Great people making you feel great and pointing you in the right direction always

Noting this only because it’s so unusual for delta: this was just an uncomfortable flight. The jet ridge was too hot and the plane wasn’t any better. By the time we got off the ground the AC was on but for such a short flight it was almost too late.

1) It was extremely hot in the cabin. All the passengers were sweating and it almost became suffocating 2) It was a 50 min flight but there was no service. How can a 50 minute flight not have any drink/snack service?

Very bad multiple confusion and miscommunication which i ended up missing my flight.

Got to fly my favorite plane, the Boeing 767-400ER, to Milan. The soft blush pink mood lighting during meal service was very beautiful and gorgeous. The service was top-notch, and our flights were on time. I highly recommend Delta.

With Aeromexico it ended up good but with Delta it was bad because we did everything through Delta... Showed up at the Delta terminal... It was the wrong place! Nothing ever told us to go to the Aeromexico terminal. It said "in partnership with Aeromexico" but I was never instructed to check in with them or go to their terminal. We had to haul @$$ running through the airport and almost didn't make it thanks to this poor communication. 👎🏽

Delta canceled our flight and we had to scramble to find another airline to get home. Phoenix is not a delta hub so they didn’t have another plane. It would have been a red eye though Salt Lake City. Getting in at 5am. No bueno.

There was no problems, just a little uncomfortable with seats that do not lay back a little

Only not having an assigned seat was an issue. Rest was great

Delta is a premier airline so my expectations are most always met.

Our flight delayed, due to the incoming flight arriving late from Paris. AF caused us to miss our connecting flight, also booked through Air France directly. They couldn't accommodate us until later that night, and we had to be in AMS earlier than that. They won't do anything else to help us and wanted to charge us more money to rebook us too. Not great service, since it was all their fault.

Seats! The eternal problem in economy. They are like stones!!

Everything is good except the seats are tightened no rooms for the legs,

The plane's pilots, including the captain himself, thanked me for the flight. I know it's just marketing, but it was really nice to see these people. It's a great idea. Airplane food is never "good," but the entire crew and flight organization were top-notch. I really liked Delta, and I think I've traveled all over the world, and that was something new for me. Maybe even the old planes, the B767, but next time I have a choice, Delta will be my first choice. Thank you, a satisfied passenger :)

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

It was an OK flight with below mediocre service by their flight attendants

Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.

Not great , just ok . I expected better food but it did not deliver . Flight staff was ok . The guy at the drop off bag counter was the only saving grace in this whole trip . He was pleasant, friendly and very helpful . You couldn’t ask for a better assistance from him .

Gluten free snack options and meals that offer both gluten free and dairy free.

First class ticket gets you no seat back entertainment? I have to bring my own laptop to see a movie? And most of their movies have ADS? No thank you. Worse: Tiny snacks only on a 2 hr flight?

We purchase first class seats for the first time for multiples of standard economy ticket. There was no access to the club lounge and no priority boarding. The meal and the service once on the plane were superior and the seat was nicer, but not worth the price difference. I will be happy to seat in economy and spend the difference on more travel.

I upgraded my seat and was promised it would be next to the emergency door for extra leg room and they said it was premium plus but it was at the back of the plane...same thing happened from Newark to Dubai

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

The woman gate agent in Phoenix was none too sympathetic about my check-in process as I am relatively new with using apps. I almost did not get on because she said I did not check-in. I thought I had via Kayak where I purchased a very expensive ticket. Lesson learned but to be told I may not get on as a matter of factly was difficult to hear.

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

Awful, rude staff. Their abrasive comments are unnecessary. Most seek a frictionless experience and will cooperate if you ask. Additional childish bullying of customers is not acceptable or tolerated. We had the same problem with our departure flight. We will never fly United again.

