But only when they fly. When you are waiting that 30 minutes sitting in the plane after boarding, the fraction of re-breathed air can get high. People have measured 2000 and 4000 ppm CO2 readings.
- MichaelZuo 4y agoLooking from the chart it seems like the CO2 levels were elevated for the entire flight? As in it never dips below 1200pm on either the short haul or long haul flight. Also with the caveat in the article: "Note that the graphs below aren't calculated for altitude adjustment. Since planes are generally pressurized to an equivalent of 8000 feet, and senor drift is typically 3 per 1000 feet of elevation, it means that while in the air the CO2 levels are likely $24% higher than shown on the graph." It seems the logged numbers are underestimating it.
