Nothing

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.

I am used to flying Frontier because of cost but recently traveled Delta and boy did I feel completely spoiled! Not only did my other half get our bags for free due to his status with Delta but the amenities they offer and the comfort of the economy seats compared to other airlines is a major difference. As a chronic pain patient, if I can find a Delta flight for a little more, I will be booking with them for sure! Highly recommend them!

Qantas provides a nice welcome when your board domestic flights in Australia like the one we took today between Brisbane and Sydney not just on their international flights. They greet you when you board, don't feel like a number like domestic flights in the USA be it American, Delta, United, or one of the others. They provide free premier movie access, serve a nice warm meal and drink, and make you feel welcomed - Keep up the great work Qantas, you could give the USA airlines lessons on how to treat passengers.

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.

Way too cramp even for airplane standards. When food was served, it’d take at least 30 minutes for the flight attendants to collect rubbish, and since the seats are so small and I can’t keep the tray table open without pinching my spleen, it was really terrible. I paid extra for an aisle seat and was told there weren’t any.

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.
