“How do you sleep better on a plane?”

To sleep better on a plane: choose a window seat, use a neck pillow, eye mask, and earplugs to create a comfortable environment, establish a pre-flight relaxation routine, adjust your sleep schedule to the destination's time zone, limit caffeine and alcohol intake, stay hydrated, consider sleep aids if needed, practice relaxation techniques, and find a comfortable seat position. It may take some experimentation to find what works best for you.
