I am sure this has been discussed in other conversations but I can't seem to find a distinct thread on this topic. We are considering going on a trip from Western North America to South Africa. I know, quite crazy...but it is several months away, we would be able to pace while there and the opportunity is a bit of a 'once in a lifetime' situation. My sense is that it is way beyond me but I am still hopeful. I have heard a lot of 'you've got to be kidding' responses, and I do get that.... but are there any ways to modulate the impact of air travel? Do you think carrying supplemental oxygen would help? Last time we travelled I organized all the wheelchairs etc which helped a great deal but this length of air time is concerning. Two long, long flights. Would it be best to just push through and then give myself time at the other end to recuperate or would a two day break in the middle of the flights be better? Any tips and tricks out there?
