Your guide to booking Sydney flights

From booking to airport arrival, find tips to help you plan your flight with more confidence.
  • For the best chance at a low fare to Sydney, aim to book around 14 weeks before you fly. That window historically saves about 58% versus last-minute pricing based on KAYAK booking data over the last 12 months.
  • For flights to Sydney, recent KAYAK data shows that stronger deals tend to land around C$ 660 round-trip. If you see a fare below that threshold, it's a strong deal – book before the price climbs back up.
  • If you can choose when to go, aim to travel to Sydney in February. Round-trip fares historically average C$ 730 that month – typically the cheapest month to travel based on the last 12 months.
  • Before you book:

    • Check the route's typical price range so you can spot a deal.
    • Confirm baggage fees and seat selection costs on budget carriers.
    • Verify whether you need any travel documents beyond an ID.
    • Pick a departure airport, since your nearest may not be the cheapest origin.
  • Shift your departure to evening to save up to C$ 60 per round-trip. Evening flights to Sydney average C$ 843 compared to C$ 903 for noon flights. See the time-of-day chart above for the full breakdown.
  • Bag allowances vary by airline, fare type, cabin class, and route. On flights to Sydney, some airlines may include bags at no extra cost.

First time flying WestJet airlines and it was a wonderful experience!

First time flying WestJet airlines and it was a wonderful experience!

It was ok. Jet was ok but it lacked many convinces we have experienced on other airlines such as in seat entertainment. Space seamed more compact than other airlines. They did not provide the gate to gate assistance we arranged for for our mom who needed a wheel chair.

For some reason pretty much all zones were called almost one after the other and we all ended up standing without moving for what seemed like a long time. Definitely not WestJet’s fault. Likely the guys in hiviz vests at boarding desk. The big problem was zero explanation. If there is a good reason for something people will understand. As a consequence of this delay flight was quite late leaving. Zero entertainment on board. I’m a Rewards member but was unable to connect to the Wifi. First world problems, I know. Flight was otherwise excellent.

The crew was excellent. The turbulence was very bad and they were unable to serve our dinner. The captain informed the passengers that we were going to get water and snack instead. They provided us ample snacks instead. Otherwise the trip was good.

Delayed but they wouldn’t tell us tell after boarding was scheduled to start. So it’s like we know it’s delayed why won’t they say anything?? How long? The. We ended up sitting on the tarmac for 2 hours before they finally cancelled the flight. Bad!

It wasn’t bad but I swear their planes keep getting smaller and cramped so it was uncomfortable for such a long time. Also the food is just okay they need some different options

Friendly helpful crew but that did not make up for cramped, uncomfortable seating. Anyone over 5.5 feet and 150lbs is going to feel crammed into the tiny space they have allotted for seating unless you are a special rewards customer, then you get the properly human size seats. With the outrageous price of flying these days, even in economy, the very least they can do is provide you with a comfortable seating experience. Especially since if there is any kind of delay on the ground you're likely to be stuck there even longer than your scheduled flight time.

Check in through Kayak is IMPOSSIBLE due to the fact that Kayak & the airline of your choosing have different confirmation and reservation codes. You have to call the airline to find your actual information. My brand new KOBO Libra Colour 2 was destroyed somewhere in the security line. When I put it in the bin it was fine, and when I received it back, the screen was destroyed. Awesome. The boarding was a nightmare as people rushed to the gates prior the their boarding zones. I was seated between a father daughter duo who when I suggested I move to either side so they aren’t separated they said “no, we chose this on purpose.” They proceeded to talk over me, pass things over me, use my foot space, and lean on both sides. When we landed, the father was one of the first up, even though we were in the middle/back area. He then rushes his daughter to the point she quite literally clammers over me so they can push through people. The food was off putting: spinach & ricotta in a red sauce is a weird choice. The bun was fine. Tony’s chocolates were a great choice, though. The first flight was terrible. The second flight was much better. I was in a state after the first flight, and two of the flight attendants did a great job supporting the intense nausea I was suffering from by providing a large bag of ice and multiple ginger ales.

Really impressed. Organised boarding arrangements, nice new plane with decent seats. Professional yet humorous cabin crew. Nice meal and snack service, all really impressive.

We were not able to board the flight to Halifax. Westjet switched to a smaller plane and we were booked on a later flight which was not acceptable to us. We were told that they attempted to contact us but did not have contact information. Nor did either Kayak not Kiwi advise us. In February I booked a flight to Sri Lanka through Kayak with FlightHub for myself and a friend. We were advised of a change in schedule and because I was travelling outside of Canada at that time, my friend, Louise Lore, contacted FlightHub and revised our itinerary. Our original flight from Toronto through Frankfurt to Mumbai was to arrive in time for us to catch an 8:45pm flight to Colombo, Sri Lanka on February 28th but because of the change did not arrive until 1:00am February 29th. When I arrived in Mumbai I was told that my flight from Mumbai to Colombo had not been revised and that, because I was a no-show for my flight all of my tickets had been cancelled. Ms Lore spent from 2:30am until 5:30am on the phone with FlightHub trying to rectify the situation. She was told there was nothing they could do and a supervisor refused to speak with her. The next morning I went to the Lufthansa office at the Mumbai airport and the problem was resolved in less than 15 minutes. I will not be booking through Kayak again. Both experiences have been disastrous and I cannot imagine going through this again Linda Toole

The long delay was the worst part of the flight.

The airplane has been replaced and late night layover have been extended from 3 to 7 and the only compensation was a $15 food voucher after most restaurants have been closed, not helping with children after a 18+ hour international flight

Was notified on a timely manner of any changes, if any, of the flight schedules.

My original flight was cancelled -- but I have to mention the excellent service I was given by the agent working at check-in who found me an earlier flight -- and helped me navigate security, ensured my baggage kept up with the quick check-in and boarding process -- and just generally made the re-booking process a breeze. Thank you! On flight was fine, but we unfortunately meant no in-flight service -- no water, or coffee (it was an early morning flight...), but the crew was pleasant and accommodating throughout.

No in flight entertainment on a 750 mile flight. Made you join their "program" to get it. It was free on my first leg of the flight from Cincinnati to Toronto. In addition, there was brief period of turbulence that prohibited the crew from serving refreshments. They used that short interruption as an excuse to never serve drinks at all. They had ample time to do so and chose not to. They went around serving half cups of water instead rather than have their carts in the aisle with drinks.

It was great other than the plane was really small

No entertainment. Luckily I was the only person in that row. Small seating

Four hour delay, no communication and multiple reasons for delay. Rude counter person even though I had a business class ticket. Bad experience all around.

I really didn't flight from Toronto to Sydney Because my flight was cancelled for the snow But you guys help me lot and put me in the flight from Toronto to Halifax I give you at 10/10 because was really good Just I had to drive 4 hours to be home

I wanted to change the dates of my flight and was not able to do. Had to cancel it without getting any refund. Bad customer support and worst experience ever.
