It is stronger per weight and volume than steel.
For super-high-speed airplanes (SR-71 Blackbird for example) it also resists heating better, the metal does not get as soft when it is heated. These planes fly so fast that the air literally heats the leading edges of the wings to several hundred degrees.
But, it is expensive and hard to work with. Most small planes just use aluminum. I'm pretty sure commercial jets also use aluminum, restricting the titanium only to critical parts of the engines.

Titanium is a transition metal which is very strong and light (4.4 gm/cm^3). It has a high melting point (1800°C) and finds application in aircraft wings, particularly at points which are subjected to the high heat of exhaust.

High strength-to-weight ratio
excellent resistance to corrosion because the top layer will oxidize and form a protective coating, very important in airplanes
The tensile strength is equal to that of intermediate strength high strength low alloy steels
43% lighter than steel
It is usually alloyed with vanadium when used in the outer skin of aircraft

Strong and light weight.
Also good at protecting you from projectiles. The pilot in the A-10 sits in a "titanium tub" for extra protection.

I'm not sure if this is entirely accurate, but my meterology teacher told me that metal expands and contracts in regard to air temperature. Maybe titanium doesn't expand a lot when it gets colder up there.

Because Titanium is very light, and i think its very areodynamic. I dont know about the second part, but i know it is very light.

Because it is light and strong.
