Wonderful service, planes and interior in great condition, very pleasant experience

Wonderful service, planes and interior in great condition, very pleasant experience

Every thing was fine. Some ild classical Hindi movies should be add

The premium economy seats were not that great. It could have been more premium than economy seats.

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

The singapore airline now compared before covid, I like the service before covid. SQ was the best of all airlines but now I am going to look for different airline if I am travelling in asia.

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

They close their counter so early. I had internet issues so I couldn’t check In online . I would have made the flight but their counter was closed 5 minutes before we arrived. No way of contacting them even though I had the confirmation number and tried to check in the night before on someone else’s phone. I tried calling their customer service with no pick up. Horrible experience, I’m very unhappy with them. I hope to never fly with them ever again. It costed me almost $900.

Even though it was a very full flight, the service was still excellent, the plane did not feel too cramped and cabin crew made a sincere effort to help passengers find overhead space for stowing luggage.

I did not like anything. Flight experience was bad overall.

The stewardess was very helpful all the way. My seat had an issue with headphones and after the replaced and gave me a new pair and noticed it was the seat I got a new chair to sit and a great ride back home

Overall a good experience, the flight was on time, the crew very attentive and friendly. However the seats are too cramped, there is no space, and as soon as the person in front reclines the seat, it's literally in your face.

We so appreciated that our connecting flight waited for 6 of us!!!

Delay on take if- short connecting time- was supposed to have a wheelchair to connecting flight- limped with a cane thru the airport to make a connection

Swiss Air rerouted me at the last minute and lost my luggage. At this time they still have not been able to locate it.

A lot of things could have been better. They lost our luggage. We missed our connection from YVR to Naples when we arrived in Zurich and then we got re-routed to Rome and then Naples. We eventually got to Naples but our bags didn’t. Our experience at the lost luggage in the Naples was not at all reassuring. They didn’t seem that interested in our problem. I did a live chat with Swiss customer service and all they could do is tell me to follow the process. Meanwhile we’ve had to spend significant money on clothes and I have to replace medications. This has meant our trip so far has been totally different than what we had planned. It’s not clear that our baggage will ever show up which means we will have lost significant amount of clothing and other things and our two month trip to Europe will have more problems than good memories. So far we are not happy.

The flight was canceled so it’s stupid to send me this now !!!!!

Missed connecting train since flight was late into Zurich and I had to stay at airport hotel because of it as well as I had to repurchase train ticket

Pros: "Not much"
Cons: "During COVID there was little attempt to distance passengers during security checks, boarding and onboard. Crew did not inforce mask policy. Fellow passengers were inconsiderate, loud, littered just throwing food wrappers and trash on the ground - crew did nothing."
Cons: "I fell sick and my doctor advised against flying. Tried calling Swiss Air and JustFly.com: 6 calls back and forth and 7 hours on hold, no help. Finally got advised on driving to the airport to make the flight change at the Swiss Air counter at O’Hare. The representative told me to bring a note from doctor to switch flights. I did the next day. The same representative looked me in the eye after advising the day before and said there’s nothing she could do. Why make an elderly sick person drive to the airport again if you know already you cannot help??Absolutely terrible experience, no help from the airline or travel agency. Total loss of the full price of the ticket."
Cons: "Too much nonsense with carry on and check in language. I paid for my seat but they changed it for better balance of the plain. Really I weigh 165 lbs. Once the plane reaches altitude they let me take my seat. However the plane was barely occupied and somebody with closer and took my seat."

Finnair cancelled my flight 12 hours prior to leaving for Helsinki. They stated there were mechanical problems. I had to scurry around to find a new flight that would meet my needs for arrival in Helsinki. Luckily I was able to find alternate transportation through Lufthansa/United.

I’m very disappointed, to fly into an airplane for 10 straight hours, and not having a TV even though when I put the ticket I was told that I will have entertainment for the TV. Very disappointed.

Helpful steward. Allowed me to move to some empty seats and I was able to get some sleep. He also had milk for my tea. Americans don’t realise that cream or half and half ruin tea.

Security was a mess at the Helsinki Airport. But I was delighted by the connecting flight waiting for us for JFK.

