I had selected seats together for my family of three when I first booked my tickets in February. However, I realized only when I checked in at the airport that the seats I had selected were no longer assigned to us and we were completely scattered across three different middle seats instead of being seated together! After requesting the Singapore staff to have us seated together on a full flight, they managed to find something but it was right next to the rest rooms and the whole journey of 15+ hours was really unpleasant. They said that the seat selection isn't locked and the airline can reallocate the seats anytime. No one ever told us this and it was a terribly unpleasant surprise. Will avoid Kayak/underpricer and Singapore in future

Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

The booking experience was bad. Our six character booking ID number disappeared the day before the flight, We could not find out what happened or what was the status of our flight, scheduled for the next day. We finally found the right number to contact Singapore Airlines on the matter (not easy). The Singapore agent worked through the issue in a little over thirty minutes on the phone, the day before the flight. That was great. I'm very happy with Singapore Airlines and their performance. Contact with a competent person on the matter was near impossible. It seems no one in business these days wants to deal with customers once they've pocketed the money. There were resellers, including Kayak, involved in the chain. When we finally got through to Underpricer, we did get a return call that could have proved helpful. But by that time the matter had been resolved by the Singapore agent. Majestic Vacations, the reseller who received the payment was less than worthless. That's just a fast buck operation. Ugh.

Fantastic patience when one of the passengers behind me was an absolute horrible, horrible person and the girls just kept smiling and doing their job with patience and kindness. Well, done to the crew.

Excellent meal served with real utensils, cardboard served hot meals instead of plastic utensils and plastic covers. Quick service, friendly and accommodating stewards.

When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

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.

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!

On the way there the food was not a good Standerd and fly Dubai is very cramped and again the food was not a good Standerd but on the way back food was excellent and staff were very helpful specially a lady which I took time to take her name Maria and another staff which was South African very very polite and helpful i am very sorry that I got her name

Very bad service and food variety will never come back again

Everything was perfect. Staff were informative and professional and flight boarding, flying and de-embarking was smooth. I would certainly travel with Emirates again.

My baby was with me it was really good experience with emirates

Fantastic as ever. Great staff super catering and excellent service.

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

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

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

Everything was superb, only bad point was that the fast track on London Heathrow arrivals was not handed out to me and I had to go back to the gate to collect it.

Small twin prop plane. Basic flight. Food was half a chicken & pesto sandwich. As the flight departed after 12pm alcohol was available. No on board entertainment. No wifi services.

From start to finish, every part of the experience was outstanding. The care and kindness shown to my 95-year-old mother was exceptional—truly 10 out of 10. From the assistance she received at Sydney Airport while boarding the plane to the help she was given when arriving at Wagga Wagga Airport, every staff member was friendly, professional, and genuinely caring. They made her feel comfortable, safe, and well looked after throughout her journey. A heartfelt thank you to everyone who helped make my mother's trip such a wonderful experience. Your compassion and dedication are greatly appreciated.

It was ok, but not what it was like 20 years ago

I'd like to see AA's flight safety record clearly and prominently posted online.

Wheelchair assistance to move through the terminals and to/from the plane door was excellent. No vegan snack on the flight, only something with salami and cheese in it.

The flight was good, long obviously but smooth. The seats are pretty small, definitely notice a difference for long haul compared to Emirates or Cathay Pacific it’s more like medium haul seating for space. Food options were good, children’s meals were good for my fussy 3yo.

After British Airways cancelled my London to Sydney and Virgin Australia refused to refund, there was no ways I would try Virgin Australia again, so it was Qantas - what a good flight experience. So much easier to get off an international flight and get a local flight without having to add extra amounts for baggage

Amazing! Was put on the earlier flight and I requested for an aisle seat and was given it. Thanks Qantas!

Enjoyed the new possibilities of in flight entertainment. Been awhile since I've flown, and that was a nice surprise. Being able to pick from such a variety was personalized and welcomed.

Old plane nothing worked no charging facilities for phones etc

Economy travel is really hard with no room to move especially when the person sitting beside you is an XL or XXL size person who if moving could hit your face

Being a QR Platinum member traveling in business class, I expected the staff to be more courteous. Unfortunately, the lady staff was rude attending business class 1K side.

Good staff, good intent, decent entertainment. More seat space would always be of benefit

After going through security and waiting for the flight at the gate, there was no access to bathrooms and no place to charge a phone while waiting for the flight. But once I was on the plane, everything was very good.

Terrible. The website insisted that I wasn't logging in correctly to confirm my flight. It also wouldn't let me register as a member. I was unable to get a boarding pass until 4 hours before the flight so I couldn't get through security and had to wait. It was unlike anything I've experienced in decades.

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

Qatar Airlines code share with Indigo has been a terrible experience for me on these notes: 1. Indigo changed by flight without informing me of the change, they did not ask me if I am okay with the change. I discovered this change when I was trying to do online check-in through the Qatar mobile app. When I called Qatar customer support, they mentioned Indigo changed my flight due to the original flight being cancelled, but the fact is that flight was scheduled and departed correctly, it was never cancelled. 2. When asked why my flight was changed without informing me, they mentioned that they sent email/phone call to my travel agent, and it is was my travel agent that did not inform me, which again was another false statement. 3. I called Qatar Airlines (third call on the day of my trip) to request them to put me back on the same flight, they mentioned that they could for an extra $2500, as the original class I was booked on was not available, we are still talking economy only not business class, I said no way. 4. I called the travel agent, and they mentioned that they will work with Indigo and asked me to be prepared to travel on the later flight I was bumped to. While I was making my hotel/taxi arrangements for the new flight, I got a call and email saying they were able to get me on the original flight with no extra cost. So, after 2+ hours of talking to customer support, and a lot of stress on my last day of vacation, I flew back as originally scheduled, but this nightmare is just a horrible experience that I will never fly on Indigo/Qatar again. Thanks and regards, Vijay

Qatar is the worst airline experience I had in a long time traveling business class, I believe the hype is all paid for by bloggers.

I liked the food and services provided. I think the seating should be updated cause it’s to congested for economic class.

The screen was not clean.It had stains of previous customer .Also the toilets..My daughter got urine infection. Not happy with the cleanliness of aircraft.Also requested multiple time hot beverages but not served at all sighting disturbances. Request on behalf of every passenger please sanitize and clean as we stay for 15 plus hours..

I ordered a drink, but never got it. I ask what type of drinks they had and they could not tell me and there was not printed copy that I could find that is usually on most airplanes. They served dinner and never walk back to see if any need a drink or anything afterwards until they served the snack just before landing.

Check-in wait time was quite long (understaffed for the volume of customers), but energy and hospitality of flight crew was great!

I really enjoyed the flight…and food and the hospitality but didn’t get the food I requested for.

Everything was terrific. Kevin, and the whole crew, were exceptional. Five stars all around! Thanks so much.

Flight held at gate for other passengers. We ended up being late and missed connection

Should have more cosmopolitan food choices - too many Indian dishes - the only entree not Indian was lamb which I don't eat

The plane was ancient, and its technology was in disrepair. None of the charging stations worked, and the screens were barely functioning.

Worst thing: Luggage took forever to get at LAX despite priority bags. Best: Flight attendants were great!

It was my experience w Kayak that was negative. I’m never using kayak again

The Business Class seating arrangement hasn't been upgraded yet. When getting up to go to the bathroom, you have to climb over someone's stretched out legs.
