Atlanta airport is super duper organized!!! No problem getting tons of people through passport control & customs! Lots of well English speaking guiding staff- i was delighted!

On the international aircraft, 767, the monitors were smaller and hab on the domestic flights flight, the picture was way too dark to enjoy & sound out of one earpiece only

The plane was newer and the flight itself was good

Poor service onboard. Flight attendants showed little care and were curt. Ordered halal meal but were given vegetarian. It was bland and tasteless. My wife ordered drinks that never came. The armrests were stationary adding to the discomfort. Unfortunate how the international service experience is so much worse than domestic.

Glass of water and a quick flight was all I needed. Went very well.

Small delay waiting for the walkway arm at the gate otherwise we’d have been early

0 space felt like two people were sitting on top of me the entire flight. Seats are so small. No room to even put my arms at my side. I'm 5'9 and my knees were scraping the seat in front of me. Uncomfortable the entire flight. only nice part of the flight was the captain and crew.

Boarding was quick and efficient.

- Paid EXTRA for an emergency exit row and it felt like I was sitting on a hard wooden box the entire flight. - Food was awful/barely edible. - Plane was old, dingy and dirty. Window shade was broken.

First off I’m a Diabetic and some of my diabetic medication and or supplies are with me and some in my LOST checked luggage. I currently say lost because it Day 3 in Ibiza and the luggage never left Newark with my flight originally and is supposedly in Barcelona while I’m here. Called everyday for updates on my bag and they give you very little useful info. Oh and the 7:45 departure last Thursday didn’t leave until 2:30am, then they kicked us out of our economy plus seats picked for comfort and tossed us in middle aisle seats some place else which were ridiculously uncomfortable. There’s no entertainment except in first class and this is a 777 huge jet. Filing a claim, sending a letter to their ceo, a letter to he DOT, and grabbing a good lawyer friend for counsel on this because it’s a disaster. I had to buy everything I needed which isn’t enough and I’m also running out of diabetic supplies since the rest I’d my lost / delayed luggage. So delayed flight by 6hrs, kicked out of original seats, lost and delayed luggage, airlines seems to refuse to send it to my hotel through other carriers, 3days and no luggage and wondering if they are going to send it to Ibiza while I’m heading back to Barcelona today. No one calls me or emails or updates me on any status changes of where my bag is and what’s going on. Their customer service sucks and it’s some guy or girl in another country who gives no fks about your situation. I will never fly with United again

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.
