Most people don’t discuss red-eye flights without at least a hint of despair, but frequent flyers know that’s not entirely fair. In fact, there are considerably more pros than cons to booking and flying a red-eye if you understand the proper considerations and make an informed decision. Below, you’ll learn not only what a red-eye flight really is, but also how to determine whether they’re right for you and your specific itinerary, and how to maximise the experience if you do find yourself on one of these much-maligned flights.


What is a red-eye flight?

If you’re looking for a super-specific definition that answers exactly what time a red-eye flight is, you won’t find one. What’s considered a red-eye flight is a fairly loose concept that covers any itinerary departing at night and arriving at the destination in the morning.

So, what does a red-eye flight mean for you if you choose one? It really doesn’t mean anything more than that you’ll be flying overnight.

If you, like most people, typically sleep during this time, it’s worth considering whether you historically sleep well on planes before booking a red-eye; if you fail to get a good bit of rest on board, you may arrive with tired, red eyes that give this flight its negative name.

What are the pros of a red-eye flight?

Despite the bad reputation they seem to have, the benefits of a red-eye flight can be numerous. They’re typically cheaper than daytime flights and they allow you to arrive at your destination at the beginning of a new day, but there are airport and aeroplane benefits, too. Because fewer people fly during these times, airports are less crowded, which means both check-in lines and security lines are often dramatically shorter. It’s also easier to make your way to the gate with fewer people clogging the terminals.

The planes themselves are less likely to be full, too, which means you may score an empty neighbouring seat, or even an entirely empty row which is not only more comfortable but can help you sleep better. Fewer people also means less potential for ambient noise and commotion that can otherwise make sleep more difficult, too. You may even benefit from less traffic on the way to the airport.

What are the cons of a red-eye flight?

The cons of red-eye flights are few, but significant for those they affect. Primarily, those who don’t sleep well on planes are not likely to have a great flight experience when flying when they would normally be sleeping, and will likely arrive groggy. This can also lead to more severe effects of jet lag.

Secondarily, if you’ll be staying at a hotel with an afternoon check-in, arriving early in the morning with all of your luggage may not be a bonus. You can often drop your bags at the hotel early and explore the area while you wait for your room, but you may not be able to shower and freshen up from your overnight flight first.

If you decide that red-eye isn’t for you, uncheck “Show red-eyes” under the flight quality menu on the left side of the results page when searching for flights on KAYAK and you’ll never risk booking one unintentionally.

How to prepare for a red-eye flight

Red-eye or not, there are several tips for flying that will improve your experience on any flight, so check those out first. When preparing for your red-eye, though, there are a few considerations that are even more important than usual, and these revolve around sleep.

Book a window seat so you’re not woken up whenever someone in your row needs to use the restroom; wear loose-fitting clothes to maximise comfort; and avoid caffeine and excess alcohol before and during the flight. Perhaps most importantly, avoid connecting flights whenever possible so you aren’t woken up to change planes and face another airport in the middle of your rest.

5 tips for surviving a red-eye flight

You read all about the pros and cons of a red-eye flight and what exactly it is, so here you have 5 tips on how to survive a red-eye flight.

1. Don’t dread the flight

This may be easier said than done, but dreading the flight only increases the stress and anxiety that will make your journey less comfortable and may prevent you from falling asleep onboard, so don’t fixate on the fact that you’re taking a red-eye. Keep in mind that there’s nothing inherently bad about a red-eye flight, and treat it like any other evening so you don’t introduce unnecessary stress to your mind and body.

2. Wear compression socks

Compression socks can help reduce the risk of blood clots during long, overnight flights by helping maintain healthy blood flow, but even those with less serious health concerns can benefit from wearing a pair. I like to wear compression socks on any long flight to prevent swelling (which can take days to go down) and to help keep my legs more comfortable while stuck in the same position all night when my legs would typically be level with my body in bed.

3. Don’t bring electronic entertainment

What do you do on red-eye flights? Sleep. That’s the goal, at least, so don’t bring a plethora of screens that can keep you awake longer with excessive blue light exposure. They also dry out your eyes by reducing blinking, and the plane cabin is dry enough as it is. You’re trying to avoid arriving with red eyes, not guaranteeing it. Further, everyone else on the plane wants to sleep, too, so try not to light up your row with your bright devices. If you can’t sleep, don’t stress. Instead, consider some of the quieter, calmer things to do on a plane to pass the time comfortably.

4. Cover your eyes and ears

Light and sound will be your biggest obstacles to falling asleep and staying asleep on an overnight flight, so come prepared with an eye mask and something for your ears. If you can sleep comfortably with large headphones, opt for a set with noise-cancelling capability. Otherwise, play some classical music through smaller headphones or earbuds to distract from surrounding sounds. If you prefer silence, pack earplugs.

✈️ Pro Tip: For your eyes, a silk mask is the coolest material that won’t pull at your face or hair, and also minimises negative effects on your skin.

5. Settle in for the long haul

Red-eye flights are designed for longer routes, so prepare to be in a confined space for a considerable duration. Getting tips for long flights is a great starting point for preparing for a more comfortable red-eye experience, but remember that sleep is your number one goal for this particular long flight, so focus on those tips that will bring you the most physical comfort, personally.

✈️ Pro Tip: Some say travel pillows are a waste of cabin bag space, but I always bring two: one for my neck and one for an elbow or for my seat—wherever I need it more in the moment. Adapt all tips to your own body and needs.

How this guide was created

I’m on aeroplanes at least twice a week, every week, averaging 120 flights per year. Because I often fly cross-country or internationally, many of those flights are red-eyes, so I’m quite used to the long, overnight trips that people tend to love or hate (personally, I love them). I’ve combined years of this experience with KAYAK’s expert tips and tools to create this guide.

Red-eye flights FAQ

Are red-eye flights cheaper?

Usually. Flight prices are driven by demand, and people prefer to fly during daytime hours, so red-eyes are almost always less expensive. The cheaper price is an airline incentive to get more people onboard these off-hours flights and free up demand during the day. Of course, if a specific route only has red-eye options, you likely won’t notice much in terms of savings.

How safe are red-eye flights?

From a crew and equipment perspective, red-eye flights are as safe as any other flight. There are some potential risks to your personal health if you fly them often, though, particularly if you don’t sleep well on planes. Frequent red-eyes for poor sleepers can lead to health concerns like higher blood pressure and weight gain, but there’s a risk for good sleepers, too. Blood clots are more likely during red-eyes because they’re often longer flights that combine a low-pressure environment with little movement in a good sleeper.
