Wait, does she have altitude sickness from flying or from being in Park City? I dont think I've heard of people getting it solely from flying, given airplanes are pressurized and oxygenated.

It took me about a day to get used to it when I was in Bogota but I was fine after that. It was terrible I think from a combo of being exhausted/getting my period/elevation. Which was fun. But when I came back after being in lower cities, I didnt have a problem. I went to a little community up higher and besides feeling out of breath if I walked too fast, I didn't feel sick.
