the flight got cancelled - few hours before the departure time - no time to change

This a short easy flight. No food or drink but that was not an issue since we were only in the air for 35 minutes.

The meal tray was not usable it was completely uneven

My experience with Delta started with my luggage being found ripped open with items missing. The baggage office told me to bring the bag, and I wanted them to see how I found it. The agent refused, so I carried my bag into the office myself. The agent was nice enough to fix the zipper and gave me a red card with a number to call. I followed the steps; first one department, then the baggage department took over. This took more than two hours on the phone. The return flight was okay. The flight lead was checking her meals and then asked if we wanted anything before departure. However, throughout the flight, I had to ask for things because she was reading her book;which I have no issue with if she had been more attentive. At the end of the flight, the pilot appeared annoyed with the flight lead for not following his instructions regarding a meal he had requested; a chicken sandwichand said, "I asked for that for the flight." On the positive side, my work event in Vegas went well, and now I'm home relaxing.

Internet connectivity still seems to be touchy on these flights, making it difficult to rely on it for getting work done.

The ac must have died, it was way to hot on this flight. Boarding g was chaotic. The flight was delayed for boarding. Not a great experience.

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

Awful. There was an unexpected delay of nearly three hours because there were not enough flight attendants. I understand this is likely due to FAA regulations; but in that case, Delta should coordinate with smaller airports such as RDU to have extra flight attendants on the ground and "on call". In addition, this was the second 2-hour+ delay to Boston on this route in one week.

It was strange that the flight attendant was so adamant about having phones turned to airplane mode that he was calling out names from networks shown and waiting until they were all gone. I've never experienced that before, and after already working through an hour+ delay, it felt tone deaf. I take dozens of flights per year and have never experienced anything similar.

The flight was done by SkyWest only WIFI no entertainment center are available on the CRJ

The flight to America was freezing. The overnight flight back to the UK was boiling hot and the cabin stank of toilet or occasionally perfume, even though I was several rows back from either bathroom. Food was tiny portions. Two small pieces of tough and dry beef in random gravy with pretend mashed potato raking up most of it. Very little veg. Salad was ok. Wooden cutlery broke within minutes of using. Lots of old films for entertainment. Some new ones. Generally a bit rubbish.

It was a good experience, unfortunately my checked baggages were come late and not arrived on time.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

Flight staff and all was fine. Food always sucks on planes so nothing new.

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

I’m an EP on AA every year for more than a decade but this was a very pleasant and surprising experience. Clean and sizable plane for HOU to CHI. 5 row first class. And excellent food in first class the steak option was really good. Your flight attendants even better. Seat 5A

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

Why wasn't this flight departure scheduled eith another crew so that it could leave on time? When we arrived in Denver we had so little time between flights we had run to the connecting flight. We should received some credit for the inconvenience.

My wallet fell out of my pocket ( my fault). Staff claimed they looked while cleaning. Said they didn't find it, but was actually found in Washington DC on the plane. Which mean either they didn't look or don't do a good job of cleaning. Now I have to pay 27 dollars to get it shipped back and have no wallet for my entire vacation

My flight was 3 hours late, which caused me to miss my connection in Denver. Further, this connecting flight was then Later canceled. This required me to stay another night an hour and a half away, and rent the rental car for an additional Night. I am still waiting for United Airlines to reimburse me for the inconvenience and Expense of having to extend my rental Car for An additional Day. See attached receipt. https://share.icloud.com/photos/0f5ns2AaeIr7w6t_uH1qfPBUg

There were alot of delays without any information. First, my original flight was overbooked so I volunteered to stay back. The layover was hell, I sat in the airport for 4 hours. I was highly disappointed because no one was around to provide answers.

The flight was over an hour delayed. The problem was they had the wrong aircraft at the gate, Joe in the world does that happen?

My flight was delayed several hours, which is to be expected (American never fails to disappoint me!), but the parts that really bothered me are as follows: 1) I was unable to add myself to the standby list for another flight in the app, nor could the gate agents figure out how to help me do so (the app is difficult to work with and simply did not allow me to perform the action of adding myself to the list) 2) When I asked the gate agents to add me to the standby list, the agent said that he had added me, but I was not able to confirm that I was on the list in the app; as it turns out, I had NOT been added to the list after all. He had lied to me and/or failed to add me to the list. 3) I figured out I had not been added to the standby list when I spoke to the (rather rude, snippy, and dismissive) other gate agent, who finally did add me to the list after giving me some pretty unnecessary attitude. I understand that gate agents experience the worst of stressed travelers every day, so I appreciate that I was eventually able to make it onto the standby flight with their help. However, the app needs some SERIOUS attention!

The power outlets were not working for my row. Also felt like the seats have gotten smaller. I was in the window seat and felt like suffocated, as the two passengers next to me were tall and wide.

Delays and multiple changes in gates. In accurate info sent to phone. Worst flight in years. With no apologies or recompense.

No AC, no beverage service and no explanation from the captain. 4 flight legs in 2 days with no internet service.

No service on New Orleans to DFW or DFW to San Antonio. Also no explanation from the captain why we had no AC. Unacceptable!

I had a carry on and a personal bag. I put my personal item under my seat and on way to the seat I put my bag up. I usually close my eyes and rest as I was on call for last 36 hours. I heard very loud announcements that someone needs to identify their bag. Pretty sure it was not mine until the hostess pointed out my jacket details attached to the bag. I asked why she got my bag out. I got berated and did not want to create a scene. But this person needs to be talked to.

Other than being delayed 5.5 hours and having to get a hotel because I missed my connecting flight, it was an okay flight. No in-flight Wi-Fi or entertainment.

90 min delay for a food cart that needed to be fixed.
