The air was pretty nasty flying in the 70's when smoking was permitted . I would have a splitting headache from flying . I bet the oxygen was 15% or less . Can anybody explain what type of breathing systems our commercial airlines use today.

Pretty darn clean. O2 never approached 15% even in the 70s.

Learn how aircraft cabin air filters offer exceptional cabin air quality by ensuring dust, fibers, bacteria, viruses, Volatile Organic Compounds (VOCs), and odors are removed from the recirculation air stream.

OP
I still will analyze the air myself and long flights

i love that this is in the "compressors, boosters, and blending systems" forum
And what are you going to do about it? Open an O2 tank at your seat?
I suggest that you travel by ocean liner henceforth.
How do you intend to analyze the air?
The air you breath will always be 21% oxygen

Commercial aircraft are pressurized, most to about a 9 psi diff, if the aircraft is at 30,000 feet altitude, the cabin will be at about 8000 roughly, varies per aircraft but you get the idea. O2 level is not a problem, the air you are flying in, and the condition of the engines is.
Filtering is only done on recirculated air in the cabin, the initial pressurization air is straight from the engines, through the air conditioning equipment, to cool it, and then on into the cabin.
Newer aircraft like the Boeing 787, don't use air from the engines to pressurize, they use electric driven air compressors, and other measures to make the flight more comfortable.
