I liked the service from the cabin crew

I hate that I couldn’t use my phone on airplane mode. What’s up with that? I’m not a fan of Airbus. Boeing aircraft are superior

everything has much improved from my previous flight from LAX to BKK about 1.5 years ago. cabin was still a bit cold, but flight attendants were able to give me an additional blanket. they ran out of blankets last time i flew on China Eastern. entertainment was higher quality, food tasted better and snacks were available throughout the flight. boarding was also much more organized compared to last time which was like a angry mob scrambling to get on the plane.

The entertainment was giving some issues and the staff tried to resolve it. Eventually it came right by it self...

friendly crew

due to 11 kg total weight I had to check in a soft carry on bag resulting in :1/2 hour extra wait time and some crushed items. Vegetarian food was pretty tasteless.

Crew is always helpful and friendly. Riding in economy is never very comfortable. Love the little chocolates handed out toward end of flight.

Food is boring and repetitive. Current movie selections and TV shows were mostly uninteresting.

Quick boarding, on time, nice amenities near the gate.

The menu had a vegetarian and a chicken option, but when the trolley came around, they only had vegetarian options. We were in the fourth or fifth row from the front (in Economy), so it's surprising if they ran out of the chicken option that early.

Price was great - the aircraft was new

food was so so - no choice was given on the first meal - snack was a sandwich but the bread was very very dry - crew was very stingy in giving out drinks - half a glass for soda - found the crew not very friendly

No one to assist my friends enter the plane. No one to help with hauling minor carryon baggage up the outdoor staircase. Very difficult and no offer at all for anyone in a party of six to help. No lift and no one offered assistance in business class to help at all.once on the plane service was outstanding. Passengers in 70s and 80’s and no knowledge of the need to to climb stairs and without any assistance. Attendants watched the elderly struggle.

They missed me for breakfast despite my being awake and trying to get their attention. Then they ran out of one of the choices for both dinner and breakfast. This despite the plane being less than capacity. Also there were so many empty seats in the back but I noticed that some people were still being packed in like the flight was full. Emirates should do a better job of assigning seats to make as many people comfortable as possible.

After our trip from Cape Town to Dubai with Emirates which was not that great we where pleasantly surprised when we where bumped up to business class from Dubai to Bangkok. We did not expect this. Although we did not take advantage of all the extras business class has to offer we had a great nights sleep and the breakfast was superb. The cabin crew was excellent all the time. Thank you Emirates.

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.
