Answer: No.The cabin is pressurized between 6,000 and 8,000 feet on long flights. Adding supplemental oxygen is not necessary, because the percentage of oxygen is the same as being on the ground at those altitudes.

The air on a plane contains less oxygen than the air we normally breathe in.This leads to lower levels of oxygen in the blood. If you do not have a lung condition, the drop in oxygen is not enough that you would feel the difference.
Airlines “pressurize” the air in the cabin, but not to sea-level pressures, so there's still less oxygen getting to your body when you fly, which can make you feel drained or even short of breath. The potential dehydration factor and sitting for long periods of time doesn't help.
Typically, the airplane pressurizes to counteract the drop in air pressure at high altitudes. However, oxygen masks provide redundancy. If anything happens to the pressurization system, or the plane experiences any difficulties while in flight, oxygen masks will deploy.
Low air pressure during air travel also decreases the amount of oxygen in the air. This effect is modest and generally not noticeable for healthy travelers. For patients with significant lung disease, a small decrease in available oxygen can cause significant symptoms, especially with exercise.
Anyone travelling in an aircraft will have a drop in the amount of oxygen getting into their blood, although they are unlikely to feel any different. When you have a chronic lung condition this can make your chest symptoms worse. You may feel more breathless, your chest may feel tight.
Without oxygen, you will quickly feel drowsy and even euphoric, a phenomenon known as hypoxia, but as time passes, continued lack of oxygen to the brain will lead to blackouts, passing out, and possibly even death.
Even at 3,000 feet, there is a 10% drop in barometric pressure, and therefore a 10% drop in the number of oxygen molecules for each breath you take. Passenger airplanes are usually pressurized to between about 6,000 to 8,000 feet when the plane is cruising at 36,000 feet.
Values >95% on room air suggest that inflight hypoxemia is unlikely and that further evaluation is likely not necessary. Patients with saturations <92% on room air at rest should receive supplemental oxygen inflight, because they are at high risk of hypoxemia at altitude.
For most passengers, even those with respiratory disease, air travel is safe and comfortable. Some patients with COPD may be at risk but, with screening, these patients can be identified and most can travel safely with supplemental oxygen.
Choose a seat in the middle of the plane. As the air circulates across the rows and not up and down the plane, some experts believe the worst air is in the front or the back of the plane. Stay well hydrated by drinking lots of fluids (water or fruit juice) and avoiding caffeine and alcohol, which will dehydrate you.
Air pressure is lower at higher altitudes, which means your body takes in less oxygen. Airlines “pressurize” the air in the cabin, but not to sea-level pressures, so there's still less oxygen getting to your body when you fly, which can make you feel drained or even short of breath.
The cramped conditions and long periods of being less active on a flight can cause pain, stiffness or swelling of your legs. Being less active can lead to slow blood flow in your veins which increases your risk of developing a blood clot, known as deep vein thrombosis (DVT).
The primary problem is low oxygen, says Professor Frances Ashcroft, a physiologist at Oxford University. Low pressure would cause little more than discomfort in the ears and eyes, but the associated drop in oxygen levels makes people pass out if they do not put their oxygen masks on within about 15 seconds.
When you fly on an airplane, the flight attendant instructs you to “put your oxygen mask on first,” before helping others. Why is this an important rule for ensuring survival? Because if you run out of oxygen yourself, you can't help anyone else with their oxygen mask.
The airline may charge you for any oxygen it supplies during the flight. You will likely have to pay for oxygen for each leg of a trip. And airlines usually do not supply oxygen during layovers, so try to book a direct flight. At least two weeks before your flight, notify the airline that you will need oxygen.
