Ultimate Guide to Preparing for and Surviving Flights Over 12 Hours

1. Choose the Right Seat for Comfort

When preparing for a flight longer than 12 hours, selecting the right seat can make a major difference. Window seats are ideal for those who want to sleep undisturbed, while aisle seats offer more freedom to move around. If possible, avoid seats near lavatories or galleys, as these areas tend to be busy and noisy. Consider investing in a seat with extra legroom—though it may cost more (often around ¥3,000 to ¥10,000 or $20 to $70), the comfort it brings is worth it during long-haul travel.

2. Pack Smart: Essentials for Long-Haul Flights

Efficient packing is key to surviving a long flight. In your carry-on, include noise-canceling headphones, a neck pillow, an eye mask, earplugs, and a travel blanket. Don’t forget important toiletries like toothbrush, toothpaste, lip balm, and facial wipes. It’s also wise to carry medications and chargers in your hand luggage. Snacks high in protein and low in sugar can help you avoid the highs and crashes of in-flight meals.

3. Dress for the Journey: Comfort Over Fashion

On a long flight, comfort should be your top priority. Choose soft, breathable fabrics like cotton or moisture-wicking materials. Dress in layers to easily adapt to fluctuating cabin temperatures. Compression socks are highly recommended to improve blood circulation and reduce the risk of swelling or deep vein thrombosis (DVT). Comfortable shoes or slippers can also make a big difference when walking around the cabin.

4. Stay Healthy and Hydrated in the Air

Cabin air is extremely dry, which can lead to dehydration and fatigue. Drink water regularly throughout the flight—aim for at least one cup every hour. Avoid alcohol and caffeine as they can further dehydrate you. Stretching and walking every few hours helps maintain circulation and reduce stiffness. Simple in-seat exercises like ankle rolls or shoulder shrugs can also be effective in keeping your body active.

5. Beat Jet Lag: Tips to Adjust Quickly

To minimize jet lag, try adjusting your sleep schedule a few days before departure to match your destination’s time zone. During the flight, avoid sleeping too much if it conflicts with your destination’s day time. Once you arrive, spend time in natural light and stay active during the day. Melatonin supplements can also be helpful to reset your internal clock, but consult a doctor before use. A well-planned routine can significantly reduce recovery time from long-haul flights.

1. Choose the Right Seat for Comfort

Selecting the right seat can significantly impact your comfort during a flight that lasts over 12 hours. A window seat allows you to lean against the wall for rest and minimizes disturbances. On the other hand, an aisle seat gives you easy access to the restroom and freedom to stretch your legs. For added comfort, consider upgrading to seats with extra legroom or premium economy class, which can cost around ¥5,000–¥15,000 (approximately $35–$100), depending on the airline and route. Avoid seats near lavatories or galleys, which can be noisy and have high foot traffic.

2. Pack Smart: Essentials for Long-Haul Flights

Packing the right in-flight essentials can make a world of difference. Bring a neck pillow, eye mask, noise-canceling headphones, and earplugs to help you sleep. Include a small bag with personal hygiene items like facial wipes, toothbrush, toothpaste, hand sanitizer, and lip balm. Keep medications and chargers in your carry-on. Snacks such as nuts, protein bars, or dried fruit are good options to stay energized between meals. A refillable water bottle can help you stay hydrated throughout the flight.

3. Dress for the Journey: Comfort Over Fashion

Long flights are not the time for tight jeans or high heels. Instead, opt for loose-fitting, breathable clothing like cotton or athletic wear. Dressing in layers is a smart move, as cabin temperatures can fluctuate. A lightweight hoodie or cardigan can keep you warm without being bulky. Compression socks, which can cost around ¥1,000–¥3,000 ($7–$20), are highly recommended to improve circulation and reduce swelling. Slip-on shoes are ideal for security checks and mid-flight bathroom trips.

4. Stay Healthy and Hydrated in the Air

Dehydration is common on long flights due to low cabin humidity. Drink plenty of water—experts recommend about 250 ml (1 cup) every hour. Minimize alcohol and caffeine intake as both contribute to dehydration. Move around the cabin every few hours to reduce the risk of blood clots and stiffness. Simple stretches, leg lifts, and ankle rolls can also keep your blood flowing while seated. Bring hand sanitizer and disinfectant wipes to keep your area clean and reduce exposure to germs.

