I usually have a positive experience with Delta. Complimentary upgrades are always nice!

The pilot was excellent - he flew us around a storm and even though predicted it would be a bumpy ride - was able to avoid all turbulence and land us safely with only a 15 min delay. Kudos!

Great flight crew, easy boarding, delicious snacks and spacious seats. Love flying delta - worth the price.

Delay at gate caused a flight change for our connection, hotel stay, and lots of standing and waiting in lines which hurt my feet and was unpleasant as people were grumpy and yelling. Delta worker Nestor Espinosa was very helpful! Others were apathetic (tired I’m sure!) but weren’t clear with instructions and didn’t give both of me and my travel partner the same food voucher etc.

From boarding to the next 45 min to 1 hour, it felt like a sauna, felt like vents were working but no AC on.

TERRIBLE, THEY ARE THE MOST DISORGANIZE AIRLINE A HAVE KNOWN

I was traveling with my 85 years old grandma and 60 years old mother. Which I requested to get a wheelchair. I went to the Delta Kiosk and asked for a wheelchair.  They brought a wheelchair and 2 minutes (without exaggerating, time is important for me as I am well disciplined with a military background) later they said that the wheelchair belongs to American Airlines, so we need to switch it.  We were like where is the other one so my grandma can use it? They are like, "it's on its way, she has to wait for the other one" I asked them why does she have to wait? Is it ok for her to sit on this one when the other one arrives. Answer was "NO". I guess lack of common sense was the issue. I started to explain to the agent that she can not stand still or wait. Finally, someone said that in spanish "she can not stand, let's wait for the other one" . Delta's wheelchair came, without an attendant or helper. They brought that wheelchair and left it in the middle of the airport. Nobody seemed to care. I had to push her to the gate. Then they finally realized that "wait a minute, there is something wrong with that". So they send someone, who later started harassing us, to tell us how he works for cash tips. Then a "Private Security Interviewer" approached us. I think his name was Carlos (His descriptions - tall for an average worker, ginger curly hair, wears glasses, overweight). He did not represent himself. All he did was show his badge for two seconds and when (later on) I asked him what his name was, he said "I already told you at the beginning". At that point we were waiting to be called at the Delta Kiosk (this is prior to the Customs first check in point). So, Delta Airlines hired "Private security interviewers" to make sure that nobody brings anything illegally to the US. Which is great, makes me feel safe and secure. But, it does not serve the purpose. Let me explain to you why. These interviewers do not know what they are doing or saying and you can clearly see that. They think that they are CBP or Immigration officers. They will get angry If you ask them any questions. Then they will put all these stickers on the back of your passport like they caught "Pablo Escobar". At one point I was sarcastic and told the interviewer that "I like those stickers, It's my hobby and I am collecting them. Can I have more of those?"  and interviewers eyes and brain goes like "error 404". He did not know how to react or respond to that. Then he flags my itinerary on his iPad. Trying to give me a hard time since I asked him about his name, so I can call him by his name. But of course that did not change the fact that his lack of english made everything even harder. After 45 mins of wait and clearing the "Private Security Interviewer" you would think that we are going to be all set to depart. I was wrong. We waited in line to go through the security line, just like other citizens. No wheelchair, disability, seniority etc were important for her. They treat us like she is in her twenties.  On several occasions they forced her to stand up. She was like "I swear to God that I can not walk, my son I wish I could walk, but I can not". They did not seem like they cared. Then finally they realized that she is legit disabled. They let her pass on a wheelchair. At the gate, Carlos showed up to make sure that I am going through the secondary check. They pulled me to the secondary check. And started asking me about my luggage. My response was "I only have one carry-on bag, to make everyone's (including my life) life easier". They asked the same question over again "Sir, do you just have only one bag?" I replied saying "Yes". She did not believe me and said "Just only one". So, I thought she did not believe me and I said "Yes, Si, Si, solo uno". She looked at me and then turned to the agent (Carlos) and stared at him like "did you not ask him about his bags, did you not know that he only had one carry on?". I am sorry to say that but they just looked like a bunch of idiots who do not know what they are doing. Finally they released me after a minute of secondary check. Meanwhile everyone is boarding and my grandma is waiting on her wheelchair. Then we approached the gate agent and I asked her if I could sit next to my family, if they had any seats available. She replied that "I can not change any seat at the gate, I do not have any authority". I replied "I understood". We got on the plane last and I asked our flight attendant if I could change my seat to be next to my family. FYI, their seats were 10 B and C, mine was the 35 D. Meanwhile there were empty seats on 10 D and F. Even flight attendants surprisingly said that "why did she put you all the way back, while we had 1/2 full flight. I will go and ask her". Our flight attendant was great and he made sure that I am next to my family. He went above and beyond and he gave the closest seat to the. Flight was good. Delta Airlines failed to bring the wheelchair when we arrived. Excuse was "Gate changed, that is why". I walked outside and grabbed an empty wheelchair. I put my grandma and brought her to the Customs. Then a Delta Airline worker approaches me and says that you can not move this wheelchair, it belongs to the gate. We will bring you a new one. A CBP officer heard our conversation and jumped in and said, "wait a minute you want her (pointed my grandma) to wait here while you bring her wheelchair?". He (delta worker) responded "yes sir". But when he talks to me, no sir, nothing. The CBP officer goes "Nope, she is not waiting here and I will make sure to pull her wheelchair". If that officer was not there we probably would have had to wait and be forced to change the wheelchair. The CBP officer, again the CBP officer, not the Delta employee, pushed our wheelchairs to the gate. Sincerely,

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

long flights are never truly comfortable but the airline did their best. crew was great and the flight was safe.

