ETA - I flew for years in the Air Force and if you're going up to altitudes below 10,000 feet, you should be ok unless you have a medical condition. Above 10,000 feet gets tricky. If you go higher and encounter breathing problems a can like that is unlikely to help for long and unless you can get down below 10,000 feet fairly quickly, it won't be of much use. However, if you're thinking of using it due to medical issues, you definitely should consult a doctor first.

My dad is 77 but has no breathing or heart issues. I am 50 and have COPD. I don't need oxygen but I have my worries and my doctor told me to get a portable concentrater and to get some of these. This is a bucket list trip for him and Alaska is on my bucket list.
