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"

Pros: "Not much."
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."

Pros: "We purchased seats with extra legroom. They were well worth the extra cost as we were very comfortable."

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: "Again 2 hours delay"

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: "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."

Cons: "Online check-in process. Boarding pass not available to be added to wallet. Unable to view; had to have the boarding pass emailed to me. No option to set up SMS tracking foe flight status."

Pros: "I liked nothing, and am sorry for the time i waist it with Alitalia. Especially after not letting me use the lounge even thought I am an elite plus with skyteam and Alitalia is one of the alliance member."
Cons: "Applying the rules and respect my skyteam elite plus membership."

Cons: "Strike delay. Very poor food. Cramped chairs. I flight entertainment"

Cons: "El avión, en especial los baños, muy mal estado La tripulación con poco tacto para atender La comida en primera muy poco apetitosa"

Cons: "Seat assignments sucked. Could not seat together"

Pros: "Flight was smooth"

Cons: "OK flight, evening Business class"

Pros: "Everything"

Cons: "As so often with Alitalia the flight was delayed by 1 hr 20 mins"

Pros: "Easy check in and easy baggage claim"
Cons: "They can easily work on the food"

Pros: "Flight was smooth and didn't feel like 9 hours! Crew handled an ill passenger in a caring and professional manner."
Cons: "Seated in the middle of four center seats, crew overlooked offering beverages/food a couple of times."

Cons: "This flight had the least legroom of any flight I've ever taken."

Pros: "Peu de place pour les jambes Équipage très sympa"
Cons: "Plus de place pour les jambes mais vol rapide donc Ok"

Pros: "the flight was on time"
Cons: "for sure the seats, the screens and bathrooms. the plane was so old!"

Pros: "The crew was really extremely courteous - and because it's off season, there was a lot of spare space."
Cons: "The only less than perfect score was food, but the circumstances mitigate that less than stellar note. The warm meal and snack were better than your average over-sweet snack you get sometimes coming from Europe... We had a delay that may have impacted the food (if you keep warm food too long...)"

Cons: "The plane was delayed 1 hour waiting for a crew member to show up. This caused me to miss my flight to the US at DeGaulle"

Pros: "We traveled the same way back but with Air France instead, which was a joy. This aircraft was uncomfortable"

Pros: "good onboard service"
Cons: "the business class wasnt really so good to my expectation."

Pros: "todo estuvo muy bien!!!"
Cons: "el desayuno o como quieran llamarlo es muy pobre"

Pros: "Nice opera music available while trying to figure out the antiquated entertainment system."
Cons: "Seating was the most cramped I have ever experienced. Service was relatively efficient and competent but not especially friendly. Really old entertainment system not easy to figure out. Lack of individual air control."

Pros: "Crew was pleasant there were many seats vacant"
Cons: "Flight boarding starte 25 minuets late"

Cons: "the food is terrible. he literally dropped my bread and picked it back up to give to me. it was soggy, tasteless and disgusting even more given the rude crew. I never comment a review unless it was a good or extremely terrible experience. One of the crew members was extremely rude to Americans. God forbid we ask him a question he would keep walking. For the price I paid and the duration of my flight (12 hours from LAX-FCO) I wish I chose a different airline. that was the most uncomfortable flight I've had in a long time and I travel often."

Cons: "Change of gate at BCN with no notification"

Pros: "The flight itself from NYC was great, the connection flight was great."
Cons: "The worst boarding process I ever seen! The airport people and crew didn’t tell people what’s going on, there was a uhh delay. Big lines of people just standing and waiting. The flight took off 45 min late!!"

Cons: "Because the flight was one hour and a half late"

Pros: "The fact that I had more legroom than I expected was surprising."
Cons: "The staff were super rude, forgot my food TWICE. Boarding took ages, and once inside the plane, they took a long time to get on the runway. Food was terrible, the bread was hard as rock. IFE has some relatively new films, but the screen is very small. The screen has terrible quality, and honestly makes the flight excruciatingly boring if you don’t have other sources of entertainment."

Pros: "The flight attendants were very nice. Great service."
Cons: "They left us inside the plane for more than 30 minutes waiting to depart. Then when we were close to FRA they tell us they cannot areive because of the weather and got more delayed. When we finally get to FRA, there’s no machinery to get us out of the plane because it was broken. We had to wait for them to find some stairs and then take a shuttle while raining to the airport inside."

Pros: "legroom, service, boarding, meals"

Pros: "Nothing"
Cons: "Seats too cramped and close to facing seats."

Pros: "Confortable space, great food taste,"
Cons: "When we asked for the late food service, they told us they did not have any more left. We ask them to look for anything left and after hour the food still not arrived."

Pros: "Efficient!"

Pros: "Nothing"
Cons: "Legroom inside the aircraft is too small. Salted and sweet snack options including cookies. This is on a two hour flight. Very uncomfortable journey"

Cons: "Lost our luggage from Rome to Malta. Now, 13 hours after arrival in Malta, no one can tell us where our luggage is!!"

