A red-eye flight is a late-night or overnight flight that typically departs late in the evening and arrives early in the morning. The term “red-eye” refers to the fatigue or redness in the eyes that passengers may experience due to lack of sleep during these flights. Red-eye flights are commonly used for long-distance travel, allowing passengers to maximize their time at their destination by flying overnight and arriving the next morning. These flights are often chosen by travelers who prefer to sleep during the flight and avoid daytime travel.
