OK 4.0

Pros: The crew made a bad decision concerning me and another passenger. I had extra leg room in front of him and he still insisted on crushing my knees with his reclining part of his seat. The stewardess choice to side with him because it was ok to crush my knees because he paid for a upgrade in seat,

Cons: I will be filing a complaint about this matter soon and request a refund for the total disrespect of me as a paying customer,which they did not value at all

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.
