Airline reviews
Pros: "Courteous and attentive crew from baggage check in thru baggage claim."
Pros: "Courteous and attentive crew from baggage check in thru baggage claim."
Pros: "Nice crew"
Cons: "Comfort. Seats were very uncomfortable with absolutely NO leg room. I fly a lot and this was one of the WORST leg room experiences I had."
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: "Nobody are better hosts than the British. Great service, lovely people."
Pros: "The flight crew was phenomenal, especially Daniella. Somehow we wound up with seats right next to the bathroom door, which would have been a pretty uncomfortable situation for a variety of reasons, but the flight wasn't full, and she helped us find a suitable place to sit. Also, my wife and I usually take our tea with honey vs. milk and sugar. Even though honey is usually one of the options for tea, she found a way to accommodate our request. The lunch meals were the best I can remember in a long time on an airline flight. They might have been the best I've ever had. The chicken curry was authentic, flavorful and spicy. Frankly my outbound flight had problems. My luggage got damaged. The transfer experience in Manchester left a LOT to be desired. I wasn't planning to use Virgin Atlantic again, but this flight crew (Daniella especially) redeemed Virgin Atlantic. They were attentive, pleasant, diligent."
Cons: "Only thing I didn't like about this flight was the boarding area. Once you get into that the area, you don't really have access to appetizing food (only vending machines) or even restrooms. That's one thing that could be improved."
Pros: "Great movie selection"
Cons: "They need softer seats...had to stand half the time"
Pros: "Friendly staff, so much food/snacks were offered. Good movies available."
Cons: "Nothing"
Cons: "Why do I have to get a new boarding pass in London"
Pros: "We really enjoyed flying with Virgin and so made sure we booked into a Virgin flight for this trip and not delta. The food was good, entertainment good when it worked."
Cons: "We got told that our flight number had changed from VS103 to VS4049 but still a Virgin flight. Only when we checked in we found out we were now flying with Delta and number was now DL285. Was not happy as wanted to fly with Virgin.The seats were ok but the entertainment system went down mid film. Took an hour to get started again. The games didn't work. Staff were a bit grumpy."
Cons: "We were told over the phone that we could bring our kayaks with us to Africa but the airport staff denied not only our kayaks, but also our paddles which were in a standard ski bag. Their excuse was that both the kayaks and paddle bags were 2 inches too long. .. TWO INCHES!!!!!! We had record of the person we talked to and the time and date, but none of that seemed to matter. It caused A HUGE INCONVENIENCE for us since we are in Zambia for 6 weeks without our gear to paddle one of the most challenging rivers in the world... the Zambezi. Now we are constantly trying to acquire the proper equipment with very little success. We run a nonprofit called the Montana Kayak Academy which provides free whitewater instruction to youth between 8 &18 yrs old and we will be sure to tell everyone we know to NOT TRAVEL WITH EITHER VIRGIN ATLANTIC OR BRITISH AIRWAYS.... EVER!!! VERY DISAPPOINTED! !!!!!!!!!!!!!!!!!"
Pros: "Packed flight. Ground crew did best to minimize carryon luggage. Flight crew were accommodating and cheerful despite almost 1H delay in departure."
Cons: "Pilot had no control over turbulence during last 3H of flight. He did his best to minimize but still a jittery"
Pros: "I flew standby (for the first time) to London and check in team in NYC was great."
Cons: "Now, the team in London, wasn’t so great. They were a bit rude!"
Pros: "Entertainment was good and there was a choice of food."
Cons: "The crew sucked."
Pros: "The A330 was comfortable and the crew was efficient and cheerful."
Cons: "Delta is the best experience we've had of late."
Cons: "KAYAK did not informed us we have to pay for our luggage!"
Pros: "Food was great. Movie selection was good."
Cons: "When we booked our flight, we were not informed by KAYAK that we have to pay for our luggage! I t was very unpleasant surprise both ways."
Cons: "Wifi was completely useless. I prefer to pay to get simething."
Pros: "I had an awesome seat 10a with plenty of leg room."
Cons: "It was as good as can be expected."
Pros: "Crew was nice. The tv/movie technology was fantastic!! Huge selection of movies that made the time fly by, and very easy to use as opposed to my other flight over. Food was good. I love that you get tons of food and drinks (more food than I could eat actually)."
Cons: "I couldn't get both of my boarding passes printed in London so I had to get it from an agent in Minneapolis. I hate that it's so hard to get a seat assigned and a boarding pass before the trip."
Pros: "The delta crew both ways between Portland and London was excellent! They saw to our every need and were smiling every air mile of the way. Plane"
Cons: "Need to have food choices available for those with allergies. Almost everything had gluten and soy in it and I am very allergic to those. I had to give away all snacks and most of my food. Even in comfort+ class the seats are tiny with little legroom. Also, please clean the bathroom every few hours"
Pros: "The crew was very attentive and willing to assist with everything."
Cons: "They charge for coffee and soft drinks and have no snacks complimentry"
Pros: "Price for seat was very good. We left 30 minutes late but arrived early."
Pros: "Ability to quickly board the plane"
Cons: "You had to pay for snacks and drinks on this flight"
Pros: "The air hostesses were first class. Pleasant, efficient and professional."
Cons: "The tv selections. Could have had more variety"
Pros: "Crew did a great job!!"
Cons: "Due to the age of the plane there was no outlet to plug in your phone."
