I'm sorry what? I never heard of this. How do you think that will save money?

I believe, and we do have some commercial pilots on this forum that most commercial flights are pressurized between 6000-8000ft above sea level. So that is lower than normal pressure for someone from Florida could be a bit higher than normal for someone from Denver. So, if you have lung problems you could perhaps suffer from mild hypoxia. However, I don't think drowsiness is a symptom of that.

  • Air Hunger
  • Dizziness
  • Headache
  • Mental and Muscle Fatigue
  • Nausea
  • Hot and Cold Flashes
  • Tingling
  • Visual Impairment
  • Euphoria
