Do not hang locks on suitcases and bags. They can be easily opened, so protection is minimal.
Take your own headphones on board. The ones you get on the airplane may be of poor quality.
Dress more comfortably. The comfort of the flight will depend on how comfortable you are in your clothes. So leave the tight dress and stilettos until better times.
Bring thermal water for your face. The air on board is very dry and your skin needs to be moisturized from time to time.
