Long Haul Flight Essentials UK 2026, 20 Things You Actually Need (and 6 You Don't)
The right long-haul flight essentials are the ones that solve three real problems: sleep, hydration, and circulation. Get those three right and you land like a human. Get them wrong and you spend day one of your trip horizontal, wondering why you bothered. We've done a lot of long-haul, Bali, Bangkok, Costa Rica, and we've learned through painful trial and error what actually matters. These are the 20 things we pack every single time, plus the 6 things everyone recommends that we quietly leave at home.

The 20 essentials
GO PAC Comfort Sleep PAC GO PAC Kit
The Comfort Sleep PAC is where we start because it solves three problems in one box: the Trtl Pillow Plus (see pick 2), a contoured sleep mask, and foam earplugs, all folded together and ready to go. If you're new to long-haul or you've been getting by with a rolled-up jumper, this is the upgrade that makes the biggest difference for the least effort. Everything's been tested by us first. No filler.
View the Sleep PAC ✦Trtl Pillow Plus Top Pick
The Trtl is not a U-pillow. It's a scarf-style neck support that wraps around and holds your head sideways, which is actually how most people sleep on planes. We've tested it on flights from London to Bali (14+ hours) and Bangkok (12 hours). If you're a sideways or window-leaner, it's genuinely better than anything inflatable we've tried. Not for everyone: upright sleepers won't benefit. But for the majority, it's worth every penny. Read our full Trtl review.
Amazon UK ↗Manta Sleep Mask Top Pick
Total blackout matters more than almost any other sleep variable. The Manta does this with adjustable eye cups that sit over your eyelids rather than pressing on them, so you can blink, open your eyes underneath, and not wake up with mascara distributed across your cheekbones. Adjustable strap fits over earbuds too. If you've only ever used a thin airline mask, this will be a revelation. Light leaks are sleep killers; the Manta kills them back.
Manta Sleep ↗Anker Soundcore Sleep A20
Specifically designed to be worn while lying down, flat profile, ear-tip design, no protruding nubs to dig into your ear against a headrest. They're not noise-cancelling in the Bose/Sony sense, but they play white noise or block ambient sound well enough to sleep through cabin announcements and the person behind you. Battery life is excellent. If you're already sleeping with your regular AirPods and wondering why they hurt after an hour, this is why.
Amazon UK ↗Bose QuietComfort Ultra Earbuds Premium
If you're doing long-haul regularly and you're not using noise-cancellation yet, this is the single upgrade that will change how you travel. Not cheap. But the difference between listening to cabin noise for 12 hours and not listening to it is the difference between arriving tired and arriving wrecked. The Bose QC Ultra are class-leading. Worth considering the Bose QC45 headphones if you prefer over-ear and want to save £100.
Amazon UK ↗GO PAC Travel Tech PAC GO PAC Kit
Cables, adapters, a power bank, and a cable organiser, all in one neat box. We built this because we got fed up watching people at departure gates with cables in a knot, three separate bags for chargers, and a power bank that died somewhere over the Bay of Biscay. The Travel Tech PAC keeps everything together so you board with one less thing to think about. Built for long-haul; useful everywhere.
View the Tech PAC ✦Anker 737 Power Bank (26,800mAh)
140W total output, charges your laptop as well as your phone, and holds enough to fully charge most devices three or four times over. This is the power bank you want if you're working on the flight, or if you've got a 14-hour Bali run and genuinely need everything to last. Heavier than pocket power banks but worth it for serious long-haul. Check current airline battery restrictions before flying, 100Wh limit applies to most carriers.
Amazon UK ↗Skross World Travel Adapter
One adapter. Every socket type. USB-A and USB-C ports built in. This is the one we actually travel with, not because it's the cheapest (it isn't) but because the build quality means it doesn't develop a rattle on day three or fall apart at a wall socket. Covers Europe, US, Australia, and Asia. The kind of thing you buy once and carry for years.
Amazon UK ↗Compression Travel Socks Health Essential
Non-negotiable on any flight over 6 hours. Reduced circulation in your legs during long periods of sitting leads to swelling, discomfort, and a raised (if small) DVT risk. Compression socks keep blood moving without requiring you to get up every hour. Look for 15–20 mmHg medical-grade compression rather than generic travel socks, which are typically too light to do much. Put them on before boarding. Your ankles will be normal-sized when you land.
Amazon UK ↗Refillable 100ml Travel Bottles
Decant your cleanser, moisturiser, and shampoo before you fly rather than buying travel-sized versions at 3x the per-ml cost. A good set of silicone squeeze bottles with labelling stickers costs less than a single travel-sized moisturiser and works indefinitely. Pack them in a clear zip bag in your personal item for security. Use the space and money you save on something useful.
