This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

Overall, terrible. Flight from SFO was delayed due to “air traffic control issues”, and we were all mislead about connecting flights. Told “you have 20 minutes to catch your connection”. Reality was 5. We got to watch the plane sit at the bridge. Won’t fly Delta with a connection again.

The crew was very kind and always smiling. The seats were great and I was very comfortable during the flight. The only thing I didn't like was that the lavatories got really dirty at some point during the flight. Other than that my experience was great

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Everything was great. Great service, excellent communication, and early arrival

We were forced to wait nearly 50 additional minutes before leaving the terminal.

Delta flight attendants poorly managed the boarding process and overhead storage. My bag was checked last minute and no claim ticket was provided. My bag is now lost. Complete incompetence by all flight crew involved.

Good and consistent Printer in lounge did not work for me :(

Flight did not have seat back entertainment and the wifi was iffy.

Change cabin crew assisting business class. Not taking care, ignoring requests and calls. Never had such an experience in business class.

The flight was delayed so the people from a late connecting flight was able to still make the connection.

The crew was outstanding. And the food was surprisingly good. The chicken and the pasta dish were both delicious and I was supposed with a pizza twist near Landing. We hit a lot of turbulence and the crew was calm and kind. Loved the TV in screen. Tons of new releases.

My flight was completely full. Making me very stressful with people walking around all the time. I believe airlines can do better for entertain people during the flight.

Haven’t used United in a while. Was surprised with the free blanket and earphones. Service was great. Huge plane. 9/.row.

Ridiculously slow disorganized boarding, ended up 35 min late and people missed connections

The Cree was BEYOND AMAZING. They were, by far, THE BEST CREW I had the pleasure of flying with. They catered to my every need, beyond friendly, and upheld the highest level of professionalism that is of Lufthansa Airlines.

Really solid flight! The in-flight entertainment screens are not very touch-responsive in the way that of other airlines’ are, which was my only issue. But otherwise we had good food and drink offerings and the flight attendants were very welcoming.

The incoming flight was delayed so boarding didn’t happen on time. Upon landing in Munich, we couldn't pull up to a gate so we had to disembark on the tarmac and be bussed to the main terminal. This caused a mad rush for me and others who were making connecting flights to get to our new gates, and my bag didn’t get over to the new plane in time.

Great crew, boarding and deboarding excellent. Seats too close together. The 5'8" woman seated next to me had her knees pushed into the seat in front of her. The meat was very tough in the dinner...

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

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.

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

I didn’t like anything, being platinum pro get you absolutely nowhere and does not increase the customer service treatment whatsoever anymore. My flight was canceled and they put me on a flight eight hours later that would’ve got me back in the middle of the night. They could’ve easily move me up to an hour Prior on an earlier flight. My second flight was unreasonable to take, the third flight was also canceled due to mechanical issues like the first flight. I don’t know what’s going on with American, but they are falling apart, after seven flight changes I finally got home, Unreasonable.

One of the best flights I’ve had. So smooth.

I never have a good experience with American and this was no different. The airplane was INCREDIBLY hot. Like unbearably so. Everyone was fanning themselves with pamphlets and sweating. When someone asked the flight attendant to turn down the temperature they were told there was nothing the crew could do. Once we pushed back from the gate we then had to wait an hour to take off and the communication from the crew was not good. People were getting up this whole time and a man was even in the bathroom when we took off. Once we landed at our destination we waited another 30 minutes at the gate to deplane with, again, no communication from the crew as to what was going on.

Airlines must do something with overweight people... Maybe reserve a business class seat for them, or you could pay the consequences if someone overweight seat side by side to you in economy.

They could have done a better job announcing the boarding groups and asked for more drinks (water) if needed.

Fantastic. I am low vision and was impressed with how helpful and accommodating the service tam was. It was super appreciated! I was pleasantly surprised about how delicious the food was. Like, “I wish I had more even though I’m no longer hungry” delicious. 100% enjoyable trip.

Flights were on time both ways, such a big plus! Staff was very accommodating and friendly. Question the choice of snacks that, which on both flights was dairy based. Appreciated using bottled water.

This is one of the best flights i had. Good boarding, good seats , good food, and nuce stuff and clean toilets I took the Tourist upgrade and indianischer food , the best.

I like the service and the efficiency. I am lactose intolerant and the lactose intolerant meal in business class was not astounding. Also, the business class fully reclining seats are not that comfortable.

Food was great but they didn't clear my meal tray for 3 hours. You'd think they could check though the cabin now and then.

Upon arriving at IAH, it was informed that the luggage had not arrived. Still waiting to hear back when it will be delivered.

I wasn’t allowed to board with my children. I was charged outrageous costs for basic carry on size luggage. The entertainment screens were outdated and not user friendly.

I was very happy with everything, thank you for the smooth flight ✈️

Overall excellent service and Frankfurt Airport was very efficient and clean

I’m glad the bus waited for me to connect me to my next flight since we were delayed. Flight was good.

Entertainment system is old. Food can be tastier Need to provide toothbrush and toothpaste at least when asked.

I pre-ordered my meal and did not receive it. The seats are very old, uncomfortable and dirty. The crew was excellent and made my stay on board comfortable and enjoyable.