No cooked food. Crew was not friendly and not that helpful

It is ridiculous that Lufthansa weighs your carry-on bags. It's also ridiculous how strict they are about the 50 pound rule when you're flying overseas for nearly 3 weeks. The reality is, that if you book a business or first class ticket you get a $70 luggage allowance. It's bullshit that it's not about safety. It's not about regulation. It's about money. And that pisses me off. Furthermore, under price, which I assume was the travel consolidator for my ticket sold me some bullshit ticket that did not include to check luggage. What a bunch of nonsense. That's a scam. There shouldn't even be a ticket offered to Europe without checked luggage. I don't know how most people are, but now I'm gonna be very skeptical about using KAYAK again and flying Lufthansa. I think maybe it's best I just booked with the airline directly.

The tv and remote didn’t work. The plug to charge our phone didn’t work.

I have very bad experience with United because Vince two weeks that I did not receive my luggage yet

The crew could deploy more customer focus and not frown when asked a question. I’m speaking of one lady in particular who raised a hand in my face for me to wait whe I tried to ask a question and never came back to me. Very unprofessional and rude.

Boarding procedure should have the crew and personnel who are more trained, in a sense of precisely knowing what can be done and what cannot. They do not have the exact information on what you should do in the first place, also the boarding itself was slightly delayed due to the aircraft "not being ready".

..it was short.. I didn't like that my red bag went out completely stained with black stains..That's probably some airport staff bad handling but still

Seating was average for a first class seat. It very modern. I expected better.

There was more leg room than on the overseas flight, which was nice. Boarding was very well organized and the flight very comfortable.

The flight was delayed and I would have missed my connection so I had to be rerouted on a much earlier flight.

I had to rebook my flight or I should say I tried to rebook my flight and all I got was a complete run around. The response to my first call/request was "call back on the day of your flight". My second call/request was more positive and I was told that yes flights/seats were available for the dates I requested but to call back the next day as the price for the flight would drop. I called back the next day and was then told there were no seats available for any of the dates I was requesting which covered a period of all of April, all of May and all of September. I knew then I was getting a run around. I called my CC company and submitted a request to stop payment. They have done so. I will never, never book through KAYAK again and will never fly with Lufthansa. Finally, I am a seasoned traveler and have lived and worked overseas for most of my life. Never had such poor service.

Entertainment is nonexistent. Food might have been good, however due to language barriers I didn’t get to have any food. Flat bed seats and layout was excellent. Crew efficient and straightforward, but lacking any western style approach. Not that I’d expect anything else, but one could have hoped.

Flight took very long to even get checked in for, everything was late and written out by hand. My luggage was lost for several days and it was the most unorganized flight experience of my life.

It's the shortest trip one could get from BEG anywhere, so it was fine.

They had lost my ticket and despite showing them the confirmation email with the itinerary and receipt of payment for the flight they could not put me on that flight and rescheduled departure postponing it by a whole week

Kraljevo is very convenient airport. It's brand new, small.and efficient. Great job!

Plane was late causing me to miss connection. Flight the next late causing me to miss the rebooked connection. Air seberia I think is more late than on time

This was my connection flight that was moved time ahead for a almost entire day so I lost it and I had to purchase new ticket once I landed in Copenhagen since nobody wanted to take responsibility for moving flight in that way so it’s impossible to make it. Very poor job by Underpricer, Air Serbia and SAS.

I purchased an exit row seat and priority boarding, about 3 months in advance. Without any communication whatsoever, my seat was moved to row 2, when I checked my reservation 2-3 days before departure. As no exit row seats were available anymore, I selected a seat 1C. However, once at the airport, I was issued maybe the worst possible seat, 29E, middle seat, one row before the last. It is not worth my time to request the refund on the ancillary purchase, I am simply done flying with Air Serbia. Also there was no boarding process to speak of at all, or online check in.

Lacking online check in, had to wait an hour in order to check in on the counter even without language.

Seats are very small and uncomfortable so such a long flight. My tray table was broken and taped up. Flight attendant untaped it to put my tray on. I taped it back up when done. The armrest between seats was broken and metal exposed. I will not book Air Serbia again.
