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.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

Due to the delay of my first flight, my connecting flight with JetBlue was canceled by Singapore Airlines, but the JetBlue crew was very accommodating and rebooked a seat for me. The crew was very nice and had good attitude.

Left hr late & arrived 1hr late luggage was slow to be offloaded! The flight crew & food were good! Movie selection was ok!

We started with a 2 hour delay due to some airplane technical issues, and while we got a little snack pack, it was a pretty long delay for SQ. The flight itself was short, there's no entertainment on the B737-800 and there's a small snack. Functional.

Flight attendants seemed a little more stressed out than in past Singapore flights. Not sure if that was because we had a completely full flight or if it was because it was just before Christmas. Food was decent but someone needs to update their Indian Vegetarian menus to ensure more variety, less duplication of items (Parathas included in2 different formats) and less dairy.

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.

I cancelled my family 2023 international vacation because you guys double booked me with the same date, passengers, airlines and just hours difference and did not want to refund me at the right time and then finally cancelled the extra booking! Cancelling the booking that I personally booked! And you guys kept the unauthorized booking! This experience was really bad! Ruined everything! Never again I will book with kayak , me , my family , my friends and most importantly I will advocate to everyone to make sure not to book with Kayak! None existing customers service! Only 3rd provider that serve only their company and not the travelers!!!!!!

Wuhan - Dubai. Old plane: 1. Only USB charger. No power outlet to plug in.. 2. Super narrow seat layout 3. Toilet cover consistently fell down and hit my back when sitting on it.. :( 4. Entertainment system touch screen not sensitive, and need to press hard or use finger tips to hit. Crew were very nice and accommodating though.

1. I got very poor check in experience with the counter lady . This is the first airline I ever experienced that no combine check in weight allow . Even we have 4 of us but weight counter by piece . So we wasted lot of time argue and repack . This is super crazy 2. Next I left my Samsung tablet on the plane . And I started to escalate and finally spoke to southern airline lost and found in Malaysia and the amazing answer she give is : system nothing found and please try to call southern airline in china 🧐 . I have been flying many other airlines but this is my first encounterment with such irresponsible airline response and no empathy given to customer . My feeling is nobody bother whether how customer like me feel and I’m just too small for the management to take note .

No red vine, no whiskey, no vodka. No that I wanted all of them at once but still...

During flight, some passengers perform stomping leg exercises which disturb the comfort (I.e. sleep) of other passengers.

Traveling with the Chinese airlines , their service superior to the US Airlines , they are much more friendly and the seats are comfortable , In the past I flew with United , now ,United Airline will become history for me .

Pros: "Yes, seats were very comfortable and crew members were extremely helpful"
Cons: "Everything was excellent."
Pros: "No..no redeeming features.."
Cons: "Coffee was the worst I've ever had. The 2+1 powdered mil and coffee stick. Truly awful. But i suppose there aren't many people on the flight who would order coffee..I would even pay extra for a coffee if they had a quality option. Food is comparable to a school canteen. I would probably pay 20rmb for this in Shanghai. Frozen butter for the half-frozen bread. They really couldn't do worse..."
Pros: "Seat was great. Bedding good."
Cons: "Meal service was rushed with all courses being delivered literally one after the other."
Pros: "The food was great--and a customer service agent helped me make a short transfer, walking me from gate to gate."
Cons: "I was not able to check in on line the night before, which made me anxious."
Pros: "Seat was comfortable and it was a huge plane there was little delay on order such as water or any thing."
Cons: "Service inside the plane by the crew members!!"

It's only a short trip from Sydney to Melbourne, which i have done many times. The trip met my expectations

I really appreciated the fact that when I checked my bags at the Quantas counter after arriving from an international flight an hour early, the agent noticed I had a very long layover. He then found an earlier flight that allowed me to get to Cairns several hours earlier than I planned. That was amazing because I had already traveled over 20 hours and wasn’t looking forward to such a long layover. It allowed me to see my daughter and grandchildren much earlier (it had been two years since I visited last).

Qantas cancelled my flight for no good reason and rebooked me into a middle seat.

The flight met my expectations. It left and landed on time

Everything as good as can be if one flies economy bit not enough toilets!! People were queuing during the whole flight - there are really not enough toilets!!!

Flights delayed multiple times, travellers requests for updates ignored. Qantas continues to desatisfy travelling basics.

They actually held the plane for a few minutes and had someone at the escalators from Qantas checking to see if we were almost at the gate and radioed ahead to tell them that we were on our way. We called down to the person and gave her our names, coming as fast as we could.

