Whether you’re taking a seven-hour trip across the pond to Europe or embarking on the nearly 19-hour odyssey from New York City to Singapore, a long-haul flight can be tedious and exhausting. The nuisances of time-consuming air travel can range in severity from mildly inconvenient (annoying seatmates, for instance) to downright dangerous (developing a blood clot on a plane is no joke). To make a big journey more bearable, try to maintain your typical routine, stay hydrated, wear loose clothing, and pack an extra snack or two.

Here are 32 (the balance posted tomorrow) of our favorite tips to make long flights as trouble-free and comfortable as possible.

Book your flight early to secure a good seat.

The earlier you book, the better your chances of securing your favorite seat, whether it’s by the window to enjoy the scenery or at the aisle for easy access to the lavatory. However, please note that airlines may change your seat without prior notice.

Consider a seat in the back of the plane.

Your favorite seat probably isn’t in the back of the plane. It isn’t quiet back there, tends to have little leg room, and means you’re the last off the plane when it lands. However, there are perks to choosing a back seat. If you’re flying with an airline like Southwest that doesn’t have assigned seats, you might have better luck claiming a row to yourself or at least an empty seat next to you in the back. Additionally, being in the back allows you to observe which rows don’t fill up ahead of you, so you can claim one of the emptier ones after everyone has taken their seat.

Use airline miles to upgrade.

You’ll thank yourself when you’re sipping Champagne while reclining in first class after using miles to upgrade your seat. And if you don’t have the miles, this might be the time to splurge for a superior first- or business-class seat. Even upgrading to premium economy will give you priority check-in, extra legroom, and comfortable seats.

Or an angle for a free upgrade.

Arrive early, dress nicely, travel alone, and put on your most winning smile for the best chance at success. Your odds of scoring a last-minute upgrade are better if you have elite status with the airline. Try to carefully time when you ask for a flight upgrade to increase your odds as well.

Adjust your sleep pattern before your flight to ensure optimal rest.

In the days leading up to your flight, adjust your sleep patterns; a few 4 a.m. or 7 p.m. bedtimes should suffice, depending on the time of day you’ll be flying. If your flight is during the day, be well-rested before you fly. If it’s a red-eye, arrive at the airport tired. Trust us on this, though: staying awake for 24 hours before your trip to balance out jet lag doesn’t work.

Dress comfortably.

Keep it loose and comfortable, and remember to bring layers for when the temperature drops. A cardigan or zip-up sweatshirt is always a good option to have on hand, as you can easily put it on or take it off depending on the cabin temperature. Clothes with a bit of stretch, like men’s sweatpants or women’s leggings, can also help you move around more comfortably.

De-stress before you board.

You don’t want to spend your whole flight buzzing about all the things you have to do or what you might have forgotten. Carve out some time before your trip to sit down with a nice breakfast. Go to the gym. Read a book. Go for a walk. It’s important to relax before it’s time to fly.

Check in early.

The worst start to a long-haul journey is to panic your way through a busy airport, arriving at the gate sweaty and frazzled — or even to miss your flight. Plan to arrive at the airport with plenty of time to check your bags and proceed through security.

Don’t overpack your items.

You’ll need more for a long-haul flight than you would for a short one, but that doesn’t mean it’s a good idea to overfill your bag with unnecessary extras. Keep only the essentials in your item so they’re always easy to find and within reach.

Bring your pillow.

A travel pillow is a staple carry-on item for long-distance travelers. Almost every airport sells them, and looking a little ridiculous with one around your neck is a small price to pay for arriving at your destination without a crick in your neck. Please pay attention to your airline’s restrictions to ensure it doesn’t have to be packed inside your item.

Wear noise-canceling headphones.

Noise-canceling headphones help block out annoying airplane noise and loud passengers, allowing you to zone out with a riveting podcast or a favorite playlist. If you don’t have headphones, a pair of good old-fashioned earplugs will also help.

Buckle your seat belt over your blanket.

If you plan to sleep with a blanket during your flight, ensure your buckled seatbelt is still visible. In the event of turbulence, the seatbelt light will activate, and flight attendants may circulate throughout the cabin to ensure that everyone is properly buckled up. If they can’t see your seat belt, they will wake you up. For safety reasons and to avoid “airplane ear,” don’t sleep through takeoff or landing.

Pack an eye mask.

An eye mask is beneficial if you’re flying during the day, or if you want to catch some shut-eye before the cabin lights are dimmed. It’s often an airline freebie in basic amenity kits on international flights, even in economy, but typically not on longer domestic flights.

Try to relax.

Do whatever it takes — meditate, listen to calming music, or practice some breathing exercises. Not only will it help you sleep more easily, but it’s also good for your psyche, especially if flying makes you nervous.

Bring a travel blanket, not a regular blanket.

Please don’t bring anything too thick (remember, it must fit in your carry-on), but ensure your travel blanket is sufficient to keep you warm when the plane’s air conditioning is at full blast.

Download movies onto your tablet or laptop for backup.

In-flight entertainment systems are not always reliable. They sometimes fail, and when they do, you’ll be glad to have something to do, watch, or listen to in reserve.”

One vital tip for travel, especially for seniors, is to wear compression stockings on your long-haul flight to reduce the risk of blood clots. You can purchase these at a low cost through this link. I bought and wear them, not only on long flights but at other times when I know I will be sitting for extended periods.

Typically, flights from the US to South Africa last for 24-40 hours, most of which is spent sitting. It’s essential to get up and walk around the plane (when there is no turbulence) to diminish the risk of blood clots, stiff joints, and painful backs and hips.

We will continue this list in tomorrow’s post with more suggestions. Please check back for more.

Be well.
