Red-eye flight

In commercial aviation, a red-eye flight refers to a flight that departs at night and arrives the next morning, especially when the total flight time is insufficient for passengers to get a full night's sleep.
The term derives from red eyes as a symptom of fatigue.
For the airline, overnight flights enable more use of aircraft that would otherwise stand idle. For airports, it may be rational to divert the stream of passengers away from peak hours. In major airports, the capacity for flight operations during daytime may be fully exhausted, and the price of airport slots may be higher at peak hours.
For passengers, the benefits and disadvantages are more subjective. While overnight flights are often less costly, many will perceive it difficult to arrive well-rested after a night flight, especially if it is at odd hours or too short to fit into a full night's sleep. However, the traffic to and from the airport, as well as the airport experience, may be less stressful at these hours. Some passengers may want to arrive early in a city and return the same day, saving on a night's accommodation, or enjoy one full day at the beginning or end of the trip. It has been claimed that red-eye flights are popular among business travelers who benefit from flying at night. Business class seats are often reclinable to a flat position, enabling normal sleep.
One definition of a red-eye flight is one that is too short to allow a full night's sleep. An example would be those flights from Los Angeles to New York City—about five hours' flying time—that depart between 2100 and 0100 Pacific time, and arrive between 0500 and 0900 Eastern time.
From Taipei to the west coast of the US, EVA Air flies red eyes leaving at 10 am or 10 pm and arriving at 7 am or 7 pm the same day.
The majority of transcontinental flights are operated during the day, but as of 2010, red-eye flights operate from Perth to Sydney, Brisbane, Cairns, Canberra and Melbourne, and from Darwin to Sydney, Brisbane and Melbourne. Red-eye flights have previously operated from Australia to New Zealand and Fiji.
Red-eye flights to Australia operate from various locations in Southeast Asia and North America, such as Scoot's flights from Singapore to Gold Coast, Sydney, and Melbourne. Jetstar offers red-eye flights between Melbourne and Wellington with the flight departing Melbourne at 1 am and arriving in Wellington at 6 am.
Another example would be Qantas flights from Los Angeles to Brisbane, Sydney and Melbourne, and from Dallas to Sydney) generally leaving 10 pm to 11 pm and arriving from 5 am to 8 am. While they do fly during the night (this is more a product of large time zone differences) the flights take around 15 hours (giving more time to sleep) and westward flight stretches out the local length of day and night. Furthermore, as the flight crosses the International Date Line, flights arrive roughly two days later in local time.
LATAM Brasil, Azul Brazilian Airlines and Gol Transportes Aéreos all offer red-eye flights in Brazil, popularly known as "Big Owl," after a late-night film session broadcast by Rede Globo (Portuguese: Corujão), with over 50 different routes throughout Brazil, all departing between 10 pm and 6 am. Usually these flights originate in Brasília, Belo Horizonte, Campinas, Rio de Janeiro, Salvador, or São Paulo and are bound for Manaus, Belém, Porto Velho, Northeast Brazil, North America, Argentina, and Europe.
Another example is Copa Airlines, which operates several red-eye flights to Argentina, Chile, Bolivia, and several other destinations within Latin America.
Red-eye flights to Europe were once meant to apply exclusively to the morning arrivals of transatlantic flights from the American East Coast to Western Europe. Such traffic now comprises the busiest of the long-haul air routes. The first of these flights, from the busiest destinations of New York and Washington D.C., will arrive at the major European airports at London Heathrow, Frankfurt, Amsterdam, Paris, and Dublin between 0500 and 1200 local time (and when still subject to costly night-flying restrictions); and hence in increasing numbers and to and from a wide range of American/European destinations.
Travelling from Europe, red-eye flights are scheduled out of Madrid, Barcelona, Paris, and Frankfurt. The flight time is of three to five hours, with typical departure around midnight, and arrival around dawn the next day. Most airlines from the Middle East and Asia operate red-eye services from major Western European destinations. One example is London Heathrow, where the last departures - leaving between 22.30 and 23.00 - are eastbound medium-haul services to destinations such as Tel Aviv. Also, long-haul services depart Europe and arrive in Asia at practically the same time the next day (For example, leaving London at 2 pm and arriving at Hong Kong at 12 pm the next day.)
Russian airlines operate similarly to U.S. airlines by connecting Moscow to Yakutsk, Irkutsk, and Vladivostok. They last five to eight hours but due to the northerly latitude the flights can cross as many as eight 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 11:05 pm Moscow time and arriving 2:00 pm Vladivostok Time on the next day, with a flight time of approximately eight hours.
Many medium and long-haul flights to/from South Africa and Europe, other African destinations and the Middle East make use of red-eye flights and longitudinal advantages (similar time zones) so that passengers can arrive at their destinations early in the morning and benefit from minimal time zone changes due to South Africa's geographic position. This makes it an efficient and convenient way to travel between each area.
Red-eye flights frequently connect West Coast cities to East Coast cities. These typically depart the West Coast between 9 pm and 1 am, and have a flight time of three to six hours but gain between two and four hours due to the time difference, arriving on the East Coast between 5 am and 9 am. American Airlines, United Airlines, Delta Air Lines, Alaska Airlines, Air Canada, JetBlue, and other U.S. and Canadian carriers operate red-eye flights that depart from the West Coast at night from cities such as Los Angeles, Vancouver, Calgary, San Francisco, and Seattle, among others, arriving in Boston, New York, Toronto, Washington, D.C., and other East Coast cities in the morning. Red-eye flights also connect Hawaii or Alaska with West Coast mainland cities, departing from Honolulu between 10pm and midnight or Anchorage between midnight and 3 am and arriving in Los Angeles, San Francisco, or Seattle between 5 am and 7 am. Flights from Tokyo to Honolulu are considered red-eye flights, as the flights are usually overnight flights that are six to seven hours.
From the conterminous US, there are flights departing between midnight and 2 am, headed towards East Asian destinations such as Japan, Korea, Taiwan, China, and Hong Kong and arriving between 5am and 7am.
Films involving red-eye flights include Airport 1975 (1974), Airplane! (1980), The Langoliers (1995), Turbulence (1997), Red Eye (2005), Snakes on a Plane (2006), and Non-Stop (2014).
The 2020 TV series Into the Night includes a red-eye flight in its central premise.
