Clean modern comfortable. Food could have been better, I only ate breakfast I wish they wouldn’t wake sleeping passengers who would rather sleep through dinner. No tea or coffee for breakfast

Clean modern comfortable. Food could have been better, I only ate breakfast I wish they wouldn’t wake sleeping passengers who would rather sleep through dinner. No tea or coffee for breakfast

Food was terrible , uncomfortable seats, WiFi did not work, will never fly Singapore again.

Fast and efficient flight. Wifi worked well. Food selection could have been better

Overall the airline tried to give excellent service. The wheelchair service was bad at SFO. My baggage was also delayed but I thank them for taking the trouble to find it and deliver it to my home.

They ran out of the second choice of food was stuck with fish

Excellent crew service. Professional, courteous. Service with a smile. Good food Very decent flight experience

No frills airline with minimal leg room and no entertainment

Wish the seat don’t have restrictions, can’t fully insert backpack all the way inside.

Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing

I was in a middle seat where I felt a bit too cramped otherwise the trip was good

Worst kayak is worst ill never ever use kayak ever again !!

The flight was delayed and the service was not good. All the new serve was beef and we don’t eat beef so we ended up buying our own meals at the airport twice.

It went well except at delhi airport they told me that my flight is canceled and only after talking to manager they were able to find seats for me and my wife

Very nice experience in business class. Flight attendants were attentive. Foods and beverages were very good.

Offboarding in Dubai was a bit confusing. The bus dropped us off, we passed the security, and then we were again in departure, no clue, no guidance on where to get our luggage

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Everything was great except the boarding experience. After the check in, they "packed us" in a small area, very hot there. It would be nice to be aware of this, I'd wait on the outside area

Very good from the beginning to the end. Amazing experience

There is an issue with A380 when it arrives in Munich, because a business class passengers like me have to wait for the first class passengers to disembark, which takes some time while you are also offloading economy passengers this causes an issue at customs where your business class passengers end up behind a large bulk of economy passengers This is a frustration and the early dislocation should be and is supposed to be a benefit of business class

I would have liked less packaged snacky stuff, more fruit. The crew was great.

Qatar was pretty OK for their services but Arangrant was awful at theirs and frankly lied to me. Qatar offers four business class fares and only three of them allow lounge access. This is a horrible policy when you pay so much for business class and shame on them for denying the simple use of their lounges for this confusion. When I requested my business class ticket with Arangrant I knew this and specifically told them I would only purchase the lowest class business seat that would still permit me lounge access on all legs of my trip. They lied to me and said I did and then I was refused this service on my return flights. I had no less than 4-8 schedule changes and got screwed by a late departure from DCA on my double connection to JNB. I lost nearly a full day on my outbound and then had little to no use of the lounges on my outbound flights. To then be denied access on my return flights made the 27 hour trip home pretty awful. Kayak should no longer work with Arangrant as they are dishonest and liars. Qatar should price all four of their business class fares to include lounge access and stop the insanity they have forced on people. My return trip home nearly ruined my entire trip to South Africa and I blame Arangrant for telling me lies and for Qatar for offering insane rules and regulations on such expensive business class fares. For the money I paid to Qatar, I did not receive the full services I was promised. I will probably never use Arangrant and their ignorant services ever again. I will question whether I ever fly on Qatar Airways again as well. When you pay so much and get such little in return, it leaves a bad taste in your mouth. Arangrant gives the whole industry a bad name and Qatar is not far behind them. I can honestly say that the wretched service and way I was treated by both have soured me on travel companies and airlines. It is bad enough that we have an idiot, felon, racist and bigoted president and administration to contend with while he has started an illegal war, I did not expect to get screwed over by Arangrant and Qatar as well. Shame on all of you.

Impressive as always. It is the airline of my choice, The dessert on the 2nd flight DOH-IAH was somewhat dry (the cake with cream etc) Check-in and boarding experience was fantastic, with the exception of CCU airport where chk-in staff refused to help with aisle seats stating the flight was full and accommodations were beyond him. Once I boarded there were plenty of available aisles. I was disappointed that this could not be done by self during online chk-in nor at the airport. Nothing more to add. Overall a good experience, TY QTR

The boarding process was awful-the computers were down and there was no way to check in. Took extremely long, very chaotic and no guarantee our bags were even getting on the plane. I was also delayed and took away from any time i had to catch a connecting flight.

This flight was a very good trip for us. The crew were very friendly and helpful. They made arrangements for my husband to have assistance in boarding. We were not expecting a meal, so it was a pleasant surprise on this short flight to have a meal and beverage from a very courteous crew.

All great, because I was given a seat with extra legroom on this part of my trip.

I wish I knew in advance that the connecting flight was by indigo air

Excellent service. The personal adaptation of menus and the individual timing of service of them is fantastic.

Awesome hospitality, awesome staff, awesome food & awesome travel time. Thanks

Good. It would be great if comfort seats were available

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.
