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.

  • Does Sydney International Airport have onsite hotels?

    Sydney is the primary base for Qantas and also acts as a secondary base for Virgin Australia and Jetstar. When you fly into Sydney from London there are many options for you to continue your journey regionally.

  • Can I fill up a water bottle at London airports and Sydney International Airport?

The London airports have also introduced water fountains to their terminals so you no longer need to buy plastic bottles of water for your flights.

  • What is the fastest way to get into Sydney from the airport?

    Sydney Airport is situated 8km (4.9 miles) from Sydney. The fastest way to travel is by train – the journey is 13 minutes and trains run every 10 minutes or so. You need to buy a ticket (Opal Card) from the station, Relay or WH Smith stores before boarding the train.

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.

Beqaa, a Lebanese street food restaurant and the fast-food option, Subway, exist in the food court in international arrivals at T1 and there are various coffee shops such as Toby’s Estate and Gloria Jeans in T3, and burger bars – Chur Burger and Bistro 2020 in T2.

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.

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.

Crew: Everybody was polite. People just need to get efficient and less reworking things. Entertainment: Could have move movies and games. The “music” section is a joke, only ONE available. Food: The food provided on the flights boarding in china needs a serious reworking. Too much oil, bad for your stomach, tastes too artificial and the eggs were a giant mass of green dough.

We were diverted to Chengdu, because of bad weather and finally made it to Chong King about 7 hours later

We bought an upgrade to Business Class at the airport but did not realise that it was not the regular Business Class. The 787 Dreamliner was very dated with the seats not as comfortable as other airlines and some things were almost coming off. We were then told that because it was an upgrade at the airport, we get to sit in the BC cabin but will be served economy class food. So when everyone else got served in china ware, we were given the tray you got in economy class. The wifi does not work. It only connects to watch movies (which is the same as what you find in the ICE) but the internet does not work. The cabin crew while were friendly, were not responsive. Overall, I will never fly China Southern again.

No good but was short flight. Both of our China Southern flights were on time. No surprises.

The flight was okay it was the kayak customer service that was poor, I have been trying to change my name on my flight ticket 3 days before my flight and nothing got done about it even tho I messaged so many times and phoned, all I got in return was that is was being processed and still to this day nothing has been done about it, I think it’s disgusting and un needed stress to the trip.

Traveling with the Chinese airlines , their service superior to the US Airlines , they are much more friendly and the seats are comfortable , In the past I flew with United , now ,United Airline will become history for me .
