The flight actually left.

Poor communication. Flight originally at 11:35, then 12:05, then 12:15... At 11:55, they said they would start boarding in 20 min. How can you do that and still take off at 12:15? Answer: you can't. Just be honest and keep us informed. Bonus: United sent me an email saying that connection had already left (it hadn't - thanks United! - awesome service as always!)

Flight was cancelled on our way back home from Gudalajara, was speaking to a representative for almost 2 hours to get me on the next flight the flight representative forgot to put me on hold and told everyone how rude i was, i was not rude i was just trying to get home. The representative couldn’t help me so i asked to be transferred to a manager, after 2 hours i was transferred and the manager hung the phone up. Long story short i called back spoke to another manager Yana and she was the rudest lady ever! She basically told me for waiting to long i will have to be placed on a flight 2 days after my cancellation flight. I started to cry because i needed to be home and she basically did not care so i took the date. Never again and i will warn everyone about this airline and their customer service!

They did not get my liggage to the connecting flight And here i am in Ukraine with no winter clothes at 7 below 3 days later

Customs officials are incredibly un-helpful and slow. I almost missed the next flight because of how slow was that part. I hope Delta can speak up for the passengers, because we cannot express that to these rude people.

Flight was fine.

My one complaint is the bathroom layout of the A320. Two tiny closet bathrooms in the back for all of coach and a much larger one much larger one first class (which is like 5 rows with a mesh curtain for separation). The coach bathrooms are so small a normal person can barely get in and turn around to close the door. I question whether a larger person would be able to actually use them. I also saw the flight attendant actively turn away coach passengers trying to use the first class bathroom when it was open (not standing in the aisle or anything annoying like that). That's ridiculous to have 2 tiny bathrooms for all of coach and also to make people walk all the way to the back of the plane when you are seated much closer to the first class bathroom.

Boarding was fine. And service was good.

TV controls didn’t work. So I couldn’t watch anything for the 4+ hour flight.

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.
