That all said.... is it worth the extra 2-3000 dollars for QF??
ANSWER....????
In my opinion business/first class are the most overpriced services you can buy. Let's face it for the extra you get a lay flat seat and a decent meal. A room in a decent hotel costs about $350 night and a decent meal with wine would not be more than $200, yet we pay a $4000+ premium to fly in business and an even more ridiculous price for first.
But if people are willing to pay then why not charge whatever you can? After all business is about making money!
