Cons: "Space on airplanes"

Cons: "The cabin temperature was very hot"

Cons: "A/C was not working well, cabin was too warm and stuffy. Long delay on take off. Can not hear and understand pilot through PA system."

Cons: "The Anchorage airport was FREEZING cold and it was August, maybe a little less AC IS IN ORDER"

Cons: "Food"

Cons: "Food is always bad."

Cons: "Cheerless stewards could perk up."

Cons: "No AC for an hour before takeoff - very uncomfortable. Audio for tv did not work."

Cons: "Hour late and no wifi!"

Pros: "New plane with good features. I was very comfortable."

Pros: "the plane was pretty empty"
Cons: "The times available were terrible!"

Cons: "Nothing"

Pros: "New plane, charging stations"

Cons: "It made no sense to board an hour and a half before takeoff."

Cons: "Change the movies more ofti"

Cons: "I feel like all the problems the aircraft had it should've been repaired before trying to use it, upon boarding they told us the left engine had to be started from an external source, as a new flyer that was terrifying to hear"

Pros: "the food was really top notch and service was great and friendly"

Cons: "The boarding process at LAX was awful. I’m sure the horrible shuttle wait and transfer from terminal to terminal is the airport’s fault, but the airline did not do anywhere near enough to inform passengers of what was in store. It was confusing and annoying."

Pros: "Easy and on time and Delta Comfort is always the best. Easy boarding process too!"

Pros: "Quick boarding process"
Cons: "Wifi stopped working halfway"

Cons: "Great"

Pros: "Everything was fine. Delta did a great job."
Cons: "The kid screaming in my ear for 3 hours"

Pros: "That we finally arrived."
Cons: "That we didn't arrive even remotely close to when we were supposed to."

Pros: "Total Experience of Flying on this Airline ."
Cons: "No Comment."

Cons: "Cramped seating for premium Econ"

Pros: "It’s was super smooth! Fast service and great customer service."
Cons: "The intercom was a little messed up."

Pros: "It was short and fast."

Pros: "Great movie selection"

Pros: "Delta did a really good job as always. Cheaper, more comfortable, and a WAY better experience than Alaska Airlines."
Cons: "Nothing."

Pros: "Not much . The boarding process took forever and the lines through TSA took longer .. no direction to lines and I was standing for 10 min before saying something to someone and they said o there’s another line."
Cons: "Almost everything besides the staff on the plane"

Pros: "Kara was really nice to us."
Cons: "Noisy plane."

Cons: "The plane bathroom was old and junky"

Pros: "Other than the delay by the Hong Kong Airport controller, everything went smoothly. The plane was late to Seattle."
Cons: "The luggage custom clearing would be much better if we could do it like the Vancouver BC where an electronic monitor was used to identify one's luggage without the need to handle them manually. Much more efficient and allowing folks to get on the connecting flights easier."

Pros: "Movies"
Cons: "Lack of legroom in economy"

Cons: "Food was bad."

Cons: "Poor WiFi. Paid extra to get it, but didnt sporadic at best."

Cons: "Nothing"

Cons: "horrible boarding management in SJC."

Pros: "Bags arrived on the belt quickly"
Cons: "Why is there not saying precheck to use after you've been funneled through customs? ATL is advanced enough to have kiosk for arrival, even for those confused and not with global entry, but then forces you to wait in security line instead of the typically faster tea precheck line. Every minute I'm in line, I'm not spending money"

Pros: "The landing experience."

Pros: "Service and flighr smooth"
