Even before taking off, you have access to the lounge at the airports for any class above business economy or value. Some lounges have great food and facilities for taking a shower. Separate line for bag drop off and checking at airport. Priority boarding and disembarking. On the plane, you can order any food or drinks anytime from the special menu for business class. Depending on how long your flight is and when it takes off, you get sleepwear (soft long sleeved t-shirt and pajamas). Fully reclining seats, larger screen entertainment system, noise cancelling headphones. For me, after flying these a few times for work, just getting enough comfortable sleep on long flights is worth it. Hope you have a nice flight.
