Red-eye flights are normally flights that depart late at night and arrive early in the morning, outside of the common operational day. It is a casual name used to refer to such flight times and the name refers to the eye fatigue that accompanies late night-early morning travel.
In the common usage of the term for Canada and U.S. flights, red-eye flights are those that depart from the west coast to arrive on the east coast. They would leave sometime between 10pm to 1am and arrive 5am to 7am.
