Related Notes:
I was upgraded to first class on an LA->Melbourne flight last year! Although I can't say it was especially better than business class, it was really something: the seat spun a little, I had pasta and a delicious sweet wine, and got excellent sleep.
My third business class flight (BLR-HKG Dragon Air on a A330) was kind of like the first in the recliner and the way the holes under the back of each seat are where the feet go. It was pretty good.
My fourth business class flight (HKG-MEL Cathay Pacific on an A350) was something very special, because of the way each seat had its own space diagonally, fully separate from other passengers. I had what was both an aisle and a window seat (like the first flight) but this time I got to recline to be fully horizontal, and got a solid 5 hour sleep. Pretty amazing!
My first business class flight (MEL-SIN Qantas on an A330) was roomy. It's not life-changing, just far more comfortable. The reclining seat, the full table and service perks were great.
My second (SIN-BLR Jet Airways on a 737) was better than the equivalent economy, but really nothing special. Our entertainment option was still BYOD with a tiny selection, and the seats were wider but otherwise the same.
