LATAM Airlines Diversion: Passengers Stranded in Mendoza Amid Operational Failures

What begins as a routine domestic flight can quickly devolve into an international ordeal when operational lapses collide with poor customer service. This was the reality for nearly 200 passengers on LATAM Airlines flight LA137, which was diverted from its Santiago destination to Mendoza, Argentina, leaving travelers stranded in a foreign country for nearly 20 hours.

The incident has sparked a debate over airline accountability, the efficacy of automated customer support, and the legal rights of passengers when “operational procedures” result in significant personal and financial distress.

The Timeline of Flight LA137

On April 30, 2026, flight LA137 departed Antofagasta bound for Santiago. While the flight experienced a minor initial delay of approximately 45 minutes, the situation escalated as the aircraft approached its destination. Due to high traffic and ongoing maintenance on one of the runways, the pilot announced that the plane could not land in Santiago and would instead divert to Mendoza, Argentina.

Passengers landed in Mendoza around 11:00 PM. Although initial communications suggested a midnight departure back to Chile following refueling and safety checks, those plans collapsed. The return flight was ultimately postponed until 5:00 PM on May 1, 2026.

“The plane began to circle, and suddenly the pilot announces that… We couldn’t land, so the flight would be diverted to… MENDOZA! The nightmare begins for a flight with almost 200 passengers.”

A “Nightmare” Experience: Bot Support and Missing Hotels

For many on board, the diversion was only the beginning of the frustration. According to John Atkinson, who shared his experience on LinkedIn, the airline’s ground support was severely lacking. Passengers were directed to hotels starting around 4:00 AM on May 1, yet nearly half of the travelers found themselves without accommodations.

The crisis was exacerbated by the airline’s reliance on automation. Passengers seeking explanations or assistance were reportedly directed to a customer service phone line managed by a bot. While some travelers received support, others were forced to stay at the airport or arrive at hotels only to find there were no available rooms.

In several instances, passengers were told to pay for their own hotels, transportation, and meals out of pocket with the promise of a later reimbursement. While LATAM has since reimbursed Dr. Atkinson for his specific accommodation costs, the experience has led a group of affected passengers to evaluate legal action for damages.

The Airline’s Defense vs. Regulatory Reality

LATAM Airlines attributed the diversion to congestion at the Santiago airport, citing a combination of a runway closure for maintenance and an emergency declaration from another airline’s aircraft. The company maintains that it activated “assistance protocols” to support passengers in Mendoza and coordinated a special recovery flight, LA1101, to transport the group to Santiago on the afternoon of May 1.

However, the Dirección General de Aeronáutica Civil (DGAC) has clarified that the decision to divert to Mendoza rested exclusively with the airline, based on its own operational and safety procedures.

Understanding the NOTAM System

A critical point of contention is whether the airline should have anticipated the runway restrictions. The DGAC confirmed that maintenance work on the Santiago runways had been communicated to all airlines late last year and reiterated throughout 2026.

This communication was handled via a NOTAM (Notice to Air Missions). A NOTAM is a standard aviation tool used to alert pilots and operators of potential hazards or changes in facility availability—such as closed runways or updated navigation procedures—that could affect flight safety. Because the NOTAM was active and the dates were consensually agreed upon, the runway maintenance was a known variable, not an unexpected surprise.

sources close to the case suggest the extended delay in Mendoza—stretching from midnight to the following afternoon—was caused by the flight crew exceeding their legal duty hour limits, effectively grounding the plane until a fresh crew or a new schedule could be established.

Key Takeaways for Travelers

• Document Everything: If you are forced to pay for hotels or meals during a diversion, keep every single receipt and record all communications with the airline.
• Know Your Rights: Diversions are often legal for safety reasons, but the airline’s duty of care (food, lodging, and communication) remains mandatory.
• Beware of Bots: When automated systems fail during a crisis, seek out physical representatives or use social media to create a public record of your request for help.
• Check the “Why”: Understanding if a delay is due to “force majeure” (weather) or “operational failure” (crew hours/scheduling) is vital for successful compensation claims.

As passengers move forward with potential legal action, this case serves as a reminder that while aviation safety is paramount, the “duty of care” provided to passengers on the ground must be as robust as the safety protocols in the air.
