The staff on board and gate was nice - a welcome change from the usual. We also arrived early, which was a great benefit, given that it takes 30 minutes plus to get bags at SRQ.

The staff on board and gate was nice - a welcome change from the usual. We also arrived early, which was a great benefit, given that it takes 30 minutes plus to get bags at SRQ.

Never got on it. Was re-routed through Detroit and am still in airports 12 hours later waiting for my connecting plane to arrive.

The landing was the worst I’ve experienced with a flight.

Everything I mentioned earlier - the airbus was more comfortable indeed and the experience was further enhanced.

Delta continues to set the benchmark for traveler-friendly service with minimal disruption and clear communication within the mainland US (coast to coast). I am consistently pleased to be a Delta customer, and this experience once again met my expectations. There was a brief delay departing from MIA due to a technical issue that required the aircraft to return to the gate. However, the situation was handled professionally and transparently. Fortunately, my planned layover allowed ample buffer time, so the adjustment caused no stress. Overall, another smooth and reassuring experience.

This was my first time flying Delta ever and I had a great experience!

I've flown several other airlines, and Delta is really on top on things.

No in flight service, no explanation - FC got service, C+ did not, unsure about Economy. No turbulence to speak of, so I guess another way to cut cost, or promote health and well being of Delta employees? Also, boarding in MEM combined zones, and with overhead space already full on both flights after Zone 2/ Diamond, presents a huge challenge to find a space for a bag. Delta, other than point A to B, is no longer reasonable to fly - very poor experiences, not even taking into account the chastising at the gate and rude crews, across the board.

Wasn't a Delta issue I don't think, but seems there was a Delta flight at each of the 2 Dallas airports at the same exact time, both to Atlanta. I was evidently booked on the one at Love Airport, but the Carey transport shuttle took me to DFW instead and I ended up missing the flight by just a few minutes. Was able to book a Southwest flight from Love Airport, but was a big loss of time and an inconvenience.

Non stop on long haul is the way to go. Great experience

It was really nice journey i personally recommend klm flight

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Empty seats next to me - wish it had been for a longer flight!!

I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

Flight was on time, staff are friendly and helpful onboard.

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

The boarding was efficient. The entertainment system was a bit unstable but Air France has a good selection of movies.

They lost my bag and I still haven’t received it yet

They lost my bag and I still have not received it

Communication on the delay, rebooking and how to get a hotel was poor. Mails, airport check-in and transfer desk said different things.

Not consistent with the food quality (I mean taste not freshness)

Safe and stable made me sleepy and I slept and dreamt 😂😂😂😂

Food was really mediocre for premium economy in comparison to other airlines… the crew was nowhere to be found… 14 hour flight…

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

They allowed me to book the flight, which took quite an effort to find the best option for us, and then 2 months later, cancelled it because they didn't think 90 minutes was enough time to get between connections. Why let me book the flight in the first place? I am somewhat disappointed in Kayak and will be choosing other options in the future

Delayed departure Madrid to Lisboa and my luggage no arrived

The cabin crew were curt, not with me, but observed with other passengers. They were unduly rude and it was unprovoked and when they realized they were wrong, they made no attempt to apologize for their own confusion.

The value is there, but the layovers in Lisbon were not great. The passport control was so bad that a 2 hour layover became very tight and on the return the Terminal was barebones which made it a long 3 hours.

Booked business with TAP from LAX to Cabo Verde - overall ok, but just doesn’t feel like business class. More of a budget airline

I was disappointed of the crew, not friendly and attentive. Delay one way for fuel leakage and the plane is so hot. Not that great all around but I’m glad I experienced it so now know better.

Poor. Our flight was delayed and they told me I would be fine to make my connection in Lisbon, I missed it. Then they told me my bag would be automatically loaded onto my new flight to rome. It wasn’t. It’s been 4 days and I still don’t have it.

Flew Business class and did not like anything, flight attendants were rude and not helpful. Food was of poor quality and I did not eat meals.

I am not very tall, and had a difficult time getting my carry-on placed in the overhead bin while passengers were behind me waiting to get to their seats. After struggling with the luggage, I turned it around, and left it, knowing it was not properly placed, but believing there was adequate room for it in the bin. When the flight attendant came through the cabin, she asked whose bag it was, and scolded me for not positioning it correctly. She turned it around and moved on. I thought that her approach was totally unprofessional, calling out a passenger in that manner.

Plane was delayed, reading the gates on their screens was horrible. They posted it a half an hour before the plane boarded. By the time I got there with my premier boarding they have filled the plane because it was over booked. Gate closed at 12:03 I was there at 11:54 plane took over around 12:20. I was told they would put me on the next flight. I had to go to TAP information desk. They didn’t give me a voucher they just said they would put me on the next flight. At the desk I was told I had to punches a ticket. The woman said buy it online because it’s cheaper. It in fact was not cheaper. But I had gotten out of the long line that formed so I paid 200$ for a new ticket. At a later flight, not the next flight. I had checked my bag and was told it would be on my new flight. I was then bumped to an earlier flight and was told my bag would also be on my flight. After landing in Madrid loosing a day in my hotel i landed without my bag. They didn’t load it on any flight that day. It arrived in madrid the next day. Essentially ruining the first two days of my vacation. I’m now seeking compensation.

Awful. They didn't even show concern that her connecting flight( Dallas to Mardrid) was gone/missing. I don't understand how that is even possible. Rudest answer from one of the crew was that American Airlines sold the tickets to somebody else. My daughter was not in the list.

Excellent lie flat seat for premium economy! Great staff. Bad food . Not so great entertainment. My bag didn’t make it either.

Bad weather Excelent pilot Spoke British 😆on time seats small ad expected in a discount airline

Boarding, crew, food and baggage handling excellent (no bags lost, yay!). However for an 8 hour flight, there were limited entertainment options. And really would have liked to have a pillow!

Plane delayed due to weather. Plane boarded, then told to unboard due to a maintenance issue.

Everything went smoothly, and we even arrived 40min earlier than scheduled, on an Orland-Madrid route.

Suddenly, I don't find my flight back on the app Help Ticket 0757345716866 Hoeflich Flight back Sunday ib5333 Ib2629 Ib4268

Great : The crew was awesome ♥️ To improve : - The rice in the "Rice with chicken" was rather s kind of rice pudding, not good at all - No power outlet to charge your phone. 😒

The food on the flight was of marginal quality. Small bits of chicken, instant mashed potatoes and some carrots. The rolls were very dry, nearly inedible. The seats were quite small and didn’t allow for any shifting of position during the flight. There was limited leg room.0

Delayed. Mismanagement of gate lines. Passengers arguing with eachother as a result of lack of organization by airline. Avoid this airline.
