Cons: "Soda or coffee served during the flight could have enhanced their service."
Pros: "Old aircraft showing its age."
Pros: "Fast easy flight"
Pros: "The crew was amazing and smooth flight"
Cons: "No entertainment option was avail except WiFi (T-Mobile) which wasn’t free"
Cons: "90 minute delay"
Pros: "all good"
Cons: "unsure"
Pros: "NOTHING."
Cons: "Missed the flight due to the sheer unhelpfulness and incompetence of the gate personnel. They would not let me board, since I was about 10 minutes late. THEN THE PLANE WAS DELAYED FOR ABOUT 2 HOURS!!! I was stranded in NY, overnight, and had to pay hundreds of dollars for a train ticket and a cab."
Pros: "Crew was nice"
Cons: "It would have been better if the flight wasn’t 3 hours late."
Pros: "The check in counter personnel was VERY UNHELPFUL. I was running late to previous Delta flight baggage delay. The counter person would not let me check in even though I still had good 45 mins before take off. AND THE PLANE WAS DELAYED BY 40 MINUTES ANYWAY! I never made the flight, had to take train."
Cons: "The entire Delta customer service was a nightmare. Delayed flights, literally lying supervisor who escalated a dispute, absurdly poor service. ASSISTING A PASSENGER WITH A TRANSFER TO ANOTHER DELTA FLIGHT AFTER THE FIRST ONE WAS DELAYED IS "NOT A GUARANTEED SERVICE". Seriously, it is basic courtesy!"
Pros: "The flight was on time and quick."
Cons: "the number of kids......not too fond. :/"
Cons: "Excellent"
Cons: "If there could have been some sort of services to take travelers to their connecting flight, for cases of really short time window of course, it’d be extremely helpful."
Pros: "Smooth flight. Everything was great."
Pros: "I always appreciate in-flight television even on short flights."
Cons: "Very tight seating."
Pros: "I love Delta! Always professional, efficient and polite. They disappoint on this round-trip flight. They are my go-to carrier. When I call the people whom I speak to are always very polite and efficient"
Cons: "The person next to me was a very large individual and the seats were not wide. This phenomenon had nothing to do with Delta as a carrier, however."
Pros: "Everything was great everyone was fantastic. F"
Pros: "Not sure why this flight was delayed inbound. But it made the departure late by over 30 minutes."
Pros: "Seats are comfortable and didn’t mind staying with the back upright. Flight attendants veery friendly and boarding was fast and easy."
Cons: "Headrest was too short and there’s no seat back screen. More communication from the cockpit at the end would have been nice. Announcements were very hard to hear over the background plane noise."
Cons: "Never told why we were delayed by more than 90 minutes"
Pros: "The Delta Help Desk at the airport was actually pretty helpful for the times I had to use them."
Cons: "Flight was delayed....3 times(more?) from late at night to early morning the next day. Delta Help Desk rescheduled me and got me a room at Howard Johnson’s for the night. Called HoJo’s to confirm they had non-smoking rooms available. Got on the hotel’s shuttle bus and the driver announced that HoJo was full and all voucher holders would go to Rodeway Inn but those without vouchers would go to HoJo....huh!?? Called HoJo and the same person I’d spoken to 20 mins prior said it was correct, that Rodeway was a sister property. The Rodeway Inn Metro Airport is pretty disgusting. This is my opinion after coming from remote Mexico and extensive travel in Africa. It should be torn down. Delta/HoJo should not send customers there."
Pros: "Everyone was friendly and got us to our destination"
Cons: "None"
Pros: "Nothing"
Cons: "No food, no outlets, a terrible delayed not explained to passengers."
Pros: "Nothing.. the entire experience was horrible. Nasty seat. Had to get rebooked 3 times to finally get home but had to fly into a different airport and you also lost my bag so I have nothing to wear to my father's funeral."
Cons: "Everyrhing. the entire experience was horrible. Nasty seat. Had to get rebooked 3 times to finally get home but had to fly into a different airport and you also lost my bag so I have nothing to wear to my father's funeral"
Pros: "Quick flight"
Cons: "Unexplained delays, lack of transfer services (there was no separate connections security screening; passengers were required, after a redeye flight and customs, to switch floors and stand in long lines with general security. Also, no beverages of any kind were offered."
Cons: "The airline booked us on two flights from SLC to BWI. Unfortunately, our seats on our original connection were released so when we arrived at our gate our only option was to split up and take middle seats - even though we had paid over $100 ea. for upgrades. Delta offered nothing for this. One of the flight attendants was in a terrible mood - she was cold and rude and would not even look at passengers - which her fellow crewmates noticed and tried to compensate for."
