Qin Dong, a Chinese citizen and German resident, disappeared while sailing aboard AIDAluna during a Mediterranean cruise in December 2025. She boarded the ship as expected in Palma de Mallorca on December 10, but never made it home.
What followed has raised difficult and unsettling questions. With no clear explanation and urgent pleas from family and friends spreading online, her disappearance has left many wondering what could have happened during what should have been a routine cruise.
A Normal Cruise That Wasn’t
Qin Dong boarded AIDAluna shortly before noon on December 10 for a five-night Mediterranean cruise. The itinerary was familiar and popular: Palma de Mallorca, a sea day, Marseille, Palamós, Barcelona, and then back to Palma. From a cruise perspective, this was a routine sailing with nothing unusual reported at embarkation.
Cruise lines keep detailed boarding records, and AIDA Cruises has confirmed that Qin Dong did board the ship as scheduled. At that point, everything appeared completely normal.
The Marseille Timeline Raises Questions
Thursday, December 11, was a full sea day, meaning all guests remained onboard. The following morning, AIDAluna arrived in Marseille at approximately 8 a.m. Onboard records later showed that Qin Dong did not officially disembark in the French port.
That detail matters because cruise ships log every passenger leaving and returning at ports of call. If a guest fails to return, the ship usually knows almost immediately.
What complicates the timeline is that friends were still exchanging messages with Qin Dong at nearly 8 p.m. on Friday evening—roughly two hours after the ship had already departed Marseille. This strongly suggests she was still onboard after leaving port.
Not a Missed-Ship Scenario
When cruise passengers go missing, the first assumption is often that they missed the ship in port. In this case, that explanation does not fit. AIDA Cruises confirmed that Qin Dong never officially disembarked after boarding in Palma de Mallorca.
For cruisers, this distinction is important. Being left behind at a port is one of the most common cruise-related incidents—and one of the easiest to resolve. Qin Dong’s disappearance appears to have occurred while the ship was already at sea, which is far more concerning and harder to explain.
Miss the ship once, and your vacation changes fast—these are the cruise mistakes that leave people stuck in port alone.
No Overboard Alert or Emergency Response
According to available information, there were no emergency announcements, overboard alerts, or visible search operations during the voyage. AIDAluna continued sailing on its planned itinerary without delays or changes.
Cruise ships have procedures in place to respond to emergencies, but not every situation is immediately apparent to guests. In this case, there has been no indication that an incident was detected at the time Qin Dong went missing.
Onboard records also indicate that only one drink was charged to her account during the cruise—an orange juice—with no alcohol purchases logged.
Family and Friends Turn to Social Media
When AIDAluna returned to Palma de Mallorca on December 15 without Qin Dong onboard, her family and friends began urgently looking for answers. Messages quickly spread across social media, asking whether anyone had seen or spoken with her during the cruise.
They’ve said that even small details could matter — a short conversation, noticing where she was sitting, or spotting her on deck. For anyone who was onboard, those everyday moments might now help fill in the gaps.
Why Three Countries Are Now Involved
This case crosses borders. French authorities were notified because the ship was in Marseille when Qin Dong was last known to be onboard. Chinese authorities are involved due to her citizenship. German authorities are also engaged because AIDA Cruises is a German cruise line and Qin Dong was a resident of Germany.
For travelers, this explains why cases like this can take time to resolve. Multiple jurisdictions mean more coordination, which can slow the process even as the search continues.
What This Means for Cruisers
Cruising is still widely considered a safe way to travel, and situations like this are extremely uncommon. Even so, Qin Dong’s disappearance shows that not every case has immediate or clear explanations, even on modern cruise ships.
For now, there are more questions than answers. What happened after AIDAluna left Marseille, and did anyone see her later that evening? Until more information becomes available, efforts remain focused on finding Qin Dong and supporting her family and friends.