The captain was amazing and kept us informed throughout that there would be some rough air. The flight also got delayed but we were able to actually leave on time, which was great.

Boarding - It is unclear where the line for the group are given the signs. A solution would be a diagonal arrow pointing to the lane in which the lane for boarding of a given zone should form. As it is now, you are guessing which side of the pole the "zone 3" sign is telling you to form the line. Inflight Entertainment - The Spanish subtitles function didn't work for movie watching (in fact, all subtitles didn't work), so was difficult to follow along and I watched the movie in silence without words.

An hour-long wait to check in, 90 minutes for luggage to come out, lost luggage, chaotic operations

Aeromexico es siempre una buena opción, relación precio calidad adecuada!

No everybody brings the proper equipment to enjoy the plane entertainment. Then I was not able to enjoy it.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.

We were delayed an hour leaving Munich (No fault of the crew). They kept us posted on the status so we knew what was going on, but as a result we missed our connection in Chicago and the communication on connecting flights was pretty poor as we disembarked. It was already stressful and some of that could have been reduced by better communications about where to find transfers, etc.

One problem, but a serious one - the plane is built with electric windows that tint dark to reduce light. Sitting next to the window is VERY UNCOMFORTABLE as it emits so much HEAT in the face when tinted.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Wifi wasn't working on one of the UA flights after boarding.

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

Good movies, iffy pay WiFi, food ok- on time though and that was great!

Delayed 6 hours! finally able to board, then had to wait 45 minutes for the plane to fill up. Mid flight when food service started, they had nothing to offer with the exception of chips and cookies. Worst flight ever!

The priority seat are great especially the first row! Crew was very cordial and helpful, airplane efficient, the departure and arrival was on time.

Ridiculous fees for seats and restrictions of 10kg carry on. Cheap a$$ airline

I had a flight before this one and I was able to get to the plane, the doors were open and they didn’t let me in. It was still 15 min before departure and the plane was there with the doors open and the hall as well and I went all the way there and they didn’t let me in. Then they tried selling me another flight 4 times more expensive than what the original cost and with a 7 hour layover in a different state when my flight was direct and cheaper. Very disappointed, specially with their 0 flexibility when it comes to travelers with multiple connections.

They not allowed to bord flight, arguing that was cancelled the flight reservation. No chance to find and explain answers, very bad treated by Airline staff… At the end we buying a flight ticket with Aeromexico. Is a low Price Flight Company (cheap), as it is cheap treatment for customers… seme with Kiwi .com app. With we did our reservation. with KAYAK.com never get this kind of treatment.

Buen servicio y muy puntual El problema ENORME es pagar por la página de Viva Aerobús lo cual es imposible aún con fondos suficientes en la tarjeta. Eso te obliga a acudir al callcenter de la aerolínea, en donde para que te atiendan transcurren 45 minutos, y ya que se tiene la suerte de comenzar la llamada, te toma otros 60 minutos terminar el proceso de pago de los tickets o de la maleta extra que deseas comprar.

It is ridiculous that electronic checkin for under age kids can be done and need to be done over the counter. Having said so, we were requested to do the single line for this as if we never did any checkin or made services for this to happen fast. Just ridiculous. Flight delayed as it is the regular business for this airline.

an absolute joke. couldn’t even board because they sold our tickets out from underneath us. we had tickets in hand with assigned seats and they still denied boarding at the gate. i’m sure you guys won’t follow up or do anything so merry christmas.

Flight was on time Flight attendants should be kind and empathetic

Viva continues to strive for the worst airline experience ever.

Inept company. Won't fly again with them if I can help it. Plane was the wrong size and they couldn't board 20 people.

When you make the 3 Lines to board de airplane , I believe that you should make only one line first and then call the next and then last ,,, because the number 3 wait to long just standing there ,, my opinion !!!

On time, boarding was a little chaotic and with little information

Flight got canceled, made me lose my connection flight to Japan. Someone has to pay for it. It might be you guys

I didn’t like anything about the flight. It was delayed six hours and I was traveling with my elderly mother. It was a complete inconvenience. Not happy about my experience.

The flight was delayed without prior warning, first a 40 minute delay, then another 30. Flight was supposed to leave at 13:20 and ended up taking off at 14:50. Once on board I logged into the WiFi entertainment, it asked to purchase a code for 2 dollars which I asked the crew to get. They declined and said it wouldn’t work and no other explanation. Horrible experience. They even charge for water

I didn’t like anything, they were the worst airline I ever used, charged 40 dollars if you flight as USA citizen, if you want food you have to pay for it, seats are uncomfortable service is the worst

More options for snacks or drinks ( taking in consideration that a lot of people suffer from Diabetes now days

To check in, it was horrible. their charges are outrageous. too many passengers, few people at the counters
