First off, these windows are larger than you find on other commercial aircraft. The benefits of 19-inch windows include letting in more light and eliminating the need to lean forward to crook your neck to have a peek outside. But, if you prefer a little less light, don't reach for the shade; instead, go for the moon-shaped button directly below.
Thanks to an electrified gel sandwiched between two pieces of glass, the self-dimming windows adjust light and dark depending on preference. Cabin crew also has the power to adjust all windows at once, changing the cabin to undimmed for take-off and landing or completely dimmed for sleeper service flights to limit the effect of an early morning sunrise. Our snap above is somewhere around halfway dim, which is the perfect setting to block the sun's glare while still enjoying a view and perhaps a nap.
If you think we've put this picture through an Instagram filter, you'd be mistaken. It's an untouched photo, and that cerulean hue is all the effect of the window itself.
