Airline reviews
Pros: "Safe trip and very nice crew."
Cons: "Something to work on is organizing the flights in order when you are checking in. I arrived and it was a mess, we didn't know where to go and which line to take. Please make sure you put signs so we can follow and be more organized."
Pros: "Safe trip and very nice crew."
Cons: "Something to work on is organizing the flights in order when you are checking in. I arrived and it was a mess, we didn't know where to go and which line to take. Please make sure you put signs so we can follow and be more organized."
Pros: "Good crew and amazing always ask if anything I needed."
Cons: "Had issues with specials meals requests. Was unable to get what was requested told both on originating flight, and returning light that its had not been loaded but the request wasn't there.."
Cons: "Plane was hot and sticky. The air from the vent was not cool."
Cons: "Missed my connecting flight due to previous flight being delayed."
Pros: "The flight was on time at departure and 30 minutes on arrival."
Cons: "Since I got a good deal on the ticket, my boarding zone was “Basic”. That kind of sucked, but I still could fit bag in the airplane so it all worked out"
Pros: "The crew was very nice. Quite helpful and pleasant."
Cons: "The only small item is the gate size in MSP. Always a bit crowded but still departed on time so it’s not a large issue."
Cons: "Online check in didn’t work. Called Delta 800# and rep said I needed to wait till I got to airport. Airport rep said I needed to use the KLM flight number, not the Delta number.W"
Pros: "On time. Seat upgraded seat to Delta Comfort plus, courteous flight crew, music before take off and landing."
Pros: "Efficient crew. Good movie choices. Clean bath rooms. However - I wish every airline in each bathroom had a notice on the toilet to PLEASE LOWER THE SEAT AND COVER! I prefer using the bathroom after another woman has used it!"
Pros: "Everything was so very nice. The seats were fantastic in First Class. So comfortable. The service & food were delightful. The only negative was the screaming infant. This is my second trip on Delta in First Class in the past three months. Both times the trip was ruined by crying babies. ☹️"
Cons: "The crying infant."
Did not like . My whole itenery was changed. They canceled my flight. You even did not informed me. Very poor service. Never come back to you.
I liked the whole trip was very good. However the food is getting worse and worse in the flight from the state to Frankfort and vice-versa.
Pros: "Plane didn't crash."
Cons: "Boarding totally chaotic, someone was in my assigned seat, plane was very late, food was crappy, no legroom , seat and armrests uncomfortable , constant screaming babies, smelly passengers, music only came out of one speaker, music kept jumping from one song to another and then back !"
Pros: "The crew was nice and the movie selection was decent. Food was ok. As good as it can be when you pay $2,500 for a flight ticket knowing that they are not really there to offer you a service, they are there to make their own money knowing that as a traveler you really have no options other than an airplane if you want to go across the ocean."
Cons: "The difference here is that in a 9 hour flight you want to keep hydrated. Crew seemed lazy...they would not bring water to travelers very often...and when I called a flight attendant with the button call and politely asked if I could have some water, she seemed pretty annoyed and told me I can just stand up and go take my water in the back where they store food. NOT A GOOD SERVICE FOR $2,500!!!! It’s outrageous!! Seats become smaller and smaller...and you keep asking about my experience...$2,500 to travel seating in a miniature seat with no leg room is a bit much...and I know no flight company cares about this...we have no choice...either take that or don’t travel, right?"
Pros: "Boarding was easy. Flight attendants were so attentive in Premium Economy. Entertainment choices were excellent. There was a USB charging port on the back of the seat. All good!"
Cons: "Suitcase did not arrive, had a 3+ hours layover in Frankfurt, enough to get my bag sorted and sent to Oslo, but did not arrive"
Cons: "Our flight was 9 hours late. We were given no notice of this until we arrived at the gate. it took an hour if holding before we could reach customer service. Customer service at our arrival gate was extremely slow. Baggage claim closed before my daughter’s luggage was released and it was lost until the next day. Our connecting flight was booked incorrectly do we had to spend the night in Frankfurt. Our 13 hour flight took 29 hours. The food was awful."
Pros: "Entertainment was good and varied"
Cons: "Seats were horrible. I'm only 5'1" and the seats were too short. Also there was no room under the seat in front of me so that the backpack that always fits completely under the seat in front stuck out and there was no room for my feet. I could not move. Food nice but pretty tasteless."
Pros: "It was NOT Lufthansa. It turns out it was a United flight. Fortunately they now have individual screens with individual options of what to watch like on other airlines. They did have my special meals as I ordered them. I sat next to a wonderful young couple from Finland. That made the journey interesting and pleasant."
