Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

6 hour delay including one after we were boarded. Horrible experience.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

Nothing unusual. It was fine. I hate having to pay extra for my seat.

Everything was Okay. I was disappointed our luggage didn’t arrive with us and came in a flight 7 hours later. Representative said the will be delivered to the hotel. They have not arrived 24 hours later

We splurged and decided to fly first class. Seats were roomy. But flight crew arrived late to the airport. That delayed our flight. Most of the passengers had to try to make connections flights. I felt bad for them. We checked 4 bags. We got three from the baggage claim carousel. 4th one was lost. Delta online help wasn’t good. Baggage claim staff were sympathetic and nice but we waited around for almost 2 hours and it had t been found. They did find it several hours later and we had to drive back to airport to retrieve it. I won’t be splurging on 1st. Lass again anytime soon. I think we got worse service. I am also not a huge fan of delta but we have family in ATL so we don’t have a ton of choice. What should have been an easy flight turned into a stressful event due to flight crew tardiness and baggage mishandling.

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

The flight was so late that I had to change connecting flights, turning a five-hour trip into a fourteen-hour nightmare.

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

It was reported to the passengers that Delta failed to schedule the crew properly. This error caused the pilot to show up about 30 minutes late. All in all Delta's inability to take care of this basic function resulted in about an hour delay.

In this flight we had selected seating for our family in the middle of the plane in a 2x2 format. The airline changed them to the very back row of the plane and split them to 3x1. Why pay for seats that allow seat selection if the airline will just move them to the worst seats in the plane?

Never happened, because of the first delayed flight I lost the connection and had to wait overnight and take two flights to reach my destination.

The plane was delayed ~ 40 minutes. Communication could have been better. The entertainment was poor. We were not offered headsets by the flight attendants. The arm rest pad did not work properly, thus, I could not select what I wanted to watch.

A/C wasn't working. Made the 1.25 hour flight seem like 4 hours! Even at altitude it didn't cool down.

See my previous comments. I was probably booked in business but was moved to economy

No water on the toilets, dirty sits. 4 hours delayed departure.

East Lounge in Denver was terrible. Turning away active military on orders? Really? Sad.

The flight was delayed, but other than that everything was fine.

Two hour flight delay, it was awful and loss of sleep.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.
