DELHI- A business class passenger on Singapore Airlines (SQ) flight SQ406 reported a privacy breach involving a malfunctioning lavatory door before departure at Singapore Changi Airport (SIN) on December 2, 2025. The aircraft was scheduled to fly to Delhi Indira Gandhi International Airport (DEL).
The airline confirmed that the lavatory was locked for the rest of the flight after the fault was reported. The passenger later shared concerns about how the incident and follow-up response were handled.

Singapore Airlines A380 Lavatory Malfunction
The incident occurred while the aircraft was still on the ground. The passenger said the rear lavatory door opened twice despite being locked, which resulted in a significant loss of privacy.
The individual described the experience as humiliating and noted that it raised concerns about equipment maintenance and service recovery.
According to the airline, the cabin crew were informed about the fault, apologised at the time, locked the lavatory, and marked it unserviceable.
The lavatory remained unavailable for the entire journey to prevent further disruptions. The door was repaired and inspected after arrival in Delhi.
The passenger said the malfunction caused the casement door to open fully, leaving them exposed until they managed to cover themselves and attempt to close it. They stated that the failure of the lock created a severe breach of privacy and left them distressed.
They added that the in-flight supervisor acknowledged the fault, but no additional action was taken to address the discomfort caused. The passenger later contacted the airline and received an apology, which they felt lacked sincerity, reported Stomp.

The airline also confirmed that it has been in direct contact with the passenger to provide support following their complaint.
The carrier acknowledged the distress caused and stated that steps were taken to prevent further access to the faulty facility during the flight.

Equipment Maintenance and Customer Care
Lavatory hardware faults can cause operational and customer service challenges, especially during boarding. This incident highlights the importance of pre-flight checks and timely repairs to prevent similar issues.
The airline stated that corrective work was completed and additional verification carried out to confirm the lavatory’s condition before future services.

Similar Incident
A passenger flying with IndiGo (6E) from Mumbai Airport (BOM) reported a serious privacy breach involving a First Officer who allegedly opened an occupied lavatory before departure.
The woman, identified as Rhea Chatterji, stated that the airline minimized her experience despite multiple attempts to report the incident to crew members and senior leadership.
Safety and Dignity Concerns
The incident took place on August 8, 2025, on a late-night IndiGo (6E) service departing from Mumbai Airport (BOM).
According to Chatterji, she boarded the aircraft and used the forward lavatory before pushback. She said she confirmed the lock was secured. After responding to two knocks, the door was opened by a male crew member believed to be the First Officer. She said he immediately closed the door after seeing her in a vulnerable state.
Chatterji described feeling shocked and unsafe inside the confined cabin environment. She later wrote that female flight attendants apologized for what they called an inconvenience. She viewed these responses as diminishing her concerns rather than acknowledging the seriousness of the event.
She also alleged that the crew continued speaking to her despite her requests for space. She said she felt uncomfortable when advised to meet the Captain and First Officer in the cockpit, considering the circumstances.
Chatterji noted that she spent the ninety-minute flight feeling distressed and isolated. After arrival, she emailed senior IndiGo leadership, including the CEO. She said the follow-up consisted of scripted calls and a formal apology. Compensation offered included a refund and travel vouchers, which she felt reduced the issue to a financial matter instead of addressing protocol failures.
Her stated objective in posting the account was to highlight gaps in accountability that can affect women and families traveling with young children.

Public Apology
IndiGo (6E) issued a public apology on LinkedIn, calling the occurrence an inadvertent mistake. The airline said it counselled the involved crew member and would reinforce internal training to prevent similar incidents. IndiGo stated that it treats passenger safety, dignity, and comfort with high priority.
However, many LinkedIn users criticized the wording of the response. Comments focused on the belief that privacy breaches cannot be classified as minor events.
Several users noted that lavatory lock indicators are designed to prevent such occurrences and suggested that stronger operational controls are needed.
