The short answer: the one item that changed long-haul flying for me is a forward-lean inflatable pillow, the kind you rest your head and arms on while leaning forward onto the tray table. On a very long flight, being able to rest forward is a game changer. After that, a power bank that is legal on every airline, a plug adaptor with USB ports, and a few comfort items do the rest.
1. A Forward-Lean Travel Pillow (My Top Pick)
Classic U-shaped neck pillows never really worked for me. Your head still drops forward the moment you fall asleep. A forward-lean inflatable pillow takes the opposite approach: you lean into it on the tray table, with an opening for your face so you can breathe freely and space for your arms. Being able to lean forward and rest during a very long flight is a game changer. Deflated, it folds down to almost nothing in your carry-on.
2. A Power Bank That Every Airline Allows
A 20,000 mAh power bank is the practical maximum for flying, and it is allowed on every major airline. The rules are set in watt-hours (Wh), not mAh: 20,000 mAh at 3.7 V works out to about 74 Wh, comfortably under the 100 Wh limit that applies worldwide. Batteries between 100 and 160 Wh need airline approval, and anything above 160 Wh is not allowed at all.
What changed recently is how you can carry and use them. The rules to follow in 2026:
- Power banks go in your carry-on only, never in checked luggage.
- Most airlines allow a maximum of two per passenger; Emirates allows only one.
- A growing number of airlines ban using or charging a power bank during the flight, so charge your devices before you board.
- Buy one with the capacity printed clearly on the case. Unlabelled batteries can be confiscated at security, and China additionally requires the 3C mark for flights within the country.
Airline rules keep changing, so check your airline’s page before you fly.
3. A Plug Adaptor with USB Ports
I travel with an international plug adaptor with USB ports so I can charge several gadgets at the same time from one socket: phone, headphones, power bank and camera. In a hotel room with one free socket by the bed after a long flight, it is the difference between everything charged by morning and choosing which device goes flat.
4. Noise-Cancelling Headphones
Engine noise is tiring even when you don’t notice it. Good noise-cancelling headphones are one of the best comfort upgrades for long flights.
- Bose QuietComfort Ultra Headphones (2nd Gen), widely rated among the strongest noise cancellation for flying.
- Sony WH-1000XM6, the best all-rounder, which fold into a compact case.
- Twelve South AirFly, a small adaptor that lets you use wireless headphones with the seat-back screen.
5. Sleep and Comfort
- A silk eye mask: softer on the skin than airline masks, and it blocks out cabin light.
- Compression socks (15–20 mmHg) for flights over six hours, to reduce swelling in your feet and ankles.
6. Skin
Cabin air is very dry. A few travel-size products make a real difference on arrival:
- Avène Thermal Spring Water in a travel size, a face mist for mid-flight.
- Aesop Departure travel kit, a set of in-flight essentials that fits in a seat pocket.
7. Organisation
- Packing cubes to keep the carry-on in order.
- Apple AirTag in each checked bag, so you know where your luggage is before the airline does.

What is the best pillow for sleeping on a long-haul flight?
For me, a forward-lean inflatable pillow that lets you rest your head and arms forward on the tray table is far better than a U-shaped neck pillow. Being able to rest forward on a very long flight is a game changer.
