8.0 Very good
The WiFi on the plane was out. I also thought movie options were lacking.
C
2.0 Poor
They changed my seat assignment from window to middle. I have a physical need to sit by the window because of spinal issues. I unboarded in pain, I also was placed between 2 very large men. I am very disappointed and now dealing with the physical aftermath.
M
4.0 Mediocre
These Delta 717 jets are ancient. No entertainment and you have to pay for WiFi that barely works and goes in and out the whole flight. Delta should be ashamed flying this garbage.
S
2.0 Poor
The crew were awesome and ready to help as much as possible. The gate agent in Atlanta was tremendously helpful. The delays were ridiculous. Getting home at 4am when I could have driven home faster was unimpressive. Being delayed for countless hours through the night wasn't a great travel experience.
S
2.0 Poor
The staff and crew were wonderful. The delays were atrocious. The missed connections problematic. Getting home at 4am and having to go to work at 8 am, not a great situation. The gate agent in Huntsville was amazing. She helped everyone efficiently and with excellent problem solving skills. Her communication was helpful, timely, and thoughtful.
