Pros: "Good access to charging, good food"
Cons: "More space:)"

Cons: "No room to move, too hot, no sound when trying to watch movies."

Cons: "We experienced a one hour ground delay at Sea-Tac which was unrelated to our airline. The pilot kept the passengers informed with timely updates, and we finally departed about when the pilot predicted we'd get away."

Cons: "Compared to Virhin Australia crew, Delta staff seem almost poorly trained in comparison. For example, Drlta crew don’t check your pass, don’t immediately move down the aisle to move along tourists busy discussing their seats and then line up for Boarding seems chaotic at best."

Cons: "Old cramped untidy and limited drink service"

Pros: "Nothing"
Cons: "Multilpe delays"

Pros: "This was our first time flying Delta and it was a very pleasurable experience. Boarding was very straight forward and the seats allocated comfortable. A surprise for us was being asked if we would like to move seats from the back of the aircraft to Comfort Economy (we think it was to do with weight balance! but appreciated very much none the less). The flight attendants were very professional and helpful, as you would hope all attendants on all airlines would be. We'd gladly fly Delta again anytime."

Pros: "Great"
Cons: "Too many announcements"

Pros: "Alaska Airlines is way overpriced and way less comfortable than Delta. I’m a Delta loyalist forever now!"

Pros: "Nothing"
Cons: "The fact they wasted two days of my trip with my son travelling from the U.S. to China because they didn't know about transit visa regulations. And so far they offered a 75 dollar voucher for participating merchants. Unacceptable"

Pros: "Enjoyed food and movies.Woul"
Cons: "Would like more comedy or romance movies. Becky"

Cons: "We disliked that our baggage was lost and we do not have it two days later."

Pros: "Nothing. Delta sucks!"
Cons: "Poor management prior boarding"

Cons: "Enforce your baggage size and number limits. A significant number of passengers take bags onboard that are oversized."

Pros: "Lufthansa is a great airline."
Cons: "Food was so hot that it was difficult to remove the packaging to be able to eat the pasta.... Desert was ok, brownie was real hard and too sweet...."

Pros: "Salmon dinner was the best dish Lufthansa ever served"
Cons: "Flight attendants disappeared after serving dinner. They didn't come around once between dinner and breakfast. This was the worst LH crew ever."

Pros: "Staff was extremely nice and helpful"

Cons: "Check-in Seattle was ill organized and folks cut and groused"

Pros: "Just about brand new Airbus airplane, very nice! Everything worked, seats reasonably comfortable for a long flight. Boarding worked well by area of the plane, friendly crew."

Cons: "Food could be better"

Pros: "My seat was next to bathrooms when everyone start using it start smelling too much very uncomfortable sitting there. Food chicken was very salted, they run out of drinks 10 hours flight dinner served at begging no snacks or anything till 2 hours before landing"
Cons: "At least air fresheners in bathrooms or something better so passengers can sit comfortably"

Cons: "The flight itself was good. But the connection wasn't. For this schedule, it is next to impossible to make the connection. The gate that the SEA to FRA flighy arrives at is at least half an hour away from the gate that SEA to MAA leaves from and there is a security checkpoint in between."

Pros: "The flight attendants were friendly. The seats were new. The movie selection was good."
Cons: "The scrambled eggs for breakfast appeared to be powered eggs, or overcooked eggs. The storage bins for the luggage were very small for the middle seats (aircraft was an Airbus A330-200). After several hours of flying, there was trash in the aisles and on the toilet floor. The toilets were dirty and not cleaned. Finally, the toilets ran out of paper towels and tissues with 3 hours to go in the flight, and they were never refilled. The flight attendants put a roll of toilet paper next the sink to use for your hands."

Pros: "Lufrhansa is a fantastic airline"
Cons: "The seat pitch and width were too small."

Pros: "One of the flight attendants was awesome!"
Cons: "I got bit by bugs. I’ve never experienced something like that on a flight."

Pros: "Movie choices were great! The crew was very nice and accommodating."
Cons: "Uncomfortable seats, but that's a problem with every airline."

Cons: "Very bad food"

Cons: "Seats are tiny and crews English was just okay."

Pros: "Very friendly crew"

Cons: "Rating and bad customer experience shared on web...."

Pros: "The selection of in-flight movies is excellent. That has been my only positive experience"
Cons: "Lufthansa is always late, every single flight I have caught with them has been at least 45 minutes late. Additionally they are very inflexible if you want to make a change to your tickets after purchasing. Boarding the plane is handled very inefficiently and takes much longer than most other airlines. The food is mediocre and the drink cart only comes by every 2 hours or so which is far too infrequent"

Pros: "On time Boarding was convenient"
Cons: "Food Seats"

Pros: "Crew is very friendly, seats are extremely comfortable and good room overall, comfortable flight."
Cons: "Hi, To be honest, it was embarrassing to serve that dish on such a major airline. Chicken with bbq sauce and corn or something like that. Was distasteful I couldn’t take more than 2 small bites."

