Excellent crew services

Entertainment system is rather tired for today’s standard for first tier airlines, in particular the headphone jacks which may not work from wear & tear. It’s a hit & miss whether the sound works or not. Obviously mine didn’t on one side this time. Very frustrating if you are on a long flight and there’s nothing you can do if the flight is full.

The crew ask to change sit with another passenger and I said ok, then start to demand I move so they can sit together.i guess I didn’t move fast enough to suit him. Of course changed there mind. Maybe a race thing with me being black. The crew show lack of respect toward me.

We spent 2 hours at the check in because China eastern changed our connecting time and we were going to miss our flight. The food was terrible, they lost my husbands luggage. We are on our honeymoon and he has no clothes. And they put us up in a very dirty hotel.

Liked the information provided and smooth boarding

Drink service was spotty, very limited and not pleasant. The meals were skimpy on portions, and variety. Only two meals and no snacks were provided. Was difficult getting more beverages. Only beer and wine. Small seats but then every airline has small seats these days. Seats also do not recline as hey once did

I’ve flown with a lot of airlines in every class. This was an economy class flight and still the food was better than I’ve received in business class on American. The seat was comfortable, the entertainment options varied and extensive and the cabin team were amazing. They clean the bathrooms between uses. Seriously how do other airlines still exist?

No free upgrade? ;-). But that’s unreasonable. I love this airline having not flown with them for 4 years I don’t understand why!

got us there on time, Customer care was helpful but wish there was an easier way to fix a problem at the airport instead of calling in to a help desk.

they didn't have the arrival cards for me, which they usually do. Traveling with 4 kids by myself and having to do customs by myself without the time on the plane to work through the cards made it difficult. Also there was a typing error on one of my children's tickets that was an airline error but still requires a phone call from me and a fine to fix even with the plane leaving in one hour and having three other children at the gate waiting. There has to be an easier way to fix a mistake that happens in the airport.

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.

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.
