A 6hr delay is going to put a damper on all reviews. It was almost impossible to get into the Delta club also. Zero conveyance. I could not use my status for anything. Makes me wonder why am I loyal to delta?

A 6hr delay is going to put a damper on all reviews. It was almost impossible to get into the Delta club also. Zero conveyance. I could not use my status for anything. Makes me wonder why am I loyal to delta?
I fly coach so there is always the feeling everyone up front has more space than me. Everything was fine - on time which is the most important thing!
Great overall experience and use of the Delta One lounge was amazing!
I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(
Bad. Flight was delayed due to maintenance issue with Delta. Seats were small, no service, bag got broken on initial flight. Cramped and hot. Sitting inside with no ac.
No snacks not been water was offered I fly weekly and have to select Economy or extra comfort per business rules but will choose American at least they offer mid seat class passengers water. on short flights. The WIFI was awful on the plane as well. The thing I can not figure out is why you treat business class people this way we spend more money that your one trip first class passengers cumulative than others maybe look at the company name of the people flying and treat us better as there are thousands of us flying weekly and choose what airline we want to select.
The boarding agent guy in Lexington on 7/23 that boarded the flights to Atlanta is very rude for working in customer service. I know there were delays but he was dismissive rude and arrogant. Most native Kentucky residents are nice and very cordial he needs to eat a big ole piece of humble pie. I watched him be rude to several people and as much as he could of filled up a delayed flight to save you money and he was so rude to people it was ridiculous. Next no water or snacks on short flights is awful 1st you delay a flight then do not even offer water on the flight.. No thanks I like delta better but I travel ever week and to be treated like this might as well fly American at least they offer water and have better rewards.
The staff was fine. The plane was extremely tight, and I paid for the wifi and it did not work at all. I was actually going to ask for a refund.
Left on time and arrived early this extending our 31 minute transfer. Bags made it also!
The crew was very polite as I have a few handicaps and everything was made pleasant. Check-in was easy as I was brought on board by the wheelchair assistant. One flight attendant did make sure my personal item was carefully stored under the seat in front of me. I was made to feel welcome as a customer as I made my first trip with a few disabilities. Entertainment and wifi worked quite well. The only food service were snacks and drinks. Those were okay. Overall it was a very smooth flight and encouraged me to use Delta again.
Tiny seat made for midgets. You can’t put a normal size human in such a tiny seat for 8 god damn hours! Hot plane, no air. Lost bags at Rome airport for 8 hours, lucky to have found them. Horrible flying experience, United Airlines should be embarrassed!
The issue is the flight is delayed, which causes me Missing the connecting flight by 3 mins. Remember the connecting flight is a US codeshare flight so UA should be able to inform the operating airline about the delay.
Seats are made for children. An 8 hour flight with tiny seats is more like a cattle car. Lost bags at Rome airport caused a 7 hour delay.
We sat on the tarmac in Denver for over 30 minutes because a plane was in our gate. The pilot kept saying it will just be 5 minutes or less. However, we sat for over 30 minutes. Experiences like this make customers not trust what the pilot is saying.
Waited on tarmac for approximately 15-25 minutes before taking off. When landing, the time it took to taxi to our gate was the also 15-25 minutes.
Waited on tarmac to take off for approximately 15-25 minutes. When landing, the taxi to our gate took a similar amount of time. This happened on both of my United flights.
The plane was so old. I paid a ridiculous amount to fly business and there was no internet for six hours! This can't be happening in 2026 and especially in cross country flights where there are a high volume of business travelers.
The first leg of my trip the Republic Airlines aircraft was late due to a maintenance problem. Then I called United to reroute. Their reroute airline lost my bag but found it and returned it two days later. Hopefully my return trip home is better.
The male air hostess was rude and didn’t provide good customer service. Didn’t even offer me a drink
This trip was a Christmas gift to our family. We were flying from Lexington to Palm Springs. When we were checking in the ticket agent said one bags was over weight by 4 LBS. We were flying first class which has baggage weight of 70 LBS per bag, one bag was 54LBS. We then had to take items from one bag to another. The agent also saw we had a dog with us. Once on the plane we were seated with the dog in the carrier. The United ticket agent came in the plane with two other people, I believe one was TSA and the other some security officer. The United agent said we had not paid for the dog ticket. We had paid for the ticket when we purchased our tickets. She did not give me time to find the email receipt. She then threatened all three of us with either I come with her or she would have all three of physically removed from the plane. I left the plane to pay for another ticket. She had to take my credit back to where we checked in. She acted as if it needed to be done immediately. She said we had 3 minutes. We then sat at the gate for approximately another 45 minutes. This was so embarrassing…to be threatened to be removed from a plane that we paid for all tickets including the dog. The flight attendance on the next leg of our trip were not very attentive to the passengers. On the plus side all the flights were on time. All in all, this was a miserable way to start a holiday vacation. United Airlines showed no compassion towards the whole incident. I feel we were purposely neglected.
Seats are getting smaller and smaller. In flight movies are poor compared to other airlines. Food is mediocre.
Ultimately fine but plane seemed dated and creaky and landing was hard…. At no time did I feel unsafe so thank you.
Better perks for corporate employees whom travel often and spend a lot of money with the airlines. Snacks were terrible chips crackers are ideas. Flight and crew were great comfort was fine entertainment not so great so so called status members means nothing
Flight had mechanical issues and it was delayed 30 mins - some of us boarded and then had to deplane.
