A survey of 54 airlines showed that, although some airlines provided therapy free of charge, others charged fees ranging from £48 to £544. Most of the airlines insisted patients bring their own oxygen on board, rather than providing it themselves.
The British Lung Foundation is currently calling for all airlines to remove charges for providing oxygen and letting patients bring oxygen onboard.
Helena Shovelton, chief executive of the charity, said: 'Supplemental oxygen is as important to people with breathing problems as a wheelchair is to people who have difficulty walking.
'All airlines should allow people dependent on supplemental oxygen to travel with it free of charge, if they have medical clearance to do so.'
MPs have also called for an end to fees for in-flight oxygen. So far 84 MPs have signed an early-day motion calling for such charges to be scrapped.
The motion was tabled by Nick Ainger, Labour MP for Carmarthen West and South Pembrokeshire.
