Many airliners glide quite well - they can glide quite a bit further from a given altitude than can general aviation aircraft that are (probably) more likely to run into a scenario where they'll need to glide. Air Transat 236 managed to glide 120km and land safely after running out of fuel. The Helios flight in 2005 was unfortunate. The flight attendant trying to control it had some pilot training, but not enough to handle an out-of-fuel airliner at relatively low altitude.
