Long air travel can be tiring, but a few smart tips make it much easier. Stay hydrated by drinking plenty of water and avoid excess caffeine or alcohol. Wear comfortable clothing and consider compression socks to improve circulation. Move around the cabin and stretch regularly to prevent stiffness. Pack essentials like a neck pillow, eye mask, and headphones for better rest, and use apps like Google Maps or airline apps to stay updated on your journey. Keeping snacks, entertainment, and important documents handy will also help you stay relaxed and prepared throughout the flight.
