Red-eye flight

An EgyptAir Boeing 787 prepares for a red-eye flight from London Heathrow to Cairo

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.[1]
