Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .
Flight was too crowded and seats are too small, especially since passengrs are getting larger. Having a middle seat is ALWAYS tough! Woman on my left was large & kept creeping in to my space. Flight personnel were great! Have more savory rather than sweet snacks please.
My issue was with TSA agents for delta airlines. My luggage got flagged. The agent was going thru another persons first. He took 20 min to go thru hers. I asked them to bring mine closer so I could sit down . They said you can go sit it will be fine. I said I am supposed to keep my eyes on my bags at all times. The agent was meticulously unwrapping 2 gifts that the lady had and then tried to re warp it. He was trying to be kind i get it but 20 min for me to stand watching him do that was ridiculous. It was 6 am and there were a ton of travelers. Mine was flagged for some air packed tea that I bought in Turkey. My previous delta flight and 2 others before didn’t flag it. Consistency would be nice. Also on the flight the window shades were down for take off and landing - I thought that was very odd I thought they had to remain open for take off and landing.
The crew took good care of us. The flight from ATL to SFO is a longer one, and there were multiple beverage offerings. I like the 757's that Delta uses. Good airplane that is comfortable. I do wish Delta would separate Priority boarding from the better seats. I would gladly take a smaller seat in an open row than be jammed into Comfort just to get priority boarding, just to make sure I don't have to check a bag.
Gate agent rushed to fill hot jetway with crowd so it took over 12 minutes to go from gate to plane. Just like a discount airline Pooly prepared cabin and third time that claim of rough air prevented any cabin service. Friends on a Southwest flight at similar time had service.
I was uncomfortably cold on the plane. Other than that it was uneventful and therefore as enjoyable as a plane ride can be.
Only issue was with seating. The economy fare we purchased did say there was no guarantee the three people in our party would be seated together, and we were not. At the gate, the agent told us more specifically, the fare we purchased meant we would be seated in middle seats only. This should just be made more obvious.
Food was surprisingly good but the WiFi was not great
this crew didn't care much. bumping carts into seats more times than i care to remember
The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.
Very pleasant flight attendants. Gate crew rather loud chatting with each other.
Four plus hour flight delay in New York caused us to take off after 11:30pm. We didn’t arrive at our hotel until five hours after check in. Started the trip off feeling exhausted.
Plane was in bad shape. TV’s and WiFi didn’t work. Plane need a refresh. Not enough room for bags.
Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.
I don’t usually fly budget airlines or airlines in the United States. It was as good as any other airline. The seats are comfortable and the airline attendants are not rude & surly. Very nice flight (s).
They have the most inexperienced / rude flight staff I’ve encountered
very difficult boarding process - aggressive passengers not the friendliest crew
WiFi was not eorkig (again) And the plane was from 1990 with the screens which were.not touch and most didn’t even work and if lucky could tune in tv
I paid extra for a seat closer to the front. The TV didn’t work at all for the entire flight. Would have been nice to know before I purchased an “upgraded “ seat
