Always enjoyed flying with Emirates, flown with others but they don't really measure up. The others are cheaper without a doubt, but not as good as Emirates

8.0 ExcellentDave, Feb 2026
Read more Emirates reviews

Always enjoyed flying with Emirates, flown with others but they don't really measure up. The others are cheaper without a doubt, but not as good as Emirates

The crew were absolutely fantastic. They actively asked if passengers wanted refills and if they were comfortable. I was extremely impressed.

Emirates A380s are always wonderful to fly on. Their crews, food and service are always excellent. They are typically on time and the only thing I would change (maybe newer or upgraded aircraft have this) is bluetooth so I can pair my noise cancelling headphones without a cable.

Bathrooms were amazing and first class seat was very comfortable. Food was edible but not up to the standards of other first class meals on other airlines. But Caviar was amazing! So much caviar. Dom Perignon 2015 was room temperature. It would have been amazing if it was chilled down a bit more. Slippers were amazing and amenity kit requested was beautiful. Requested Pajamas never came so can’t tell you how nice they were. Loved the design of the seat and personal storage. Suite was much smaller than other airline’s first class and tv screen was tiny and remote difficult to use. I probably wouldn’t pay for this flight again.

Wonderful Premium Economy experience. Felt as good as Business Class for food and entertainment. Comfortable sleeping too

No kids provided. Instead we were told to have contacted the airline that we have kids and require kids meals. We were not the only ones who inquired about kids meals. It’s odd. Emirates and other airlines give kids meals as standard and before the adult food comes out. The rice in our meals was gluggy and under cooked. The chicken was also raw. Sadly not the best experience with Finn Air. The hostesses tried to compensate with the snacks and drinks but missed the mark by a long way. Especially when paying Emirates/Qantas prices

Can’t complain Only downside was the Kiosk passport check and customs clearance at Melbourne. When will they improve that service🤔

Very pleasant.The crews are very helpful.Food are very good.

Always my favourite airline. On time, lovely staff, clean comfortable seats. Well done

Premium economy on Emirate A380 is simply the best non-business class product. In fact its probably better than many business class if the seat isnt lying flat. The food and service is close to perfect!

Excellent service in business class. Well worth the slightly higher fare as it includes lounge access, additional luggage weight and a full hot meal on board.

HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

We still get drinks and a snack. Love the gift bags too.

business class is old but still done very well by the team.

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

Thai Royal First is very good. Easy check in , Private room in the first class lounge and escort from ticketing to the plane. Once on board crew was very polite, food was outstanding, and the ride was smooth as silk. Restrooms were especially clean. Great Experience

Need to improve on punctuality. My flight was delayed by 1 hour.

Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.

Although booked meal of fruit only The crew had not received this special meal The same happened on my flight Bangkok / CAN The films are so old that best is to use own computer to watch downloads . Serve nuts but they do not warm up . Service is attentive , WC clean

They used Thai Smile plane, which is a smaller model and used to service only domestic flights; hence, the plane is small and quite compact. No entertainment on the flight. While boarding was delayed, it was done in a quick manner.

Despite having numerous passengers held up by American Airlines delays. Qantas (an AA partner) closed boarding with 0 flexibility

Boarding , crew and meals were all amazing. Couldn't wish for a better LOOONG flight from Dallas to Sydney .

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.

Was disappointed that we couldn't use our lounge passes as the booking was a group booking.

I think it is much better than the flight I flew from Sydney to Tokyo.

Boarding was effortless, the food was outstanding, the seats in Premium Economy were extremely comfortable, and the staff and crew were excellent.

I never flew with alliance. Kayak is a joke and none of the flights or times were correct. Won’t ever use kayak again

I missed my flight due to unforeseen circumstances It was, however , an excellent price !

We had a medical emergency, needing to get to an emergency room upon landing at LAX. I let the back flight attendants know the situation. One, David, contacted the pilot, who made arrangements for EMT's to be there when we got off the plane. They went above and beyond for us. We didn't have to go through customs, as a customs person came to us and checked us right at the exit of the jet way. Another wonderful woman, a United employee at LAX, perhaps a customer service liaison, took care of our luggage situation, as we weren't going to make our connection to Bozeman. When we came back to LAX to see when we could get a flight to Bozeman, the personnel are very accommodating and booked us on the next flight out, and assigned good seats. It was a horrible flight, physically, from Sydney to LAX, , but the professionalism of all involved was excellent! We are very grateful fir the way they all stepped in and helped during a very unpleasant medical situation. Thank you!!

