How to Prepare for a Long-Haul Flight to Sydney
24 July 2025
A trip from London to Sydney averages a hefty 24 hours with a stopover. No matter if you're a seasoned traveller or taking your first long-haul flight, it’s an incredible journey that requires some planning and preparation to help guarantee a comfortable flight and a smooth arrival.
One of the best ways to ease the discomfort of such a long journey is by choosing to fly Business Class from London to Sydney. The benefits are countless, with the biggest being the ability to enjoy a more relaxed and comfortable experience, from the moment you check in to the moment you land at Sydney Airport.
At The Flights Guru, we specialise in finding the best deals on Business Class flights to Sydney and other top destinations around the world. In this article, we’ll share tips and insights to help you feel confident and prepared for your long-haul flight to Sydney.
Dress for Comfort and Climate
Plan ahead when choosing your outfit for the long journey from London to Sydney. Think loose layers, breathable fabrics and even compression socks; comfort is key. Temperatures can fluctuate during flights, so wearing layers is always a smart choice.
Even though Business Class offers flat-bed seats, high-quality bedding and a more spacious environment, wearing soft, breathable clothing makes it even easier to relax and enjoy a long journey. Footwear is also important: choose shoes that are not only comfortable and roomy but also easy to slip on and off, both for in-flight comfort and smooth airport security checks.
Book the Right Seat, Early
When flying long-haul, your seat matters, and in Business Class, you’re spoilt for choice. From lie-flat window seats with privacy partitions to centrally located pods perfect for working or relaxing, booking early helps you secure the best spot in the cabin. And with help from The Flights Guru, you can get expert advice on the most comfortable layouts on your chosen airline.
Pack Smart in Your Cabin Bag
No matter the journey, what you bring in your cabin bag can make a huge difference to your comfort and the entire experience. Think practical, light and useful. Business Class travellers benefit from more generous cabin bag allowances and additional storage space around their seats, so you can pack a few extra comforts without worry.
Here’s a checklist of carry-on essentials that will help keep you feeling fresh and comfortable in the air and within arm’s reach:
- Noise-cancelling headphones
- Travel pillow and sleep mask
- Hydrating skincare products
- Toothbrush, toothpaste and wipes
- Snacks and a refillable water bottle
- Device chargers
- A change of clothes
Stay Hydrated and Eat Light
With premium wines, curated menus and on-demand dining, Business Class makes eating well at 35,000 feet a pleasure. But no matter how luxurious the experience, staying hydrated is still important, especially on a long journey from London to Sydney.
Aeroplane cabins have very low humidity, which causes your body to lose moisture more quickly than on the ground. To help your body adjust to the time difference and arrive feeling refreshed, ensure you drink water regularly throughout the flight.
While it might be tempting to enjoy extra coffee or champagne, it’s best to limit caffeine and alcohol, as they can worsen dehydration and contribute to jet lag. The same goes for heavy meals; lighter options are easier to digest and help keep you comfortable throughout the flight.
Move Often to Boost Circulation
Keeping your body moving during a long-haul flight helps improve circulation, which reduces the risk of blood clots and prevents uncomfortable stiffness and swelling. You don’t need to be on your feet for the entire journey. Simple in-seat stretches or walking around the cabin every few hours can make a big difference to how you feel when you land.
Thankfully, Business Class travel makes it easier to move around comfortably, and the extra space at your seat means you can stretch without needing to leave your pod. Something that’s appealing when enduring such a long journey.
Adjust Your Sleep Schedule Before You Travel
To help fend off the worst of jet lag, start preparing a few days before your trip by gradually shifting your sleep and wake times. Although you'll be able to enjoy quality rest on a fully flat bed in Business Class, adjusting your routine in advance helps your body adapt more quickly to Sydney’s time zone, which is an impressive nine hours ahead of London.
Make the Most of Business Class Flights to Sydney from London
Flying from London to Sydney is a major feat, but opting to fly Business Class will transform the entire experience.
