Airline reviews
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"
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: "The service on Virgin Australia is quite poor. They are barely around. The seats are also only mediocre"
Pros: "Crew was great!"
Cons: "The scone and roll were blah and dry - and so much bread in one meal!!! My seat charger didn’t work :("
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."
Cons: "There was a medical issue and Virgin Atlantic refused to accept the ticket code - for any price - toward a new ticket. I paid for a new ticket and took another airline."
Pros: "The crew were really nice and seemed to genuinely care about the passengers, were approachable and were very happy to chat with passengers and help them out."
Cons: "The food options always seem to run out by the back of the plane and this time didn't match the menu they gave me at the start of the flight, not that I minded because the option I was given was pretty tasty."
Pros: "crew was nice"
Cons: "First time flying with a partner through Delta, so they stuck us on a Virgin Atlantic flight meaning I didn't get my free Delta check in bag (a fee of $60 each way) when I have gotten it every other flight I have ever taken with them. It was also 2 whole hours late in boarding."
Pros: "Food was delicious, consistent timely service and excellent entertainment options onboard. The flight was an hour early!"
Pros: "Crew were friendly and courteous"
Cons: "Poor drink selection. Food mediocre. I felt like I was in the living room of the Beverley Hillbillies. Loud people, dressed like slobs. No manners"
Pros: "Friendly staff"
Cons: "Lack of business class seats and no premium economy seats on this flight"
Pros: "NA"
Cons: "Informing that the flight would delayed by three hours ahead of time would have been amazing. Instead of extending the delayed time every 45 min making us miss all the other opportunities to fly out"
Pros: "Leg room"
Cons: "Not sitting in an airplane without AC for 30 minutes after everyone loaded"
Pros: "Seating and serving, both very good"
Cons: "I couln't get my view on for movies, since there was (I presume) a charge for the earphones. Won't know now what happened to Jean Grey. Maybe offer a small book cart as an alternative entertainment for us cheapskates? do-de-do..."
Pros: "Good seats. Crew was not very hospitable. They went by with water and didn’t give us any. We upgraded for the complementary cocktails and my husband didn’t even get a chance to get one."
Cons: "More attention especially for the upgraded seats that offer complementary things. We got better service in our economy seats on the way to LA. I wouldn’t pay extra to upgrade again."
Pros: "Crew was great, very generous with snacks and beverages, and prior to boarding we were able to switch flights and seats without problem. All the Delta agents were extremely helpful, and had great customer service!"
Pros: "It suited the time i could travel"
Cons: "I felt although they said the two attendants were great they were at best mediocre especially the man"
Pros: "Very fast and efficient boarding process. We began moving right when they closed the door. Smooth flight, friendly attendants."
Cons: "Stop charging $2 for headphones lol"
Pros: "Flight was mostly uneventful, which is great! Right after takeoff we made a complete circle and no information was given as to why, but we assumed it was air traffic."
Cons: "It was so cold! People all over were asking for blankets and commenting on the coldness"
Cons: "The entire time there was a clogged bathroom smell coming in waves. The crew was forgetful of requests. Not a pleasant flight."
Cons: "No internet available (2020). For the my previous flight, a month ago, was the same problem."
Cons: "KLM lost my suitcase and did not deliver it until three days later... They refused to compensate me for having delivered the bag with broken articles inside (A pair of Rayban Wayfarers!)"
Pros: "Onboard crew were nice and polite. Flight was on time (a rarity)."
Cons: "The boarding crew was rude and unpleasant, the plane was boiling hot."
Pros: "Nice staff and no delay"
Cons: "Instead of crisps maybe a bit of cheese or crackers"
Cons: "Flight 2 hours delayed, started boarding but had to wait on line 10 more minutes on boarding ramp for plane door to be opened, upon landing in Dublin had to wait on tarmac for anther 15 minutes for stairs to arrive and be connected to airplane. Then had to wait another hour for checked luggage...."
Pros: "The crew is really welcoming"
Cons: "The seats are too narrow and a bit too hard"
Cons: "The flight was cancelled and had to be rerouted on United Airlines."
Pros: "Last year I flew Lufthansa which was my worst experience flying ever. I thought the new standard was so low I would never fly to Europe again. I had heard KLM was good but I felt this was as good as could be expected actually much better. The food was even good."
Cons: "I would have to dream something up."
Pros: "Crew was excellent -kind nice and very attentive"
Cons: "Entertainment went out mid flight. Had to be reset off 30 mins but cam back up"
Pros: "Efficient crew"
Cons: "Long, slow line at check in. Not many new movies or tv shows"
Pros: "The seat was really comfortable and I was able to sleep the whole flight with no disturbance"
Cons: "N/A"
Pros: "The sear was messy they didn't clean it it was full of pieces of bread."
