Up to about 60000 feet. Concorde used to cruise at about 50000-60000. Airbus and boeing usually fly at about 30000-42000 feet.

It is not that jet engines perform better at higher altitude, but rather they are more fuel efficient. Performance is far greater at lower altitudes. Just think about when you are taking off and the airplane accelerates quickly and pitches way up. There's lots of extra thrust down low to allow that. The fuel/air ratio remains somewhat constant through the climb. As altitude increases, the air thin outs and therefore, so can the fuel flow. Airlines try for the most efficient routes and altitudes as possible to save money. They do however change altitudes in flight (higher or lower) when needed for weather and turbulence avoidance. --- And a note about the jet stream, it is relatively narrow and always curving, so the time an airliner would spend there is very short. And another thing, it flows mostly west to east isn't the U.S. so a westbound flight would be at a disadvantage. Airlines still fly high whether traveling East or West.

35,000 miles? Blimey.
Most passenger planes have a max altitude of 40 - 45,000 ft depending on model. This will be the certified altitude but the manufacturer will test to higher altitudes than this.
Concorde used to have a max altitude of 60,000 ft.

The current highest flying passenger plane is the Cessna Citation X (ten). It is certified to a ceiling of 54,000 feet. --likely could go higher on a good day with favorable temperatures but then you'd become a test pilot.

Most commercial airliners will not cruise above FL 450 (approx 45000 feet) - although they will have been tested above that during trials.
Upper limit of Class A airspace in the UK is FL245 (24,500') - above that you get into Upper Airspace, within which there are a series of Upper Air Routes with a ceiling of FL 450 - above that the airspace should be controlled by the Military.

35,000ft to about 50,000ft. Depends on the aircraft. I beleive the larger the plane, like B - 777 is pretty large and can fly high.
At least I think so because when I flew on Korean Air and the aircraft was a B - 777, it made it about 40,000 feet.

35,000 - 40,000 feet. Altitude depends on the plane.

a passenger aircraft can fly around 35,000 ft to 55,00 ft