Better food, hotter coffee, otherwise it was a very smooth and reasonably comfortable flight.

First time flying in Qantas. There is zero WiFi on the flight to/from Australia. Crew was great both routes - very attentive, personalized service. Pleasant staff throughout.

Packed flight. Urged to check carry-on before boarding only to discover numerous empty overhead bins after boarding. Challenging entertainment screen. After almost 20 minutes to arrive at baggage claim, waited over 30 mins before luggage was loaded on baggage claim carousel.

Gatwick London-Shanghai -Bangkok.. Would have liked entertainment screens, but I know these planes are not that new. Cheap flights at the time of booking, Emirates wanted double so you get what you paid for. I would fly again with them, but if Emirates was the same price I would go with them.

The landings were smooth . Being unable to check-in online was terribly stressful and the queue at Haneda exemely long. We paid extra for window seats and did not get them.

How do you run out of beer after one hour of a twelve hour flight?!

You’re in the three parts of my life, the China Eastern air crew remembered and wish me happy birthday. I was given pastries on two different occasions and a complementary drink. The stew is wish me happy birthday and gave me a birthday card. Everything was first class. Thank you.

Couldn’t fly since they wouldn’t issue a boarding ticket. Something to do with not taking the departing flight since it was cancelled due to weather. No notice or anything about the trip being invalid. The app made it seem like I was all good for it. Never trusting travel agency

I will never fly through China again. Maybe it was the mandatory retinal scan just to transfer to another flight or the complete set of fingerprints they require. There are many better and inexpensive flights to Asia if you look.

Cons: "delay of about 1 hour, we almost missed our international flight from beigin"
Pros: "It was a terrible, long and very crowded flight."
Cons: "The people/passengers. The whole flight felt like a budget airline. I am not looking forward to the return."
Pros: "The crew was very attentive and most good English"
Cons: "The food could have been better and there could have been a better selection of movies."
Cons: "Gate is crowded and no escalator only steps. No clear area for business class and its a fiasco boarding"

The flight was delayed numerous times with inconsistent updates and very ambiguous information. When it was finally cancelled the logistics of handing out vouchers and rebooking was extremely chaotic. Meal vouchers were completely inadequate for the airport restaurants, and not even accepted at some. All-in-all, it was a very disappointing experience.

Terrible. The flight from Islamabad to London took 3 hours more then previously planned, I missed my connection to Chicago, and instead had to go New York, spend an extra day before arriving at my final destination. The return leg of the journey was similar. The connection time in Qatar was shrinked to less then an hour unannounced, I had to scramble to barely make it to my flight to Islamabad. Terrible experience, never using British airways again.

TIRED OLD plane. Seat cushion is completely old and NOT cushion at all; after an hour of flying butt hurts. Boarding is a complete disaster. No one respects the boarding groups, and the BA boarding crew care less about boarding groups or Tier status. What is the point of spending all this money on Business Class tickets when no one respects the boarding system? It took 90 minutes since we landed to get our luggage. 20 minutes to show on the screen which belt we are supposed to go to and another 1 hour to get our luggage - not the kind of service you will expect from BA at LHR

The crew on this flight were attentive, efficient and friendly. It really made for an enjoyable flight.

They canceled my flight , they put me on a different flight that was delayed and the connection was lost . They lost my luggage. And now I’m stuck with any of my belongings.

4 hour technical delay. Cancelled second meal. Crew and flight were great.

British Airways canceled our plane and gave us a new flight scheduled to leave in only three hours, so we had to drop everything and rush to the airport. The new itinerary only left us a one hour layover in Madrid, which was too short because the plane landed late and so we missed our connecting flight. We were then booked onto a flight scheduled to take off 8 hours later, and were not given any compensation or remedial measures.

It took over an hour to check in my bag a there was just one person at the counter. Security lines for business class also took a while. Although I reported 3 hours before my flight I made it to the gate 20 mins before boarding. To add to that jewelry was removed from my checked in baggage. I am submitting a separate complaint to Mumbai airport for that.

Everything was great except for online checkin. That was through BA- glitchy and needed help on seat choice in person at the airport (and the staff were fantastic). Unclear if the problem is due to booking lower fare thru kayak vs directly with Finnair or BA but seems to be the norm.

Seat layout, flight/club attendant service, food variety and quality could have been better. Business class Standard is visibly low compared with 6 other airlines that we have traveled for the past two years.