Cons: "boarding the flight on time instead of delaying it two times... and also putting the information at the flight information screen if I haven't gone to ask to the airport information stand I would never know the flight departure gate that was at the complete opposite side of the airport of were the initial flight was going to depart."
Pros: "The seats were bigger across the shoulder area and had more padding than some other budget airlines."
Cons: "Wish there was more elbow room in the seat. I am a big guy and I was having to squish myself so as to not interfere with my neighbor"
Pros: "Exit row seat had much more space for legs, very much worth the upcharge for this seat."
Cons: "Cabin temperature was very cool for me. Never used a blanket on an international flight before, and used a blanke on this whole 9 hour flight. Maybe a function of the seat location? Not sure but I was cold."
Cons: "First class bathroom could have been cleaner and wider - very narrow, hard to maneuver"
Cons: "I’m not sure that short-hop flights should serve solid food. The quality invariably disappoints. Otherwise, all is good with this flight."
Pros: "Good crew, as usual with Air France."
Cons: "Old plane with very lousy seats for a super expensive business class. Super slow check in and overall process till boarding because of lack of ground staff compared to passenger volumes"
Pros: "The flight departed on time and arrived early. The crew were all courteous and kind even to the man who was sitting next to me who seemed quite demanding."
Cons: "I am small but the seats seemed a bit too tight. The plane itself seemed a bit outdated."
Pros: "Food and drinks very good"
Cons: "In economy class the movies unable to listen to with ear buds. Bring my own next time."
Pros: "Crew and food were great."
Cons: "Old plane. Seats were super tiny and uncomfortable. Couldn’t sit in the same spot for longer than 15 min without getting sore."
Cons: "Told us to pick up stroller in Dublin. Get there and we are told that is not possible. Of course we not have arrived at our final destination without said stroller. Seats are on the pitiful side of the spectrum and gets a bit old being nickled and dimed for drinks, sodas, food. . ."
Pros: "Food was excellent and the movies were free."
Cons: "Our seats wouldn’t lean back. Other people’s did however."
Cons: "Neither wi-if nor the movie system worked. Fortunately we had strong tail winds so an 8 hour flight was 6. They should have let us know while we were still in the terminal so we could purchase a book or download a movie. Beer and wine had to be purchased on an international flight. No economy plus."
Pros: "Friendly and helpful crew. We were served drinks and food. I liked that the flight attendants requested everyone put their seats in the upright position anytime food was served so that the person sitting behind you had space to eat."
Cons: "Seats were uncomfortable (in all fairness, most airplane seats are uncomfortable!)."
Pros: "Very comfortable seats and excellent onboard entertainment. Friendly crew"
Cons: "The breakfast burrito was not good quality. Also, gluten free options would help me"
Pros: "The pretzels."
Cons: "The customer service from Aer Lingus is the worst ever. This is our honeymoon and it got ruined. The flight was 3 hrs delayed, and they started rerouting people that had connection flights to London, we had a connection and randomly Wendy the service agent decide to not reroute us because we had plenty of time, of course we didn’t make the flight, we have been hostages of Aer Lingus for the last 21 hrs so far, but more will be added until we make it to Hamburg tomorrow at noon instead of tonight at 8."
Pros: "Plane was clean and comfortable."
Cons: "Plane arrived late - no updates from the gate crew. ...coffee and soda is not free..."
Cons: "- My seat was broken and could not recline. This not only made the 9 hour flight uncomfortable, but even more so when the person in front of me reclined their seat fully. - I understand it's Aer Lingus' policy, but I have never experienced--in my many travels--paying for alcohol on an international flight, especially cash only. - Regarding the above, I had to remind the flight attendant three times that she owed me change, and each time I was greeted with a sneer and, "Yea, we don't have it yet". It was not so much the money, but the incredibly rude service and charging for what should be a free drink! Some of the stewards (on the opposite side of the aisle) seemed very friendly and accommodating, but unfortunately, the two ladies on my side made me feel like a burden rather than a welcomed customer. - I guess it's, you get what you pay for...but I was just surprised at "breakfast" being tossed a box with a burrito--no napkin, utensils, plate, nothing. I won't be flying Aer Lingus again."
Pros: "Entertainment was the best thing about this awful airline flight."
Cons: "Food was awful. Worst Ive ever had in around 200k miles of flying. Food service was rushed. i.e they asked me if I wanted coofee or tea immediately after serving my main meal. My son was feeling unwell due to asthma and asked for water. He got a lesson in manners and etiquette as he didn’t say please. I asked another female staff gor water. She didn’t respond so I waited a few minutes before askinfg again. She snapped ‘ I heard you!’ Made me feel uncomfortable asking for anything and that I was a nuisance. Seemed they could hardly wait to serve dinner and turn the lights off. I’ll be taking my own food on the return flight. I’m not expecting gourmet on an airline however this food was inedible"
Pros: "The seating was comfortable"
Cons: "The fact you even had to pay for coffee is absurd . There also should be some in flight entertainment"
