As the flight is a long-haul flight you should arrive at the airport 3 hours in advance and you can choose to make use of one of the many Business and VIP Lounges available to you.

Comfortable seats. Be aware there is no alcohol on this airline.

Seats were comfortable. Be aware there is no alcohol on this airline.

Every thing was very food except the meal. It was a sandwich of something like a beef kebab. It was really bad in terms of hardness as well as taste. We were a family of 7 persons non of us could eat it his sandwich. Cake was good.

It was very nice flight only suggestions to upload recent videos and English subtitles. Thanks

Wheelchair service is not available right away on Kuwait Airways

Everybody was so nice to treat me good all the workers When I came to Bangladesh there was just a little problem with the luggage but I got my luggage it took like two hours Other than that everything is good

Food quality should be upgrade. Plastic spoons looks like not good as well as food quality not up to the mark.

Everything was great specially the seats was comfortable even I was in the economy and the food was really Great👍

Not much on entertainment, food was good but not delicious, flight was on time

The crew was attentive and kind. The business class cabin wasn’t very full during the flight so the service was catered to your specific needs.
