Cons: "Better allergy aware food."
Pros: "Crew was amazing. Pilots were attentive to kids and answered questions. Everyone was very welcoming and helpful."
Cons: "They didn't have some of their food options (and they apologized for that up front), but then ran out of the others by the time they got half way through the plane. That was tough for a five hour flight that went through dinner time."
Cons: "Wonderful"
Pros: "I love ice cream and chocolate"
Cons: "Healthy vegetarian meal choice"
Pros: "Seat was hard, not much foot space"
Cons: "My wife and Iasked for a snack, it was never delivered"
Pros: "Good entertainment options."
Cons: "Only water and coffee available. Flight had been delayed over an hour."

Pros: "Crew was friendly"
Cons: "An hour and a half late, terrible communication about scheduling"

Pros: "Everything went great. Flight left a little late but was fine and only arrived a little late. I like the side wings on head rests really help."
Cons: "Seats are always hard on long flights."
Cons: "I understand Mother Nature causes issues tkayakhat no one can control but when I'm receiving updates from the 3rd party travel app that isn't the airline before receiving any information directly from the airline via the gate agent or Deltas travel app and the gate agent not being able to verify the 3rd party travel app something is wrong."
Pros: "Nothing"
Cons: "Flight was horrible"
Cons: "Delays, delays, delays... first class ticket from BOS to MSP got me a 6 hour delay and a middle seat in econ main cabin at the back of the plane. Delta you suck!"
Pros: "Got to London on-time (early, actually) and safely. The in flight meal was okay. The leg room in comfort plus was great, the mobile app was awesome, and the staff (check-in, gate, cabin and flight deck) were professional and friendly all around."
Cons: "The leg room was great, but as a broad-shouldered guy, the width of the seat was miserable. Unfortunately, the Delta 767 doesn't offer any upgrade for a wider seat beyond Delta One, and my employer won't spring for that. Too bad there isn't a premium economy option. Also, the entertainment unit in the seat next to mine malfunctioned, which you wouldn't think would impact me that much except that because it was "seeing" touches randomly throughout the flight, the screen would turn on, off, brighter, dimmer, play random stuff, and just generally be as annoying as possible to everyone nearby throughout an overnight flight."
Pros: "The flight for getting us therw"
Cons: "No food and no entertainment"
Cons: "Tray table was broken, I was downgraded from Comfort plus to main cabin after a plane swap with no mention by anyone and no compensation. Flight was delayed 45 minutes because a flight attendant was running late and then to top it off, at the end of. The flight the attendants blocked anyone fromaim cabin from leaving until all of first class had departed, even when no one was coming they still Blocked it off. This is a practice I have never seen on delta and haven't seen in aviation in almost 20 years in the US"
Pros: "Plane was on time."
Cons: "My seat assignment was in the last row of the plan when the plane was not full"
Pros: "Leg room and seats are very tight and I'm a small person."
Cons: "Coach class is very crowded."
Pros: "on time, good food, good films enough space to sleep in economy."
Cons: "the stewardess only went up one side of the plane offering eye shades and when i asked for one she seemed really miffed."
Pros: "Delta flights run one time and their fleet seems newer than most with comfortable seating. Having free movies in the seat back ahead of you is a big plus with a good selection of movies. Snacks are good and crew is always friendly and accommodating. We fly almost exclusively with Delta for the aforementioned reasons."
Cons: "Boarding is a hassle no matter the airline with few exceptions. You would think someone could figure and efficient method to get people on the planes. I suppose it could be the public that is the problem. Not a problem with Delta they run a good airline."
Cons: "Delay in leaving from the airport there were issues with Web checkin Crew wasnt able to give me my boarding pass for the connecting flight and kept saying going to the other counter"
Pros: "Nice people. Very helpful."
Cons: "LOST MY BAG IN BOSTON BEFORE EVEN TAKING OFF!!!! Did not make it, and then won't deliver it when it makes it to Kathmandu! This is most distressing."
Pros: "I was going for weekend trip and because of delays I would've been there less than 20 hours. But Delta was terrific in giving me a refund and essy to work with via Twitter. 2 hour phone delay but they called me back to complete refund."
Cons: "Chaos at gates. Changed gate 3 times. No real updates."
Pros: "I was thankful for the early boarding with a lap infant and was very pleased with the options for entertainment on the TV monitor."
Cons: "The main issue I had was that we sat in row 34 and the noise from the engines often made it difficult to hear announcements, even with headphones in. Look into possibly zoning the audio and turning it up a click or two for rows behind the engines."
