Wow. That is fascinating. Just on international flights, I wouldn't be able to count. If I can take a train, I would definitely do so. When i cross from the UK to Europe, I definitely prefer busses and ferries, thought I have been guilty of flying. And I would not consider myself rich. It's just that, whenever I change countries to go live somewhere else, I have to fly. I relocated from South Africa to Germany about 6 weeks ago.
