Falling asleep in economy class requires a "survival kit" and a strategy focused on sensory deprivation and physical support. First, your seating choice is vital: always aim for a window seat, which provides a solid wall to lean your head against and prevents you from being woken up by seatmates needing to move. To combat the noise and light of the cabin, high-quality noise-canceling headphones (playing white noise or calm music) and a contoured eye mask are essential. For physical comfort, don't rely on the airline's thin pillow; instead, use a supportive neck pillow (like the "trtl" wrap or a memory foam version) and consider placing a small rolled-up jacket in the small of your back for lumbar support. To improve circulation and reduce the "restless leg" sensation, use your carry-on bag as a footrest to slightly elevate your feet. Finally, dress in loose, breathable layers to account for the cabin's fluctuating temperatures, and avoid caffeine or heavy meals for at least three hours before your planned sleep time. Setting your watch to your destination's time zone the moment you board can also help your brain psychologically prepare for rest.