Pros: "Comfortable flight, ample leg room, and the chairs were pretty plush. Comfort+ is pretty nice"
Cons: "On my first flight they forgot to turn the wifi on. I have unlim data but obviously can't use while in air; no big though."
Cons: "My wife was told she could not board our flight from Boston to Paris because her passport was expired, even though it was not expired. We were told that in Europe passports cannot expire within 3 months of your departure. However, Delta never let us know about this rule until we literally were boarding the plane. How they could not make us aware of this until we were boarding the airplane is unbelievable and unacceptable. This has ruined our vacation which has been in planning for the last six months."
Cons: "We sat on-board the aircraft, at the gate, for almost 2 hours due to a weather delay. During this time, we were not offered refreshments, nor were we offered any type of "compensatory benefit" for our delay (e.g., free Wi-Fi, vouchers good toward a future flight (a $30 voucher per passenger would seem appropriate), additional SkyMiles (3000-5000 SkyMiles would seem appropriate), etc.)."
Cons: "Jet airways sucks"
Pros: "The only flight that was a bit better was from Mumbai to Hyderabad."
Cons: "Almost the entire trip, due to the following reasons: 1. The online check in process didn't work at all. The Delta staff at the Boston airport weren't pleasant and courteous at all. 2. Poor coordination between Delta & Jet Airways - the meal preference was selected before flight at the Jet Airways website but the same didn't get registered properly, even though the website confirmed to me that it was all set. This resulted in appropriate food not being available to the customer on the flight from Boston to Amsterdam. The customer had to literally starve on the flight. 3. The pursers and stewards on the flight from Boston to Amsterdam weren't pleasant and courteous at all. For anything they were asked, their responses ."
Pros: "It only took them 10 minutes to turn things around to make up time for the delay."
Cons: "The seat pockets were not cleaned."
Cons: "Not having a seat assignment until arriving at the gate."
Pros: "Delta service and conford are great."
Cons: "Pay for wifi"
Pros: "you must be kidding me!!! nothing to say good about this fly !!The sad part I'm American Express Delta SkyMiles credit card holder and they couldn't do anything for meThe only good thing we arrive in Mexico"
Cons: "flying to Mexico with. my two boys !!to begin I have to call Delta to put us seat together because the time of the fight had changed!! before we are siting by de middle of the plain when a booked r three seat together !! but than i got a imail confimatin with separete seattle for the kids!!we end up sitting all the way back on the plan!! we end up sitting all the way back on the plane l!! no TVs no windows in the last sits by the only two bathrooms on the plane with two boys that was not fun at all !!The sad part I'm American Express Delta SkyMiles credit card holder and they couldn't do anything for me when I called them"
Pros: "The entertainment system worked well and was able to keep my phone charged."
Cons: "It's very cramped seating. They started boarding by rows but then gave up. Crew are nice."
Pros: "The plane didn't crash."
Cons: "Everything! Flight late, seats to close, worst customer service in the skies!"
Pros: "arrived early"
Pros: "Delta always has a nice professional crew. We were served within a reasonable time and I felt comfortable the whole flight."
Cons: "The pressure is the cabin with really bothering me. I've flown several times and never had the pressure to bother me but it was really hurting my head."

American unexpectedly and without any reason moved my and my wife’s seat so that we were 11 rows from our 7 and 9 year old. I tried to get moved back to our original seats and while they were trying to figure out how to do that, someone bought the exit row and we were stuck. It just seems like being a million miler and and a gold elite don’t mean anything anymore.

Cons: "No pre flight service in first class even though we sat at the gate for an extra 30 minutes."
Cons: "In flight entertainment was broken"
Pros: "Crew was OK"
Cons: "Seat was uncomfortable. There was no power outlet."
Pros: "The crew was great. Flight attendant worked really hard to keep people moving and comfortable and safe. Pilots kept us informed."
Cons: "The plane is a bit older and they need to update their fleet. Boarding process needs to start sooner. Not sure what is ... Took forever for them to board."
Pros: "I didn’t like anything at all"
Cons: "They have to add electronic devices or charge plug on it"
Pros: "Seats were pretty comfortable. We were allowed to deplane down a staircase off the back of the plane. Very cool."
Cons: "N/A"
Cons: "Baggage claim number was wrong. They almost took my bag away"
Cons: "Overall good business class trip."
