A red-eye flight is any flight departing late at night and arriving early the next morning. The term red-eye derives from the fatigue symptom of having red eyes, which can be caused or aggravated by late-night travel.
A red-eye flight typically moves east during the night hours. It departs late at night, lasts only about three to five hours, an insufficient period to get fully rested in flight, and due to forward time zone changes the aircraft lands around dawn. As a result, many travelers are unable to get sufficiently rested before a new day of activity. From a marketing standpoint, the flights allow business travelers an opportunity to migrate eastward without having an impact on a full business day.
Most eastward transatlantic crossings from North America to Europe are operated overnight, but are generally not viewed as red-eye flights since they depart early in the evening and last at least seven hours. A full night's rest is theoretically possible as this is close to the seven to nine hours of nightly sleep recommended by the US National Sleep Foundation.

Famous quotes containing the word flight:
“Its shrill scream seems yet to linger in its throat, and the roar of the sea in its wings. There is the tyranny of Jove in its claws, and his wrath in the erectile feathers of the head and neck. It reminds me of the Argonautic expedition, and would inspire the dullest to take flight over Parnassus.”
—Henry David Thoreau (1817–1862)