5. Beat Jet Lag: Tips to Adjust Quickly

Jet lag can disrupt your trip, especially when crossing multiple time zones. To ease the transition, begin adjusting your sleep schedule a few days before departure. During the flight, try to align your sleep with the destination’s time zone. Use a sleep mask and noise-canceling headphones to improve rest. Upon arrival, spend time outdoors in natural light to help reset your body clock. If needed, consider taking melatonin supplements (¥500–¥2,000 or $4–$15), but consult a healthcare provider first. Staying active and hydrated also speeds up recovery.

1. Choose the Right Seat for Comfort

For flights longer than 12 hours, the seat you choose can determine how rested you’ll feel when you land. A window seat is ideal for those who plan to sleep, while an aisle seat is better if you need to move around frequently. Avoid seats near restrooms and galleys due to noise and foot traffic. Some airlines offer extra legroom or premium economy options, which typically cost an additional ¥5,000 to ¥15,000 (around $35 to $100). It’s a worthwhile investment for better sleep and overall comfort.

2. Pack Smart: Essentials for Long-Haul Flights

Packing efficiently can greatly enhance your in-flight experience. In your carry-on, include travel-size toiletries such as a toothbrush, toothpaste, facial wipes, and hand sanitizer. Don’t forget sleep aids like a neck pillow, eye mask, earplugs, and noise-canceling headphones. A small blanket or scarf can keep you warm in the chilly cabin. Bring healthy snacks like protein bars, nuts, or dried fruits. Staying organized and having everything within reach will make your journey smoother and more comfortable.

3. Dress for the Journey: Comfort Over Fashion

When flying for more than half a day, comfort should be prioritized over style. Wear loose, breathable clothes made of materials like cotton or bamboo. Layering is essential to adjust to varying cabin temperatures. Compression socks (usually ¥1,000 to ¥3,000 or $7 to $20) can prevent swelling and improve circulation during long periods of sitting. Slip-on shoes or sneakers are ideal for security and comfort. A lightweight jacket or hoodie is useful for both warmth and added coziness during the flight.

4. Stay Healthy and Hydrated in the Air

Staying healthy on a long flight starts with staying hydrated. Drink water regularly—aim for about one cup every hour. Avoid alcohol and caffeine as they can increase dehydration. Move around the cabin every 2–3 hours to keep your blood circulating and reduce the risk of deep vein thrombosis (DVT). Even simple in-seat exercises like stretching your legs or rolling your ankles help. Use disinfectant wipes to clean your tray table, seatbelt, and armrests to reduce exposure to germs.

5. Beat Jet Lag: Tips to Adjust Quickly

Jet lag can hit hard after a long international flight. Start adjusting your sleep schedule a few days before your trip to better align with your destination’s time zone. Try to stay awake or sleep during the flight according to your arrival schedule. Once you land, get outside during daylight hours to help reset your internal clock. Light exercise, staying hydrated, and avoiding naps can help you adapt faster. Some travelers find melatonin supplements (about ¥500–¥2,000 or $4–$15) helpful, but always consult a doctor beforehand.

1. Choose the Right Seat for Comfort

Selecting the right seat is one of the most crucial steps when preparing for a flight that lasts over 12 hours. If you’re someone who prefers uninterrupted sleep, a window seat is your best bet. It gives you something to lean on and avoids the disturbance of other passengers moving past. Aisle seats, on the other hand, are ideal if you plan to move around or use the restroom frequently. Try to avoid seats near restrooms or galleys, as these areas tend to be noisy. For better comfort, consider paying extra for seats with more legroom or premium economy. These upgrades can cost around ¥5,000–¥15,000 (about $35–$100), depending on the airline.

2. Pack Smart: Essentials for Long-Haul Flights

What you bring onboard can greatly affect your flight experience. Essentials include a neck pillow, noise-canceling headphones, an eye mask, and earplugs—all of which help improve sleep quality. Don’t forget personal hygiene items such as hand sanitizer, lip balm, face wipes, and a toothbrush. Bring a power bank and charging cables for your devices. Healthy snacks like granola bars, dried fruits, or mixed nuts will keep your energy up without relying too much on airline food. Lastly, carry a refillable water bottle to stay hydrated throughout the flight.

