A red-eye flight is any flight departing late at night and arriving early the next morning. The term red-eye, common in North America, derives from the fatigue symptom of having red eyes, which can be caused or aggravated by late-night travel.
A red eye flight is one which is too short to sleep on and thus causing significant distress to your optic nerves from fatigue. Flight time from Hong Kong to Seoul (3h30m)is a good example. Most flights from North America to Europe depart in the afternoon or evening, and arrive the next morning. The reverse journey, however, is usually in the daytime.

Russian airlines operate similarly to U.S. airlines by connecting Moscow to Yakutsk, Irkutsk, and Vladivostock. They last 5–8 hours but due to the northerly latitude the flights can cross as many as 8 time zones during this interval, drastically enlarging the time difference. The flights depart Moscow around 6 pm and arrive at the eastern cities around 6 am the next day. One of the current examples of red-eye flight is Aeroflot's SU783 from Moscow to Magadan, departing 23:05 Moscow time and arriving 14:00 Vladivostok Time on next day (Flight time is 8 hours).

These typically depart the West Coast between 10 pm and 1 am, have a flight time of 3–6 hours but lose 2–4.5 hours due to the time difference, and arrive between 5 am and 7 am. Red-eye flights also connect Hawaii and Alaska with West Coast mainland cities. Furthermore, red-eyes also connect Honolulu with Tokyo, as the flights only depart at night, and arrive around 6 to 7 hours later.
In the 1930s and 1940s, red-eye flights were not possible, as most airports did not have the equipment necessary to work at night. There are still airports that do not function after certain hours, or have curfews for noise reasons, limiting the number of airports from which red-eye flights can depart.
