As an Elevance employee, don't we get priority boarding? Also, I boarded zone 5 and could not get normal carry on in luggage space. There were many Delta employees on the flight and their bags, which were large and could only fit two bags per compartment, got preference over customers so I had to check my bag.

Everything went smoothly, WiFi connection was strong. Time to upgrade the regional planes, we are all on top of each other. No room to comfortably do anything.

The bathroom is disgustingly dirty. It looks like the crew members didn’t clean it on a regular basis. Also, who made the bathroom so small?. I am not a big girl but I still feel very cramped inside. Def unpleasant experience to use the bathroom.

My experience with Delta is always pleasant. My return flight #1426 from ATL to RIC was very delayed with departure and landing. It also took a substantial amount of time for baggage claim. It was already late at night, so the delays made for a very long day. I did not get home until after 12 midnight.

I had a great flight with delta. Plane was clean and the staff was nice, I would fly again with delta.

After flying with Qatar Airways and Kenya Airlines. Delta leaves a lot to be desired

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!

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

We left nearly 3 hours late...so that was not a good experience. We boarded and then ended up about 1 hour stuck at the gate. Not a good experience.

It is completely insane to me that first class does not include WiFi. Also does not include lounge access. Port for phone charging did not work. The crew was absolutely lovely, and the food was excellent.

I appreciate how quickly and kindly the people at the gate at DCA accommodated several of us who wanted to switch from the 6pm flight to the 5pm flight at the last minute. The flight crew was helpful to us too (dealing with luggage).

Very uncomfortable and cramped seats. Everything else was okay, the crew members were nice but nothing was exceptional.

Check in went smoothly. Flight attendant who was assigned my area barely paid any attention to me! She acted as though she was extremely busy and flustered. Maybe she was new?! I told her to change the language on my screen, she said she’d come back to help me but never did so I was able to solve the problem on my own. She came back and said she’d made adjustments on her end. Highly doubt it because I found the setting to change the language! Also, I noticed everyone was eating before we landed so I pushed my help button and she never came so I got up to find her to ask her if I can have breakfast. She said they are not serving breakfast but I can have a sandwich. Yes, that was her response as I saw everyone eating breakfast!!!

It was great. The staff is always helpful and polite. The app is great and makes the whole trip and process so easy. They even offer a step to step guide to your correct terminal. And they keep all the information you'll need updated. Anything you can think of! Great experience.

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.

Short flight, but no drink/snack service. The flights both going and coming were delayed.

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 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.

awful delay, awful communication, zero updates throughout the experience of a giant delay

Our flight was delayed to Louisville. What made this worse was they did not have another flight attendant to service the flight. This caused an even longer delay. Then when a flight attendant did show up, she chose to "swap" flights with another flight attendant. Therefore, we had to wait longer for the other flight attendant to come to our flight. This is information that the gate attendant should not have shared. Processes and execution at American are broken. Passengers are feeling it. Fixing this starts at the top of the organization.

The gate got changed several times and the flight was delayed over an hour. Awful experience

It was an older plane. First Class was not especially roomy or comfortable. It was a short flight so there were no meal but they did offer mixed nuts which used to be normal but now is rare. Crew member was very polite and professional.

No Snacks or Entertainment. The flight was short, snacks should still be given.

The boarding process needs to be fixed. The zone don't work, especially when there is hardly anyone in zones 3, 4,and 5, leaving the majority of the passengers backed up in the aisle, especially because passengers seated near the front are blocking passengers who are seated in the rear of the plane. It would also help if the size of carry on bags was more strictly enforced.

My Internet did not work for Outlook email or basically anything. I paid for one hour of in-flight usage and it was terrible. I spent a lot of time on different sites and browsers with no luck and a lot of frustration. Other than that, the flight was on time, crew was nice, service was fine. Seat was OK even though I paid for the extra 6 inches. I cannot imagine how tight the seats in the back must be.

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.

Everything was fine. Flight boarded and departed on time. Seating was spacious enough for my carryon to fit under the seat in front of me. No complaints at all. Flight even arrived early.

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.
