There will be no internet or phone reception from the moment you start boarding. Send your goodbye messages before boarding. Wish they offered at least free wifi for messaging apps like WhatsApp. This seems to be common in Europe and great to include.

early check in at the counter is available just that the downside would be arriving at an odd timing if stopping in singapore.

Never book through Kayak. They can offload booking to third parties that are completely horrible.

Crew is excellent Wifi needs to be improved in order to connect to the internet.

I felt that the whole experience went very smoothly. The aircraft was extremely clean and tidy on boarding. The cabin crew were beautifully turned out very, very efficient and were a credit to Singapore Airlines who are now my favourite carrier.

Excellent crew service. Professional, courteous. Service with a smile. Good food Very decent flight experience

Food was served to different people at different times and it wasn't clear why. The crew apologized for the wait. But it felt odd and inconsistent. They could use charging ports on each of the seats. Mine didn't have any. Also, they could've offered more snacks. It was a 12+ hour flight and no snacks were ever offered. Everything else was OK.

Excellent service. I pre-ordered gluten intolerant meal and they handle it with care. They served me my meal before other people's to avoid crossed contamination. Thank you 🙏

I wish there was a little more leg room between the seats. The recline was good and seats overall were comfortable. I also didn’t like the 2-4-2 configuration.

toilets could be cleaned more frequently, everything else was pretty good.

The crew was very courteous and professional. the flight is relatively clean and comfortable.

a completely full flight - felt quite carmped in, despite being on the window seat. Meal served could better. Surely different from pre-covid trips I used to take to and from Bangkok.

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

Seat did not recline at all, wi-FI did not work at all. Those are both very unfortunate for a 14 hour flight. Crew and food was of course very nice as always.

Chaos at the gate while boarding - no clear signs or announcements

This777-300 is configured 2/3/2 for Biz class straight out of the 80s!!! Not to mention seats are narrow, bed does NOT FULLY RECLINE FLAT as advertised, and purser didn’t know that!! ARM REST HAS A REMOTE TABLET ON IT FURTHER CONFINING THE ALREADY NARROW SPACE!!! WHO thought this was a good design?? After flying the new A350-900 biz class Montreal to Dubai , this was a total let down!!

Food was great. More vegetarian options on menu would be great!

Child’s meal was great along with other nice touches for kids.

Emirates did great! I liked the service, the food, cleanness, and the flight was on time. Much better airline than Qatar Airways I flew with last year.

I would have liked less packaged snacky stuff, more fruit. The crew was great.

Great flight - Clubhouse met our needs, and the staff provided good service. Boarding felt a little chaotic, but given the size of the aircraft, it's always going to be challenging. Whilst the crew were friendly, the number of passengers meant that we received our breakfast items, but had finished breakfast before we were served a drink. Lunch was much better organised, and throughout the flight, the crew were attentive. Found the seats and ICE to be excellent. Disembarkation was fine, and everything possible to expedite the process was being done.

It was delayed for 2 hrs. Flight attendants were not attentive.

Loved the food and beverages available, spacious economy class, excellent entertainment

Very good overall. Highly recommend for all flying to Australia

Helpful staff when I felt unwell. Qantas need to have an audio/music channel so you can listen to various music/.artists

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.

Good check in and helpful staff. Delayed for 1 hour. Took about 45 Mins to get baggage’s at DFW . Food was average ( Hindu meal ) . Overall it was good experience

My experience was great overall. Tanya was particularly friendly and helpful the entire trip. I was very pleased with her customer service skills. The plane was an older aircraft but the entire way was comfortable with barely any turbulence at all. Qantas should speed up its fleet renovation. Totally recommend using this airline.

When I originally booked this flight, I was expecting to travel on Qantas. When the itinerary changed and the long-haul segment was operated by American Airlines, we were disappointed but remained open-minded. Unfortunately, the overall service experience fell far short of expectations. This was a long-haul international flight. Getting up periodically to use the restroom or stretch is inevitable, especially on flights of this duration. However, each time we stood up, we felt as though we were inconveniencing the crew. The tone and body language often suggested that we were in the way or disrupting something simply by moving about the cabin. As a result, I avoided getting up as often as I needed to and was physically very sore upon arrival. Meal service was similarly impersonal. The options were presented in single words “beef or veggie,” “pasta or beef” without any description of what was actually being served. There was little engagement or courtesy beyond that. Even simple expressions of gratitude were often not acknowledged. I am accustomed to no-frills travel and do not expect luxury. What was disappointing was not the absence of extras, but the absence of basic warmth and professionalism. On a long-haul international flight, small moments of courtesy and humanity make a significant difference. In this case, the experience felt transactional and dismissive rather than welcoming. I hope this feedback is taken constructively, as there is a meaningful difference between efficient service and indifferent service.

