Wow Rainboe, you seemed to operate in a pretty confined world for a longhaul pilot. While your comments are certainly true concerning India in rush hour, they fail to hold true in much of the world, or even over India in off peak times.
As to a number of peoples comments about the accuracy of computer flight planes, true, often. Had a twenty-five knot stronger headwind than forecast on a KMEM PANC leg last week, and that is in the part of the world with good weather forecasts and reporting. More then once I have found the weather forecast worse than useless at the end of an eight hour flight (admitadly a bit off of the original topic).
