I put the review all together for the first review

I liked that they gave us a couple of meals and drinks but the meal was not good and not many options especially if we are seated in the back of the plane.

Again on this leg the WiFi wouldn't work. The seats were comfortable with adequate cushion and space between seats for my legs. Very nice 3-hour flight.

Everything was great, however the seats in the back are very small. Not as Comfortable as I would have liked.

Excellent food. Good service. Crammed Premium Economy seats. I Asked to change seats during check in. They told me the flight was fully booked. But on board I saw empty seats where I could have been easily relocated.

Good. Please add a non- applicable category to your questions.

Amazing crew, excellent food, business class seats seem a bit dated but are super comfy even for a very tall person. If continuing onto Taipei, the stopover in Bangkok is a bit annoying (queue at security) though the lounge is decent.

Boarding is fast and easy for economy class, food was ok baggage policies are good

Everything was fantastic! It was a short flight but the crew really went above and beyond to make it a great flight. I felt cared for with EVA.

Delayed due to no fault of flight crew. Efficient and worked well together.

Really great service throughout and the food was really nice. I can highly recommend thank you very much.

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.

No frills airline with minimal leg room and no entertainment

Service excellent would chose Singapore airlines as my first choice

A 16 hour flight from Singapore to Los Angeles had only 2 meals. It would be great to have 3 meals.

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

Transfer within the same terminal and lots of facilities at the airport.

The male traveller seated in the row in front diagonally opposite my husbands seat across the aisle as soon as the seatbelt sign went off moved across the aisle into the seat in front of my husband for the entire journey from London to Singapore he had his seat reclined and pushed back and the seat touching my husbands knees for the entire journey from London to Singapore. very uncomfortable for my husband.

Airport lounge for business class is too crowded and not comfortable. Poor foods and facilities. Boarding was delayed. A lot of coughing people in the flight even in the business class, which indicated poor screening and health risks.

More Baggage limit Alternative of virtual check in at airport , prefer personal touch with “real person”check in counter for baggage drop

We still get drinks and a snack. Love the gift bags too.

Excellent airline. The plane was clean and the staff were very attentive

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

Except that our flight was cancelled, by mail, and later moved to 12 hours prior, then the experience was good. In Bangkok we were offered a hotel, it was fine, but would have been nice to know in advance😉

Although booked meal of fruit only The crew had not received this special meal The same happened on my flight Bangkok / CAN The films are so old that best is to use own computer to watch downloads . Serve nuts but they do not warm up . Service is attentive , WC clean

The boarding efficiency was good. A couple of the flight attendants did not seem in the best of moods. Overall it was a good experience.

Delayed flight in Singapore caused the transfer at Bangkok to be very stressful. Fortunately, no elderly were in this trip, else it will not be possible to catch the connecting flight. There were also several occasions throughout the flight journey where some of the passengers were not wearing their seat belts despite several remainders from the stewardess.

Check in was a disaster. 90 minutes and only 2 economy check in desks open. Had to rush to catch the flight.

I couldnt go on this flight and lost all my money over 1,000 UK Pounds as my visa to Myanmar was not accepted :(

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.

I prebooked a comfort plus seat on this flight and therefore the flight was comfy. I got the correct seat in the correct section of the plane that I have booked, that's this. Flight was comfortable. Staff were average on the flight, appearing to be rushed and short in engagement with travellers, perhaps this to maximise there rest time on the flight.

Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

Staff was very friendly. There is no on board entertainment, but it’s such a short flight that it doesn’t matter. We also got a meal which was nice and unexpected due to the length of the flight.

Flight was fine overall. What you would expect from economy seats. I did appreciate the amenities (eyemask, earplugs, small toothbrush and toothpaste, thin socks).

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

I staff or crew they were very friendly and humbly, they done theirs service very well, I appreciate them and thank you to the company or Qatar 🇶🇦 Government for providing as good service in their flight ,once again, thank you 😊 🙏 😀 😉 👍

Crews are very rude and unhelpful. Cramped seats in economy. Foods are useless

Lovely aircraft and I flight entertainment. Good leg room. Full flight crew struggled a bit

Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats were comfortable, but boarding was the worst I've ever seen. Way too much walking to get onboard as we had to go up & down steps several & then bus took us halfway around the airport for boarding & had to board outside after a very long bus rood.

I will never want to book with these people. They are arrogant and rude. Food was really really bad, crew was even worst

The plane was so old, it needs to be retired! The windows were rattling we paid for premier economy and there was no footrest. Video console was so old, barely had any games for kids. Video console is very slow to react. The gaming console was broken. The foldable food table was sticky and the air hostess had a rough time opening it and closing it for us!!

Generally very good. I think their service is better than some other big names I used to travel with. Their food variety is second to none - and you can place order beforehand. Their seating design is a bit awkward for service, I'd say. Flight attendants must be tall enough - long legs and arms - to reach the window seat passenger while crossing over the isle passenger. Also appreciated the variety on entertainment.

Could have used more leg room for “business class” which is basically coach with a middle seat blocked. Crew was friendly, attentive. Zero entertainment.

Generally okay. Disappointing compared to some of their competitors. My seat hadn’t been cleaned properly which was upsetting

Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.

It’s the old style plane with the old Ying Yang seats doesn’t compare to other airlines with newer planes.