Cons: "The crew seemed annoyed and not into it."
Pros: "Seat was not comfortable"
Cons: "Need more room"
Cons: "PHX airport baggage claim was a mess. I had to wait 40 min to pick up the luggages."
Cons: "The gate attendant was very hard to understand and so I couldn’t hear what she was saying."
Pros: "It’s not like it used to be. U S based airlines lag behind their European and Asian counterparts"
Cons: "There’s always room for improvement. Too much to list here"
Pros: "The crew was great, efficient and professional."
Cons: "My tv was broken and only played maximum volume."
Pros: "Never even made it on this flight because the first flight was ruined and delayed severely"
Cons: "The fact that my travel plans were entirely derailed and I had to book with another airline"
Cons: "We were told to board quickly so we could leave on time, boarded and sat for more than a half hour. The landing at Monterey was dreadful, hit hard first touchdown and then two more bounces."
Pros: "Coffee"
Cons: "Only snacks available at 5am"
Pros: "Bos to Rome via jfk. Both flights easy in all ways. Grrat first class seat one first flight and quite good bus class on second. New Flagship Lounge a real plus."
Pros: "Quick boarding"
Cons: "Very cold."
Pros: "Flight crew were very apologetic"
Cons: "Missed connecting flight from Miami. Only one flight per day. Had to take a flight to an alternative location, drive for an hour down the coast and take a ferry to my final destination."
Cons: "Entertainment system went down toward the beginning of the flight. The crew seemed irritable, but that was probably because people were upset about the entertainment system. We had to listen to a loooong speech about their credit card. I, personally, don’t like sales pitches over the intercom in the middle of a flight. Had the movies been working, it would’ve paused during the long speech. Not cool at all!"
Cons: "No message to call with passengers with kids to board first or any military personnel boarding first."
Pros: "Generally clean plane with good entertainment system and technology overall. Diabetic meal much better than in the past."
Cons: "Didn't announce meal choices at the start so flight attendant had to repeat herself every. Single. Row. They forgot my diabetic meal on the last part them forgot to include cutlery and it took a long time to sort out but they were otherwise lovely."
Pros: "Nice flight, great leg room, staff was friendly and flight was on time."
Cons: "Not having boarding passes for the entire trip and not checking luggage thru to Charlotte was a hassle."
Pros: "I liked arriving safely, although we were an hour and a half late"
Cons: "American switched pilots last minute, so all passengers sat waiting in our cramped seats for about 15 minutes while pilots got situated in the cockpit. Then it was discovered a preflight mechanical check hadn't been done. So we all sat for another HOUR waiting for the mechanics to arrive and do their work. The flight attendants were unpleasant and rude."
Pros: "Friendly attendants, plenty of coffee. Great service."
Pros: "Due to a strong tailwind we arrived 45 minutes ahead of schedule. Great service with attentive attendants. However the plane was older than me, no real entertainment system or outlets to plug in smart devices."
Cons: "Plane needs to be retired or retrofitted to accommodate smart device charging."
Pros: "The flight to Washington was fine. It was the flight back that I have issues with."
Cons: "My issue with flying back American is that...I didn't. They boarded us on the plane, moved down the tarmac, and then checked to see that we had a brake problem. They took our plane out of service (which I get, I would want brakes before takeoff), but then they never updated us on our status, until I physically went to the counter to ask an hour later. This is when they informed me that the flight was cancelled and we were rebooked on the 9pm flight (Mind you, this is 12:30p and I have a 2 year old with me). Luckily, I was able to book JetBlue and get home earlier (8:00pm)"
Pros: "We had to wait in the airplane upon arrival in La Guardia NY because wheelchair was not ready."
Cons: "The plane was dirty, the window had a leak, the TV was too far away and the sound system to watch the movie was broken. When the plane is in that poor of a condition, it's time to replace it. F."
Pros: "The flight crew was professional, friendly and competent. They served the dinner as early in the flight as possible."
Cons: "This was a plane with central screens along the aisle, and the airline chose to broadcast a sci-fi action movie with almost constant flashing blue light, and violent action scenes. This was first of all a movie that many people, including me, would never choose to watch, but since it was on the aisle screens there was no getting away from it. It was also unsuitable for children, even without sound. But mainly, I object to the showing of any film in that situation - only aisle screens available, and on a night flight where most of the passengers are trying to sleep. I was awakened several times by the flashing lights. Other things: one of the bathrooms was not very clean, and the plane felt like the usual cattlecar, with just 3 seats on each side of the aisle, which is unusual and unpleasant for a transatlantic flight."
