Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

I always fly Delta main cabin and pay to upgrade my seat to preferred/extra leg room. However this time even with the buying the upgraded seat I was extremely cramped with very little legroom and unable to move comfortably. For some reason meal service was very early in the flight and my row seemed to have been skipped. Most of my attendant calls were unanswered. I was unable to get extra water, or crackers/snacks to make up for my missed meal. I always carry protein bars in my personal bag, but with no extra legroom I wasn’t able to access from underseat in front of me. I am unable to sleep while flying so I read and count on in flight entertainment. However the passenger in front of me reclined their seat fully preventing me from being able to view the screen or be able to rest my book on tray table to read. One of the first times I’ve been completely disappointed in Delta. I fly internationally 2-3 times a year.

Flight was delayed due to weather. Crew did a nice job of making us comfortable. No complain complaints.

This was the second flight this week with flight attendant Marcus I’m not sure if his last name is Lane or Lang but this guy is awesome. He funny, attentive and his service is 5 stars. Marcus makes business travel more enjoyable !

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.

Luggage delayed and 6 days later I still don't have it.

In thirty years of traveling, mostly with Delta, this was the worst day ever.

I am so shocked at the service in first class. We were not greeted or offered a beverage for 45 minutes into the flight. She did however have time to write a long note. I just wanted a snack and something to drink. We were never offered coffee and the snacks came after dinner? It was the oddest flight I have ever been on. The gentleman next to me got up and gave our dinner box’s to the flight attendant and asked for a second glass of wine for each of us. Our dinner boxes sat on our tray for 20 minutes. She was rather distracted. He then asked another flight attendant for wine… finally we had a second glass. I was trying to give her some grace, she also told the man next me we couldn’t have any more wine because we drank it all… after landing the seasoned traveler next me ask for her employee number. Then it was a mutiny! She was refusing and it got tense. The captain came and asked what was happening, the flight attendants totally gave a biased account of the fact. The captain told the police the man I was seated next to was intoxicated! That was completely inaccurate and it really escalated things. I policeman found me at the luggage carousel to verify the facts. The flight attendants made false accusations that he touched them! That never happened. It was a very poorly trained crew. I am so anngry and shock by the entire experience! It was terrible service! I would like a refund for what I paid to be in first class and the most uncomfortable flight ever. I always fly Delta, it has been wonderful. I was so flustered by the entire experience! Please give me an update on this matter! Thank you, Kelle Myers

My seat was moved closer to the front of the cabin since I had requested wheelchair assistance to the gate.

I always appreciate when everything is on time! In this flight you have a short connection and it could be stressful , but is was easy and fast. They even ask people to wait so the ones that have a short connection could leave before. It was the fist time that something like this happened.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

My suitcase was destroyed. The top part where the handle is is completed broken. And unusable now.

Since when do I have to pay for my checked bag? I have a United Explorer mileage plus silver card and I was charged for my checked bags. This also is an international flight. So I would like an explanation to be clear before I choose an airline please?

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

I had a bad experience with the security at IAH and felt like a sardine on all 4 legs of my journey.

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

Oh my gosh, I loved my experience with United! they made me want to travel more often.

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.
