The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

Klm start boarding while somw air issue in the plan

The service was great. However the lounge only gets passing grade

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

You should not have to pay for WiFi in business class

Despite the booked seats in front of the land we were moved to the back of the plane even first like 8 lines were totally without pasangers. When I tried to sit on empty seat flight attendant asked me to go to my dedicated seat in the fully crowded back of the plane. She was not able to explain why. Food was very poor on flight LAX - VIE.

We had a wonderful experience overall. The only issue was check-in our luggage at the Split Airport counter. It was very confusing because we needed to pay for baggage.

Austrian Airlines help and service was fine, but Kayak misled us into believing we had purchased a Business Class ticket. In fact, the tickets were only upgraded Coach Class tickets with luggage restrictions that belonged to the Coach Class. Very disappointed! Paid over $$$$ 9K for the two tickets. Very disappointing!

Landing was a little hard. Food was not great My prior review was for the flight to nyc too

Landing was a little hard. Food was not great. No options.

Five star experience all around except for my seat, which was broken. It would only go down 70%.Of the way. It defeats the purpose of buying a business class ticket if you don’t actually get to lay flat..

I love this airline.God bless CAO and the whole staff of this company

Great staff, efficient and knowledgeable. Very helpful with others and considerate towards those with children

WiFi would have been nice and some more powerful usb ports, available ports could not keep my phone’s charge much less charge the phone.

Not so good. I paid for a preference economic seat, and I couldn’t incline it back because it was blocked. They explained me that because is the last before emergency exit. The company new that but it was not explained in the seat selection

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

Worse fight I ever take since I start flying , still have even made home , and crew abandon us half way home . No water no food and no even anyone to answer our questions

The staff was the best I have experienced as a frequent traveller in a long time.

The staff was great and probably that's the single most thing that distinguished this particular Qatar flight from my average typical experience. They genuinely wanted to please you and do their best.

Liked some flight attendants. 1 was rude I'll not say her name I don't want to get her jn trouble on my flight back to Dallas from Doha. Very rude to some races of people clearly. She needs a better attitude and bedside manners. Asking her questions and she responds "WHAT" twice rudely like I was bothering her and "is it going to be cranberry or mango juice with an attitude".

All the crew members were too slow and rude. Most of the times the registers were empty, while hundreds of customers were waiting in line, and it was impossible to get a supervisor. Despite being in line on time, I missed my freight, plus a some customers who were ahead and behind me.

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.

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Small seat space for 13 hours flight, they charged for baggage , very bad quality of food,

About an hour delay but we made it to Chicago. I feel that the smaller connecting flights are the ones that cause the delays on the bigger planes that fly international.

The food we received during the flight was excellent. The service was very friendly. Definitely the best value for the money when flying across the Atlantic.

Everything was very good, except that the plane was an hour and a half late

Light and recline did not work on my seat. Very uncomfortable and could not read in the dark

Bad experience; they are not good anymore. They charge too much for luggage seat are so uncomfortable, Flight delays which may miss your next flight, they don’t care if you miss the flight or not. Zero customer services for front desk representatives Istanbul's airport I’m not using this airline any more.

This flight was in the air when the national power outage happened on 28 April 2025 in Spain and Portugal. As a result Lisbon airport was closed and the flight was diverted to Porto. There were no phones, internet or ATMs working and the Turkish Airlines ground crew in Porto were trying to find alternative transport to Lisbon (by bus). This did not materialise until late in the evening. The Turkish Airlines ground crew suggested that passengers may find their own way of getting to Lisbon. That in itself is a failure of Turkish Airlines, but understandable as there were no means of communication. The Turkish Airlines ground crew also said that any expenses insured for travel to Lisbon will be refunded by the Airline through their website. Unfortunately, I could find no way to travel back to Lisbon other than to hitch hike with an Uber driver. Because no systems were available and no credit card payment possible I paid the driver 140 Euros in cash with no receipt as systems were down. I arrived at my Lisbon hotel at 23:30 (flight was scheduled to land at 12:30). Upon contacting Turkish Airlines for compensation they are not willing to do anything as I do not have an invoice for my expenses. They do not even consider the 10 hours of delay and inactivity on their part as a reason to provide any sort of curtesy towards me. I find their behaviour appalling.

The flight attendants were great! The seating for business class is better on other airlines. The food was also good!

The Etickets had been changed (Why?) without notice ; Hence, that caused troubles when checking in. Not until I contacted my ticket agent and was given correct Etickets could I then check in.

While we were picking up passengers in São Paulo, on our way from Buenos Aires to Istanbul, it was impossible to use the bathrooms for 90 minutes. The crew was largely inattentive with one or two exceptions. They should distribute more water for a flight that long. When I signal that I wanted to have a second glass of wine, my prayers were left unanswered…
