$200 seems really expensive for KWI-DXB. As a comparison, I got an offer to upgrade COK-DXB (4.5 hours) for $350, which I thought was an okay deal, and DXB-SFO on the A380 (15 hours) for $1000, which I thought was a great deal. Not sure how much the upgrade offer dollar amounts vary on the same route - this was my first time getting them.