Cons: "Almost did not make it on the dieses flight because totally crowded at security check point."
Pros: "Was on time"
Pros: "We arrived safe."
Cons: "The plane had been on the ground for 6 hours prior boarding time, yet we leave until 1 hour late. Waited for the food to be loaded and then waited for paperwork to be signed. Really?"
Pros: "Old school seat. No foot rest. Small plane to go coast to coast."
Cons: "UI on the entertainment system was horrible."
Pros: "The flight was on time and the crew are nice with the people"
Cons: "Too crowded not able to take my other luggage on board."
Pros: "The in-flight entertainment interface was well-designed. The aircraft tracker is the best, the media selections were plentiful. Having the usb and headphone plugs next to the monitor is the best. Better than Virgin for sure. But strangely, you couldn't order from the food and drinks menu like you can from Virgin so it was just a video version of the menu card. Food was good."
Cons: "Someone destroyed a lavatory so we were short one for the flight and caused a 30 minute delay before take-off. The usual spiral happened: pilot flew into bad turbulence to make up time. No biggie."
Cons: "Jetway should not be backed up all the way to the counter. Stop calling so many groups for boarding without knowing that no one is actually getting onboard. Force subsequent groups to step aside until called."
Cons: "There was no one at the gate to keep us updated about the flight delay"
Pros: "Good experience all around."
Cons: "15 minutes late. No big deal though"
Pros: "the flight was on time coming and going"
Cons: "Being stuck in a high dollar city for an additional night when i should have made it to the lower intermediary city and flown standby the next day."
Pros: "On time"
Pros: "Great entertainment system."
Cons: "Over an hour late."
Pros: "Crew was nice including those helping with boarding."
Cons: "Difficult to recline chair. Limited snack options. Landing was a bit rough."
Pros: "The cookies were good"
Cons: "The gangplank was broken. It took so long for them to ascertain the situation, move the broken gangplank away, move the plane from gate B15 to B16, load passengers & luggage and take off, that I missed my connection in LaGuardia. I had to get a standby flight & thankfully got on. Why wasn't that equipment checked out long before it was used?"
Pros: "Plane wasn't full"
Cons: "We booked on British Air, but got American Airlines. Something I didn't realize. I don't like Amercan Airlines! No internet, no tv. Only overhead tv too far away to see from my seat and no choices Old plane"
Pros: "I made it to NY somehow"
Cons: "Everything. I have 2 roller bags I carry on to every flight I have ever taken and they charged me $25 per bag to check because it was a "snug" fit into their dimension box. Also gave no snacks and only half can refreshments, no entertainment."
Pros: "We didn’t crash."
Cons: "First class seat was uncomfortable and had very little padding. Meal service was not good. No drinks offered."
Cons: "It was a mess from start to finish. Ridiculous lines. Ridiculous covid rules. They have us all shoulder to shoulder in tiny waiting areas then suddenly we get on line to board and have to stand six feet apart and then on the plane we are squashed all together anyway. It’s all so stupid. Not having the ability to get a boarding pass from the online app or printed made me have to wait in a line 300 people long to access the kiosk and then half of them were down. Then another line maybe 500 people long just to be allowed up the escalator to where there is another line to go through exuding checks. Nuts!!! My flight was an hour and I spent three hours online getting to it!!!"
Pros: "The crew was great as was the check in crew."
Cons: "The comfort of the seat and leg space."
Cons: "Less people because of COVID"
Pros: "Same"
Cons: "Hire better competent people"
Pros: "The crew and the entertainment were excellent."
Cons: "The seating area is very tight and the aisles were extremely narrow."
Cons: "Serving something substantial to eat would be nice."
Pros: "The flight was smooth and the crew was nice."
Cons: "Everything was good."
Pros: "The staff at the boarding gate and the flight crew were friendly and professional."
Cons: "The United gates at Logan airport were quite horrible. Poor signage, limited bathrooms, and all the dining options were quite expensive."
Pros: "Cost"
Cons: "Aircon too cool"
Cons: "Reliability"
Pros: "Water and snacks offered when flight was delayed over an hour! Crew."
Cons: "Flight delayed over an hour."
Pros: "Salmon and rice."
Cons: "Tvs not working and staff pretending as if they would fix it but actually the problem been going for a while with that airplane. The pizza should not only be a vegetarian one ."