Cons: "I really thought I booked a flight with Lufthansa,which I far prefer than United. They do better with beverages, (Perrier, Pelegrino instead of club soda, better special meals, better model airplanes). I am going to have to figure out how to get a Vegan eal that is not spicy. When I order Hindu Vegetarian it is always too spicy. United also doesn't get it and still gives people cheese or something like potato salad obviously made with mayonaise, and some spread that is either butter or margarine on a sandwich."
Pros: "The hospitality crew that was at SFO gave us the location of a lounge to go to which closed at 8 pm. The time they gave the location was at 8.25 pm. She was uninformed and not very highly trained. Lounge was disgusting. Messy, crowded - seemed like a 2nd class waiting room in an Indian railway station. The boarding was very poorly managed by the same lady!"
Cons: "Lounge, crew, boarding area"
Pros: "The crew were gracious and attentive to keeping us hydrated in Economy."
Cons: "The seats were uncomfortable on this full flight, the food was average."
Pros: "Courteous crew, nice leg room, entertainment system worked, periodical food/drink."
Cons: "I requested a special meal request online but it didn’t go through, and the crew had to find me an alternate meal."
Pros: "Flight space was quite empty in my section so that was AMAZING. Crew was lovely and helped with a few requests for myself and travel companions. Very good selection on tv and movies and the refurbished aircraft was very comfortable for me on this flight. Probably helps having seat to self."
Cons: "Nothing on this occasion"
Pros: "Wonderful to fly on a small airline that still believes in service - a free cup of coffee and a Tunnocks biscuit - whereas many larger airlines charge for coffee etc."
Pros: "They made up some time following a long delay"
Cons: "We were very delayed and no real explanation at first. Also the wrong boarding information was given initially which wasn’t helpful"
Cons: "Initial delay and then take off delay because slot time had not been updated. Our family missed connections. Disaster follow up in terminal!!! So far far we have been over six hours from check in and are still not through immigration. This for an hour flight."
Cons: "The flight attendants were awful. Even before the flight had taken off, I watched one hell at a passenger when he couldn’t find his seat"
Pros: "I liked that the flight was not full, therefore allowing additional room."
Cons: "However food choices and seat room was quite poor. By the time food service was midplane. There was only one food option."
Pros: "I like to fly BA because the crews ( and I assume the maintenance) are top notch"
Cons: "Tired old 747. Needs an upgrade. Packed in like sardines on an old plane that shows it age. Should have flown Norwegian. Major delay caused me to miss my connections though the BA staff were all over it."
Pros: "Despite all the “delays” it actually arrived on time."
Cons: "First it was on time (this morning t-12 hrs) Then it was delayed (delayed incoming flight) Then the plane changed and was on time Then something weird happend, departure was on time, arrival was delayed by 2 hours. Of course, officially there was no delay as departure was still on schedule - but “departure” just means everyone is boarded and plane door is shut, you could still be sitting on an empty stand on the tarmac for two+ hours. Complaints ensued. Captain rerouted plane. Back on time. Arriving at LGW is ridiculous - only 3!!!! THREE! Border nazis manning passport desk for entire south terminal, there must have been at least 700 people queueing. So that delay of 1 hour plus still occurred just within the airport. #ThisIsBrexitBritain #BrokenBritain #PeopleJustDoNothing #NothingWorks #AlexCruzIsACunt"
Cons: "Did not fly cause corona virus. Waited on the phone for 5 hours and did not get someone to help with refubd!"
Pros: "The crew was nice once we got going - after 1.5 hr delay, not due to weather. The delay was per United's Capacity restrictions on a smaller plane: a 737. They kept giving offers to fly tomorrow, starting at $500 and when it got up to $2000, people really responded. Then, after another delay: gone"
Cons: "Communication was miserable. The UA workers tried, but really looked like they didn't understand what was happening. Too bad: wasted time."
Pros: "The crew was attentive and the food was good."
Cons: "Entertainment could have been better. Normally on a flight of this duration I would expect that there would be movie screens in the back of the seats that you could view a selection of movies to help pass the time. This would especially been helpful on the trip home where the flight left at 11:30 am"
Pros: "We landed in NYC -- although it was first announced as Dulles."
