Although the flight was delayed and out of their control, we boarded and were underway in no time. The crew were great, the service A1 and the meal was superb ( I had the chicken dish). I would fly with Qantas again, anytime. Noel Swift

Although the flight was delayed and out of their control, we boarded and were underway in no time. The crew were great, the service A1 and the meal was superb ( I had the chicken dish). I would fly with Qantas again, anytime. Noel Swift

My flight with Qantas was excellent, the crew were exceptional, the food was very good, and the seats were surprisingly spacious and comfortable. I was extremely disappointed when my checked bag did not make it onto my connecting flight, but was pleased with the ease of filing a report of a missing bag with Qantas at the Auckland airport - there, my pleasure ended. I can see, with an apple tag on my bag, that it is still in Sydney and has not moved in more than 30 hours. I shared the tracking information with Qantas and was assured when I filed the missing bag report that my bag would be delivered first thing the next morning on the next flight from Sydney to Auckland. Qantas' missing bag tracking feature still lists its status as "searching for your bag, check back later" more than a full 24 hours after filing the report despite my having shared tracking information, a photo of the bag, and calling the customer care line and being assured that an "urgent action message" had been sent to the team in Sydney. The lack of communication from Qantas' customer service department and the lack of action after an incredibly expensive business class ticket price is outrageous and has, definitively, affected my willingness to consider flying Qantas in the future, much less on long-haul international flights with high cost airfare.

Going from Sydney to London on a single flight number was very convenient, not having to worry about changing planes. Entertainment system on A380 economy cabin is very dated. Lavatories are small. The self serve refreshments have been significantly reduced since the A380 first started.

Great food and good entertainment options for the long flight.

It seems that qantas are trying hard to regain their status as Australia's premier airline. I only flew economy but happy with the service entertainment, food, configuration everything.

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

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.

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

It was a good flight and no complaints. It just wasn't anything that was better than any other flight.

Leaving early was wonderful your seats are for a small person

I had excellent experienced flying with Cebu Pacific on my domestic flight. However, no food and beverage serve might be due to short travel time of 40 minutes.

Your check in lines were terrible everything else was great!

Bags lost for the second time. Will not fly with Cebu Pacific again.

Delays on the tarmac, uncomfortable even after paying extra for premium seats. Bags lost in transit, no compensation provided

Delay and flowing long wait for leaving the aircraft after landing. IDK, if it's worth.

Terrible, I will never ever ever attempt to fly on Cebu Pacific. I understand that it’s a cheap flight option but they take cheap experience to the next level.

The flight was delayed for 3 hours and I missed my transit flight.

Was denied early boarding for a hot seat row 1C. I asked gate attendant why I couldn’t I board as I paid extra for that seat and it’s privileges that come from purchasing it. and she said no that Cebu Pacific does not allow it. When I boarded plane finally I had nowhere to put my bag as the seats behind me had taken my overhead area. The flight attendant said that the gate attendant was wrong. I fly a lot in the philippines and to Japan and now I have no choice but to fly with Air Asia. At least they board with zones and allow rows 1-3 to board early.

I am 74 hrs old and I appreciate walking on the ramp instead of using the stairs. Too bad they didn’t have that on the return.

Delayed 50 mins. Check in was excellent, boarding was good, everything else was OK and perfectly acceptable for a budget airline. Price was excellent. I noticed this airline had two other flights to our destination cancelled so not very reliable.

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

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.

Flight was delayed more than 1.5 hours. Gate changed multiple times

no announcement about why we where delayed which is very poor

It is what it is - nothing more, nothing less. No entertainment onboard but one kinda knows that when buying a ticket on a no frills airline. I choose Jetstar only because of price.

Plane was delayed both on arrival to Sydney and departure. We boarded the plane while it was in the process of being refuelled, which I am certain is against CASA regulations. Comfort for anyone over 6 foot is non existent.

Online checkin was a nightmare. They kept popping me into Chinese language site which I can't understand.