Pros: "The Entertainment, the Food and the nice and friendly manner of all personell."
Cons: "Nothing."

Pros: "That was the most comfortable flight I have ever had. Famous German standards of excellence. Everything was just as it's supposed to be. Punctuality, politeness, order - just perfection. Thank you for such a great treatment!"
Cons: "N/a"

Cons: "Crew was not nice at all. They would skip us along the way while serving others, or even drop ice on us, and never said sorry once (instead, they would say it's only ice, or if I want 2 since they skipped me already twice when serving tea unlike the passengers around me on both sides). We paid nearly $6k for the 3 of us, but the crew made us feel as if we paid nothing. The entertainment system did not work well, and most of the time the movies refused to play. We were always suggested to restart, and were not even given free access to internet as an alternative. No one ever apologized for anything in the entire flight, it felt like this flight was a favor."

Pros: "None"
Cons: "Most of it"

Pros: "Everything was generally good and normal"
Cons: "Except the plane was roasting and had no vents"

Pros: "it was quite comfortable"
Cons: "luggage got delayed by 2 days. No dresses to even wear. Plus lufthanse didn't know where my bags were."

Cons: "Leg room was less"

Pros: "Aircraft crew was decent."
Cons: "Seattle to Frankfurt aircraft was the dingiest and most crammed aircraft I have ever used on an international leg. The seats were tiny so much so that some other passengers were not able to fit in! The lighting was gloomy, restroom dirty within the first hour of the flight, no space to keep any magazine or books on the back rest of the seat in front of you, etc. Overall - such a bad experience. Not expected from Lufthansa, especially as I have had great experience with Lufthansa earlier."

Pros: "The view - flying low over the northern extremes of Canada was superb. Thanks to the pilots etc."
Cons: "The flight was late arriving at Frankfurt. I requested a notification to my connecting flight. Crew member frowned, turned away and in formed me, "We don't do that". I ran to the Connecting Lufthansa flight and barely made it on time."

Pros: "The boarding process made it easy to find my seat and get settled in."
Cons: "My seat back didn’t recline. But the one in front of me did. So I was penned in."

Pros: "The staff and food was great!"
Cons: "Seats are very close. Not comfortable when neighbors are big and fake up my space!"

Pros: "Our dinner meal was quite good for airline food. After they reset my TV three times, it worked good."
Cons: "The breakfast left a lot to be desired. Leg room was very limited, especially after the person in front of me reclined their seat."

Pros: "service, good quick flight"
Cons: "late departure in Frankfurt; high noise level of the Embraer plane;s engines; failing AC in the cabin"

Pros: "Liked the crew, the food, blanket and pillow."
Cons: "Frankfurt airport wheelchair service needs to be better administrated."

Pros: "The crew were very helpful and polite. The seats had plenty legroom. The food was excellent, and entertainment was also very good. Most importantly, there was no delay."

Pros: "OK"

Pros: "Food was pretty good except for breakfast. Hospitality is great. Wish there was more access to water."
Cons: "Big passengers sitting near smaller passengers is annoying as they encroach on the limited space that exist and armrests suck as per usual."

Pros: "Our attendents were clearly focused on our needs. Efficient and still very human and kind. A real treat."

Pros: "Big airplane and therefore no turbulence. Food was good for airplane food. Boarding was pretty fast considering the number of people. Didn't have problems finding overhead luggage space"
Cons: "Sat next to the bathroom and therefore repeatedly got bumped by people and carts as they passed. The stewardess was polite but had an obvious fake smile pasted on her face. A bit more honest facial expression would have been more comfortable."

Pros: "Everything! Excellent stewards too!"

Cons: "You lost my luggage"

Pros: "Price"
Cons: "Few choice of movies"

Pros: "The variety and ease of use of the entertainment"
Cons: "The boarding was not at all well organized. There were no instructions about what to have ready and the woman who checked our passports was rude."

Cons: "I really felt the food was not as good as I had on other lines. To help I had the chicken - and the veggies with it were mush as was the spinach with the egg dish - which also did not have much flavor"

Pros: "Thank you for the great experience!"

Pros: "Entertainment options were incredible; great legroom in our seats."

Pros: "Food and beverage service was excellent."
Cons: "Cabin temperature was way too hot. Leg room was too small"

Cons: "A kid next to me keep shifting and kick me and nudge me all the time. His dad was trying to stop him from moving too much but couldn't control entirely. I kept waking up"

Cons: "I was denied boarding. No one told me that my passport had to be 6 mo. to expiration. Why the hell do you even put an expiration date if you're going to deny all travels prior to 6 months?"

Cons: "Food was not satisfactory compare to other airlines like BA Everything was excelent."