Amazon UK ↗Burt's Bees Lip Balm
Cabin air is drier than most deserts, literally. Aircraft cabins run at around 10–20% humidity, compared to the 30–60% you'd find at sea level. Your lips crack, your throat dries out, your skin tightens. A good lip balm is not a luxury item on a long-haul flight. It's maintenance. Burt's Bees because it's beeswax-based and actually works; most petroleum-jelly balms create a temporary seal without genuinely moisturising. One in your pocket, not buried in your bag.
Amazon UK ↗Avène Thermal Spring Water Spray
A face mist sounds frivolous. It isn't. Spritz it on during the flight when your skin starts feeling tight, which it will, a few hours in, and it genuinely helps. Avène's formulation is soothing rather than just water, which matters if you have sensitive skin. Small enough to fit in your seat pocket. Looks slightly odd to use mid-flight and we do not care.
Amazon UK ↗L'Occitane Shea Butter Hand Cream
Same logic as the lip balm. Your hands take a lot of punishment in dry cabin air and from all the sanitising gel you've been applying at security. A 30ml tube fits within liquids limits and lasts multiple long-haul trips. The L'Occitane Shea is thick, absorbs properly, and doesn't leave your hands greasy, which matters when you're trying to use a touchscreen. The smell is calming too, which is a small psychological bonus on hour nine.
Amazon UK ↗Que Collapsible Water Bottle
Empty through security, full from the airside fountain. The Que collapses down to almost nothing when empty, so it takes up no real space in your bag. Once past security it's a free unlimited water source for the rest of the journey. Being dehydrated on a long-haul flight affects everything, sleep quality, how you feel on landing, headache likelihood. Drink more than you think you need. This bottle makes that effortless.
Amazon UK ↗GO PAC Essential Travel PAC GO PAC Kit
Our flagship kit, the one that goes on every flight regardless of the destination. It's built around the essentials: a curated selection of travel-ready gear that we've tested ourselves and hand-fold together. If you're kitting out for long-haul and want to start with one decision rather than twenty, this is where to start. Everything in it earns its weight.
View the Essential PAC ✦Better You Magnesium Sleep Spray
Magnesium helps muscles relax and supports sleep onset without the grogginess you get from antihistamine-based sleep aids. The spray format means you're absorbing it transdermally rather than swallowing a pill, which some people find easier mid-flight. Apply to your legs or arms about 20 minutes before you want to sleep. It won't knock you out, but it takes the edge off that "I'm exhausted but can't switch off" feeling. Safe to use with melatonin if you're using both.
Amazon UK ↗Hycosan Eye Drops
Preservative-free lubricating drops. If you wear contact lenses on long-haul flights, these are essential, dry cabin air desiccates contacts within a few hours. Even without lenses, tired, irritated eyes are a common side effect of long-haul. A few drops make a meaningful difference to how you feel during and after. Small enough to go in your seat pocket alongside your lip balm. Worth the space.
Amazon UK ↗A Pen (Specifically the Fisher Space Pen)
This sounds absurd, but hear us out. Arrival cards still exist on international flights. The airline will not have a pen. The person next to you will not have a pen. You will be filling out a customs declaration on your knee with a ballpoint that belongs to someone four rows back. The Fisher Space Pen writes in any orientation, at any temperature, and doesn't leak in your bag at altitude. Buy it once; carry it forever. Genuinely one of the most-used items we own.
Amazon UK ↗Eagle Creek Compression Packing Cube (Small)
Keep a fresh change of clothes in your carry-on, compressed to near nothing in a small cube. This one habit transforms how you handle delays, connections, and the indignity of whatever happened between boarding and landing. One shirt, fresh underwear, and a clean face combined with your onboard skincare routine is the closest you'll get to arriving fresh. Don't check your only change of clothes. Delays happen.
Amazon UK ↗Kindle Paperwhite
The e-ink Paperwhite has a battery that lasts weeks, not hours. Your phone battery does not. On a 14-hour overnight flight where you want to sleep but can't quite manage it, having something to read that isn't your phone screen matters, phone screens suppress melatonin; the Paperwhite's front light doesn't do the same damage. Stores hundreds of books. Weighs next to nothing. Has no social media. This is not a sponsored mention. We just use it.
Amazon UK ↗6 things we'd skip
The internet is full of long-haul packing lists that recommend these. We disagree. Politely, but firmly.
- Inflatable U-pillows, they position your head too far forward and your chin ends up on your chest. You wake up with a stiff neck. The whole point of a travel pillow is to prevent this. Spend £10 more and get the Trtl instead.
- Single-purpose portable fans, your phone already controls the air vent above your seat. The overhead vents on modern aircraft are genuinely powerful. A portable fan is one more thing to charge and one more thing to lose.
- Disposable in-flight slippers, your socks are fine. The ones provided by premium cabin airlines are an exception; budget carrier freebies fall apart on contact with carpet. Just wear your socks.
- Inflatable foot rests, the bladder mechanism on these fails within three uses, they're difficult to inflate quietly without disturbing your row, and the seat pocket depth on most aircraft means they don't reach the floor at a useful height anyway. Economy reality.
