I have a Respionics Simply Go POC that has pulse and constant flow capabilities and have flown overseas several times w/o difficulty and one of my sons lives in Montana at 4000 feet an have spent time in Butte at 8000feet w/o difficulty.  I use continuous flow at night and pulse during the day.  I have flown with Delta and United and overseas carriers, initially,I needed a medical clearance, but more recently I filled out a form with the name of the POC
