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

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.

Mostly good and consistent of Emirates service. Christmas menu was great initiative and tasted good. Taking the bus from terminal to the plane spoilt the experience a little.

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.

Love that you can walk directly to your gate from the Emirates Business class lounge, very convenient

The journey was nice, all the crews were very good and services are excellent

Could not board flight due to visa issue and emirates staff at the airport refused to help rebook flight because it was made by another provider. It took hours of communicating with my provider and Emirates staff each of whom said it was the others responsibility. As the time passed, I was eventually told it was too late for rebooking as I needed to do this at least three hours before the flight. Emirates staff also said the would unboard me but I believe I was recorded as a no show. Our first flight from Sydney to Dubai was more cramped than other airlines which was surprising considering their reputation.

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

The food options were excellent for Economy. It was difficult to find the lounge after clearing security and boarding was clunky

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

My journey with Qatar Airways from Ahmedabad to Jacksonville on 3rd February 2026 was truly exceptional. The entire experience reflected comfort, care, and world-class service. Complimentary high-quality Wi-Fi throughout the journey was a welcome luxury, especially on a long-haul flight. The vegetarian meals were thoughtfully prepared, delicious, and served with attention to detail, along with a fine selection of snacks and beverages. What truly elevated the experience was the cabin crew — graceful, courteous, and genuinely attentive, delivering outstanding hospitality at every step. This journey perfectly showcased the premium standard Qatar Airways is known for, and it left a lasting impression. I would gladly fly with them again.

First off, it wasn't clear that my first flight was to be operated by IndiGO. While the flight itself was fine, this meant that my whole initial check in where I would've properly verified my seating on my Qatar flight/requested an upgrade was impeded by the fact that I had to check in with IndiGO. They said I would separately have to go to Qatar counter to deal with second flight leg issues, which was impossible given how long the check in took/no time available to do so.

Impressive as always. It is the airline of my choice, The dessert on the 2nd flight DOH-IAH was somewhat dry (the cake with cream etc) Check-in and boarding experience was fantastic, with the exception of CCU airport where chk-in staff refused to help with aisle seats stating the flight was full and accommodations were beyond him. Once I boarded there were plenty of available aisles. I was disappointed that this could not be done by self during online chk-in nor at the airport. Nothing more to add. Overall a good experience, TY QTR

This flight was a very good trip for us. The crew were very friendly and helpful. They made arrangements for my husband to have assistance in boarding. We were not expecting a meal, so it was a pleasant surprise on this short flight to have a meal and beverage from a very courteous crew.

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Seated in row 6 you are separated from business class close to the toilets. The is a high panel in front that obscures forward viewing, coupled with no window view. Service is limited as the area is not in view of the attendants. It is closer in proximity to economy than business class.

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

The flight overall was good. The attendants did a good job except that 1 female had too much fragrance on. The other things that made the flight unpleasant were out of the airlines control.

The seats seemed smaller than other business class offerings. The entertainment menu was limited. Flight crew was good.

Food quality and varites were very minimum. Surprised to have no desserts. Business class tickets should have lounge access and seats selection. They should be allowed to board while people with wheel chair, secial assistance and family with childrem.

Dear Team, I purchased a full travel package that included 2 checked bags through you and JustFly. However, when I arrived at the airport, my ticket showed 0 checked bags. Since I was traveling internationally to India with 2 bags, It was a $200 per bag at the counter, which was extremely disappointing. For an international trip, why would I ever choose a no‑bag option for only $20–$30 less? This seems like an error in the booking process, and I am requesting clarification and a resolution. I have called JustFly and on phone for 1 hr :53 min and they couldn't help till I show some kind of proof etc which isn't possible but besides that love your service and using it for years !

Good one but just notice that you have to ask several time to get water or coffee .

Ethiad wanted to charge me $1100 for 2 checked bags on a ticket that was $550. Nother the airline or airfare assist was willing to help before arriving at the airport. All parties said it was the other responsibility to help. Never flying ethiad or using kayak again.

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

It was mediocre. Honestly, the flight was late but that didn’t bother me as I had plenty of time. The only thing that bothered me is that the crew never asked to make the beds for us in business class. Maybe the crew was exhausted and that just didn’t occur to them.

From the start of my vacation at Logan Airport, Boston it was chaotic. I'm praying my flight home is better .I'm grateful that we landed safe

Nice crew , clean cabin , food was delayed due to problem with the quantity .

Kayak and Aran grant issuing business class tickets without lounge access and sometimes 1 or 2 connections in economy class. It’s very disappointing to find out that after buying the ticket. Never buy tickets on kayak and Aran grant again

It was peaceful excited We enjoyed it always Turkish peaceful excited

IAH to Istanbul was outstanding across the board. The flight from Istanbul to Male was good, not great.

Cancelled with no notification and no assistance from ground staff re options or rebooking, where to stay or how we could get home to LHR.

Our flight was canceled with no rebooking offered. We are still waiting for a refund and had to book a very expensive flight to return to Toronto without any compensation or help from Turkish or flight hub. Extremely poor service during a time of crisis, speaks volumes about the type of airline and flight hub as a disaster of a company with zero accountability

Our flight was delayed for one hour is their a credit?

Bad sitting every flight not good experience with food either

I'm very tall so the leg room of the seats could have been a little more spacious. Otherwise, everything was excellent

Everything was good except that they didn’t give us seat for our connecting flight in Istanbul from Cairo. This created a panic situation. Hopefully they give all customers connecting flights seats right from the start.

Requested food options were always finished. Supplied food items were good but of course not the desired choices.

The airport staff never announced that boarding has started. Both at iad or Islamabad or Istanbul.

Even after a delay, getting off the ground, thanks for keeping me safe, the airline made certain that my connecting flight was rebooked to get me to my final destination. It was actually rebooked twice, and my luggage still managed to meet me. The airline gave me a credit for food and beverage to be used at the airport vendors, regretfully, the credit did not transfer to my final boarding pass. Oh, well…

Flight was great. Smooth flying, movies good. Open seats allowed for good stretching.

Food was much better than my outbound flight. On-time. Good service. I had a problem with my entertainment screen, but the attendant fixed it promptly.

Everything went smoothly and the staff was very kind. I’m glad I purchased the extra leg room for my long flight; it was totally worth it. We were served 2 meals for a 9 hour flight which I was not expecting and they were very tasty. I appreciated them being vegetarian. Customs line in Munich was long; I had a choice to have a 1 hr 40 min layover or 2 hr 40 min layover; I took the longer layover which I was thankful for because my flight was delayed 30 minutes and there’s a good chance I would have missed my connecting flight. This was my very first international flight and I would fly Discover again without hesitation. Thank you for taking good care of me!

Crew was very courteous, friendly and professional. Caring and attentive.

Poor food on flight between Toronto and Stockholm Airport Toronto too crowded

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

I like the service and the efficiency. I am lactose intolerant and the lactose intolerant meal in business class was not astounding. Also, the business class fully reclining seats are not that comfortable.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

They are professional. Nice crew. Still flying Boeing 747. Thank you for that. I love this airplane. Traditional.
