Airline reviews

The crew was very attentive and delivered great service unlike any other airline. It was our first time with Emirates. Our only critique is the food. Pasta pesto is not very common. Tomato sauce would’ve been more of a crowd pleaser. Beef curry sounds bad because curry can be very tough on the stomach. We were in row 26 and the pasta ran out, meaning no one wanted the beef which says something. The beef was just ok… The rest of the food was very good and generous. The plane speaker sound could be better. It was tough to understand announcements even with headphones. Although we did not need them this time due to the purpose of our trip, we were surprised that 2 checked bags were included. That’d be great for the future. It was unpleasant though that our personal items were weighed (we’ve never had another airline do this), especially when we didn’t have checked bags and almost had our carry-ons checked. Overall it was a good experience, but we wish the prices were friendlier for such a short distance (Miami > Colombia).

It was very exlent flight and thanks a lot kayak

Flight was cancelled without notification. Information on flight status was not available on Emirates's website.

I love to travel again and again in Emirates. Keep up the good work.

The stewardess took a picture as a gift , if you asked for it. Every thing was very good, Especially the food, big and tasty. The service was good, they served water several times, very frequent.

I liked the newer aircraft CRJ-550 since it had WIFI and the seats are more spacious.

Sadly I couldn't get the food I requested as it was out. Also, if you don't want to be woken up make sure the crew knows it. My wife was woken on every service.

Three meals on a single flight is disgusting. Even if I reject them all, sleeping is impossible and all that food (especially wasted food) is just antithetical to a pleasant flight experience. People were chucking multiple abandoned trays on the floor in front of my seat.

I wish any of the US airlines operated like Emirates

Better information about the delay due to screening for US

Amazing airline accommodations. The cabins were so great. The food was very good and the flight attendants were so nice. Made a 15 hour flight seem easy.

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.

Same as already mentioned. This was more comforting as I got my aisle seat for my knee.

Very efficient and professional staff. Food was good and so was entertainment selection.

Initial booking was confusing and had to get new CC issued.

I recently travelled with Qatar Airways from Doha to Dulles in the QSuite, and the experience was nothing short of exceptional. The QSuite truly feels like a First-Class experience, with its luxurious design, privacy, and comfort. The cabin crew, especially the lady in charge of the cabin, was remarkable—professional, attentive, and genuinely kind. The food was excellent, and the comfort of the seat was absolutely first-class, making the journey smooth and enjoyable. While the in-flight experience was outstanding, I have a few points of feedback. Firstly, the content available in the in-flight entertainment system could be expanded and upgraded to include a more diverse and updated collection. This would elevate the entertainment experience to match the premium standards of the QSuite. Secondly, regarding the Wi-Fi service: while QSuite passengers receive one hour of complimentary Wi-Fi, any additional usage requires a fee of USD 10. Considering the premium pricing of QSuite, it would be more fitting to include unlimited Wi-Fi as part of the experience, further enhancing the luxury offered to passengers. Lastly, I must highlight an issue with luggage handling. Unfortunately, my luggage did not make it through the transit, which was disappointing. While the ground crew assured me that it would be delivered to my home on the same day as it was arriving on the next flight, this promise was not fulfilled, and the delay added unnecessary inconvenience to an otherwise excellent experience. Overall, the QSuite experience was exceptional, but addressing these areas would further solidify Qatar Airways’ position as a leader in luxury air travel.

riding in first class, you don't expect every time you order your dinner or breakfast that the first thing the stewardess says is Let me see if we have any left. Also, the food selection was not great: 3 of 4 entrees had mushrooms and I dont eat mushrooms, the 4th item was 'let me see if we have any left' and this was within 30 mins of entering the flight! Same experience level, it didn't feel first class this round.

Do not overbook flights and kick out confirmed ticketed passengers :-(

Vistara i bought a biz class fare but a few days before vistara always changes my biz class flight to economy .. happened to me 4 times .. seated could be wider .. boarding could be more organized .. crew did their best but not enough resources all in all very poor experience Qatar Delhi .. only complain .. no clear signage to lounge for transferring pax .. its a Delhi shot coming.. no feeling of exclusivity for biz/ 1st class pax.. but everything else was much better .. once i boarded Qatar .. i loved it Qatar to Washington .. only complain i boarding .. too crowded .. no separate area for biz/1st class should hav completely separate area for upper class.. security is stifling pax comfort by the gate ..but everything else was great

I like is everything is good seets are little uncomfortable during the long flight ✈️ Doha to us , luggage 🧳 came too late overall very nice thank you for all

The sleeper seats, the staff, and the food was truly delicious. I loved the mocktail options.

Great food, and lots of it. They made us come to the gate two hours before the flight and you were stuck in the enclosure until you boarded with no bathroom or food or drink. My seat in business class was very claustrophobic, I could barely get into it and a large board blocked the window and made it even more claustrophobic

Cabin was kept very hot and it was uncomfortable. Entertainment system did not work at my seat. Crew and service is fantastic

The crew on this flight provided exceptional business class service to me.

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

The airline could improve its business class seats and privacy in line with its competitors.

The seats have to be one of the worst when it comes to comfort and you have to scramble around to out your handbag in the overhead. The food is still awful. Definitely will not travel on Turkish again and wouldn’t recommend it to anyone for sure.

Very happy with the service, comfort, and food on Turkish Airlines. Security and check in was great.

Movie selection was ok, but could be better. Would like to see greater selection of newer movies.

Loved the check-in experience. Very friendly staff and not crowded. I did wind up with a middle-middle seat, which was quite uncomfortable. Always appreciate the very professional staff on TAL.
