importance of strict identity checks during boarding procedures.

Airline Response

Following the penalty, the CAA has asked Tigerair Taiwan to review its procedures and submit a report outlining steps taken to prevent similar incidents in the future.

The airline said it accepts the regulator's decision and has already implemented improvements, reiterating that passenger safety remains its top priority, as reported by Taipei Times and Taiwan News.

Separate Incident Also Flagged

In a separate case, the CAA noted that a Tigerair Taiwan flight from Taoyuan to Sapporo in August last year failed to follow air traffic control instructions, resulting in an altitude deviation mid-flight. Authorities said the airline has been asked to strengthen internal discipline, training, and crew management practices following that incident as well.

Regulators urged that even minor gaps in ground procedures can pose significant risks, especially in high-traffic airport environments where multiple flights are boarding simultaneously.
