Should I wear the airline-provided pajamas?

Yes. Changing into provided sleepwear signals your brain that it is time to rest, which helps reduce jet lag upon arrival.

Can I bring my own alcohol into the lounge?

No. Never bring outside alcohol into an airline lounge; it is a violation of most lounge policies and will result in your removal.

Is it rude to ask for more pillows?

Not at all. Ask early in the flight, as there is a limited supply. If you ask after the lights go out, they are likely already gone.

How to get the most out of your business class flight

Treat your business class ticket as a service package rather than just a seat. Arrive at the airport three hours early to utilize the lounge for dining and showering, and communicate your specific sleep needs to cabin crew immediately upon boarding.

Utilize the lounge for your main meal. Airport lounge food is often higher quality and less rushed than in-flight service. Eat your primary meal in the lounge so you can skip the in-flight dinner service and go straight to sleep once you reach your cruising altitude.
Secure your sleep window. As soon as you board, tell the flight attendant: 'I’d like to prioritize sleep and skip the meal service.' Ask them to place a 'do not disturb' tag on your seat or skip your row during the wake-up breakfast service if you need extra rest.
Use the amenity kit strategically. Don't just open the bag. Use the provided eye mask immediately to block out cabin lights, and use the provided moisturizer or lip balm before takeoff, as the cabin air drops to 10-15% humidity and dehydrates you rapidly.
Optimize the seat settings. Before you recline, adjust your lumbar support while sitting upright. Most business class seats have a 'bed' button, but manual adjustments to the leg rest height will save your lower back during long-haul flights.
