The benefits of flying first-class are obvious: more legroom, more comfortable seats, improved on-board service, and so on. All of these amenities, of course, aren't cheap. As a result, the age-old question of whether flying first class is worthwhile emerges. It is sometimes worthwhile to spend a higher fee for a better seat, and other times it is not. But, in any case, when you can pay for it with points and miles, that seat feels so much better!