Pros: "The staff was wonderful and the flight was smooth"
Cons: "N/A"
Pros: "Quick boarding"
Cons: "Seat was very cramped and I want able to be comfortable at all. I couldn't even sit back I the seat!"
Cons: "JFK was depressing but not Delta’s problem."
Pros: "Delta is not a good place to be"
Cons: "Delta is not good on customer service"
Pros: "Snacks & beverages on a 1 hour flight. Very nice crew"
Cons: "Older plane, no entertainment"
Pros: "Kyle was our flight attendant. He was great. Attentive the whole trip and served us water and snacks."
Pros: "I missed my flight and was not able to rebook any of it, losing 600 dollars..."
Pros: "Nice crew, comfortable"
Cons: "Had to check in my carry on because there was "no space" left but after me were some people who could go in with their carry ons"
Pros: "I am 6’3” and have difficulty with leg room on planes. Staff help me out by moving my son and I to Comfort seating row."
Pros: "That the planes flew and i met my connections and arrived home."
Cons: "Below average crew with little to no interest in doing anything but getting the flight over. Cool, and perhaps lazy or tired. We were told there was not good offered on the flight because it was not long enough. Minneapolis to Spokane - seriously????5 days earlier on same flight there was full food offerings. Audio quality and ear bugs are barely useable. Very difficult to hear any of the spoken words of the movie and I have good hearing."
Pros: "Where the flight attendants on my AeroMexico portion were authentically compassionate, the flight attendants for delta were superficial. The flight attendant,while serving us drinks, started saying what great passengers we were but her flight from Dallas the day before was definitely a feeling the effects of the full moon. This was our first interaction with a flight attendant. She had no basis for saying we were great and as we didn't have a relationship other than ordering drinks she had no basis for complaining about her Dallas to us. She would leave it to us that she was being put upon by the customers that she was getting paid to serve. Where the Aeromexico flight attendant genuinely enjoyed serving her customers."
Cons: "They forced everyone in the third zone to check our hand carry and there was no entertainment."
Pros: "Nothing"
Cons: "Terrible staff"
Cons: "Whatever hack airline you are contracting with to do shuttle flights is terrible. Both the flight itself and the customer handling. If I ever see the option "operated by endeavor air" I am avoiding at all costs."
Pros: "very little"
Cons: "Could they make sears smaller? The plane was really old too."
Pros: "The crew was nice and helpful."
Cons: "The economy plus wasn't nearly as nice as any other airlines. It gave the least amount of extra leg room and the only other amenity they gave was a toothbrush. Even United economy plus is bigger. Plus if you want to change anything you have to pay include just to try and go stand by on an earlier flight."
Pros: "Had a chance to download the entertainment app during layover, so could take advantage of movies available on second flight. Crew still good; gate attendants friendly; snacks/drinks readily available."
Pros: "Comfortable seating and roomy"
Cons: "Nothing"
Pros: "Excellent flight crew, good selection of snacks, excellent seat and leg room."
Cons: "Lavatory was unusually smelly no charging port"
Pros: "Delta is definitely the jewel of commercial airlines. I understand making money depends on how many bodies you can transport at one time. But as a large man the seat size and leg room could be improved. I unfortunately cant afford first class to remedy this problem."
Pros: "Getting on board was smooth and efficient. Service was friendly on flight. Arrived on time."
Cons: "Not applicable."
Cons: "My flight from ATL to BWI was horrible. It was not a Delta plane. Possibly borrowed from SpiritAirlines, which is an airline I will never fly again even if offered a free flight. That's how strongly I feel about their planes and service. I was seated in a 2across row where the seats were small and my knees were jammed into the seat in front of me the entire flight. I'll grant you I am a big girl at 6' 250 however the first leg of my flight from FLL to ATL which WAS on a Delta plane, was fine. I did not feel smashed into the seat. For the money, I feel like I am due more than being locked into the seat unable to move more than 1/2 inch for an entire flight. Thankfully the flight was under 2 hours."
Cons: "After checking in at a kisok I had to wait in a huge line for over 20 minutes just to drop the bag. This the second time I have had this experience with them."
Pros: "Nothing to speak of. Nothing exceptional from any other airline - basic"
Cons: "Our carry-on luggage was taken away from us because the gate agent decided it looked too big. A family of four with luggage larger than ours was allowed to carry theirs on. Our luggage was then sent down to the baggage carousel at Baltimore. We took carry-on to avoid this. I don't think we will fly Delta again."
