Movie selection needs to get better and maybe you should add one more snack because for a 12 hours flight it wasn't enough. I was hungry at the end.

On time arrival; professionalism.

The business class seat is cramped for business class standards. I also wanted seconds for dessert but somehow I was made to feel it was not allowed, that the FA has to check with someone if there was enough on board. Mind you the plane was not full.

I was traveling for medical reasons and the Delta crew took great care of me, made sure I was at my connecting gate on time, and even put me in a better seat on the plane. Not sure if that was a coincidental upgrade, or intentional, but it was perfect.

Other than the delay by the Hong Kong Airport controller, everything went smoothly. The plane was late to Seattle.

The luggage custom clearing would be much better if we could do it like the Vancouver BC where an electronic monitor was used to identify one's luggage without the need to handle them manually. Much more efficient and allowing folks to get on the connecting flights easier.

I appreciated the food and service from the stewardesses was great. The red embroidered apron was a nice touch.

My luggage was late, and I did not receive it until 24 hours after I landed in Hanoi. This caused a big inconvenience. I had packed my things very carefully, and most of what I needed the first day was in there.

As always, the crew and amenities were first rate.

We were initially told that our flight would arrive early. Then we sat on the tarmac for a half hour before anyone could be bothered to tell us we were waiting for the plane to be de-iced.

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.
