I paid for first class and it was nothing more than a 36" long curtain between first and business class, nothing extra, nothing fancy and a waste of money. Would have been better off just getting a regular seat and saving the money. Also had one of my eardrums rupture because of the take off and had to sit in uncomfortable pain with a bleeding ear the entire flight. Had to go to the doctor and it's been 5 days and still having difficulty hearing like it just happened.
