Cons: "Fix it"

Cons: "Kayak a howed my gate as something that didn’t exist at the terminal. I went to a kayak help desk to have a ticket printed that showed my TSA precheck because it wasn’t showing on my mobile ticket, and no one was there to help. I waisted for 10 mins. It then took me nearly 2 hours to get through security. I asked if I could get through quicker and was told I could not, despite it being passed my boarding time. I then ran to my gate where I waited for another 10 mins (no one was there, again) and then an employee came out and said they couldn’t let anyone board once the door was shut. He then directed me to the delta help desk (there was at least 20 people behind me who missed their flight). I then had to pay an additional $75 to get a later flight. The whole experience was awful and I’m disappointed with Kayak and the gate confusion, but mostly Delta and the lack of customer service."

Pros: "That it got me home"

Cons: "Sat on the runway for over an hour to get the gate. Unacceptable."

Pros: "Everything went smoothly - very happy"

Pros: "On time"
Cons: "Take a long time to taxi to the gate & getting off the plane."

Pros: "Nothing"
Cons: "Multilpe delays"

Cons: "Boarding was awful. It took about an hour to board and no reason was given until we were taxiing. (The crew was delayed.) Overhead storage was insufficient. Seats are too narrow. I paid for extra leg room, which I got, but I don't appreciate elbows in my ribs for the whole flight."

Cons: "late leaving, arriving and taxing."

Cons: "90 minute delay leaving LAX. Stuck on plane. 30 minuet delay getting to gate after landing at SFO. Stuck on plane again."

Pros: "Food was plenty."
Cons: "Long security lines at Logan. No free WiFi"

Pros: "Crew was wonderful, fine flight, very prompt"
Cons: "Was unable to board an earlier flight without paying $75. If there are seats it shouldn't be so difficult to be moved."

Pros: "Was tired and the FA helped me find a row that I could stretch out on and relax. After a long trip from Moscow, the FA's volunteering to help and accommodate a beleaguered traveler was most appreciated!"