Pros: "Good. Seating. Not too crowded"
Cons: "Na"
Pros: "Very comfortable flight"
Pros: "The flight went very smoothly from start to finish"
Cons: "Our airplane was supposed to fly 9am but our company changed our plane for 5am"
Pros: "We had issues in that there was no crew! But the United people were great and got us on another flight going to Newark and we were still able to make our connection to Aruba!"
Pros: "The flight attendants were so nice, and although our flight was delayed and hour and fifteen minutes and our layover was an hour and fifteen minutes, we were able to make our connection! Since our connection to Portland in Denver was the last flight of the night, they were able to hold it for us. This was wonderful because there weren’t many flights out that weren’t booked solid for the next day. The attendants on this flight were great about updating us with information for the connections and telling us when we would land in Denver."
Cons: "The plane was delayed over an hour for cleaning. It was frustrating to say the least."
Pros: "Staff was friendly"
Cons: "United has a system glitch and we were delayed. I got in around 1 am instead of 11 pm. I decide to order a glass of wine and since they don’t give receipts. I found out i was charged for 2 glasses instead of one. To top it off the co-worker i was traveling with didn’t get charged due to the inconvenience and delay. i travel a lot with United (higher status than him) and would have liked that offer (and not get charged one i didn’t order) being a mileage plus and credit card holder. I did go on line and ask for a credit and they did make it right and give me a credit."
Pros: "Easy check in. Good flight. Good food."
Cons: "Had anightmare will complain to united diect"
Pros: "They staff was friendly and they boarded efficiently."
Cons: "The worst part of the flight was the fact that they have redesigned their planes. They have put the seats even closer together and their new seats are horribly uncomfortable. The seats are made out of a hard molded plastic. There is no give and they don’t form to you back at all. Their comfort level I would rank at a zero! I had thought they may not be bad for a domestic flight as mine was international, however, I also had them for a domestic and they were equally uncomfortable. I will be checking off of United on my next flight as I can not sit in a seat this uncomfortable ever again! Try again United!!! #UnitedSeatsUncomfortable, #HorridSeats,"
Pros: "I was separated from my 4 year old and 7 year old children as well as our husband. We bought our tickets together but we're out on 4 different rows. I asked flight attendant for help and she was rude. She talked to my husband who was further in the back and came back and told everyone it was ok for my kids to not be with their parents because my husband said it was ok. It was not ok, it was awful. After I started crying someone finally traded spots. But I didn't like that my husband's wishes over Road mine, it was misogynistic and she was a woman, a very condescending women."
Cons: "That our family was separated. That the female flight attendant talked down to me in a misogynistic way"
Pros: "Landing in Dulles"
Cons: "Poor boarding - had to walk steps with luggage, board a bus and wait for 10 mins in hot weather, then had to walk steps to plane with luggage. Plane - no place for cabin baggage and people had stuffed inefficiently their bags; crew did not seem to care Crew - did not care, pointing fingers at people like they do not know English, no sense of pride or commitment in their job; they might as well thrown food at us Food - bad, lucky we were hungry Entertainment screen - not working well Flight was smooth I do not know why Lufthansa partners with United Airlines."
Cons: "The food was terrible."
Cons: "Flight was delay for more than 45 minutes"
Pros: "The plane left on time and smooth transition on and off the plane."
Cons: "N/A"
Pros: "The crew were excellent and receptive to needs on the flight."
Cons: "Baggage Claim was a nightmare. I did not receive a baggage ticket when I checked my bag in London. Part of that is my fault. I should have made sure I had one. It took an extra long time to get my bag. Everyone else had left the area from my flight and I approached the counter. The attendant at the counter was rude. She said she couldn't help me unless I had the baggage claim ticket. Which I get that, but it all comes down to how she said it to me. She went over to the carousel and said that my flights bags were still going around and at that time I saw my bag. I said there it is to her and she responds, well you can go get it yourself then. Just completely rude. It all came down to how she responded to me. I was freaking out at the prospect of my bag being lost and she responded as clipped and uncompassionately as possible."
Pros: "The movies were good - glad it was free and nice selection"
Cons: "US Pre-clearance in Dublin was ridiculous. I don't know what else to say about it. They were even holding us going down the escalator to the actual screening part. It was just one crazy queue to another. Will definitely make me think about ever going through Dublin again."
Pros: "The cabin crew themselves were great. The pilots offered my child to go see the cabin and everyone on the actual plane was great."
