Survive, yes. Mexico city is at an altitude of over 7,000 feet above the sea level, so the altitude, in itself, is not a problem. So let's look at altitude above ground: Passenger aircraft fly at 30,000 feet. And millions of passengers fly regularly. Again, no issue. The International Space Station orbits at more than 100 MILES above the ground. Even more proof that survival at altitude is not a problem. What IS a problem is keeping humans supplied with food and water and warmth at that altitude. If you can handle that you will survive.
The opposite to altitude is depth.
The altitude forms a right angle triangle with half the side length and one side as the hypotenuse. Using Pythagoras: (½side)² + altitude² = side² → altitude² = side² - ¼side² → altitude² = ¾side² → altitude = (√3)/2 × side → altitude = (√3)/2 × 6 = 3√3 ≈ 5.2
The A380 has a cruising speed of Mach 0.85 (about 900 km/h or 560 mph at cruising altitude), its maximum design speed is Mach 0.96.
Above 50,000 feet (15 kilometers)
The bar-headed goose flys at the highest altitude and reaches the highest altitude of any animal.
Helicopters fly somewhat close to the ground. They fly near the troposphere. They fly at a lower altitude than planes.
La Rinconada, Peru has the highest altitude in the world at 5,099 meters.
The highest altitude reached by a manned vehicle under its own (jet) power is 37650 metres, in a MiG-25M. This is essentially the highest a plane can go, short of strapping rockets on.
Maximun is 45,000 ft under ATC, Absolute Maximun is 60,000 without special permission from the FAA
At about 30,000 feet, the air is thinner and the aircraft has little resistance at that height, because of that little resistance the plane can fly much further
Better fuel economy. The air is thinner at higher altitudes.
Tibet
It is not, the highest altitude above Sea Level is achieved by the summit of Mt. Everest.

We will fly a VFR flight heading 245 - what is a legal cruising altitude?