Qantas onboard service/meals has degenerated to Budget airline standard transferred to Emirates in Sydney which only highlighted Qantas decline

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.

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.

The cosmetic condition was pretty run down. The carpets were badly worn out. Even the paint on the wings was chipped and peeled! Looks like they are running these 787s to the ground..

The crew was not customer oriented at all, even confrontational . The aircraft needs more attention to detail as far as comfort, and the 1 hour sitting at the gate with no air is inexcusable

no charging point. food offering is limited and very much on the budget line. Overall is not satisfying for such a price and duration of flight.

We were delayed, but there was never any update given. Everyone was standing at the gate as boarding was supposed to commence at 13:10 for a 13:55 flight. We didn't actually start getting on the shuttles to the plane, until after 14:00. No updates, no information given at all.

It would have been nice if I could have actually travelled to Perth. I injured my back and was unable to fly. Scoot refused to change my ticket saying it was not flexible. However I purchased the ticket through MyTrip and it was flexible. MyTrip wanted to charge me an extra $271 to change to a ticket that was only listed as $217. Never again will I fly Scoot or book through MyTrip

Connection flights are smooth, both flight takeoff arrive on time, that will be the best u can expect. Food no order, service no complain, entertainment not seen, cleanliness can be improve.

U could offer everyone a drink ,juice or water.. coffe or tea ...ur air craft isn't a flea market ,where someone has to buy a tea or water!!

Extra luggage after you purchase 1 is gonna jacked u up to 800sgd which is so up to the hook... you could buy 3 round trips ticket on that price.. im so disappointed.. im not gonna choose this airline anymore.. horrible experience...

A good standard flight, a little delayed, on the return flight, comfortable during cruise hour. The food was tasty, the tea pleasant, standing in the rain, on Launceston tarmac, was stupidity. Just delay the exit from the airplane, don’t have us standing around, while another plane slows its propellers. That’s common sense, but overall comfortable, clean toilet, good legroom, I paid for that, last on, first off, get a front row seat.

Cabin crew were really good. Flying in to Perth from Adelaide on domestic flight. The arrival for wheel chair use however has no air bridge provided. Unloading meant a scissor lift. Otherwise a good service.

Knees in back from passenger behind, limited seat pockets, no entertainment.

The Ryanair of Australia. Not impressed. Forced me to gate check my bag as it was over their weight limit. Charged me $125 for the privilege. Then said plane hold was locked and it would have to go out in the next flight, which was the following day. Explained that I was on a cruise the next day and the plane would not arrive until after the ship left, and that it would be impossible to catch up with the cruise at any point. Lady at the gate unimpressed. So to sum up they were ready to charge me $125 to lose a bag. Finally got it resolved by appealing to management, but the whole episode was not good for the blood pressure. The gate lady said they followed the Ryanair business model which means first time passengers get penalized for doing things that other airlines routinely allow.

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.

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

Great. Seats are a little cramped with only a very small recline. Service was great. Food was fine.

The flights got us to our destination. The seats on the planes were uncomfortable.

Over four hours late. No entertainment without paying and same for food. Asked to check in at original time even though we were told it was going to be very late leaving. Way too long time to hang around the airport. Arriving to Sydney luggage did not arrive for an hour. Had to get staff to go and find out what was going on. All this made for a very long day and night for a eight hour flight.

Very disappointed with my recent Jetstar experience. Firstly, it was extremely frustrating that we had to pay extra for basic things like in-flight entertainment and meals. Other airlines provide these essentials even with standard tickets, but Jetstar offered no comfort or amenities without additional charges. For a long international journey, this made the experience very uncomfortable. On top of that, there was a delay on our flight from Melbourne to Bangkok due to parts replacement, which was already inconvenient. But the biggest issue was the massive 5 hours and 15 minutes delay on our return flight, which completely disrupted our plans, caused unnecessary stress, and impacted both our time and health. Jetstar provided vouchers, but they were not nearly sufficient to cover proper meals or any meaningful service at Bangkok Airport. After such a long delay, this felt extremely inadequate and did not compensate for the inconvenience we faced. Overall, this has been one of my worst travel experiences. I am extremely disappointed and will not be booking with Jetstar in the future. I strongly request Jetstar to provide additional compensation for the significant delays and the discomfort we had to go through.
