How can I make an economy-class airplane seat more comfortable?

To make an economy-class airplane seat more comfortable, consider investing in travel accessories that enhance your flying experience. One approach is to optimize your seating and personal space. Bringing a travel pillow or neck pillow can significantly improve comfort during long flights. Additionally, wearing comfortable, layered clothing can help you adjust to changing cabin temperatures. Another strategy is to prepare for the flight by downloading entertainment content, such as movies or e-books, to stay occupied during the journey.
