I suffer from low blood oxygen levels due to COPD (Used to be called Emphesymea - wrong spelling!) - the problem is when flying by normal Airbus or Boeing at 38,000 ft, my oxygen level can go down as low as 79% - average 84%, against a norm of 94%, I monitor this by a calibrated Oxymeter clipped onto a finger - this can be worrying over a 2+ hour flt LHR to Oporto, it seems to be a feature of current large aircraft to operate with minimum levels of oxygen, (cost savings?).
Recently I flew to SOU - Jersey by Dornier 28?, which flew at 15,000 ft, magic - no problem, oxy level 94% all the way. Now I wish to fly from SOU to Perpignan on Flybe, can anyone tell me if the cabin air is likely to become pressurised such that the oxygen content will go down?, I understand that Flybe only use Dash 8-400's.
Cheers