Cons: "On a flight to Budapest, budapest airport had issues that forced us to land in Austria. 5 hours later we’ve been completely abandoned in an empty airport while all the other planes that landed paid for their customers transport. It’s 4am, we have not been given food water or a plan as to how we will get to our destination. The plane crew basically told us we are on our own and left. This is straight up cruel, unjust and completely unacceptable considering we paid more than 2000 dollars for these flights"
Pros: "The flight crew was amazing. The entertainment system was great"
Cons: "Landed almost an hour late. Food was HORRIBLE. worst pasta of my life. The crew while kind, we busy chatting in the galley most of the flight. Never came around (besides the initial drink cart and the meal) to offer water or check on passengers. They forced me to close the window while we were flying and I bought a window seat so i could look out. The boarding process was very slow and disembarking took ages. Problems with loading the baggage led to an issue at baggage claim where they were stuck."
Cons: "They didn't give a direct flight but gave to Mumbai and then from Mumbai to Hyderabad. Had to collect my luggage and recheckin those."
Pros: "Six years ago, after a very bad experience with this airline, I swore never to use BA again. However, this year, because of my children, I found myself on this airline again and had a very positive experience. The flight was on time, luggage was transferred without a hitch, the food was excellent and in-flight entertainment had a great variety to choose from. The 747 provided a very steady flight experience. Personnel were reasonably helpful. Continue this kind of service - it will help you remain successful."
Cons: "Had to want in aisle to go to bathroom while beverage cart took forever to get to the back of the plane. Line was 12 deep to get there."
Pros: "The crew on board seemed efficient and friendl for this short 2.5 hour flight."
Cons: "No food, no drink, no entertainment were included with this fare. Thankfully we were so exhausted from the long haul flight immediate preceding this flight that we did not care. I'm not sure why but the gate staff was trying to get everyone to check their smaller bags including our backpacks. My husband gave in but I did not since not having them would be disaster during this trip. His backpack and many bags from other customers came about 15 minutes after the rest of the luggage so we were a little panicked. Thankfully all turned out fine."
Cons: "Were not there to rate but someone paid you an extra fare so you made double the money on one 2 seats! BRAVO Standing Ovation!!!"
Pros: "Finally arriving in Spain."
Cons: "The seats are extremely small cramped and I had to sit with my legs in the aisle. The flight attendants didn’t care about seat assignments so they put people wherever they wanted, causing issues when those people were in others seats. No in flight entertainment (zero stars). No complimentary snacks; had to pay for everything. Decent selection of food. The entry attendants were inconsistent with hand luggage size and took my correctly size soft bag to check but allowed larger hard luggage on the plane."
Pros: "The flight was on time."
Cons: "The plane was in bad shape, dirty and the seats were very worn out. There was no entertainment."
Pros: "Left on time."
Cons: "Plane is extremely old and should be put to sleep. Business class on this plane means younger an empty middle seat and narrow standard seats. Not worth it for business, check airplane model before you book."
Pros: "Price to fly on this airline is very reasonable and affordable. I would fly on on this airline just for that reason alone."
Cons: "Seats are VERY small and squished together."
Cons: "There were delays at Heathrow due to fog. Rather then backing up all planes by an hour or so, BA gave our plane away. We experienced a 6 plus hour delay. So after flying for nine hours from the U.S. overnight to London, we had to sit around the airport, while watching other planes take off on time. We got in so late to Madrid that our hotel room that we reserved months earlier was given away. After being awake for over 24 hours we had to walk around Madrid at 11:00 pm at night, looking for someplace to lay our weary heads."
Pros: "The captain and the entire crew handled an accident very professionally. Seats in economy class were much more comfortable than the ones on my previous, rotten BA52 flight."
Cons: "We get to the runway, wait 10 minutes and go back to the terminal. The captain announces an engine failure. Maintenance inspects the leaking engine, do something and declare it fixed. 2 hours delay and my nerves a bit shaken during take off. We arrived safely."
Pros: "The discomfort of the cramped seating overshadows everything"
Cons: "This was the 3rd time I had to take Iberia coach in Europe in 4 week. As horrible as the first 2 times. The rows are too close to each other. I can not sit straight. My knees hit the seat in front of me. I was not the only one measuring more than 6 feet. Other men equally were obliged to sit sort of diagonally. It a real torture. Horrible. Never again."
Pros: "Seats weren't too uncomfortable, and the crew was friendly."
Pros: "Customers service. The crew was awesome. They're good to me when I was sick."
Pros: "Everyone was pleasant and helpful, food was good and plentiful."
Cons: "I was not given my handicap assistance that I requested."
Pros: "Great aircraft, UK staff kindly assisted to get us family seating near each other"
Pros: "Flight departed on time. Meal was hot and tasty. Friendly crew."
Cons: "Insufficient arm/legroom. Limited selection of interesting movies."
Pros: "Friendly crew"
Cons: "Movies selection poor and games could be better and touch screen not working properly"
Pros: "The seat was comfortable for such s long flight (~10 hrs). The selection of movies/television/music for personal use was exceptional. Being provided a lightweight blanket & small pillow a nice touch. Beverage service and a small unexpected VIP of ice cream a very nice surprise!"
Cons: "Didn't like being served dinner-type food (pasta & salad) late morning….but I shouldn't complain since it was a privilege yo be served a meal.Didn't like being told my window shade had to be closed I chose a window seat so I could look out the window and have natural light. It was daytime. As there was no one sitting next to me, I ultimately kept the shade partway open. I could tell the crew was irritated. Several hours later, a different FA came over and just shut my shade; I reopened it. What a stupid tug of war."
Cons: "It was FREEZING. Uncomfortably so that we were unable to sleep."
Pros: "The plane was clean, leaving on time, with fewer passengers there was much room and the service was surprisingly friendly for an American Airlines flight."
Cons: "The crew had a light task with the fewer passengers on board and they made the best of it... not neglecting the passengers, but definitely looking out for themselves and that was a bit obvious by creating small cabins for them to stay in using the curtains near the door exits and encouraging people to move to empty rows to clear the back rows for them to sleep on. Not bad, but just a bit obvious."