Pros: "We arrived nearly on time & without issue."
Cons: "The plane was warm & no cool air was being dispersed in the cabin & because of that it was very dry. Better temperature regulation, climate control is needed to make fir a more comfortable flight."
Pros: "Seat was small but comfortable. Everything went smoothly."
Cons: "The plane was very cold"
Pros: "Food was delicious!!"
Pros: "The crew and the entertainment were excellent."
Cons: "The seating area is very tight and the aisles were extremely narrow."
Pros: "The attendant at the desk was very accommodating towards my needs."
Pros: "They smiled, gave a friendly farewell, made sure everyone was hydrated."
Cons: "Don't get an attitude with calm passengers asking for assistance for their seatmates. Sometimes they wouldn't ask me what I wanted to eat or drink, they just assumed I already heard them ask other passengers and just waited for me to answer. It just seems lazy to me."
Pros: "Lot of leg room!"
Cons: "WiFi for Entertainment system was spotty, freezing very often. Unfortunately this issue has become more common in United flights lately."
Cons: "Totally false information provided by Kayak re: seating and seat assignment. Sold as Austrian Airlines flight w/ links to their baggage policies and ability to pick seat. Arrived at airport and told I must check in with United, who charged me baggage fees contrary to Austrian policy."
Pros: "On time"
Cons: "Impossible to get entertainment to work"
Pros: "I like flying Lufthansa for entire trip then changing to united airlines"
Cons: "Particular everything the airline"
Cons: "I missed having the navigation map when traveling such a long distance."
Pros: "Brought my own entertainment. Friendly staff. Great boarding process. On time departure"
Pros: "Seem to be a smooth and direct flight"
Cons: "The flight was fine however my seat was next to the bathroom and people would occasionaly Bump in to me ."
Pros: "Did not have any food so an N/A option for this category is needed."
Cons: "The exit, economy plus seat I chose was described as limited recline when it fact the chairs do not recline at all. I was so disappointed. Had I known this, I would have chosen a different seat. My neck was hurting by the end of the flight."
Pros: "Flight was on time. Friendly crew."
Cons: "It turned out that we were on stand by (without anyone telling us until the morning of the flight) and did not know if we were going to fly out. We could not select any seats at check in and only found out our seats a few hours before the flight. It was quite unpleasant and stressful as my husband and I were flying with our two children and faced a real possibility of not being able to sit together or getting bumped off a flight all together. It was a code shared flight between Lufthansa and United and each airline kept sending us to the other to get any answers or help. neither were helpful. It made it for an extremely frustrating experience."
Cons: "My parents were traveling, they dont speak english and I verified with Austrian airlines that they would be assisted at the gates and that they had the correct visas for each airport they had a layover in. I was assured there would be no problems. Upon boarding they were not able to get on their flight. I have never had so many communication issues and frustrations in the middle of the night with an airline. disappointed."
Pros: "The boarding was quick and the flight was on time. The crew was courteous."
Cons: "I selected economy comfort in the kayak app, but when I called about my boarding pass, kayak said they only sell basic economy. What did I buy? UAL only sells a limited selection of overpriced food. There is no music and you have to pay to see the flight map."
Pros: "The boarding and seating happened in a timely fashion, and the crew was courteous. The lunch meal (I had requested Asian vegetarian) wasn't amazing, but not as bad as it could've been."
Cons: "The flight was not with Lufthansa, but it was actually through United, which was extremely confusing as I did my ticket confirmation, seat booking and meal choice through Lufthansa prior to my trip. To find out on the day of the flight that I had to check in and go through United was extremely annoying, as the counters are in different terminals and it was unnecessarily stressful. The flight itself was crammed, with absolutely no leg space, and not even enough space under the seat to stow my backpack (which had fit perfectly on my Brussels Airlines flight to Madrid). I had requested the Asian vegetarian meal, and the snack we got prior to landing was pretty much two slices of cucumber on a small bun (and an apple on the side) - extremely dry and hard to eat. I asked for mayo, but the flight neither had that, nor any other condiments to make the "sandwich" more edible."
Pros: "plane was relatively quiet and comfortable."
Cons: "Nothing wrong with boarding a plane using a bus, but there are better technologies and they are better."
Cons: "I was unable to go on the flight because of the extraordinarily high cost of changing a last name from a maiden name to a married name. I was so disappointed by the service."
