My experience with Scoot is very good. Will have no issue flying with Scoot again.

Great to have actual hot tastey meal on a flight. Well done

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

It was a great flight Food was great Crew was spectacular

They made me check my carry on even though there was room We un boarded in a strange way but overall it was good

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

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

Transfer within the same terminal and lots of facilities at the airport.

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

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

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 😊 🙏 😀 😉 👍

This is my first and last flight with Qatar because when we go for boarding pass in Delhi airport the team asked for money charging me for hand baggage which is technically including with my ticket so also we get one our temple pics I ask them to checking in but they tell me I have to pay $500 dollars for that additional which is not make sense than I diseased to throw away because I can’t take with us . For carry in beg also I pay some Indian n currency for the guy who help I already pay 6 passengers ticket cost me $8000 so really I’m not happy . PLUS MY 6 checked baggage was damaged I already claim for four beg at airport but now I’m worried about my stuff inside maybe broken too which is more expensive stuff me really bad experience

I liked the overall service and comfort. The only annoying thing was paying for excess baggage at the airport. They have limited options and they don't take all cards.

Boarding procedures are very tiring. We have to clear security twice for our connecting flights from Doha. Also every time we board flights we have to show boarding passes 5-6 times.

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

The staffs were very good and helpful especially since we were traveling with a toddler

Terrible airlines - suffered entire flight due to food poisoning from stale food

If you want to make money pls charge it in the ticket, Chennai check in crew simply forcing travelers make payment for unnecessary. Second, Chennai crew not even listening travelers request. Poor service and not sure you will improve with my feedback.

Lovely aircraft and I flight entertainment. Good leg room. Full flight crew struggled a bit

Service / food has to be much better. Staff were not very attentive to requests. Requested for a second serve of coke and got a weird look back from the host! Was also told they don’t have extra water bottles when I requested for one before sleep! Dinner time food was very minimum and average.

An overnight Doha to KL. Great sleep, good service and tasty food in business class

chaos boarding. Crew in business class seemed short staffed and lacking in attention to details initially, but did improve during flight.

The cabin was quite noisy as there were lots of children travelling for the school holidays. Found the selection of movies limited.

Delayed, not enough information. Had to ask for refreshments, crew could have been more proactive

The best so far coz this time it was all male steward on the economy cluster. They were polite, efficient & genuinely courteous. They do not judge you when you ask for more food & peanuts.

Delayed for 45 minutes. Don't know what's the issue. Other than that, food was not to my satisfaction. However it's okay.

My experience with the flight was okay. My experience checking in was absolutely terrible. I was told I needed to change my e-ticket number to check in because I missed my flight in PDX. Even when shown the itinerary, they didn't budge and sent me to KLM across the airport. KLM wasn't open until 8pm and my flight was at 7:30pm. Nobody made accommodations in any way to get me to KUL. To add insult to injury, they rescheduled my flight to the very next day, creating a very long layover and did not offer any hotel stay. After this, even worse, I found out later they delayed the first 7:30pm flight to 9:10pm. Meaning, I could have still boarded but they refused to even try to get me on the plane. As a result, I missed a day of work and lost pay for the day. Also, when I went to get my luggage, it wasn't there. It was STILL in Singapore. They had from 5:30pm to 5am to get my luggage onto the plane and they still couldn't get that right. This is the worst experience I've had flying anywhere in the past decade I've been travelling.

Orange juice change to mineral water . Should keep the orange juice.

Entertainment system was too old, crew were unorganised during boarding

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

Check-in very easy and smooth. Plane and crew were nice. Seat open next to me created more space. Food was fair but plentiful. Lots of movies and I was able to sleep some on the way to Munich. Very tight connection, about an hour. Fast through passport control and a bit of a walk to last G terminal gate but I made my connection to Palma. Unfortunately, my luggage did not make it. It is now almost 24 hours since I anded and still NO luggage. I know it landed last night on another flight. Local delivery should be today to my hotel in Palma but nothing yet. I asked about the tight connection when I checked in and was assured they would get my luggage to the connecting flight. Very disappointing it missed my flight but more disappointing that it has taken so long to arrive. Failure on the airlines and service to get my luggage to date.

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

Never flown with LH before so all in all wasba good experience. Also good to know that approx 24hrs prior the flight opens up for being able to organise the seating free.

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

Great flight. Left on time, not very crowded. Quiet and the right temperature.

No eye patches , socks given out for overnight flight! The snack on the short haul was a cube of chocolate! The seat was uncomfortable for a long haul - not enough cushioning!

+ Clean, modern plane. - Despite the cabin had only 50% occupancy I was cramped in a row with 2 other people. Almost all other rows had only 1 person. I would have expected the airline to offer assistance other than a flight attendant to tell people in the back of the plane to find available seats. Next time I will not purchase an upgraded seat and hope I get my personal row for free.
