Red-Eye Flight
An overnight flight that departs late at night and arrives early in the morning — named after the tired, red eyes of passengers who sleep badly on planes.
What is a red-eye flight?
A red-eye flight is any flight that departs late in the evening (typically after 9pm) and arrives early in the morning (typically before 6am). The name comes from the bloodshot, red eyes that passengers typically arrive with after a night of broken sleep in an aircraft seat. Red-eyes are most common on transatlantic routes (London to New York, Lisbon to Brazil) and transcontinental US routes.
On short-haul European routes, the equivalent is often called a "dawn departure" — a flight departing between 5am and 7am. Ryanair and easyJet built much of their low-cost model around these slots, which are cheaper for airlines to use and less convenient for passengers.
Why red-eyes are good value
Red-eye flights are consistently cheaper than daytime equivalents on the same route. Airlines need to fill these flights, and passengers who can tolerate the disruption to their sleep schedule are rewarded with significantly lower fares. On transatlantic routes, a red-eye can cost 30–50% less than the equivalent daytime business offering.
From a practical standpoint, a red-eye saves you a night's hotel cost. Fly overnight, arrive in the morning, and you have the full day ahead without losing time or money on accommodation. Business travellers on tight budgets — and travellers who can sleep on planes — use red-eyes routinely.
Making a red-eye work
Choose an aisle seat if you need to move around, or a window seat if you want to lean against the side and avoid disturbances. Bring an eye mask, ear plugs or noise-cancelling headphones, and a travel pillow. Avoid alcohol, which dehydrates you and disrupts sleep quality. A light meal before departure and no screens for an hour before the lights go down will help you settle faster.
On arrival, resist the urge to nap for long. A 20-minute rest and a strong coffee will help you reset your clock faster than a 3-hour crash that leaves you groggier than before.
