While the exact cause of the crash has not yet been verified, multiple tweets have pointed out the same aircraft’s emergency landing from the day before.

According to Aviation Source News, HL8088 was en route to Beijing on December 27, 2024 (KST) when it declared an emergency before diverting to the Incheon International Airport.

Jeju Air flight 7C8135, operated by a Boeing 737-800 was en route to Beijing Daxing International Airport (PKX). The aircraft was performing a scheduled service from Jeju International Airport (CJU). The aircraft was on a cruising flight transiting the Yellow Sea when the flight crew declared an emergency. A descent and diversion to Incheon International Airport (ICN) was then carried out.

Based on this information and other flight records showing that HL8088 did indeed divert to Incheon, some jumped to conclusions—suggesting that there might have been a mechanical issue with the aircraft…

…and even blaming the “big corporations putting the almighty dollar over human lives.”

According to South Korea’s EKN (Energy Economic News), however, HL8088’s emergency landing on December 27 had nothing to do with the aircraft itself.

On December 28, EKN confirmed that the Jeju Air flight 7C8135 on Boeing aircraft HL8088 departed from Jeju International Airport at 11:51 AM and was scheduled to pass over the West Sea, Yantai, and Tianjin—but turned toward Incheon International Airport at 12:55 PM before entering mainland China. Subsequently, at 1:15 PM, the captain declared an emergency and squawked “7700,” a transponder code signaling that an aircraft is experiencing a general emergency and requires immediate assistance from air traffic control (ATC).

One representative from the Incheon International Airport Police Investigation Division told EKN, “There was a Chinese passenger who complained of head and chest pain.” A Jeju Air representative added, “[the said] passenger lost consciousness at the time, prompting the emergency landing.”

During this process, the cabin crew’s first aid efforts helped the passenger regain consciousness. The aircraft landed at Incheon International Airport at 1:28 PM, and the passenger was transferred to a hospital.

EKN reported that at 3:39 PM, HL8088 took off again from Incheon Airport and arrived at Daxing Airport at 4:33 PM.
