Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

Similar to Hyd->Dubai this too was worst airlines. Bad seats, bad seating arrangement which created lot of confusion since family member were not given seat together. However most of them changed the seat and got with the family. Cheap tactics by Emirates.

They should resume the fast track for business / first class passengers

It was great, a little more leg room would have been better particularly since we were in premium economy

The plane seemed pretty old and the food was not good

Flight was delayed by and hour but were informed beforehand

Ticket price is competitive, flight time is punctual, aircraft cabin is clean, food is average. Can improve on serving system of meals on a A380 airbus. I had only 15 min to eat my meal. There are lots of people to serve & took a while for food to make it down to my row.

Flight was on time. Seats (economy) were very comfortable and food was excellent. The bad thing was that after landing it took an hour to reach arrivals. We had to wait 15mins to get off the plane and then had to board a bus which moved very slowly and took almost 30 minutes.

On this flight, about the last 2 hours the captain kept the cabin too hot. It appeared like the ac was off.

The ground staff on Islamabad is horrible. The on board services are excellent.

I was in a middle seat where I felt a bit too cramped otherwise the trip was good

The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.

The staff on the plane were attentive and friendly. The frustration with the cabin crew was that we were served second to special diet people. And, we were in economy section. The boarding staff was mediocre. Got scolded for requesting to sit with spouse on 14 hours long flight home. Was told they cannot break up families for us. Didn’t understand how we were denied sitting together as we are husband and wife. After many words of exchange, we were accommodated. Cleaning crew did a horrible job! Bathrooms were unsanitary or dirty from beginning of flight! Didn’t expect sparkling as its economy, but did except decent.

Food from Surabaya was below average but from Singapore is much better

The usual excellent experience with Singapore Airlines. The airplane was on time and actually early to Haneda Airport. The onboarding experience was pleasant with no delays, perhaps owing to the fact that the flight was not full. Nevertheless, the air crew were their usual outstanding standards in serving the passengers.

Good service and food. For buying items on flight should be preordered as they don’t keep much stock on board.

Excelent service and plenty of food and drinks during the flight. Flight crew very attentive to our needs. Leg room between rows are very disappointing.

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

It was very good experience on board to Sydney with SQ.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

they ran out of fruit for breakfast and so I just had a yogurt instead. other than that the flight was good

One of the best Qantas business flights I've had. Quality product

Great as usual, some delays but well communicated and made up for in the air

We were upgraded and after just a short delay in attending to a safety check we were on our way. Would definately fly Qantas International on their Dreamliner again.

Five hour flight instead of four hours due to westerly headwinds which wasn’t the fault of Qantas !

I tried to check in online but was unable to do so. I stood in line for nearly two hours to check in. American Airlines was understaffed. When I finally got to the kiosk to check in, I was still unable to check in. No AA staff was available to help. Finally one of the airport security agents who was helping passengers became of lack of AA Staff told me: “I think the reason you can’t check in is that you are starting your name with an upper case letter when you write it. Just write it with all lower case letters.” That did allow me to check in. HOW COULD ANYONE POSSIBLY KNOW THAT IF THEY USE AN INITIAL UPPER CASE LETTER TO SPELL THEIR OWN NAME, AA WOULD NOT ALLOW THEM TO CHECK IN?????? Then I had to wait in line over half an hour again to drop off my baggage. Although I arrived at the airport 3 hours early, by the time I got to the gate, they had already started boarding.

The wifi was out. Otherwise it was great flight. Richard, as CSM, was excellent.

Inflight entertainment, poor that there are no headrest screens on aircraft used for an international flight.

The Emerits/Qantas flight was cancelled to Wellington. We need a refund. Had to buy another airline ticket. How do we get the refund. Still not in Wellington.

Their aircraft are old and amenities lack way behind other international carriers leaving from BNE. Even in economy

Even though I paid extra for more room, we were very cramped and the seats were hard. Also, when we checked in they did not post the gate we were to arrive at even though we were half an hour away from boarding. The agent did not know either. Actually, the flight from Porto to Zurich did to have the gate posted, and there were very few agents in the boarding areas who could help us. I would never fly Swiss Air again.

The flight did not take place because the flight was canceled and I still have not received a refund for the flight.

The cabin was warm and few used the blankets. I should’ve upgraded.

The plan was delayed for takeoff by an hour, but we ended up making the landing on time which was a nice surprise.

Delay more than hour created pressure to catch the connecting flight

The seats were so close together, when the man in front of me put his seat back, the screen in front of me was 9 inches from my face. There is no way to lean forward if I needed to pick something up. It was pretty uncomfortable for a ten hour flight. I was very surprised.

The food was good. Most the staff was pleasant. The flight would be drastically improved with WiFi on a long international flight.

The crew was very friendly and nice! Very smooth flight.

The whole experience was positive. Crew very friendly and helpful. Very greedy with pre-seat allocation. Web site too complicated

The meal was wonderful and strawberry ice cream was a plus.

The flight was good. It arrived at Heathrow on time but then there was no transport to take us to the terminal. We sat on the plane for an hour waiting for a bus. I will avoid Heathrow if possible in future. The crew were very apologetic.

we had to walk up stairs to get into the plane--no jetways. Perhaps that's a problem not with the airline but with facilities at Heathrow, Glasgow, and Edinburgh. But it was inconvenient.

The seating has become ridiculous… like a contest to see how narrow and short they can be made- forcing anyone over 5’1 to pay more to not be twisting oneself into a pretzel. Really insane- would have thought BA was better than this. Frankly- it cancels out a lot of the positive aspects.

flight was delayed from BWI to London - missed my connecting flight & then connecting flight (also British Air) was delayed - food is awful, TV & movie selection is great

The flight was fine but they made me pay for my carryon bag because they said it was too big at the counter. But it fit under the seat just fine.

Super tight economy class. My knees were hitting the back of seat in front of me (I'm only 5'6"). My small backpack (sized according to their required dimensions) would not fit under the seat in front of me because there is a box (is that the life jacket?) in the way. Over all, extremely uncomfortable. I forgive the tasteless food, but the tight seating was torture

Excellent service by the flight crew, and the food was relatively very good compared to other airlines.

Flight was excellent, staff was great. My first time in first class and it was very relaxing and comfortable.

They can separate the young children from people who want to have a rest. It had lots of crying and loud noises from the children.

I had an awful experience with British Airways as they broke the handle of my checked in suitcase and when I went to complain they told me that this was not their responsibility. This has to be one horrible airline that does not take responsibility for the damage that they have created