Cons: "This flight was on Canadian Air under the auspices of United. I was not allowed into the United Club lounge despite the fact that I had business class ticket. I was informed that a business class ticket isn't sufficient for using the lounge when flying domestic. It is only good when flying international. They call that customer service. I generally avoid domestic airlines because of the customer service. The flight attendants were not happy to serve you. It's a small flight but they didn't even offer a snack -- you had to ask for it. And then they brought over a small basket with nuts, chips, candy bars, and a muffin. I took a muffin and it stuck to the roof of my mouth -- very poor quality. When I asked for a snack the flight attendant replied cocktail or soft drink never saying whether or not a snack was available.. She said this a couple of times before I could repeat that I wanted a snack to which she replied you want something to drink with that. I've been on many short flights in Asia and they will deliver a full meal and you don't have to ask for it. There was no entertainment but United did send an email explaining how I could purchase entertainment to play on my own device."
Pros: "The crew...they were extra nice...keep it up !"
Cons: "I was booked to fly on a lufthansa...but ended up flying United. Paid $ 288 and upgraded to Economy Plus...I thing it was not worth the money. Next time I will travel First Class or Business, either on Delta or Lufthansa"
Pros: "Nothing because we didn’t leave Guam, was not allowed to go Japan due to having a green card and Philippines Passport."
Cons: "Service Overall of how we were treated by a bad customer services is really terrible and bad."
Pros: "Flight was on time and I loved going through US customs in Ireland, so that it made my connection to my USA flight a breeze."
Cons: "Too many crying babies and children. (Flights need a section for young children and infants.) I can handle a 2 hour flight, but not 6+ hours of constant noise) I did not use it, but the entertainment system kept locking up and the flight attendants needed to reboot. If I had been depending on this entertainment it would not have been good. The flight attendants did not come through the cabin enough to pick up trash."
Pros: "I am muslim, but I forgot to arrange the kind of food I would prefer during the flight, and the gentlement I talked to said let me see what I could do to help you about it, and few minutes later came up with muslim meal. I was really happy! Thank you all again."
Cons: "Nothing."
Pros: "Nothing!"
Cons: "Everything! The customer service was terrible and cold. Non refundable tickets should state in huge red writing that they are non refundable!!!"
Pros: "We upgraded to more leg room since our flight to LA was terrible."
the airplane was new and nice. the crew and the food was so so
Pros: "Pleasant crew. Comfortable seats Very nice food. Premium economy definitely worth it."
Pros: "The crew was nice and it wasn't a full flight so we had room."
Cons: "The food wasn't very good and the headphones were a bit uncomfortable"
Pros: "The crew was courteous and efficient."
Cons: "Ordered kosher food, meh. Could have used a little more leg room because I am 6 feet tall."
Pros: "Nothing except that it got me safely to my destination"
Cons: "Food was terrible and there was a long human hair in my beef. Entertainment was one thing only, and it was in Hebrew with Hebrew subtitles. Bathroom was out of TP, not very clean. Crew was abrupt and service was very limited, with one having to walk to the galley for coffee or tea after the meal."
Pros: "Fairly empty flight. Decent movie selections. Pleasant crew."
Cons: "I shouldn’t have upgraded to Economy+ b/c the front row (in Economy) has no where to store your things except overhead, the extra legroom is negated by everyone using your row to cross between aisles and the screen that folds out from the armrest wouldn’t stay upright & required constant adjustment. No WiFi is disappointing for a 12+ hr flight."
Pros: "I reserved window seats on the day of purchases of this ticket and for which I had a printed copy showing confirmation for window seat 24 . At checkin, I was told no history of this was found in a little computer and that I needed to be reassigned new seats . I was furious and very disappointed at elal for temperingcwith my seat and for not finding any sign of it on their data base. It was clear that someone high rank was able to not just take my seats, but erase the memory of it. The only available window seat was 21 Aa, which I had to pay $120 extra for. The irony is that my special meal assignment was not tempered with.... It find this act of ElAl, deceiving, inappropriate, not professional, disappointing, and extremely unfair. The least they could’ve done to award me that seat."
Cons: "I have been traveling with EL AL for 40 years, many Adderall for good reasons. First, the security. Secondly the direct nonstop flight. This particular plane that was a new were version and I’m happy to see that Elal did change the planes and had a great entertainment system."
Pros: "Wanted to fly ElAl"
Cons: "Our light and interactive video did not work and the flight crew could not have cared less. We ended up having to move seats because we couldn’t read with no light after they dimmed the cabin crew."
Pros: "Crew and boarding and price"
Cons: "Charging got coffee is a bit much. NO foot room"
Pros: "Friendly attentive crew , free wine with dinner , excellent kosher food . Boarding and check in process more efficient than in the past Saturday night departure at 10:45 pm convenient for Sabbath observers Reasonably priced as opposed to past EL AL flights Reasonable legroom for coach"
Cons: "Entertainment system hard to work, appeared to be form the 90's , limited choices Unresponsive controls Poor television choices but good choice of movies No WI fi available"
