Our flight was 30 minutes late leaving which gave me a too quick layover. Newark Airport website doesn't advertise the bus terminals, just the trans (which means security) - but the flight attendants were so kind and told me exactly where to go to do the bus so I didn't miss my flight, although it was close!

Couldn't figure out why I couldn't accesss movies on my iPhone since I had downloaded the United App prior Also do not like that the free (always nice) entertainment is on a revolving scgedule so couldn't see any movie from the beginning.

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 email and someone from our team will get back to you promptly.
