Everything about this flight was good except for the very end when I reached my destination. Everyone from the tune to the wheelchair escorts were great with the case were great but I miss you with people at the check in this at the very end. I need help from the chicken desk because I forgot my pillow on the plane The female worker at the chicken desk said that they found my pillow and she was going to retrieve it for me. She left a 30 minutes without any update and her so she saw me walking back and forth waiting for her and they didn't even bother calling her or radioing her for any updates. They were busy because they were behind schedule and they were overwhelmed but thanks because at least glanced me and try to give me an update just a quick radio check or phone call. I don't care about the pillow but if you tell me to wait, I waited for at least half an hour before I said something and I just left because they wouldn't bother talking to me so I could, so everything's going in the review. I took pictures of the two men that were left working at the check-in counter. The totally ignored me despite the signals I've been giving them. I don't see any offers in the kayak review to add pictures or screenshots so I'm going to post another review I don't know their name but I'm pretty sure Delta will find other names when they see the review. Google with pictures. There was another guy at the chicken counter bring an orange workers vest who finally left after telling me that the girl that was retrieving my pillow is working the gates now. That would have been if they just told me that's what happened. But I had no update. Make me wait for nothing. Thank you Delta airlines!

Crew was real good, flight was smooth and came in early.

Should never have had to go to Detroit from Orlando back to Tennessee!

Free & relatively fast Wi-Fi. Would've liked a wider drink selection.

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

Everything went smoothly, although the usual gripes about airline travel were still present: the boarding process is inefficient, the snack selection is limited, and so on. Since there was extra space on the flight, the gate agent rearranged many people's seats to put people on the aisles and windows, leaving the middle seats empty, as much as possible, which was pretty great.

Miserable. This entire round trip was miserable. I booked evening flights to and from Detroit on consecutive days that should have had me at my destination by 10:30. Instead I arrived after 3am on my flight to Detroit and after midnight on my return. Multiple unforced errors like awaiting bags to get put on the plane for almost an hour in Detroit and a 20 minute delay to pull up to the gate in Atlanta has me rethinking my assumption that delta is the best and most reliable airline

2+hrs delay without any reason provided and a cramped flight

Flight was delayed and no reasons provided. After the passengers were boarded, the crew made announcement that the captain has jot arrived and he would take another 15 mins. All passengers patiently sat until the captain came and started. Terrible experience!

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!!
