Compared to prices that airlines charge for seats in economy class, the extra money you'll have to spend is definitely justified. You'll enjoy considerably more space, eat better food, benefit from better service, and usually have a lie-flat seat that allows you to sleep during your flight. After a 12 hours flight in economy class - maybe even overnight - you'll often need a day or two to recover. But if you got some shut-eye on the plane, you can be productive right from the start. That's why business people tend to fly in premium cabins. And it's also where the name business class comes from. If you're the type of person that travelers once or twice a year for pleasure, it might be better to invest the money into a better hotel. Since you'll spend more time there.
