I'm flying on OZ 221/222 leaving this week from JFK to ICN and back. My company paid for me to fly economy, but I ponied up my own money for the upgrade to business class.

Can anyone fill me in a bit on the experience I should expect? Was it worth the several grand I paid to upgrade?

This is my first flight greater than 6 hours - so I'm quite nervous right now. Any information would be helpful!

Thank you!!!
