When you have scheduled the world’s longest flight of 19 hours and 9,000 nautical miles, one of your concerns should be passenger comfort. It is a long time to be sitting in a seat. That is why this is good PR. Singapore Airlines is redesigning seats in economy to be roomier and more comfortable. It is something one wishes other airlines would take for a model, but they are more concerned for the bottom line than the person. Admittedly, if the carrier tried to ferry people in the usual Airbus economy seating, they would probably lose passengers and be dealing with medical problems from people sitting so long in agony. But still, they are making an effort and that might be enough.
