Cons: The carry-on baggage policy is ridiculously unfair and they don't tell you about the 7kg carry-on restriction at the desk but charge you 50 dollars at the gate when you don't have any other options but pay before you miss the flight

Mediocre 2.0

Pros: Only that it got us there safely.

Cons: Awful customer service and ridiculous baggage costs. We were traveling internationally and didn't have internet access at the time. We didn't realize we needed to "pre-check" our bags. It cost us double the amount of our flight cost to check our bags. They also carefully checked carry on weight at the ticket counter but then never tagged the bags and we had to have them reweighed at the gate. They also were ridiculously strict on carryon weight per bag. Don't get their policy when my husband and I weigh a total of 300 pds together and they can't be flexible on 1kg of carry-on weight. They also said they took American express cards (which does not charge us an exchange fee) and their machines wouldn't accept it, so I was charged an extra 3% via my credit card. Staff were surly and not helpful. Will never use Jetstar again

Pros: No the crew weren’t amazing & the seats were just okay. The flight was pretty full. The guy driving made two safe landings at Avalon

Cons: Jetstar - c,mon, it’s an airborne bus really.

Excellent 9.0

Pros: We were given delay updates regularly, even when the delay time remained consistent.

Cons: We had to empty our water bottles prior to getting on board which felt like a waste of resources. If it is necessary to do so, maybe it would be beneficial for the staff to let us know why we have to dump clean water down the drain.

Cons: Flight cancelled because internet went down on site. However, Virgin Australia and Qantas airlines were able to paper book their passengers and fly to destination. Jet star couldn’t do the same. Even though the internet came back up Jetstar couldn’t complete the passenger flight check in. The Airport staff stated the internet was a risk and instead put 200 people on buses and drove us 5 hours across a 42C desert. Somehow driving across the desert was safer. The icing on the cake was the Internet stayed up for the next hour prior to our bus ride and within the flight crews crew day. So, we could all have flown home with the Jetstar flight crew who actually flew back to Sydney. Yes missed the fireworks and expensive hotel stay on New Years Eve. Finally, Jetstar rebooked is on a flight to Adelaide then to Sydney so we wouldn’t arrive until 945pm. I certainly didn’t appreciate my direct 3 hour flight being turned into a 5 hour bus ride then a 7 hour flight. Oh, please tell them thanks for the piece of cheese and two crackers, apple and apple juice for dinner. What could be done better.....eliminate Jetstar from your list of service providers.

Mediocre 3.6

Cons: We booked through Kayak and weren't told that when you book a flight with Jetstar, you get NO BAGGAGE ALLOWANCE. ZERO, ZIP, NIL. We didn't know this and assumed like other Australian and New Zealand carriers, we would each get one free bag, so I went online and paid $25 for a third bag. When we checked in for a domestic flight, we were told that we would have to pay $400 to send our luggage with us. THAT WAS MORE THAN WE PAID FOR OUR SEATS! We were also told that had we paid for our luggage ahead of time, it would have only been $60. Be very careful if you fly this airline. Make sure you know what is and what is not included with your ticket, especially if you use a third party to purchase your tickets. PS - All drinks (including coffee, tea, soda, etc.)are extra. Frankly, I'm surprised they don't charge for using the toilet in flight

Pros: We arrived safely and on time.

Cons: The pricing seems low when purchasing the ticket, but we were charged $45/bag for our carryon bags that could easily have fit in the overhead bins (and on a separate flight with another airline that is what we did). Seems like a money grab to charge for the carryon if it weighs more than 7g or whatever small amount. Just take that cost into account when booking your flight.

Prices are per person, are for e–tickets and include all taxes & fees in AUD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
