As always Emirates is always dependent on the crew you get on the day and today was a good one. Everyone knew what they were doing and gracefully without hesitation . Great conversation all round even about the food and wine.

As always Emirates is always dependent on the crew you get on the day and today was a good one. Everyone knew what they were doing and gracefully without hesitation . Great conversation all round even about the food and wine.

Very bad service and food variety will never come back again

Offboarding in Dubai was a bit confusing. The bus dropped us off, we passed the security, and then we were again in departure, no clue, no guidance on where to get our luggage

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.

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.

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

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

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.

I paid extra for seating when first booking flight to be in a comfortable economy seat They still changed it to a middle seat regardless. When I asked for it to be changed back to aisle, they could only give me one at the back of the plane in the least comfortable seats.

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

The boarding process was awful-the computers were down and there was no way to check in. Took extremely long, very chaotic and no guarantee our bags were even getting on the plane. I was also delayed and took away from any time i had to catch a connecting flight.

I always fly with Qatar air and you are the best. Keep up the good wor, after travelling with Qatar Air More than 80 times, you never offer to upgrade me.but it happened to my friend companion some time. Any how i still enjoying travelling with Qatar air and wait one day to upgrade me too. Best Regards

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.

Turkish Airlines made a long flight from YVR to IST a great flying experience. From the attendants, to the food, to the entertainment program to all the extras, a twelve hour flight ‘flew by’. Late departure and arrival was not the airline’s fault.

Flight got cancelled for good (apparently due to jet fuel concerns), and we had to re-book to Hannover, Germany instead.

Both of our Business Class seats were broken. I'm sure they didn't just break before we boarded but were broken prior. They would not recline. We could sit up straight or lie down, nothing that would allow us to sit back and relax on a 12 hour flight. Totally unacceptable. Very expensive and a waste or money.

The seats seems abit small and the reclining is too much, the seat in front of me came back too much and made it uncomfortable for me.

A lot of snacks and provided on request by traveller. Preferred meals which were on their menu were not always sufficient for those who wanted them. We were told 2 different items and offer which we asked for were not offered initially. We rejected the 3rd item given as a substitute for our initial choices which we didn't want and so we didn't accept it. Eventually our initial choice was offered. During service of coffee and tea, the crew member didn't offer us and moved back. Luckily neither of us wanted tea at that time. Crew members must avoid behavior that may be suggestive of discrimination

Flight was delayed. While standing at the gate, a note appeared on the sign saying the gate had changed to a gate far away. No member of the Turkish airlines team got on the microphone to instruct passengers to go to the other gate, to ignore the chiron, etc. Finally, the message disappeared. Eventually, the flight began to board. Very slowly. More slowly than I experience with other airlines. Though Istanbul may just be slow . . . In all other ways, great flight, great entertainment (top notch movies), great service, excellent food, comfortable lie-flat seat, dimmed lights, etc.

Staff at the airport wasn't helpful or friendly. Probably the worst airport experience I have ever had, going and coming. The staff on the plane was better. Still not super friendly or personable. However, they were not rude like airport staff. They ran out of certain menu items. Maybe could have been prepared better? Overall just ok.

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 delayed for one hour is their a credit?

Typically good service onboard but baggage delay in airport was significant

I payed for extra leg room but in last moment my seating place was changed and i got standard one seat. Staff was not able to do anything , so was very disappointed because of this.

They lost the baggage and said it was deleted from the system. I had baggage tag so was able to file the complaint but there was no PIR number and update so far

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

Unfortunately the flight was cancelled so I never got to go

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 !

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.

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 .

It could not have been cancelled and the rebooking pro could have been smooth, not requiring me to be on hold and standing at check-in counter at Air Canada (not AC fault) for a total of 3 hours. Ridiculous.

1. One of the crew who was managing the crowd in the business class line specifically asked me if I am travelling by business class while I was standing in the business class designated line. She specifically was asking only me and no one else. Seemed to imply that I may not be aware of it and may be I don't belong there?(Based on my color?) 2. The business class seats in the aircraft was average regular economy seats with middle seat kept free.

I had a good comfortable seat. There was nearly an hour delay. There was an accident with the champagne, but I was well compensated. These things happen sometimes.

I ordered Hindu meal and expecting a vegetarian food. Instead I got Chicken. Also entertainment system was so bad and slow I was never able to use it

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

I had a sprained ankle and had to go down the stairs to the bus and then up the stairs to the plane. Food / dinner served cold

We would have missed our connection from Munich to Boston but we had a van outside the plan that wisked us to our terminal. Much appreciated and we didn’t even realize that Lufthansa had done this until the announcement on disembarkation. Well organized airline! Will definitely fly Lufthansa again!!!

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.
