The flight almost landed in Bahrain but the captain decides not to and the excuse was bad weather. So he just turned around and went back to Abu Dhabi. There was no plane for people to board Abu Dhabi and were left stranded. Thankfully the airport staff re-booked everyone immediately and dealt with the situation efficiently in a professional way. I was delayed by at least 8 hours. There was no email from Etihad about the canceled flight or an apology. It was a bit disappointing given that they are my favorite airline.

The flight left > 2 hours late from JFK to Abu Dhabi, and my connection was changed midair. Instead of changing it to the next flight, they changed it to a flight 16 hours later so I missed my entire day of meetings. The paid internet did not work inflight so I couldn't check my connection or receive emails. The crew was not friendly, and they also wouldn't give anyone any information about their connections during the flight, which resulted in ~80 people rushing the crew and the desk. It was very messy.

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.