Delayed flight. Missed connection, AA put us on a later connecting flight. The connection flight was delayed 4 times and we had to deplane. Didnt get home until 3am, when I was supposed to be home at 8:30p. Zero compensation offered from American. I would not fly them again.
Better snacks but flight and crew were amazing on this flight
The AA app really sucks ... Every flight & connecting flights were delayed over 30 mins. One connecting flight on American Eagle said it was delayed in its arrival ... when it was actually parked across from the gate for over 1 hr before they pulled it to the gate. Seats in the economy/ main cabin are packed together like sardines ... no leg room.
To start, I’d like to say that every American Airline personnel I interacted with on the ground, especially flight crew, was very friendly and did their best to help me out. Despite this, however, my experience with the airline was an entire mess. The 7:19 PM flight was heavily delayed due to weather, and pushed to 10:30 AM the next morning. Because of this, I had to spend the night inside of the airport. At some point later in the night, I got an email saying that the flight had been canceled. I called the support number, and the representative on the other line told me that the flight was still on and that I didn’t need to rebook. The next morning, no one came to the gate to open the door for the crew until almost 11 AM. By this time the flight crew had been waiting for over an hour, and they had called management to get someone to open the door for them multiple times. Around 11:30, the gate screen had changed to a different flight. I ended up buying a last minute ticket with Southwest airline just to get to Chicago, because the next flight with American wasn’t until 7:19 pm that day. Now, earlier that morning my suitcase had been sent ahead of me to ORD. I went to baggage claim to ask them if I could have my suitcase forwarded to where I was staying. The representative at SDF baggage claim said they could and put the claim in for me. As I was going back through TSA, I got an email that the airline had found my suitcase, but the next step was to send it BACK to SDF. I called the airline support number again, and I made it clear that my suitcase needed to stay in Chicago and to not come back to SDF. The representative told me that they would hold my suitcase at ORD and that it wasn’t going to be forwarded anywhere. Once I got there, I found that they had loaded my suitcase onto a plane to send it back to SDF. Thankfully, I had gotten to the baggage claim counter in time for them to put in a request to bring my suitcase back up. My refund with the airline is processing already, but because of this entire experience and miscommunication at every turn of the way, I will not book with American Airlines in the future.
Cabin was roomy enough to easily slide my carry on under the seat in front of me!
They needed to de-ice the plane. Apparently airlines have a problem keeping their de-icing vehicles in good repair. After we backed away from the gate we sat and didn't move for nearly an hour. Nearly an HOUR with minimal communication from the flight crew. Eventually the sun took care of what American Airlines could not and melted the minimal ice. We finally took of a hour late which, in turn, jacked up our connection in Chicago.
Boarding was a little chaotic. United checkin staff was truly excellent and saved the day for me. Food was great. Comfort so so. Flight was good
The flight and staff were perfect. No notes. Amazing experience overall.
I'm a nervous, autistic adult. The staff were very friendly and answered my questions and came by at regular intervals to check everyone's comfort. They even resolved a fight between two couples in front of me!
The new buisness class pods are 100% worth it. Loved it.
Pretty bad. No welcome drink (the Lufthansa signature drink they advertised but did not serve). No 2 round of beverages. No coffee to end your meal. No snack before landing on an overseas flight. Mediocre everything and unattentive staff. Munich and Frankfurt as connecting flight airports are terribly big (20 min walk for transfer!) and confusing. Will not fly again.
My premium economy experience did not live up to my minimum expectations. I've taken this flight twice in the last three weeks, and each experience was the same. The premium economy seat was worn and extremely difficult to recline. It took two people to return it to its takeoff and landing position. The food was OK, but for the premium that a premium economy seat cost, I expect a satisfying meal. Years ago, I looked forward to the experience of flying transatlantic on Lufthansa (I especially enjoy the hot towel before the meal), but this is not been my experience recently. I'm not going to use Lufthansa again.
If was mostly my own fault. I booked and paid for a window seat. That was a mistake for a long flight. It was hard to get up and use the bathroom. The entertainment system seemed primitive for a modern aircraft.
It was a safe and smooth flight. Members of the crew at the second level, business could have been more polite and engaging.
Our seats were not together - one on upstairs business class, the other nicer downstairs business class. Terrible!! A very nice agent worked hard with other passengers & got us upstairs together. Not ideal experience. Check in agent should have caught that! Asked about upgrade to first class for additional $2500 each. Refused upgrade saying we upgraded once already. We booked on business class to begin with so we’re NOT happy!!
Old planes and rude crew. They need a make over and better staff training. Even business class crew was rude and the hospitality was non existent.
My baggage (1) didn’t arrive with me. I am waiting for it.
This is just for first leg, second leg from London Heathrow to Delhi was the worst.
I have flown on British Airways, many many times and will continue to do so! Always the greatest service and staff!
canceled flight. needed to fight to get same fare class. now they have canceled return.
I really enjoyed the flight…and food and the hospitality but didn’t get the food I requested for.
The plane was ancient, and its technology was in disrepair. None of the charging stations worked, and the screens were barely functioning.
It was my experience w Kayak that was negative. I’m never using kayak again
Flight was delayed 4 hours, gate change was a big trek the opposite direction, gate agent indicated a lack of faith that we would actually fly.
I washed attendant for assistance and she never got back to me. I asked her a second time and she said she would check. She never did. The flight was over an hour late taking off No food service was offered despite over 4 hours on the flight
I chose seating based on me being 6’3 and they changed planes I guess bc I got 2 random Seats that were middle and window and vert cramped and uncomfortable for a long flight….should have been able to get same seating just different aisle maybe especially since we picked them and weren’t random
