We each have to decide what is important for ourselves.

Yes the food is better, but it's hardly gourmet. And if alcohol is your drug of choice, then FC gets you it for free.

Their is much more room, and you get better treatment.

Is worth the extra miles? Thats for you to
decide.

In terms of dollar per mile, upgrades get you more, but the assumes you would have paid the dollars.

Ask yourself, would you rather take 2 free trips in coach or one free trip in FC?
