Make Yourself Comfortable
Most economy class seats barely recline. If you're going to attempt to sleep on the plane, invest in travel pillows that mimic the way you sleep naturally. If you're a side sleeper, choose a pillow that lets you tilt your head to one side, and if you tend to sleep on your stomach, choose one that sits on the tray table for you to lean forward onto. Elliott also recommends bringing an eye mask on board to block out light and signal to others that you don't want to be disturbed. Or, bring a light down jacket that you can wear if you're chilly or repurpose as a pillow when it's time to rest.