The flight take-off was delayed which was fine but the staff seemed pretty over their jobs. The seats are very uncomfortable and the food was pretty average. Overall is was okay.

Freezing onboard and staff refused to give me hot water “because we were landing soon”. The plane arrived at the gate an hour late. And there’s an air leak in one of the bathrooms. Very scary noise.

Batik Air is racing to the bottom of the list with its consistent flight delays. Especially out of Malaysia. Shocking that they keep getting away with it without any form of punishment from the authorities. Also very inconsistent rules on cabin luggage.

Delayed for 3 hours, need to pay extra for drinking water.

The OD2204 KUL-LGK was delayed 40 minutes due to air-condition malfuntion, after inspection the technician give green light for the flight to go as usual but the air-condition is still not working properly, passengers complaining to the stewardess but they cannot do anything, I did tweet to @malindoair to complaint but no reply from them … hope this Batik Air is not having problem like Rayani Air and I do hope the management do respond to my complaint as well

Nasi lemak was horrible. Plain white rice, tasteless sambal, no cucumber, no kacang, no ikan bilis. And the chicken was colourless and tasteless, tasted like boiled chicken. Entertainment system didn't work at all.

2 delayed flights - hotel layover in a different country- lost baggage.

You get what you pay for. It’s functional and gets you from point A to B in good comfort. However, food options are limited and cash only, Crew is a hit and miss .. they get your attention if you reach out.

Good leg room ... air conditioning was a bit warm don't Book row 8 ... no windows

They got to the terminal late, with no one on the arriving flight, boarded us late, and left us sitting there for 2 hours before they got us off the ground. They knew they were going to be late, yet they never got an updated flight plan from their head office until long after the flight was supposed to leave. They could have cut the delay in half, of at least let us stay in the terminal. Really just horrible planning.

The worst kind of budget airline. To be honest....the plane was not that bad. Would have been good to have some food choices and some water. What was by far the worse is the passengers/customers that this airline attracts. Coughing and spluttering all over one another with no masks. Just disgusting. Pay for a better carrier and get a better class of passenger.

Flying from Koh Samui to Ha Noi with a layover in Bangkok. Vietjet cancelled flight. When I went to the counter they told me to call from r information. I asked for the number and they said they couldn’t give it to me. Be a little taken back I asked him to repeat that while I was recording on my iPhone. He told me that was unacceptable and called the airport police. I deleted the video but had to deal with a big hassle. Then booked with a different airline. Vietjet wouldn’t refund the ticket. Luckily Chase Sapphire didn’t have a problem with refunding me. Vietjet blows!

Terrible customer service. My last choice to fly now if there is no other options.

For budget airline, it’s not bad at all. It’s definitely value for money. I added on the priority check in and eSIM. It’s well worth it.

Waited for 1 hour on tarmac because they couldn’t locate a tow truck. Flight was fine once we eventually took off.

Late departure, late arrival, and personal items on laps during takeoff and landing. Departure gate opened on time, but no direction as to whether to board at front or rear of plane based on seat number. Fashionable staff with sunglasses inside the plane and cockpit remained for ten minutes after the boarding complete announcement. For a scheduled 80 minute flight, adjusted to 65 minute as noted on takeoff; the total time on the plane with delays was r more than two hours. No confidence had there been an emergency that anyone would have been able or aware of what to do.

Our flight was delayed for about 3hours however the ground crew made it sure that we will not miss our connecting flight from Hanoi to incheon.

Paid for seats near the window but given seats right at the back, near the toilets. This location was so noisy with the blasts from the aircraft engines blowing beside. Not a nice one 😞.

Some chair in the flight should be maintained, but I think they may not have time to check every seats, since it is high demand in this period.

Our experience was the worst. Over 2 days flight was changed and delayed 4 times. Not impressed

Flight was okay. Seats were a bit cramped and not that comfortable, especially for a 7-hour flight, but you get what you pay for. Food has to be bought also so plan ahead. But if you can tolerate it then it’s not a bad deal! Staff are nice too.
