I'm a fan of first class when I have the points or a company offers it for a business trip. But on my own dime, I prefer to fly coach and use the money either on food or hotel. I was wondering for long trips, do you have a preference. If I made more mdoney, I would always fly first class for any trip over eight hours. What about you? Do you think the space and service is worth the extra money or is it wasted?