Pros: "I upgraded to premium economy and was glad I did. Extra space and and empty chair next to me."
Cons: "For a 9 hour flight, food wasn't filling nor was there enough. I wouldn't have even minded paying a little extra for snacks but a small dinner and small sandwich as a snack was all there was. Plenty of drinks though. My day did not recline all the way, I only got it to move an inch or so."
Pros: "This flight was a good value."
Cons: "My legs are short and the seat seemed a little higher than other plans. I couldn't rest my feet flat on the floor for 6 1/2 hours. This was very uncomfortable."
Pros: "Crew was helpful."
Cons: "We were sitting right next to the crew resting area and it was very restricting to us. I had two little kids that I had to keep quiet for about 6 hours out of 8. Even when my kids were quiet, we were reminded twice to keep quiet. It was very restricting and I was forced to walk back and forth with my two year old to keep her quiet so the crew can rest. Why is the crew resting when they are supposed to be working on that flight? The meal quality sucked, I did not finish it, let alone my kids. My kids were prettu much hungry for 8 hrs. Not a very family friendly flight."
Pros: "Good crew!! Entertainment screen not as good as SAS"
Cons: "The crew was haughty and rude, my purse was taken and stowed in overhead storage, the person sitting next to me wouldn't stow the carry on luggage. I needed to take my daily medication during the flight and was not able to. I have chronic health issues and needed to take it on schedule, I was delayed in getting home because I had to stop and eat in the airport and take my medication"
Pros: "Service Cleanliness Food Entertainment Boarding"
Cons: "Length of Flight"
Pros: "The flight attendant used my name. Great landing."
Cons: "Tar mat loading. In flight service."
Cons: "can't believe you still have those low quality touch screens. they are very non-touch sensitive, and don't respond well to attempted touch commands."
Pros: "Good flight"
Cons: "2 Delays"
Pros: "Everything good. Thank you"
Pros: "The flight was on time."
Pros: "We liked the crew, they were helpful."
Cons: "We did not like the video on the United flight that used the app. We were not told about this until it was too late and the instructions were not good for how to get the app--they were misleading. I had to go to the app store, not the United website. Also, our seats were changed without our knowledge and the flight description for the flight from Austin to Washington, DC, specified complimentary lunch and there was no lunch unless you wanted to buy it. This should be more clear, so that I can bring my own lunch if there will be none provided."
Pros: "The service was amazing."
Cons: "It was a bit difficult to navigate my way in Munich but the staff was helpful. I would suggest a 2 hour layover."
Pros: "Seats were comfortable in exit row."
Cons: "Flight sat on runway for over an hour."
Cons: "Choppy"
Pros: "The ground & flight crew was wonderful and accommodating"
Cons: "I wasn't allowed to bring in my carry-on luggage I was forced to check it in. We were told the compartments were fall once we boarded there was plenty of space in the luggage compartment it was a bit disappointing. I think the entertainment is overpriced as well"
Pros: "I lost my wallet on the plane to San dieago. A very nice honest family turned it over to the crew. The baggage claim customer service agent ran back to the plane to retrieve it for me. It had everything I needed, my ID cash for my trip. I'm thankful for the honest people still in this world! Many thanks to the family and crew and uninteds customer service!!! A+++++"
Pros: "the United app that let me watch movies from my own device. The flight attendant gave me an extra blanket."
Cons: "the plane was very old and didn't have the entertainment options that newer planes have. The screen was so small and nearly impossible to see when the person in front of me reclined. The toilets weren't very clean. The food was very mediocre. I have a dairy intolerance, and both options contained dairy products. There was no lactose free or diabetic special meal option. There was an hour and a half delay to repair something on the plane when we made an emergency medical landing in Boston. I didn't mind the landing; I minded the excessive delay and wonder what would have happened if we didn't stop in Boston? What would have happened to the plan?"
Pros: "Flight wasn't that long. Experience was okay. Flight was full. Attendants did their job. Some were more polite and helpful than others."
Cons: "No request was made for the outbound flight which I want to comment about. At Dulles Airport, I checked in at the Brussels Airline counter, only to be told that since I was on a flight operated by United, then I had to go to the United Airlines counter to check in. At UA, I was handed a boarding pass which advised that my seat will be assigned at the gate. I saw on the monitor where the available seats were-1 window, the remainder middle row. I got the feeling that since I bought a ticket which cost less than what the other United Airlines customers paid for, then I was being relegated to seats that the other travelers didn't desire."
