FAQs for booking flights from London to Sydney

  • Are there smoking areas at Sydney Kingsford Smith Airport?

    The legislation around smoking in New South Wales states that it is an offence to smoke within four metres of a public entrance or exit. There are designated smoking areas outside of the terminals, which are clearly signed; however, there are none for those transiting through T1 International Terminal, so you will not have an option to smoke until you have exited the arrivals area.

  • How do I go about getting assistance in Heathrow Airport?

    There are multiple assistance host areas in each terminal with staff that can assist with general advice, directions or assistance for mobility-impaired travellers or those otherwise needing assistance. There are accessible facilities throughout the airport, including wheelchair access toilets in every terminal, SignLive service available for hearing impaired travellers, the Aira app for visually impaired guests and plenty of free-to-use mobility equipment, available by asking any of the staff at any area of the airport.

KAYAK’s top tips for finding a cheap flight from London to Sydney

  • If you’re heading into Sydney City from the airport, you can make the journey by train usually in under 15min. The train station is clearly signed and is connected to the north side of the terminal at the arrivals level. You can purchase an Opal Card from kiosks at the train station or from various convenience stores in Sydney Airport (SYD), or you can tap with your contactless Visa, Mastercard or AMEX. The trip should cost around A$ 18, but can be slightly higher if you purchase a single fare.
  • Those looking for a coffee and a meal after a long flight will find many options available at Sydney Kingsford Smith Airport. There is a wide selection of cafes, restaurants offering cuisines from around the world, bars and classic takeaway options.
  • If you want to pick up a few particular items at London Heathrow Airport (LHR) before you depart London City, you can book a personal shopping experience through Heathrow Boutique with an accredited stylist to find new favourite pieces to take home.
  • A number of airlines operate flights from London to Sydney. There are currently no direct flights from London to Sydney so your choice of airline might be dictated by where you want to stop over. British Airways flies to Sydney via Singapore while Qantas flights go via Dubai. Other popular airlines that fly this route are Cathay Pacific with a stop in Hong Kong and Emirates which also stops in Dubai. Singapore Airlines could be another option to consider with a stop in Singapore.
  • If you are flying from London Heathrow on Qantas First or Business class and need to do some work in the peace and quiet, consider going into the Qantas airport lounge in T3. If you are a top tier card holder in the Oneworld programme you can also use the lounge, but will have to pay an entrance fee if not flying on Qantas.
  • Can’t decide whether to book flights to Sydney from Heathrow, Gatwick or Stansted? With Emirates now flying from all these airports you can choose which airport you want to fly out of before booking. Stansted is 42 miles to the north east of London and the express train takes approximately 47 minutes from Liverpool Street Station in London. Gatwick is 30 minutes away from London on the Gatwick Express from Victoria Station and London Heathrow is 15 minutes from Paddington Station on the Heathrow Express.

Poor seats. Not helpful crew. The food was awful.overall very very bad experience. Traveled with the family of 5

did not get a notification about seat selection ahead of time. We didn't end up sitting together.

I was denied boarding at the Brisbane airport and it seems like I won’t get any refunds from the airline

In my return flight they couldn’t identify my ticket or boarding pass, I had to go to 3 different counters until I was able to get my boarding pass. The food was on, it was the bear minimum. They didn’t even recognise that I was a Muslim and can’t eat meat, chicken or pork. In one of the trays I believe they served me pork. The staff were very pleasant, but they need to be aware of their surroundings more carefully, one of them stuck her lower belly right into my face! I was shocked and very uncomfortable.

Overall I had good experience with China Southern airline. Nothing to claim. I hoped they could improve the meal quality that is.

Wow very impressed by the quality and attentiveness of service of China Southern. Lived the blankets! Will definitely fly with them again. Despite language barriers, a few attendants know enough English to understand our rudimentary Mandarin and respond to basic questions. Although they don’t explain the beverage and meal service on the website or ticketing documents, they offered regular beverage cart and snacks during the beginning hours and end hours of the long, transoceanic flight. A full meal at the beginning and end of the flight as well, and a midflight small sandwich (dinner roll sized) but we weren’t hungry and didn’t try that one. The expectation is that every sleeps during the middle of the flight. We were on a “redeye” departure from LAX with a morning arrival in China, so I don’t know if this service pattern is the same for other flights. The domestic flight we took from Guangzhou to Harbin offered conventional refreshments and meals like a US flight service. Note that they didn’t offer diet sodas. If you like to stay hydrated, I recommend bringing plenty of your own. It is served in small cups like any other drink. You can ask for a bottle but they’re tiny - about 6 ounces.

China Southern was not the problem. I booked my flight through Kayak and also received a booking reference and alert details regarding departure time and gate numbers… however Kayak NEVER actually booked my flight! We were stranded at the airport without a flight for a long awaited holiday!

The connection between LA and Atlanta was too much stress

Terrible boarding experience,,food is very poor that I I . Never going book this airline again.

The crew were kind, patient and responsive. The service was excellent, even though we travelled the cheapest economy class. We arrived at our destination 40 min early, which for a 15+ hour flight is a great bonus. The boarding seemed a bit "loose", but got us boarded on time, and the plane was off exactly @ 0:30 hrs.

tray table was inclined by 30 degress so could not use it

Flight was cancelled by air India. There was no explanation provided why the flight was cancelled. Found out that the flight was cancelled because the Iran air space was closed. Meanwhile, all other flights passing through that region were operating without issues. When asked to refund money for the tickets, being told that “ As checked, we wish to share that Flight AI 116 on 15 January 2026 from New York to Mumbai was cancelled due to Iran airspace closure, which were beyond the airline’s control. While such events can disrupt travel plans, we appreciate your understanding and patience. Our team remains committed to ensuring the safety and comfort of all passengers and takes all necessary measures to minimize any issues. However, we must inform you that compensation is not applicable under these extraordinary circumstances, in accordance with the relevant regulations.” Completed unacceptable and unprofessional behavior!

Bad weather in Amritsar cancelled the flight while we were at the gate in Delhi but the ground crew took good care of us and exceeded our expectations. Once on the plane, we enjoyed the best experience we’ve had on any flight in years. Their customer support was also impressively quick to answer and immediately helpful.

Old and filthy aircraft Boarding was free for all with no zones

Flight was delayed in phases from 84ppm to 2am. And at 2am it was cancelled. Only refund option provided and no stay was provided. Poor communication throughout and shameless behaviour from the airline with no regard for seniors citizens and those travelling with children.

Aircraft condition poor, no inflight entertainment, broken seats, seats worn, split armrests, flat seat cushions and seat would recline. Aircraft needs refitting completely!

Several seats in business class were broken. Some would not recline, others had other problems. They need to really update the seats and AV.

Boarding was through bus even though aerobridges were empty. Major mess

Flight crew was lovely. Bathrooms should have been cleaner. The handsets in business class for watching the entertainment are horrible. Very difficult to figure out which buttons are for what. I managed to get the flight maps on my screen but it wasn't easy. Never got anything else up.

This was a bery good experience as it was a newer plane . AI older plane bussiness class is bad .