3. Dress for the Journey: Comfort Over Fashion

When flying for over 12 hours, your outfit should prioritize comfort. Choose soft, breathable fabrics like cotton, bamboo, or moisture-wicking material. Dress in layers so you can easily adjust to fluctuating cabin temperatures. Compression socks, which usually cost between ¥1,000 and ¥3,000 (approximately $7–$20), are helpful for preventing swelling and improving blood circulation. Comfortable, slip-on shoes make bathroom trips and security checks easier. Avoid tight clothing that could restrict movement or circulation during the flight.

4. Stay Healthy and Hydrated in the Air

The dry air in airplane cabins can quickly dehydrate you, especially on longer flights. Aim to drink about 250ml (one cup) of water every hour. Avoid alcohol and caffeine, as they can worsen dehydration. Regular movement is also important. Get up to walk the aisle every few hours, and do light stretches or in-seat exercises like foot circles and shoulder rolls. Clean your hands regularly and disinfect your tray table and armrests to minimize the risk of catching a cold or other illness while traveling.

5. Beat Jet Lag: Tips to Adjust Quickly

Jet lag can disrupt your sleep and energy levels, especially after long flights across time zones. A few days before your trip, start adjusting your sleep schedule to match your destination’s time. During the flight, avoid sleeping if it’s daytime at your destination. Once you arrive, get outside in the sunlight as much as possible to help reset your internal clock. Short walks and light meals can also aid your transition. If necessary, melatonin supplements (around ¥500–¥2,000 or $4–$15) may help regulate sleep, but consult a doctor before using them.

1. Choose the Right Seat for Comfort

A seat can make or break your experience on a flight over 12 hours. If sleep is your priority, go for a window seat so you can rest your head and avoid being disturbed by others needing to move. Aisle seats, meanwhile, offer freedom to stretch and walk without bothering seatmates. Avoid seats close to restrooms or galleys—they tend to be noisier and have more foot traffic. Consider paying for extra legroom or premium economy if available, which can cost around ¥5,000 to ¥15,000 (roughly $35 to $100), but the added comfort is often worth it on long-haul flights.

2. Pack Smart: Essentials for Long-Haul Flights

Being well-prepared is crucial. In your carry-on, pack a neck pillow, eye mask, earplugs, and noise-canceling headphones to help you rest. Bring personal items like a toothbrush, toothpaste, hand sanitizer, face wipes, and lip balm to stay fresh. Don’t forget device chargers and a power bank. Snacks such as protein bars, mixed nuts, or dried fruit are great for staying full between meals. A refillable water bottle will help you stay hydrated without depending solely on the flight attendants.

3. Dress for the Journey: Comfort Over Fashion

Comfortable clothing is essential for long flights. Opt for loose, breathable fabrics like cotton or athletic wear. Dress in layers so you can adjust based on the cabin temperature. Compression socks (¥1,000–¥3,000 or $7–$20) can prevent leg swelling and improve circulation during long periods of sitting. Choose easy-to-remove shoes for both comfort and convenience at airport security. Avoid restrictive clothing that may cause discomfort during the long hours in a seated position.

4. Stay Healthy and Hydrated in the Air

Cabin air is extremely dry, so it’s easy to become dehydrated on long flights. Try to drink 200–250 ml of water every hour. Avoid alcohol and caffeine as they can accelerate dehydration. Move around the cabin regularly and stretch your legs to prevent stiffness and reduce the risk of deep vein thrombosis (DVT). In-seat stretches like ankle rolls, shoulder rotations, and neck tilts can also help. Carry disinfectant wipes to clean your tray table, screen, and seatbelt buckle before use to lower your exposure to germs.

5. Beat Jet Lag: Tips to Adjust Quickly

Jet lag can leave you feeling disoriented for days after your flight. To minimize its effects, start adjusting your sleep schedule a few days before your trip. Try to sleep and eat in sync with your destination’s time zone during the flight. Upon arrival, get exposure to natural sunlight as soon as possible—it’s the most effective way to reset your body clock. Stay hydrated, eat light meals, and avoid long naps. If necessary, melatonin supplements (¥500–¥2,000 or $4–$15) can be helpful, but consult a doctor before use.
