The plane continued to climb in altitude, and Luofeng's heart grew increasingly tense.
Because he had already noticed the middle-aged man on the right was dozing off.
This was not normal; the man was experiencing oxygen deficiency.
Such situations were more common in the economy class because there are more passengers, resulting in more serious oxygen deficiency.
The real issue with this plane wasn't the air conditioning malfunction but the pressurization system. The cabin's pressurization system wasn't functioning properly, causing the cabin to slowly depressurize.
It's like experiencing altitude sickness in highland regions.
Luofeng checked the multimedia system in the first-class cabin. The plane's altitude had already reached 6,000 meters and was still ascending, while commercial airplanes typically fly between 7,000 and 12,000 meters.
Imagine the altitude sickness at such a height.
