The airport is an excellent fit for travelers seeking to explore Australia's largest city. This airport also features reliable and convenient connections to other cities and attractions in Australia, including domestic flights and ground transportation options. However, if you’re visiting Western Australia, book a flight to Perth International Airport (PER), which is the hub for international flights in this region.

  • Can I rent a car at airports in Australia?

    Yes. If you’d like to get behind the wheel during your stay in Australia, you’ll find car rental counters on-site at all major international airports in the country. Chauffeur services are also available, which may be a more comfortable option for first-timer visitors.

Each terminal at SYD features a taxi rank, while the Airport Link train service to the city center is available from Terminals 1, 2, and 3.

  • What are some things to do during a layover at SYD?

    If you are stuck at SYD during a layover, you can pass time at the airport lounges, which are accessible by paying at poor or purchasing a membership pass.

All was good, the only thing was it didn't run on time.

All was good, the only thing was it didn't run on time.

Overall excellent but the Captain kept the seat belt sign on for far too long, especially at the beginning and end of the flight. It was 2 hours after take-off before the crew were able to start the service (on an 11 hour night flight, reducing our sleeping time) and the seat belt sign on went on during breakfast (90 mins before landing) and was not turned off again until we landed. This made for an uncomfortable journey of trying to limit fluid intake because it was unclear when the toilets would be available for use.

The staff and crew on board were excellent. Business class however, was very weird. I thought we would have individual pods, but the way it was set up was unexpected. Not very private and If you wanted to lay down, you had to have an entire bed made up for you by the crew, rather than how Delta one works where you could just lie down whenever you feel like it. It was a 16 hour flight. I chose not to have my bed made, and that turned out to be a good idea because everybody who had their bed made had to wait for the crew to roll up their mattresses. So strange!

Couldn’t request a vegan meal somehow but I noticed other people getting them

United flight from SFO to PDX was cancelled. I will ask for a refund. Had to book on Alaska

They announced food service but then never came around. We also couldn’t land so kept trying to get to runway and then had to come up and go around happened like 3 times and cause the child next to me to start throwing up

Good food and entertainment options. Great Staff that were all welcoming and caregiving.

The recline on the seat in front of me came back so that I was staring at the top of the man’s head in front of me the whole trip. He refused to bring his seat back up twice every time he was instructed to do so and only relented when he had a tray of good in front of him. And then right back in my lap!!! Horrible man!! I complained to the staff multiple times, but no one would address the issue. Otherwise, it would have been a perfect flight.

There was a snafu with confirming seats at check which left us in limbo for the second leg of our trip. I believe the ANZ app is not well integrated with the systems at the terminal resulting in this disconcerting error.

Flight was canceled due to technical issue shortly before the check-in counters opened. Passengers were rebooked on a flight three days later. Request to be accommodated on Air Tahiti Nui could not be processed. Customer service sorted out the refund after calling and being put on hold for almost an hour.

Flight delay was informed at the last minute. Food quality is not up to Qantas standard I was unable to book an online boarding pass on any of my 6 flights.

Following a marathon flight riddled by delays and changes from Santiago, Chile, my flight to Melbourne from Sydney was on schedule but I was transferred to the next flight. The reason by ticketing and the floor manager was I missed the entry to flight by one minute! That's right, the emphasised that if I was 1 minute earlier I would be on the flight. I asked what was the point them emphasising 1minute overdue and how that helped me or the situation. They didn't care at all. Replying that if it was one minute earlier they would've done something and smirking delivering the information. Australian's do call Australia home, Qantas calls Australian's suckers.

Rescheduled after ticket purchased and issued, not 2 or 3 times and not a fourth but by 5 times, by Qantas, that's right, 5 changes! Forcing an overnight stay in Chile and need for visa. Qantas can no longer provide basic services as a national or international service provider. Professionalism is extinct and the provider needs to be mentored and educated in perfecting who to operate as an airline. Qantas is the spirit of Australian dissatisfaction.

Amazing! Was put on the earlier flight and I requested for an aisle seat and was given it. Thanks Qantas!

