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.

It was all good. Lovely attention by the crew. I lost my glasses but they did everything and eventually found them. They clean the toilets regularly which is a big plus for me.

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

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

Delayed for an hour. No announcement by the pilot. Cabin is very busy because it’s narrow-body.

There was no screens on the flight, and no wifi with which we could connect to the internet and stream any content. This was a smaller plan so the business class seats were a bit tight. No hot towels or welcome drinks like when you fly on the bigger TG on the same route. The food was excellent, much better than the previous Thai airways business class meals. It was also nice that they offered eye masks for easy sleeping.

Excellent service in business class. Well worth the slightly higher fare as it includes lounge access, additional luggage weight and a full hot meal on board.

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😉

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 :(

old aircraft, some of the crew are not polite. I chose my seat to be window and I found it with no window and the seat was not operating...!!!

Very lovely aircraft and crew. Seats were comfortable and the food was great and served swiftly. Delayed flight due to a passenger coming off the flight but overall a great experience

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 😊 🙏 😀 😉 👍

My inflight entertainment unit was not working. The chair compartments were broken. The suite door would not latch. Given the cost of the total ticket, I was extremely disappointed in the service. The flight crew was not very helpful.

7 hours is a very long flight - the crew was ever present and helpful. The cabin was comfortable - WiFi was a disaster as was the entire entertainment and flight info system. They could have helped passengers by explaining that the information available on our screens and our continued attempts to entertain ourselves with our phones would be in vain. Other than that - all was well! Very comfortable seats, amenities galore and lots of crew attention. They might have benefitted from more crew as very few served the premium and basic economy,

The boarding area was crowded with inadequate seating. Flight delayed which made it uncomfortable.

My baggage (1) didn’t arrive with me. I am waiting for it.

Terrible we had to wait out in the cold for transfer bus to take us to the plane. Once we finally got on the plane seat had no cushioning not comfortable at all. Food was overcooked and dried out. I was skipped over when they served drinks I had to call them back to give me a drink with my food. Overall terrible experience this time. I have used BA before and never experienced service like this before. If this keeps up I will look for other options

Heathrow Airport - a nightmare. BA flight, expensive for no other reason than the flight was full. So they will at least be happy. Departed late. Aircrew got the job done, but attendant responded to my question regarding purchase currency sarcastically. Comfort OK entertainment system OK, Landing time ahead slightly so well done pilot. Overall mediocre to OK but I'll fly from Gatwick next time!

My experience on this flight was good. The seat I had had a lot of leg room, but it was so close to the aisle that the flight attendants kept bumping into my visual monitor connected to my seat to watch tv.

It was fine, but it cost me twice as much to return to Boston as it took me to get to Heathrow from Boston two weeks prior. I flew on Jet Blue over and it was half the cost of British Air.

Staff and comfort were great but first choice meal was unavailable even in row 21.

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