Pros: "Avoid Alaska."
Cons: "Alaska Airlines flight was late and made me miss my next Alaska Airlines stopover flight. They could have gotten me off the plane sooner so I could make the next flight, offered me compensation, or held the flight that was still sitting in the terminal. Instead I got a flight to another city two hours away and had to rent a car to make it to my destination."
Pros: "Window seat"
Cons: "Cramped. Chaotic late boarding. No food. No entertainment. High price."

Pros: "Excellent service in most every respect! Boarding was easy, accommodations were quite ample, food was great, and the entertainment was plentiful."
Cons: "Slight problem with making my seat into a bed, which wasn't fixable. Movies were good, except for the trailers before and after each, which seemed to take forever! Didn't get the seats my wife and originally booked with China Southern/Delta, but the substitution was quite adequate! Problems with checking in on flights, as neither airline seemed to be able to deal with this split ticket! But they tried very hard to make thing up to us, which goes a long way to making us feel like we are valued customers!"

Cons: "I missed my outbound flight from Chicago to Dallas, and although I called to inform Delta, my return trip was cancelled and i did not find out until the day of my return to Chicago. When I called Delta to figure out what was going on, I was put on hold for two and a half hours. I'm not giving the flight a bad review, since I never got on the plane, but I'm disappointed with the accuracy and care for customers that I've experienced with Delta service. Delta was the first company I've ever flown with when I first started travelling when I was twelve years old, and it is unfortunate that I will probably never book with Delta again."
Pros: "I've done many flights this distance, and just take for granted that there will be entertainment. There wasn't."
Pros: "Unfortunately there were unavoidable delays due to weather but the staff gave regular updates and were very honest. Also, they brought out food and drinks for people bc they knew people wouldn't feel comfortable leaving the gate in case of changes. Staff handled the whole situation very well."
Pros: "Seatt space was great."
Cons: "The seats didn't recline at all making it nearly impossible to sleep."

Pros: "Quick non-stop destination flight booked a day before for very cheap. Wonderful."
Cons: "Nothing."
Pros: "Boarding was fast. Takeoff was not bad given weather conditions. Landing was super smooth."
Pros: "It was smooth and uneventful. At 6 AM that is saying a lot...!"
Cons: "n/a"
Pros: "Flight crew was nice enough, but the intercom woman was very annoying; spoke like we were children. How many times do you need to announce a last bathroom call? 1 is diffident. 5 is excessive."
Cons: "Charge you for EVERYTHING. Seats were so small i couldn’t bend down to find my headphones in my bag on the ground. I’m 5’4” 115 lbs. no in flight WiFi or entertainment. It was a long flight."
