The business class cabin is really nice - EXCEPT the two interior seats have no divider between them - which makes for a bad experience -especially when the person next to you coughs excessively with no protection. Basically, the person is looking at you and coughing at you the WHOLE FLIGHT. Most major airlines have a sliding divider you can close for privacy and safety reasons. The window seats do not have this problem - so if you book business class and are traveling solo - make sure to get a window seat - I didn't and regretted it.