Qantas is always subpar beyond comfy chairs for a domestic flight

an hour late, then had to disembark on back stairs and take 4 flights up to get to main airport. No warning, and difficulty for those with canes and poor knees.

Business seats not as comfortable or private as most competitors (e.g. Qantas was outstanding), and movie selection was much more limited than Qantas or United has been recently

Boarding was not as per sequence Light snacks were not available Window had hair oil stains and water condensation

3 hours delay ,we changed plane after boarding and waiting inside

Apart from the staff at the airport who were amazing the rest of the experience with scoot was disgusting a very basic flight packed and uncomfortable no consideration to a disabled traveller. And even worse from Singapore to Vienna. All about the money. Not even a complementary coffee or juice. From the airline. The staff at the airport didn't look at me as been disabled and no help not even a wheelchair was offered. The food on the plane was cheap and tasteless and expensive no entertainment on plane and WiFi which had to be paid for was intermittent at best.

Uncoordinated boarding, seat comfort is terrible, even toilet is so small that overweight people wouldn't fit in. Baggage scam with additional fees. Stay away from this airline.

Forthright communication to the customers regarding services offered and any fees involved.

Scoot is a no frills budget airline. Do not expect a legacy airline experience.

I have taken more than 50 flights in the past year and this is the worst onboard experience that I've come across. There's always a risk with budget airlines and their creative views of customer service. Having bought a standard seat, we boarded at the assigned seat - we naturally couldn't choose ourselves as that would be extra cost. After take-off, the person in the row in front leans back their seat. As a frequent flyer, I believe this is their right, so I try to lean my seat back as well to have the same space available. However, my standard seat could not lean back, as the row behind was an exit row. As I had paid for a standard seat, not a less space than standard, I moved to the completely free row behind me. This was not allowed, as due to extra legroom, this would cost extra. Subsequently spent the next 30 mins discussing this scenario with the crew. I have no issues with budget airlines and additional charges, but if I pay for a standard seat, I want a standard seat, not one with less space. As you do not offer me a discount for the less space, do not try and charge me a premium, when I find a free seat with more space. It works both ways Scoot.

Finishes were quite worn, including our very scratched up seatback. No entertainment available, and the WiFi (even for “ScootHub”) was very slow. Crew were somewhat friendly.

Food & lower the prices. Look at Air Asia food look better & affordable

Not a frequent user of their website booking. Booked my check-in baggage and only realized that I did not book my check in baggage for return flight. The receipt was not clear in identifying that as well. Was charged exorbitantly at check in counter. Bad taste for sure when it is a business trip and not leisure trip. Baggage was delayed for more than an hour at belt back in SG.

Horrible. The people that get this flights are very sick, dangerous and unhygienic

Jane at Sydney International airport check in was amazing. She set up the whole experience to be a positive one.

The smells on this plane were disgusting. So many sweaty and unhygienic people i couldn't stand it. I dream of being anywhere else in the world when I am on a JetStar flight they suck.

One of the better flights I’ve had w Jetstar. Smooth boarding, early take off, on time landing, very courteous crew, clean plane.

local frequent travellers know that Jetstar’s flights between MEL and LST are turnaround flights so those in the morning tend to run on time and become delayed increasingly through the day. We observed how the staff at check in and boarding try to assist, guide and facilitate travellers - they were courteous, efficient, amiable while enforcing Jetstar’s baggage requirements. They try to speed up boarding by having passengers board from both front and back. We would take Jetstar again.

The issue was a 4 hour delay to takeoff with very sketchy information provided about the available of the flights delay. Passengers were not informed of gate changes and how long the delay might be. It ended with a late night 2 hour drive to our home which was not ideal for elderly people.

Flight was fine with boarding starting a few minutes early. Not a fan of the crew pushing political messaging regarding indigenous naming of Brisbane city… really pushed it like I haven’t heard on Jetstar before.

Improved experience over our last years flight when also we flew local but on an international scheduled flight. The double processing is still unwelcome i.e. by security and then by border force having to produce a licence and boarding pass repeatedly on departure and return. Obviously suits the airline rather than the local traveller. The flight and crew were good though a helper on return was offhand having to push the wheel chair did the bare minimum we felt.

Flight on time. New plane. No entertainment screen just device. No offer of water. Didn’t order food.

Flight was delayed both directions but once in the air was ok. Boarding out of Melbourne is just a mess.