The staff we fantastic and seemed to work very well with each other

Business lounge in Melbourne mediocre. Look at Emirates or Qatar, Qantas! Great friendly crew. Food was good but Emirates is a level above. Business seat good. But can’t compare to Qatar. Main reason for booking Qantas is loyalty and terrific connection via Perth to LHR.

It's only a short trip from Sydney to Melbourne, which i have done many times. The trip met my expectations

The crew were amazing - A great job. They made me feel special and valued.

I really appreciated the fact that when I checked my bags at the Quantas counter after arriving from an international flight an hour early, the agent noticed I had a very long layover. He then found an earlier flight that allowed me to get to Cairns several hours earlier than I planned. That was amazing because I had already traveled over 20 hours and wasn’t looking forward to such a long layover. It allowed me to see my daughter and grandchildren much earlier (it had been two years since I visited last).

Qantas cancelled my flight for no good reason and rebooked me into a middle seat.

Nothing beats ANA customer service on my opinion. Maybe because of their Japanese culture (and food). Arigatō

So so. Terrible aircraft choice for that leg of the flight.

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

Hated every minute of it. This flight should have only taken 1.5hrs but was delayed over 10hours. Now I am being told I cannot be compensated or refunded my ticket price or extra leg room, which I purchased but did not receive, because the airline is throwing the blame on the 3rd party I purchased tickets through and 3rd party putting the blame on airline. No one wants to help. They received their money and that's all they care about. Im going on 3 days of still trying to get to my final destination, had to cancel car rental, car insurance and hotel. Currently staying in airport until hotels open up. Thank you Lufthansa, Kayak, Underpricer and United for making this trip the worst ever.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Just get Economy Plus for international flights, so worth it the extra room, bigger seats…

This flight is frequently delayed. The connections seemingly are more frequently delayed. I’ve missed connections as a result twice on the same route to charlotte then Charleston. Final destination arrival has been the next day, twice in a row. No pilots, no crew. Too many excuses. Unfortunately, my days with American are over.

Entertainment was okay not because anything was wrong but it is a short flight so having no wifi is annoying but understandable. Crew was outstanding as usual

It was spectacular. I had basic Economy and was given so much space and their seats lean back so far. Staff was superb, food was superb, everything was superb, Finnair is Fantastic.

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

The flight was great but board was a nightmare. The gate was changed 4 times during the layover period

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Cold air blew constantly on my legs almost making me numb.

Food was icecold or frozen including breakfast. Hopeless service. Rude crew.

The flight was very uncomfortable and there was no snacks served for the 13 hours international flight. In addition, the flight was delayed 3 hours

Due to a strike taking place with the airline, it negatively impacted my flight in multiple ways. My flight was delayed over 2 hours and the food served was mediocre at best.

Terrible experience! All flights delayed, staff had no idea of what they were doing, and at the end luggage lost for 2 days!

Cabin crew were great. Seats are criminal for tall people

Flight was delayed 1.5 hrs due to problem with a previous flight to mine; I was informed appropriately via Text & Email, however, website did not keep up with messages sent by nearly an hour. When checking-in warm & friendly reception at check-in desk until female Air Canada Rep noticed my flight number and instantly pivoted to a condescending & sarcastic comments about getting my bag checked in since I’m running so late; then tone instantly changed again few minutes later when she muttered, “Oh, they’ve delayed it” another sign systems & worse front line staff, not fully informed or simply not reading their flight status updates. Flight crew were very friendly & did a great job trying to make up lost time due to the delay.

It was great, love the experience and will definitely recommend 👌. Communication was great

My flight was great! Gate attendants and crew were great… pleasant and in good spirits. Flight delayed several hours and we were well informed of the status while on plane. Thank you!

The fact that I got to Toronto alive and well and safe is a huge plus. I thank the captain and crew for a safe flight The comfort of the aircraft leaves much to be desired. Human beings should not have to be that cramped and squashed on a flight that we pay a lot for and even have to pay for lousy food choices The cabin crew were pleasant and helpful Kudos to them as the flight was packed to capacity and there was a lot of work for them in a short space of time All in all a good experience, but too cramped

It was great to check carryon luggage at no charge when there was no room for ours. A hidden benefit of having low-tier tickets. Also great to stay off plane as long as possible. Airline gave us seats we wanted on this last leg, again at no charge.
