Some can, some cannot. It is best in either case to simply avoid such weather by flying around it as the air above these storms is still likely to be very turbulent.
Air
they fly
Jet aircraft generally fly above FL300 (30,000ft) to maximise efficiency. Not just fuel efficiency but also to minimise flight time.

Jet airplanes fly at high altitudes because it is more fuel efficient. Flying at higher altitudes uses less fuel than flying at lower altitudes.
ALL aircraft fly in the Troposphere regardless of distance.
Jet exhaust, which is now mostly hot air.
Sometimes yes, but often no. Tornadoes form during severe thunderstorm, extending from the ground up to cloud bases and a good deal above that. Even aside from the tornado, thunderstorms can contain dangerous winds, hail, and icing conditions that planes should avoid. While jet airliners can safely fly over some thunderstorms, the storms that spawn tornadoes are often very tall and their heights can exceed the flight ceilings of commercial aircraft.
Airplanes use air for lift and for thrust. If there's no atmosphere, they can't fly. Even a jet engine needs to burn and compress air.
on airplanes yes... in space sort of... if you had a jet pack... but sadly people can't fly like birds yet. =(
Commercial, jet engined aircraft, such as the 747, fly at approximately 40 000 feet. Propeller aircraft fly at lower altitudes
Cirrus clouds only form at high levels, so jet plaanes fly at super high levels.
