My flight was delayed and I got back around 3.5 hours later than expected. I had to get a new connecting flight

Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.

The Atlanta airport had thunderstorms, which caused our flight to be delayed by multiple hours. Once we were able to board.the gate agent was rude and was trying to rush us onto the plane because the team in the plane was about to run out of hours once we were all aboard the plane they ran into an issue where the catering truck was filling up the back of the plane and they left and had to come back because they didn’t fill it up all the way, causing even more of a delay. My seat was very tight. I didn’t have a lot of legroom overall this was a miserable experience.

No Internet, no backseat screen, no nothing. I bought a Delta ticket and ended up on American Airlines. How did that happen?

Connection flights should be spaced out farther because too close I missed my connection.

The flight was way too HOT! And the plane did not have any in-flight TV entertainment.

The gate attendants and the crew were terrible. Because of high winds, they needed to carry more fuel, so they had to get volunteers to take the next flight at 6 am the next day. They did a terrible job of it - our flight ended up taking off just under 3 hours of the scheduled time. I hope to never fly Delta again.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

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.

My flight consistently said it was on time and the plane didn’t arrive until after 30 minutes after take off and nothing was announced to passengers
