Flying to the other side of the world means almost a full day in transit. Here are three tips to help you get through your next long flight:

• Drink plenty of water. It’s easy to forget to drink water on a plane. I usually ask the flight attendants for two glasses of water. This has the side effect of also making you stand up and exercise once in a while, which is good for avoiding deep-vein thrombosis.
• Bring noise-isolating earphones. An eye-mask is also helpful. You can usually plug the earphones into airline seats, giving you better audio than the earphones provided by the airline.
• Bring a variety of things to do. A pen, a pad of paper, and an MP3 player will keep you busy throughout the flight.
