Airline reviews
Pros: "The whole business class experience"
Cons: "During the same trip I discovered 2 different arrangements of the Business Class cabin on Singapore Airlines A350, SQ469 CMB-SIN, and SQ036 SIN-LAX. On the SQ469, I occupied seat 12 A (mono, aisle-window): A lot of plastic curved walls etc. For larger persons, the result is not quit comfortable."

Pros: "Plane was super clean and comfortable. A long flight but we'll cared for by host."
Pros: "I liked that on the longest leg of my trip - I had an entire row to myself to stretch out. Im old, things like that are important...along with compression socks...haha!"
Cons: "I think the food - I dont know exactly what, because we're on a plane - but I think it could be a bit more appealing? More greens, colors? Not sure, but it was okay."
Cons: "Luggages did not arrive with the flight as it should be. It got lost in Sydney from Queenstown on flight SQ 6683 operated by Virgin Australia (VA 162)."
Pros: "Entertainment system ok"
Cons: "Change if gate 30 minutes before departure and no info at old gate. New gate very far away, terrible for old people."
Pros: "Handset to control screen didn’t work. Airline reimbursed me with $75 voucher for inflight duty-free shop."
Pros: "Prompt boarding, friendly service, decent food, plentiful entertainment. Singapore Airlines was a great choice for my flight from Texas to England."
Pros: "more room in the seats - excellent hostesses who are so friendly and helpful - lovely food."
Cons: "Please don’t use just fly.com ever. They cancelled my tkt and never accommodated a new one"
Pros: "Friendly crew I like that a lot. The diabetes food choice ecselent Thank you"
Cons: "The toilets were very dirty"
Pros: "The crew was amazing and helpful. The food was really good and the flight was timely if not early to my destination."
Pros: "The crew was polite and continuously offering drinks, headphones and food/snacks. Kept us comfortable and happy during the flight!"
Cons: "We arrived more than a half hour late, and considering this was about 4 am, this was significant. The guy in the middle seat was tall and had to speard his legs intruding on my space."
Pros: "The crew was terrific and friendly as I expected."
Cons: "I have no other suggestions here since I'm pleased with the flight and services."
Pros: "The crew"
Cons: "Boarding by rows and not like cows all at one time"
Cons: "Chose the option with Swiss because it showed that a checked bag was included. Got to the airport and was told to pay up for each checked bag. Great start to the trip."
Pros: "Crew was very attentive, information from the cockpit was enough to let us know but not disruptive"
Cons: "Boarding was one long line that other passengers in the airport had to walk through. This was difficult for passengers with kids and those with needed special accommodations Ike wheelchairs, canes etc"
Pros: "The crew was friendly and polite."
Cons: "The plane was small, it rattled and shook a lot and the size of the seats is ridiculous. The bathrooms did not have warm water and the sense of comfort is to be found only in business and first class. We fly to Zurich a lot because we have family there and we always take SWISS for a direct flight. They have old planes, the little TVs by the seats may or may not work and although the crew is nice and well trained, they cannot substitute for the discomfort of 10 hours flights in a crammed place. Sorry SWISS."
Pros: "Punctual modern aircraft."
Cons: "The onky bad thing was luggage collection. Belt 6 tucked away. The luggage was so quick coming off that there was no-one to collect it . The belt was soon full and no.more luggage could enter the belt until the luggage on the belt was claimed"
Pros: "I thought my out flight with Lufthansa would be good but it was surpassed by the return flight with Swiss Based on my experience I believe Swiss should be a 5 star airline as well"
Cons: "A slight delay"
Pros: "The crew was friendly, the food delicious, and the plane itself in highest quality and state-of-the-art."
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: "Crew are always top notch, free drinks are readily available and entertainment system is great."
Cons: "The food portions and quality have definitely declined over the years sadly, as carriers cut costs no doubt."
Cons: "Food wasn’t great and not a lot of it. London to Orlando was good. Connection was good."
Pros: "The crew was so kind and amazing. They definitely made our flight great!"
Cons: "The entertainment wasn’t working for most of the flight. We only got about an hour and a half of entertainment"

Cons: "It was fabulous as always! Thank you. I love Delta!"
Pros: "Cabin crew and entire experience was phenomenal. Cannot recommend Delta more!"
Cons: "Nothing"
Cons: "Flight into Seattle delayed, flight out of Seattle to Minneapolis delayed flights out of Minneapolis to Bismarck delayed. Ran from gate F to gate c24 arrived at 10:23 p.m. Slight to the park at 10:25 p.m. and they closed the door on me as I was running up there. Ran across the entire terminal to get there and they would not let me on. Last Flight of the night to Bismarck. Missed my uncle's 90th birthday party. Would not give me food voucher. Delta gate agent told me she would lose her job if she did not close the doors 8 minutes prior. However the Minneapolis flight waited for 15 minutes for people to board that plane. How does that compute? Why would they not wait 3 minutes for me rather than pay the money to put me up in a hotel?"
Pros: "Crew, food, flight."
Cons: "Could always use a wider seat. I just hate having my hips touching a stranger for the whole trip."
Pros: "Crew is always friendly"
Cons: "Aircraft broke, had to route me to an additional three stops just to get me home and through the night. Also, still unsure of where my checked baggage is."
Cons: "We weren't alerted there was a chance of delays. Over two hours late."
Pros: "Nothing to like when 1. you are arriving at your destination after 24 hours plus delays. 2. you paid Comfort+ class (not cheap) and are constantly pushed back in the Main Cabin."
Cons: "Actual flights flying on time. What a mess!"
Cons: "It would be great if you could serve warm food instead of bread."
Cons: "No one came with drink carts until halfway through the flight. I was very hungry, never offered food. Boarding was late but no communication from staff."
Pros: "Plenty of movies/shows to watch. Food was pretty good too."
Cons: "It was too hot in the cabin with no fans overhead. The last meal did not allow me to have a veggie option and there was no place for me to order it ahead of time."
Pros: "Nothing"
Cons: "Our first flight got delayed from lax and we missed our connection flight and they wouldn’t let us go on the next flight and instead we had to wait about 7 hours for the next flight!!! Also we got really bad seats on the other flight"
Cons: "- Boarding took too much time because the airline called all passengers to board, instead of asking to board by their seat zone. - The space between seat is too narrow so I couldn't stretch my legs. - The seats are very old and little bit dirty - The seats were not properly cleaned."
Pros: "Food was tolerable. Good cabin temperature. Good lumbar support and pillow."
Cons: "Horrible leg space on the first leg of the journey. Air hostess we'e very inattentive. Asked for a blanket 3 times and still didn't get it. Also they had a poor attitude. Power outlets don't work on multiple seats. Oh and again no leg room. Zilch."
Pros: "Boarding and traveling comfort was good .As always staff were very good and attentive.Food not very good snd boring."
Cons: "Cc"
Pros: "I never usually like plane food but liked Turkish Airline meals on all flights I’ve been on so far"
Cons: "I do like turkish airlines but wasn’t happy with this flight. On check in we were left with seats towards the back of the aircraft. The lady seated neit to us in the aisle seat was in a wheel chair so was a problem if having to get in and out. I didn’t think it was fair that a person who depends on a wheel chair sits so far back on a plane. She also had to deal with our crying baby"
Pros: "three main dishes. chicken. pasta. beef. I donot eat beef and pasta. I request her to give me chicken, but she told me that the chicken is finished. and donot ask me to take any other item."
Pros: "Full meal and entertainment system even for a shorthaul flight."
Cons: "Tight leg room"
