30,000 TO 35,OOO FEET ==Addendum== The above answer applies to modern commercial type jets. Smaller business jets can easily cruise in the 45,000 to 50,000 feet range. The Concord cruised at around 55,000 feet with a maximum cruise altitude of 60,000 feet. Military jets, of course, operate at various altitudes depending on design mission.