The crew was very good, excellent, they help me with my needs.! Food was not that good.

Everything was quite easy from boarding to landing - the staff was great and service was excellent too!

Flights are standard. But being over 3 hours late is too much.

In-flight entertainment was. It working for the entire 12 hour flight! Unbelievable! At least provide free wi-fi so people could use their phones.

The flight was surprisingly good, especially given initial experience. BA app is horrible as is their customer service. Online check in was a horrendous experience and when I phoned their customer service number, the live agent with whom I spoke was rude and dismissive. She did helpfully inform me that their IT people were working on a known problem related to online checkin. However, once she delivered that information, she curtly ended the call before I could suggest that since BA was aware of this, it should be posted on the app and online. I grudgingly flew BA this time - have avoided them for years because of past similar serial bad experiences. While this flight was fine, I’ll return to avoiding them in the future given the hassle experienced and rude personnel.

Boarding was a shambles, with no proper line or queue and multiple groups joining at the same time. Overhead space was limited. Seat spacing (width) is not generous. My neighbour was invading my space, before he even spilt his drinks over me (twice!) as he struggled to contain his meal on the table. The main meal was very poor. Choice was simply chicken / turkey - the crew didn't know exactly which - or vegetarian. The chicken meal was really poor quality - uninspiring and tasteless; and very little offering of drinks. Half the crew were friendly, half really need to cheer up.

They shld provide food. Between food they are giving 10 hours gap which is toooo much

Was required to print a boarding pass, which I'd prefer to avoid. Seat (economy x) was comfortable, service was excellent.

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

The business class experience was awesome - I will be using QATAR airways again and it'll be business class again - appreciate the privileges afforded to the business class clients - thank you.

Food and Service inside the flight. Airport service from Qatar is not good mainly because of lack of coordination and not used of seeing so many ppl commuting

It was the terrific, I was promoted to businessman class, and the service was amazing.

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

Not so good. Issues with seat assignments, unruly lines during check-in, half a sandwich on an international flight. I was originally supposed to be on Qatar airways, but it was switched to Indigo after I bought my tickets. They wouldn't even let me get seat assignments from the US to Mumbai. I was automatically assigned seats, and a middle one at that. Terrible.

Boarding process was terrible. Will not travel Qatar Airways if I had an alternative. The food was one of the worst, even for airline food.

Fine. Don’t think I would fly with them again

I sat in the last row of seats. On an 8 hour flight they allowed folks to stand and talk and drink in the back area near the toilets the whole time. They were at times loud and in the way. It was a little annoying. The crew on this trip were pretty mediocre and the plane was littered with trash when we disembarked.

I didn’t get to London or Amsterdam. They lost my connection flight . I was stuck in Madrid and they rerouted my flight to Austria where my son had to come and pick me up. To get to my destination and they lost my luggage and they’ve told me they can not find it very poor service so have no word for what happened

Boarding process needs to be improved. Business class passengers were told to stand in the economy line and vice versa.

Overall good, but the fact that there was no WiFi was a big deal for me. I am not used to having no WiFi during long flights. I always fly Delta-KLM and they never have had an issue with WiFi.

I asked for a wheelchair. I have a back health condition. I had to walk a lot

I travelled on biz class and f there is no water in the toilette to wash my hands I would expect to have this indicated somehow and not just finding out when I'm there expecting to be able to wash my hands and teeth. Also this is in general that it is always so rushy at the end of these kind of long flights. It is like we are sitting there for 9 hours and the last 1.5 hours just feels like I have time for nothing. Because food comes and at the same time we are close to destination everyone tries to pack their stuff and go to toilette and eat and everything :))) not that like I would know a good solution here I just wanted to raise this :)

Boarding = No one respected the boarding groups. The ground crew did nothing to enforce the boarding system. What is the point of being a Gold member when there are no benefits to that? Tired old plane

Almost 3 hour delay. First because the crew was late. Then a technical problem with the airplane.

Emergency row seat less comfortable than promoted. Restricted by emergency life raft storage.

Better communication to those connecting flights and have a customer care desk at the airports