- Luxury sleep sprays, lavender pillow mist and branded "calm" sprays are largely scented water. If you want a familiar smell to help you sleep (and this can genuinely help), spray your own perfume on the inside of a sleeve before you board. Costs nothing. Works the same.
- Products labelled "TSA-approved", this isn't a product category; it's marketing. A product being TSA-approved simply means it meets standard liquids restrictions. It tells you nothing about quality. The label is used to charge 30–50% more for ordinary travel bottles, locks, and bags. Ignore it.
How to actually sleep on a plane
The gear helps, but the strategy matters more. Here's what we've learned after a lot of overnight flights:
Recline the moment the belt sign goes off. Don't wait. The passenger in front of you will recline into your space; you're entitled to do the same. If you're polite about it and recline gradually, it rarely causes conflict.
Hydrate aggressively before boarding. Not alcohol, water. Proper hydration before you board means you arrive in better shape and sleep better mid-flight. Alcohol dehydrates you, disrupts REM sleep, and makes jet lag worse. One drink is fine. Three is not your friend at 35,000 feet.
Block out both light and sound completely. Half measures don't work. The airline mask lets in light at the edges. Earphones with no active noise cancellation let cabin noise through. The combination of total darkness and significant sound reduction is what allows your brain to actually sleep, not just rest.
Try low-dose melatonin (0.5mg, not 5mg). Most supplements sold in the UK come in 1–5mg doses, which is much higher than needed. The physiological effective dose for sleep onset is closer to 0.5mg. Higher doses don't work better, they just give you a pharmaceutical hangover. Available from health food shops or online. Take it about 30 minutes before your intended sleep time, adjusted to destination timezone.
Bring something familiar. Slip your own pillowcase over the airline pillow. Spray a small amount of your usual perfume or cologne on the inside of your sleeve. Your brain makes associations between smells and safety, familiar scents genuinely help your nervous system decide it's okay to switch off in an unfamiliar environment. Try it once; it works more than you'd expect.
Frequently asked questions
What should I pack in my carry-on for a long haul flight?
Focus on the three problems: sleep, hydration, and circulation. That means a travel pillow you'll actually use (the Trtl Plus or our Comfort Sleep PAC), a proper sleep mask, earplugs or noise-cancelling earbuds, a reusable water bottle to fill after security, and compression socks. Everything else is optional. If you only have a small bag, these five things will do more for how you arrive than any amount of snacks or in-seat entertainment.
How do I actually sleep on a long haul flight?
Recline your seat the moment the seatbelt sign goes off, before the person behind you and the seat in front of you both do it. Drink water aggressively before boarding and during the first hour. Block both light and sound completely, this is why a proper sleep mask and decent earbuds matter more than people expect. Low-dose melatonin (0.5mg, taken 30 minutes before you want to sleep, adjusted to destination time) helps without the grogginess. Keep something familiar nearby, your own pillowcase, or a familiar scent on your sleeve. It sounds odd but it genuinely helps your brain decide it's safe to switch off.
Are compression socks worth it for flying?
Yes, especially on flights over 6 hours. Reduced blood flow in your legs during long periods of sitting causes swelling and raises the (small but real) risk of DVT. Look for 15–20 mmHg medical-grade compression rather than generic travel socks, which tend to be too light to do much. You can put them on before boarding and wear them until you clear customs. Your ankles will be normal-sized when you land; that's not always guaranteed without them.
Should I take sleeping pills on a long haul flight?
We'd be cautious. Prescription sleeping pills can cause deep, unnatural sleep that prevents you from moving around, which increases DVT risk. Antihistamine-based options like Nytol are milder but leave many people groggy for hours after landing. Our preference is low-dose melatonin (0.5mg to 1mg) for rhythm-resetting without side effects, combined with the basics: proper darkness, no alcohol, a reclining seat, and a travel pillow that actually works. If you do use sleep aids, get up and walk the aisle at least once mid-flight regardless.
What's the best travel pillow for long haul flights?
The Trtl Pillow Plus is our top pick for most people. It wraps around your neck and provides sideways head support without the bulk of a U-pillow, and sideways is actually how most people sleep. Not for everyone: bolt-upright sleepers won't benefit much. But for window-leaners and sideways-nodders (which is most of us), it's noticeably better than anything inflatable we've tried. Our GO PAC Comfort Sleep PAC bundles it with a sleep mask and earplugs. Read our full Trtl Pillow review for a detailed breakdown.
How can I avoid jet lag after a long haul flight?
Start shifting before you fly: if you're heading east, go to bed an hour earlier for two or three nights beforehand. On the plane, set your watch to destination time immediately and eat and sleep on that schedule, not your departure city's. When you land, get outside into natural daylight as soon as possible, this is the most powerful circadian reset signal your body has. Avoid napping if it's daytime at your destination. Melatonin in the right direction (morning for westbound, evening for eastbound) can shorten adjustment by a day or two. Stay well-hydrated throughout; dehydration makes everything worse.
