<P> 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 . The red - eye flight usually flies eastbound . The flight is usually four to six hours , less than a seven - hour full sleep , but due to time differences and prevailing jet stream winds from the west , a red - eye flight that departs around midnight arrives around 6 am or 7 am . Westbound flights that depart around midnight and arrive in the early morning are also colloquially called red - eye flights , despite the fact that those flights are significantly longer than seven or eight hours . </P>