Pros: "Having movies is the best, followed by pillows and blankets"
Cons: "Stressed and unfriendly attendants (except 2). Didn't ask meal preference, just gave me chicken and I had to ask for switch. Would say things like "I don't have time" and "we'll do it later when the cart comes around". Only had 1 drink service, I don't think they made it all the way to my row. Very different than flight from USA to Paris."
Pros: "Offering food and drinks as part of ticket price, on-time departure, efficient service."
Cons: "More leg room without extra fees."
Pros: "Comfortable seating, great staff, food was pretty decent, they were very accommodating and had sufficient drinks and snacks through the flight. I would highly recommend Brussels Airlines."
Pros: "The flight was on time and smooth, crew were friendly."
Cons: "It was freezing cold in the plane. People were putting on sweatshirts and jackets and covering up with blankets. Why should we be required to bring winter clothes with us when plane interiors are temperature-controlled?"
Pros: "...I got the standby flight....I guess that's cool..."
Cons: "My red eye was delayed35 minutes because of wheel replacement making it impossible for me to make my40 some odd minute layover and I had to burn up hours of my vaca in an airport and reschedule a pick up."
Pros: "The crew was very attentive and the pilot kept us informed at all times. For example, we got to Dayton early and we sat on the Tarmac for about five minutes as there was another plane there. That was no problem. But, after plane left we sat there until it was time for us to arrive before ground crew came out. Then, we waited 20 minutes for our baggage. That was not your fault. That was the fault of the airport as it has happened to me before. The pilot was very apologetic and kept us informed. I appreciated that very much."
Cons: "I was so excited because there were TV's on each seat, but I could not use because the place where I had to plug in for sound was broken. That was a disappointment."
Pros: "My other passengers in First Class. Your crew was also very kind and well mannered."
Cons: "I spent over 150 for an upgrade for a red eye for a flight I already spent over 500. Your crew lacked attention in service and one specific crew member (male) woke me up twice due to the loudness of his voice. Disappointed in the quality for the amount spent."
Pros: "The crew on this flight was absolutely amazing. They were helpful, they were very kind, and very pleasant. Probably the best flight crew I've ever had. Despite originally being annoyed that I wasn't allowed to pick/change my seat, I somehow miraculously got an economy plus seat so I had what felt like a first-class amount of space."
Cons: "Again, the flight was delayed. Despite originally being told that we were trying to get out ahead of storms so we wanted to get going quickly, we ended up boarding and then sitting there for probably an hour and a half. The pilot/copilot were great at letting us know what was going on, but the fact that both the first and second leg of my journey were delayed was excrutiately annoying. Having already been traveling for over 8 hours, the last thing I wanted to do was be even later and extend the flight even longer, obviously. The entertainment also was not available due to some problem in the circuit for the entirety of sitting there waiting to taking off and the first 15 minutes of the trip. Again, the attendants did everything they could and were very attentive, it was just frustrating to not really be sure that entertainment was going to be available for the 9 hour flight you just sat down for. Thereafter the entertainment was great. The food was, again, pretty mediocre compared to other transatlantic flights I've taken. The lasagna was not very good tasting at all. The sandwich they brought near the end of the flight was tasty though. Another plus was full sized cans of juice as opposed to a tiny glass. Honestly once this flight got off the ground it was good. However the combination of the delays, plus my terrible previous flight (which was the one directly operated by Lufthansa, the second flight was farmed out to United) just made the whole journey pretty awful, and probably the worst of my life. On my flight from Munich to Cairo, three weeks ago, Lufthansa left my bag in Munich despite the fact that I had an 8 hour layover - which you'd think would be more than enough to put a bag on a plane. They were very quick about delivering my bag once it arrived, but that previous experience with Lufthansa just served to bring down my opinion of the entire airline. Honesty, I had been told by friends that Lufthansa was a pretty good airline, that didn't show at all. There's a pretty big chance I'll never willingly fly Lufthansa again if there's even a remotely comparable option (which there almost always is)."
Cons: "Flight got cancelled, we did not receive an email or text. We found out when we reached the Heathrow airport. We got booked on another flight, with 6 hour layover. When the flight that got cancelled was a direct flight. Then our luggage was not put on the connecting flight, we got our luggage 24 hours later."
Pros: "Great free movies in first class."
Cons: "The first class crew was not very warm or welcoming. The outgoing flight from IAD set the bar high -- they could've spent less time gossiping and more time remembering my drink order."
