Airline reviews

I had ordered vegetarian food. What I was presented was extremely dissatisfying and not up to the mark. I pretty much did not eat entire 19 hours. For.an airline voted as best in business, it was extremely disappointing. Seats were not comfortable to sleep. Entertainment system didn’t have much choice. WiFi didn’t work for more than half the time. Cabin crew were also difficult to understand. A bit of diversity like Emirates crew would go a long way.

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.

The flight arrived on time. 2×2 seating meant no one needed to sit in the middle. This was a connectibf flight from Singapore and required going to 3 counters in different levels to check a golf bag

Pleasant business class flight experience with good onboarding experience. Flight service team was excellent with usual book-the-chef menu available

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

My groups frequent flyer star allianceUnited airline miles was not accepted. The Singapore premium economy bag had to be requested, it was very lacking- no toothbrush. I paid more than double than economy but could only use the bathrooms sharing with economy which was hardly available and had to wait in line. Is the 2X $ worth it just for a larger seat???? It is questionable. Seats were not that comfortable. My husband’s seat had white stains on it- had to wipe it down. Our headphones did not have covers on it. Food- way too much.

Crews are not allowed to perform any service whenever the captain deems there’s a chance of turbulence. Even if it is perfectly smooth air.

plus: service and personal assistance minus: online check-in did not work

I requested an aisle seat and got a middle seat The flight gate was changed and the flight was delayed

I didn’t get to go, and no refund was available after asking for 2 months

Old 777 on this route uncomfortable and in need of updating.

Frankfurt airport was awful! Brand new airport with modern technology but a process that does not keep up at all. Attitude of staff at the airport also disgraceful but that is normal in Germany. One security gate in the middle of Monday and machine clearly not working well. Immigration has 2 staff with serious attitude.

On time, organized boarding, good food and entertainment-plane was clean, comfortable, well-maintained and updated.

Difficult to find some food option for gluten and dairy allergy. May be a fruit salad would be better

The food options were excellent for Economy. It was difficult to find the lounge after clearing security and boarding was clunky

The service was excellent. We flew coach on this leg of our trip and it was still very pleasant.

The first class experience was great but Frankfurt airport is very confusing. Badly signed all round. Boarding was not pleasant and check in staff was arrogant.

Flights were both delayed. No luggage on arrival for the whole plane and no contact since submitting a PIR.

Flight never took off. Boarded after multiple 30 minutes interval delays for hours.. then after an hour onboard, captain announce cancellation and back on the bus to the terminal with no information and everyone to fend for self.. Emirates did absolutely nothing to communicate either electronically or announcement. It’s unprecedented I know with the flood but lack of communication creates anxiety and extra pain for staff. Emirates should do better.. no supervisors monitoring floor and passengers abusing them which isn’t right but should Have had supervisors monitoring

Everything was perfect except boarding . Have to wait @ gate for 45 minutes after announcing boarding ..

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.

Gate and boarding processes were handled smoothly and efficiently. Both (connecting) flights departed and arrived on time. The cabin crew seemed anxious and a bit stressed/rushed. Food service was OK, but the hot food dishes were poor quality.

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.

USB charging port was not working at my seat 48K.

Always liked Thai Airways but in the past they have been very expensive, not being a millionaire just yet, I will use cheaper airlines. Bangkok to London £370 11 hours 45 mins. Old plane but ok. Lovely ladies on board, very polite. Food was ok. Will always use them if the price is right.

The aircraft was really old, the staff demotivated and the overall United airline service is horrible

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

food poor i said chiken i got pack a pow breakfast lousey .job to explain wot it was ...

After going back and forth with the airline, they never reimbursed the airline tickets. Went around asking multiple people how to get reimbursed and kept getting put back, not satisfied with their customer service.

Boarding and deviating was mediocre. At boarding they have not prioritized Business class. During debarking they prioritized premium economy. Also bus rides both times.

The vietnam airlines app was not able to allow checkin with the confirmation nor with the ticket number. This led to quite a bit of consternation. Speaking with a colleague from Hanoi, he did tell me that their app is not the best. It may be best to inform travelers to only use the link and to plan on checking in at the airport for this airline. The check-in was very easy and the staff were excellent.

The aircraft was little tired but the food and service was outstanding

This was our fourth domestic flight with Vietnam Airlines, and once again we found the experience very suitable. Check-in was easy and efficient. They did take our carry-on luggage, but that was fine. I’m actually happy not to deal with it on such a short flight. The flight was just over an hour, departed on time, and we climbed above the clouds into a beautiful sunset. Even on such a short flight, they served water, which we appreciated. Luggage came out into carousel in Nha Trang in good time and off we went to meet our GRAB. Also, Vietnam Airlines have easy to locate ground level offices in cities and towns where you can get assistance with staff. I liked this service as we did go visit one in Nha Trang. We would definitely recommend Vietnam Airlines and wouldn’t hesitate to fly with them again.

Lovely staff, comfortable seats. Transit time was short but they had great processes in place to get us on the plane.

For a domestic flight, seats are ok, but fir us as tall dutchies, the legroom is too small. However, for a short and affordable flight, is not a big problem. Staff is still very nice and a complementary water very welcome.

2 hours delay, time changes started already 2 days before the flight

An excellent airline; polite and courteous cabin crew, excellent meal and drink service. Highly recommended.

when we arrived at Taipei no one help us to get boarding pass. we saw a few people there asked them for help but they just ignored us. There was a guy told us to call Starlux number to get help but we don’t know how to dial the number until there was a lady working there helped us to call Starlux customer then someone came down took us to another counter for boarding pass. Very confused and inconvenient. We might not choose Starlux again in the future.

Flight was good but they cancelled return direct flight so they provide us connecting flight through hanoi

That was the last time I booked Kayak. The connecting flight got canceled and the trouble shooting terrible. Next times, I will book the airlines directly. Good bye

I want to highlight the crew members and their excellent work and professionalism. They work hard to make a long trip the most comfortable as possible, the food and drinks they offer are pretty good. And they are always asking if you need something else. I have had experiences with other airlines where you have to basically beg for a bottle of water. This is not the case. Highly recommended!!!

Way too crampled. Charge more and put in less seats.

I was first assigned a seat that could not recline fully and was at the back of the craft. I was not able to select another seat during check-in even when opting to pay for selecting a different seat. I had to contact the airline and spent 25min with a chatbot and was then transferred to an agent who was very helpful and could change my seat (free of charge). The entire process took me one hour. If I happened to not have that hour available this would have been a problem. And that was only to check in. The next problem is that the airport lounge I had access to is located landside. How strange. So it means that you need to allow time for security check and passport control and boarding time when leaving the lounge, which makes it almost pointless having lounge access unless you have a very long layover or arrive 5 hours before the flight. Inflight service was okay. But not up to par with the likes of QA, SQ or CX, even though the price is the same or even more. It was much better than the domestic flight where Lufthansa is actually a low-cost airline with legacy airline prices.

The seats on Lufthansa’s international business class on the A350-900 is the worst product in the market. Our chief purser was AMAZING though. She is the best FA I have had in many years.

One of the best airliner in the world But airport was very poor

Very bad 3 times change the gate and too much delay...

the blanket was great and pillow helped. really need a toothpick packed with meals

This was the worst flight of my life. Economy seat directly behind a premium economy seat with extra recline meant I have about 6 inches between my face and their chair. My seat would not recline at all. I couldn't even use my laptop on the tray table because I had so little room. I was in a casket basically for 10 hours. Completely unacceptable.

Very comfortable plane. The food was very good (for airplane food). The crew was great