Pros: "In flight entertainment was good. Lots of choices. Plane was clean. Staff was friendly."
Cons: "We had only an hour for our connection. Ordinarily, this is enough time. However we had to go through passport control during the connection and we almost missed our flight. When traveling internationally, this should be considered. Rome airport (FCO) could do a better job of managing passengers with quick connections. It was a mess."

Pros: "Entertainment options"
Cons: "Had problem with luggage, did not like food specifically cheese on dark bread sandwich, did not like going to gate but would need to climb stairs and get shuttle to plane"

Pros: "I didn't"
Cons: "The flight was only supposed to take two hours but instead they sat around for another hour and a half or so and then there was so little leg room that my knees even if I was all the way against the back wall showed into the seat in front of me so bad that I had to stick them out in the aisle and said crooked and then my seat would not latch"

Cons: "I.m 6'2 and it was impossibly uncomfortable"

Pros: "Nothing"
Cons: "Food quality was awful, no entertainment whatsoever and the smallest seats I have sat on. Legroom is extremely tight"

Pros: "Staff was friendly."
Cons: "The flight attendant at the check in said our luggage was too big and needed to be checked. We got a ticket from her but when we got to the plane nobody said anything and we simply did what we had done all the previous flights we have ever taken, we stowed them in the overhead bins. The flight wasn't full and in fact some overhead bins were completely empty, but I guess she had her job to do and thought it wouldn't fit, but maybe she could have asked if we had used it before. I don't know why they say it's too big when we had been traveling throughout Europe for almost a month and had taken it on 4-5 flights and many other trips. It all worked out. Footnote Air France never made a issue of the exact same baggage that Alitalia said was to big. The bags fit fine on all airlines we have traveled. The flight was delayed 45 minutes which made my connection a bit tight. I was connecting to Air France which is part of The SkyTeam alliance comprises with Alitalia but my luggage could not be moved to the Flight to LAX so I had to get the bag I did check and go through the process all over again."

Pros: "Nothing"
Cons: "You lost my luggage!!!!!! Now I'm standing in a long line with other lost luggage people. Düsseldorf is not a large airport and there was ample connection time. Not the way I wanted to start my vacation. Instead of driving south now I'll be waiting at the airport all day On the flight the seat in front of me folded back all the way to my head! How does that happen?"

Pros: "The flight departed on time and arrived 35 minutes early. The flight crew was very helpful onboard."
Cons: "Tried to upgrade my elderly parents to more comfortable seats when checking in, but was told the flight was full and there were none available. It didn't appear that way after being boarded and seated."

Cons: "We had booked a weekend getaway, first the returned flight was cancelled and changed for a later one that didn't work for us (we couldn't get to work on time), we managed to change that for another flight the day before, shortening our vacation, then, when we got to the airport, an hour before boarding, we find out there, without warning, that the outgoing flight had been cancelled! This time it wasn't automatically changed, and there was no warning, the only solution they were giving us was an afternoon flight the other day, shortening our weekend getaway even more. After half an hour of discussion, they found and earlier flight, with connection, double the time, but that would get us there at around 2pm, so still we were missing almost half a day, but that was the best they could do. The flight was OK, boarding was late, but hey, that seems to always be the experience with this type of flights. I would just say they are not very reliable, having both your outbound and inbound flights cancelled, seems to much, specially if you're just going for a short getaway, you may end up having a one-day getaway!"

Pros: "fast boarding"
Cons: "crews are extremely rude; whenever they had to move the cart in the isles they always ended up slamming every passengers arm without a single apology. and they have no control of the environment due to some young passengers were making loud noises during the whole flight."

Cons: "I tried to talk with the service desk to change my flight before the flight and the service team could not help me out because only the service desk outside security could look up other fights. I find this hard to believe and a little ridiculous that AirItalia would make their customers run around inside and outside security to switch flights. We live in a day of technology and have computers for a reason. There shouldn't be an issue why other flights can be looked up from only one computer. In addition, we boarded the plane and then we waited on the tarmac for 2 hours waiting to leave. The air was turned off and it was hot and stuffy inside the plane."

Pros: "Crew was nice and seat comfy"
Cons: "They should upgrade their intartainment system"

Cons: "No room and very uncomfortable"

Cons: "f"

Pros: "80 euro return from MLA to Rome, including bags. A snack & drink provided. Beat ryanair hands down!"

Pros: "Price"
Cons: "Paid for upgrade comfort seats. Did not get them on the outbound flight ROM-TLV. They could not explain why we did get the seats and have not paid back the 80€ for the 2 seats. Had to fight for the comfort seats TLV-ROM. DO NOT LIKE ALITALIA!"

Cons: "Individual in airport had us wait in line ONE HOUR TO GET CHECKED IN; he should be fired ; flight was fine"
