A disturbing incident occurred at Barcelona Airport where a couple left their ten-year-old son in the terminal after discovering that his passport was expired.

The family was en route for a summer vacation, but upon arrival at the airport, the parents decided to proceed with their travel plans instead of delaying their flight.

Reports indicate that a relative was to be summoned to collect the child from the airport.

The incident unfolded on a Wednesday, as narrated by Lillian, an airport flight attendant who shared the story on social media.

She highlighted that the child was not allowed to board the flight due to the expired passport, which necessitated a visa for entry into their intended destination country.

The child was reportedly traveling with a Spanish passport, but the visa issue resulted in the family's decision to leave him behind while they boarded their flight.

Lillian noted that the relative was expected to arrive at the terminal within a time frame ranging from half an hour to three hours.

Shortly after, airport staff discovered the child alone in the terminal and promptly notified the authorities.

According to reports, the child had informed staff that his parents were already on the airplane.

The police, upon learning about the situation, communicated with the flight crew, inquiring over the intercom if anyone had left a child in the terminal.

However, no one answered the call.

Eventually, the officers located the parents on the plane, where they were traveling with another child, who reportedly had valid travel documents.

Subsequent to the discovery, police escorted the parents and their other child off the aircraft to a police station where the abandoned child was waiting.

Witness accounts suggest that the parents viewed their decision to leave their child as completely normal.

The identity and nationality of the family remain unknown, and it is currently unclear whether any legal action will be taken against the parents regarding this incident.
