SQ is a market leader for good reason and its 787 this time was actually comfortable and the service top notch as always.

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

Never book through Kayak. They can offload booking to third parties that are completely horrible.

I loved the full Taylor Swift selection but felt that the other selections were limited, didn’t span the popular music eras nor a wide enough range of music genres. BUT the seat and bed were GREAT (it was wide, long enough, had great storage, firm enough to uphold body postural comfort). Outstanding crew and really great food - gourmet innovative dim sum breakfast so different from the boring standard fare offered by many other business class products.

Crew is excellent Wifi needs to be improved in order to connect to the internet.

First time flying with Singapore airlines and I’ll give them two thumbs up 👍 👍

I find it was a bit hot before take off. If there is a way to improve the airflow it would be great

Excellent service. I pre-ordered gluten intolerant meal and they handle it with care. They served me my meal before other people's to avoid crossed contamination. Thank you 🙏

No frills airline with minimal leg room and no entertainment

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

Very bad service and food variety will never come back again

My baby was with me it was really good experience with emirates

Fantastic as ever. Great staff super catering and excellent service.

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

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

The lounge staff at reception were inefficient and robotic. Boarding process was chaotic at the gate with no priority for business and first. At arrival into Dubai, no upper deck door . Food option and quality for this flight was awful . Thankfully the bar is always good.

Everything was superb, only bad point was that the fast track on London Heathrow arrivals was not handed out to me and I had to go back to the gate to collect it.

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

You can improve in many ways First the crew in general is good, but needs to work with passion to their works not like robots Second, collecting the ear headphones long time before landing is strange The crew should deal with the passengers with respect and descent way not like giving orders

My journey with Qatar Airways from Ahmedabad to Jacksonville on 3rd February 2026 was truly exceptional. The entire experience reflected comfort, care, and world-class service. Complimentary high-quality Wi-Fi throughout the journey was a welcome luxury, especially on a long-haul flight. The vegetarian meals were thoughtfully prepared, delicious, and served with attention to detail, along with a fine selection of snacks and beverages. What truly elevated the experience was the cabin crew — graceful, courteous, and genuinely attentive, delivering outstanding hospitality at every step. This journey perfectly showcased the premium standard Qatar Airways is known for, and it left a lasting impression. I would gladly fly with them again.

The boarding experience did not follow the Zones that were listed on the boarding passes. This was a two-level aircraft with many passengers. Because zones were not called out by the airline staff, there was simply a mob trying to board and it was not a pleasant experience.

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

Check in desk people constrained by fear. Obvious typo on Uganda visa, even though approved, caused loss of flight. Something is definitely wrong with this system.

Good staff, good intent, decent entertainment. More seat space would always be of benefit

Better service is needed. I booked for Qatar but I was switched to American way after I bought my tickets.

need to improve management and air hostess services. Rest of it’s OK.

some sections of airport are too cramped. The screening of luggage was twice and a huge hassle. They kept saying my boarding the for my next flight was in 10 minutes but were dragging the screening too long. having a 2 hour connecting time with this much delays in screenings is not good. They could see I was traveling with special needs kid yet I was" randomly chosen" to be personally screened again.

Qatar said few times that the luggage will be at the final destination but they were wrong. Please check where your port of entry is at the destination. This is where the luggage would be. The food was terrible.

I lost my baggage and it’s been three days didn’t able to find out. Also ticket was issued for qatar airways but they ended up board me on to Indigo from Doha to Hyderabad. My trip made miserable without cloths.

Air hostesses were great. Food was good. Flat bed is not that flat or comfortable.

Limit the number of usage of wine or please arrange our seats. The passenger was drunk on this flight and not on Thiruvananthapuram to Abudhabi.

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

I paid 44 $ for seat upgrade (22D) and my seat was stack in high position for all the 6 hours of flight. I don't recommend the upgrade. I am looking to get my upgrade payment back

More leg space than other flights, but felt like *maybe* narrower seats?

In Colombo when I-drop my baggage Sri Lanka air line crew not polite way talk very rude

Same problem place in the middle so small Im 1,85 m so not good 👍

The staff was kind and polite, but it was very very hot and no ways to have some fresh air.it would be also be nice to have more time to sleep, since it was a night flight

Food and beverage service have rooms for improvement .there were no entertainment facilities available

Check in was quick and gentleman was very nice and friendly, during flight crew members were polite and attentive, food wasn’t as it should’ve been. Entertainment section needed to be updated i.e add new movies

The worst experience with British airways that left me with a delayed flight until the next day and no hotel accommodations available or food voucher. I still have had anyone follow up on this matter

Always the same, boarding starts before the plane is ready so we were all standing in the sun and 36 degree heat on the tarmac. Once in London, packed like sardines in busses to the terminal. BA have a way of making you feel like they dont want you as a customer.

We boarded late, sat on the plane for 45 minutes, I was sweating on the plane and there was a child that screamed and kicked my seat almost the entire flight. The parent nor the crew would do anything about it. Food was very good.

The crew member of my cabin was excellent. The flight was delayed due to air traffic in London. I worried about my connection. The flight attendant eased my worry with prompt updates on the current flight status, as well as helping me log on to BA.com to find out the exact gate info for the next flight. Truly appreciated his help.

Meh. Lived the seat. The entertainment unit did not work and had to be reset 3 times. Service was SLOW taking over 90 min to be served. Crew forgot about my meal. Chicken was dry and almost inedible.

There was an older steward, he is top notch. He is very attentive at the passengers. I do not know his name. Thank you to him.

Good was great. Some of the older crew were grumpy and not customer friendly.

Bad. After 3 hours on tarmac, flight got cancelled. No assistance whatsoever from BA.

Much better than from Singapore to London, which was awful. London to ORD was business class experience expected. Friendly and helpful flight attendants, decent main course, delicious dessert, comfortable lay flat private seats.

The "new" configuration Club class provides a fantastic experience - a private pod, with great design and plenty of room to spread out. In addition, the cabin service was beyond excellent, and the food was great. Thank you for this sector, BA - it was worth every penny.
