Customer service...very helpful and accommodating. Good food. Easy transfer from domestic to international. On one of our flights, a 39 minute one, they served a substantial snack (yogurt, breakfast biscuits, oj) and tea, coffee, etc. Amazing in that amount of time!

I tried to think of something but I couldn’t.

Ahh Qantas. What a relief after an internal US flight on a US carrier. Spacious, comfortable, on time, good food.They even comped us for luggage delayed that was not their fault.

Great choice of entertainment. Served good food often with nice menu selection. Seats a bit tight as with all airlines. Fruit was fabulous and fresh - there were none left when I requested mine, but the flight attendant said there may be some left from other servers. Within a few minutes, she did bring one which I was thankful as I didn’t care for the other selection.

Close seats especially when others recline, but we were lucky on this flight no one did as it wasn’t a full flight so people moved around.

There was an excellent selection of movies to choose from. Breakfast was actually pretty tasty, and snacks and water were offered quite frequently. The seat was reasonably comfortable, and reclines back a decent way. For how huge the plane was, the boarding process was super fast and efficient!

Seats were still rather cramped for my poor husband, who is 6'3. It is very hard to get out of your seat if you're in a window and all the seats on front are fully reclined, and I am relatively spry! Can't imagine an elderly or debilitated person trying to do so! The in flight movies were great, but you had to use the headphones they provide, and none of the 3 pairs I tried worked well. All had constant static. Although the seats recline far, they also do it abruptly and are hard to get to come back up. The dinner (we had the beef) was not very good. The quality of the ground beef was what you would expect from a fast food place. The worst part of the flight was that the sat ALL the infants in the same area on the plane, and all right around us. 5 of them, to be exact. 17 hours of on and off screaming babies! My husband had to move to a different seat to get some sleep! Thankfully, I can sleep through anything. Overall, less terrible than I expected a 17 hour flight to be, but could have been better. Some crew were very nice and helpful and others not so much. The first woman my husband asked told him (rather abruptly) that he wouldn't be able to use his CPAP machine. Then a really nice guy helped him get it set up. The turbulence was a bit scary for me, and the way the captain would announce it didn't help! He'd just say "all passengers and crew be seated and fasted your seat belts" in a rather grim tone as the plane shook violently.

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

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 rentals 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.
