Terrible. Delta delays caused us to miss our flight and they did nothing to fix it.

Terrible. Delta delays caused us to miss our flight and they did nothing to fix it.

The A330-200 was showing its age but otherwise this was a pleasant flight with friendly crew. The meals/snack provided were pretty good.

The most unprofessional and disorganized experience I’ve ever had with an airlines. After the flight was diverted on the runway and we returned to the gate, there was no communication about the plans and it took an additional 5 hours to get set up with a hotel and a new flight, information that was not readily given to the passengers and mostly gotten second hand from what other passengers heard from each other. Based on this experience I cannot recommend flying delta again

I wouldn't say I liked being forced to check my small roller bag at the gate; too many people had bags and were in a higher boarding group.

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,

The boarding agents appeared to do the minimum customer service. They did not appear to try to find solutions to problems.

715PM departure was 2.5 hours late. Received hotel & food voucher but after we already booked a room. Entire team just seemed like they were 2-3 steps behind in execution, and notifcations.

The only real hiccups in the flight were things beyond Delta’s control - turbulence which delayed food service and a departure delay caused by some VIP plane which stopped all departures and landings for 30 minutes - and was never explained to us by the crew. Otherwise good flight. I would fly Delta again.

Checkin was easy, boarding was organized, employees friendly and nice. Was a lovely flight.

I understand why there was a 40 minute delay, but we should have been offered snacks during that time. We weren’t offered it until later.

Delayed by almost an hour - I also noticed that all JetBlue flights departing from PBI were delayed yet the weather was perfect.

I loved the wifi, much better than Delta. Seats were old. and bathrooms dingy.

There was no wheelchair or wheelchair escort at the gate..unacceptable

Delayed 4 hours because of maintenance issue they knew about all day. Get another plane. Time is precious!

I liked that boarding and take off were timely despite a 15 minute delay due to weather. The pilot communicated with us the entire flight keeping us informed re: turbulance and slight delays on the runway after we landed.

Has been always great except flight cancelation in the past at very last minute waiting till 2am and we when have to beg for overnight accommodation

There were weather issues and coding problems whatever those refer to, but JetBlue, for two days in a row was unbelievably late. Several hours late, resulting in almost no sleep for passengers like me.

The plane was very hot. There were delays . Generally, the flight was great.

If jet blue is going to offer tv at every seat, fix the headphone connection so you can hear. Haven’t had a usable headphone jack in years

Plane is old and seats are worn. Add to it the plane was dirty. No plugs for laptop.

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

they made me check my carryon. There was space in the overhead bins.

The plane was delayed 2 hours. The wifi did not work. The seat in first class was not comfortable because the bottom felt like it lost all of its padding. And I did not like when the flight attendant made me wait at my seat to use the bathroom and didn't tell me why. If there were too many people using the 1st Class bathroom, she should have told me to go in the back, coach bathrooms. I guess I have to feel fortunate that they found 2 local pilots to still fly the plane tonight after the original pilots ended up at an airport 60 miles away due to high winds.

The crew were really great, but the 4 hour delay in small chunks was the worst.

Flight canceled due to weather. Rescheduled flight canceled due to maintenance. I’m stuck!

You could have been ON TIME! And I was miffed because I spent an extra $82 to get my seat and the steward put a woman from the back in my aisle for nothing because her movies wouldn’t work. I’ll try that next time and save $82!

Again a nearly five hour flight and pretzels is all the food you get and all you can drink water. No electric plugs in economy. Staff was totally not caring. Delta next time

Needs a lot of improvement to say the least. Majorly disappointed after the service we experienced on both the Japan and China airlines.

Just a crappy airline. The same every time. You feel you are a cow on a farm. You are being being whipped and pulled.

Wasn’t very crowded. Seamless processes. No issues traveling with two little kids.

Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.

Delayed abs delayed Gate crew giving poor info - we are definitely leaving at —- Ultimately to cancel flight after 4+ hours of delays Just cancel it earlier

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Everything was on time; the flight attendants and the gate personnel were very pleasant and helpful.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Perfect flight. On time departure and early arrival. Smooth flight.

Awful! The flight was delayed and we sat on the plane in DCA for an hour because fuel was out in the wrong part of the plane and would not be accessible during flight. So the plane had to be refueled in correct tank. They also allowed someone to get off of the plane. This delayed my six hour flight by an hour and made me miss my connecting flight. I ran to new gate and American Airlines agents new about the delay and even knew that I was trying to make the connection. They knew thru communication with my friend while in flight that I was in the airport and running to the new gate and they still closed the gate and refused to let me on the new flight despite plane still being at the gate. It was horrible and I had to be rebooked on a flight for 24 hours later. This has been a nightmare and if American Airlines can cause customers to be delayed and then have zero empathy as having an on time flight was more important to them than helping a customer who was delayed by no fault of her own, then it's seems that it's not a company that I want to continue to give my loyalty to. I'm so disgusted.

Help was available but timing was bad in my case

It was a horrible snow storm, but updates were inconsistent and the app never displayed a remotely accurate time or gate until very close to boarding.
