What a wonderful story! Unfortunately, the jackasses always make the news and the good guys usually don't. Most flights I've been on, especially in the U.S., have good-hearted people who are willing to help fellow pax. Whether it's helping someone stow their bag, switching seats so families can sit together, helping someone on/off with their coats, etc., it really warms the heart. It always makes my day when someone helps me and I always try to return the favor.
