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.

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!

One of the best crews and best flights I’ve ever had! Really great experience

The bus ride from the terminal to board the plane is uncomfortable and stressful when making a connection.

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!!!

United staff were very communicative, the new starlink Wifi is amazing as I was able to work easily.

Starlink internet made the flight time shrink and I was able to work.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

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.

Please please take consideration when setting cabin temperature. The vents were not functional and it was over 70 degrees in the cabin during the winter months when most people are used to much cooler indoor temperatures. I was down to my white t-shirt and the sweat pants I wore from Auckland to San Francisco and was sweating profusely and there was NO VENT!

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.
