Pros: "Q-suits. Very comfortable and private. Great upgrade to the 777. WiFi now available for very reasonable price"
Cons: "Bus transfer to Termial 5 is VERY poorly organized and takes over an hour. This makes it harder to get to Terminal 5 even if you don't have to clear security again. Seats had a bar under the padding at about the position of my hips. Uncomfortable to sleep for several hours"
Pros: "crew is very professional"
Cons: "this plane is really old and junky. other flight times on this route get a much better plane"

Cons: "Don't push a credit cards on us via in person brochures. I found it very unsavory."
Pros: "People were friendly. Flight was comfortable."
Cons: "Staff incorrectly assessed documents needed for visas, and told us we were incomplete and needed to return home. Instead of looking up policy, we were denied boarding mid-flight, missed a wedding, and had to spend three days in London instead of our destination. Also, we got bug bites during the flight that turned out to be from bed bugs, which followed us home and caused much frustration for months."
Pros: "Comfortable seating, pleasant food and entertainment."
Cons: "Not being charged $1200 for a ticket that I already bought, but had been voided with no notice. And Virgin Atlantic staff not friendly or helpful in any way with this situation."
Pros: "This is the way to fly long haul."

Cons: "Seats are not the most comfortable and sometimes the screen on the entertainment tv doesn't work that easily."
Pros: "Speedy boarding and good locker space"
Cons: "Lack of room in seat especially with seat in front reclined."
Cons: "Overall, I am disappointed in Kayak for listing my round trip flight as KLM, when in actuality, only one short connection of this flight was actually KLM. My itinerary said KLM all over it, but in the fine print it said "operated by Delta." This is dishonest and misleading."
Pros: "There was one stewardess that really made the trip feel less "restricted" in the way she would greet, talk, serve, and just being what I always experienced good international flight staff to be. I wish I was able to get her name so I can praise the airlines for hiring such a great staff like her."

Everything was great but the difference in paying for comfort + did not seem worth it.

Pros: "Nothing. I’ll never do business with Delta again. Not even to make use of the $80.00 voucher credit they extended. Delta San Antonio manager Delphine is an awful representative of customer service, and a horrible person!"
Cons: "I should have never flown Delta."
Pros: "Crew great....moved passengers around near us for Covid related separation."
Cons: "Cramped.....too many seats in too small of a plane....I'm 6ft / 190 lbs"
Cons: "Seats were a little dirty especially for the COVID-19 going around."
Pros: "The boarding was fast quick and the staff was very friendly."
Cons: "The bathrooms were very dirty and there was not enough food and drink supplies."
Cons: "I dont know WHY Delta changed my flight with ALIITALIA, but, DON'T DO IT DELTA. The check in process took an hour, not talking about the line, the ACTUAL checkin at the counter. I couldn't complete my web checkin at the AliItalia web site. Landed in JFK, still sucks as an airport, nobody helps, nobody explains anything, very poor signs and instructions, Global Entry kiosk are hard to spot. My connection ticket didn't have the TSA/PRECHECK legend, went to AliItalia counter, the lady at AliItalia barely said anything when I asked for help with that, her immediate answer was to disengage and sent me to another terminal "to talk to Delta". She didn't explain or didn't want to give an explanation until I started to act as an already 9hr30min flight frustrated customer in a very old, very poor plane with poor food service. Again, I bought an over $1,000 ticket with DELTA, NOT ALIITALIA, if Delta send people with their "partners" at least make sure that they are taken care of properly."
Cons: "Assigning seats at check in? Why was that a thing? Also why did we have to wait for almost an hour once we landed to be given a gate for us to unload? So stupid the whole thing."
Pros: "Good variety and quality meals during the flight as well as a super array of entertainment"
Cons: "The seats lack cushion so a 7 hour flight gets quite painfully after a while"
Cons: "The boarding process was awful. The gate agent was extremely rude - was shocked she was representing Delta. There was police on board arresting two passengers and crew was not saying anything."
Cons: "They ran out of food by the time they got to the back of the plane."

this is a great airline to fly on. I have not ever had a bad experiance with China Air.

Cons: "Airport boarding lounge was ice cold. Staff couldn’t be bothered with it."
Cons: "I paid for a window seat through your website. When I arrived at the gate I saw that I had a middle seat. China airlines stated that they do not honor outside booking seat request. It was very uncomfortable for 16 hours."
Pros: "The seat @ premuim economy is excellent with great amenities. Food was awesome and catered to cutomers diet needs. The crew was great considering the Language barriers."
Cons: "Nothing! Awesome Airline. Would use again when traveling to Asia."
Cons: "Provide cover for eyes so that we can sleep better"
Pros: "It was a two and a half hour flight and even in economy they served a full lunch with drinks included and tea and coffee service after. And they were so efficient!"
Cons: "No complaints at all, it was a great flight experience."
Pros: "Amazing lady who worked at the counter. So fast and efficient. I’ve never seen such efficiency at any airline before. Thank you."
Pros: "Sitting in the emergency row."
Cons: "More veg. meal options. Please make sure to offer a complete balanced meal, not just a serving of veggies."
Pros: "Entertainment selection"
Cons: "Food and drink selections were ok only. They ran out of one option for dinner."
Pros: "Large screen, plenty toilets, good leg room, kind stewardess, great handicap assistants"
Cons: "Food can be better"
