FAA regulations require oxygen for flights above 10,000 feet for more than 15 minutes. Commercial flights, even at 35,000 feet MSL, are pressurized to 7-8000 feet MSL under normal circumstances.
I live at sea-level. I fly quite a bit for business, using both the big jet planes and small (unpressurized) general aviation aircraft. I have experienced CH-attacks on both types of flights. The ones I remember most were the ones that occured shortly after we reached cruise altitude (effectively 7-8000 MSL). I have surrendered my FAA medical certificate due to CH. I don't feel that I should be pilot-in-command during a CH-attack. When not in a cycle it is OK and I have logged a bunch of hours, but I never know when they are going to happen, so I let the FAA win that argument, for now.
I have come to the conclusion that ANYTHING can and will trigger a CH-attack when in a susceptiple state. (Like Texas). They have a mind of their own and just happen to happen in my head. I have decided to just live life the best I can and not let them rule me.
