Mike, Karachi to: Chicago: 6571 nautical miles Los Angeles: 7270 nm Houston: 7371 nm The 747-400ER has a range of 7670 nm and the Airbus 340-500 has a range of 8650 nm -- I got these from the Boeing & Airbus sites. I *think* these are the only planes capabale of any of these routes (short of the Space Shuttle). john -- John F. Kurtzke, C.S.C.