Cons: "The United employees at check in kiosk were very unorganized and unhelpful. I was traveling internationally with a small child and had two pieces of luggage to check in. Normally you just go to the counter once and they do everything including taking your luggage once they weigh it. Instead, I had to go to the self check in kiosk, then back to the counter to weigh my luggage, take off the one luggage from the scale, weigh the second one, then go back to the self check in kiosk, then was told to take off the second luggage as well, then finally went to a second counter where the lady handwritten my luggage tags and then was told to take both pieces of luggage and put them somewhere else altogether with specific directions on where to put them. This is something normally handled by the actual employees. Also, the check in dude yelled at my kid for putting in his name into the check in kiosk while we were waiting on the check in dude to do all those unorganized activities. He claimed it would break the software if my kid were to enter his name. I have told him that no, the software will not break if my child enters in his name."
Pros: "Typical intercontinental flight in coach. Plenty of movies to watch, bin space and comfortable enough seats."
Cons: "I have a severe food allergy and despite requesting and confirming my special meal multiple times I was only offered a banana for the entire trip."
Cons: "Rude crew, departed three hours late, and not permitted to bring carry-on luggage. Awful."
Pros: "Seats."
Cons: "Sat in the middle of two people who took up part of my seat too."
Pros: "Flash for mac did not install"
Cons: "I felt like I was on my way to my death"
Cons: "Forced to check carryon bags because they said the overhead bins were full. Upon boarding found many overhead bins empty and people who boarded after us were able to bring carryon with them."
Pros: "Willing to drive to Charlottesville. Difficulty finding one way rental"
Cons: "Above"
Pros: "The people were very nice! The entertainment although not easy to access was free. snacks were meh but ok. They did what they could to make us comfortable after flight was delayed 2.5 hours."
Cons: "The flight was delayed for 2.5 hours was out of the control of the crew. They did what they could. But the plane was cramped. Not enough space. Everyone was cramped. We missed our connecting flight they put us up in a hotel and booked alternate flights. We had to stand out in the cold waiting for a shuttle to take us to the hotel. The hotel staff said more than once they were not prepared for all of us and getting us from airport to hotel and in rooms was almost another 2 hours. That gave us 3.5 hours to sleep before we started in the next journey. Of 4 hours from take off to landing in our home city. I had to pay for my baggage to go onto another airline."
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: "Very windy during flight, kudos to pilot and crew"
Pros: "Kelly is an exemplary employee at the United counter at Logan. She showed compassion and caring after the passing of my brother and changing my ticket . Kudos to her!"
Pros: "Everything"
Cons: "NA"
Pros: "Found what was expected from the flight. Hats up to the take off that happened on time in a busy airport."
Cons: "Aircraft is tiny and seats are narrow."
Pros: "They held the plane due to delays in customs"
Pros: "Everything except the wifi not working"
Cons: "The wifi not working"
Pros: "Aircraft with old decoration. Could not see a single smile from the crew."
Pros: "Comfortable and enjoyable flight, efficient crew without delays."
Cons: "Poor food - even going for the safe pasta option. Very disappointing & not enjoyable."
Pros: "Once I was on the flight it was fine except for the food which was decent"
Cons: "On my outbound flight from IAD to BRU my flight was delayed 3.5 hours because the "plane was late to arrive". Seems like this happens a lot on United flights. The staff at the gate of Dulles airport were extremely rude and difficult to deal with, which made it frustrating to try and figure out my connection situation. I missed my connection from Brussels to Paris and had to buy a train ticket for which I was not reimbursed by United. Then, on the way back from Paris, my flight was delayed 2.5 hours for the same reason. At least this time I had a direct flight. This entire experience makes me think twice about flying United again. I live in DC and it would be just as (in)convenient for me to go to BWI instead of Dulles for international flights, where there seems to be more options outside of flying United."
Cons: "As a military spouse I was not allowed to check a bag free so I paid the fee. When I boarded I noticed many passengers bringing bags on that we're as big as the one I just paid for. They either checked for free or brought it on and managed to shove it in sideways taking up space that others needed. Some people brought three bags on!!! As a military spouse I feel cheated to have had to pay when others checked in for free at the gate. Not cool United, either let the spouse check in for free or make everyone abide by the so-called rules of one carry on that actually fits into that metal baggage guide. I would like a refund of 50.00 for the baggage fees I paid for this trip."
Pros: "Curbside checkin and luggage check"
Cons: "Nothing"
