2hours delayed and didn't give notification right away 🤷‍♀️. I even lost my food to rush to go to the airport. Paid $60 for seafood plate ending just leave it almost halfway on my way to the airport find out the flight was delayed. I wish they have more accurate policy to let passengers knows for any problems about the flight as soon or as early they can

2hours delayed and didn't give notification right away 🤷‍♀️. I even lost my food to rush to go to the airport. Paid $60 for seafood plate ending just leave it almost halfway on my way to the airport find out the flight was delayed. I wish they have more accurate policy to let passengers knows for any problems about the flight as soon or as early they can

Pros: "Plenty of room."
Cons: "Heavier snacks."
Pros: "I never boarding this flight."
Cons: "Better communication skills."
Pros: "The crew was very attentive and had great personality. They anticipated any needs we had."
Cons: "On board entertainment was inop, making for a long (4) hours flight."
Cons: "Flight was delayed almost 3 hrs. Ran out of food right before my row. I upgraded my seat but feel I got the short end of the stick."
Pros: "Quickly moving through the airport."
Cons: "Take out old planes. It was really run down."
Pros: "The plane was nice"
Cons: "I’m still sitting in Minneapolis so I would have liked to be at my destination. And I had to pay for the overnight accommodations."
Pros: "Crew was friendly."
Cons: "Wish the seat was more comfortable. Landing was jittery and bumpy."
Cons: "4 hour delay"
Cons: "Delayed"
Cons: "My 'window' seat had no window! Feeling was claustrophobic"
Pros: "The service by delta employees for this leg of my journey was beyond great. The leg room was above average."
Cons: "Leg room. Never can have enough leg room."
Pros: "Great flight"
Pros: "Super comfortable seats. Lots of movie options."
Cons: "Food was not very good"
Pros: "Flight was smooth, arrived early..crew was prompt and courteous."
Cons: "After a delay of about an hour on a very full flight the gate agent asked for volunteers to check their rollaboard suitcases. The gate agents then allowed those who checked their rollaboards to board before Zone 1,which was fine. However, a bunch of people without gate check stickers on the rollaboards were also allowed to board before Zone 1, which was aggravating. There was a long delay on the tarmac, during which we had to pull back to the gate or to a maintenance area before we finally took off. When we arrived in Vegas there was no gate for us to pull into, which led to another long delay of an already long and delayed flight."
Cons: "at last minute itinerary was changed.. instead of routing through Brisbane, was now routed through Sydney. Flight from Sydney to LAX was delayed by 4 hours, then missed flight LAX to LAS... overall long delayed arrival. Checked the route through Brisbane, and those flights we're all there, departed and landed all on-time... so wondering what the reason was for the change of the itinerary without a cause (no cancel or delayed flights through Brisbane)"
Pros: "overall flight great,pleasant trip, courtious well informed crew"
Cons: "In flight entertainment screen down"
Pros: "crew was nice and pilot was informative."
Cons: "1. flight was delayed twice, which meant my arrive was delayed in Cincinnati. 2. boarding was a nightmare. After 2 delays, I was crammed into zone 4. I dont fly as often, the seats space seems to be getting smaller. 5. I sat next an overweight person. I didn't like my personal space violated. 6. The flight offer movies, I slept. Yet kept getting elbowed by this overweight neighbor. 7. I am a single, independent person. I prefer to sit near the front. First on and settled and 1st off and gone!"
Pros: "Fly attenden alwas with a beautiful smile"
Pros: "The flight crew was friendly and personable. Beverage service was consistent and efficient. Entertainment and free WiFi messaging were great perks."
Cons: "The positives don’t even come close to offsetting the misery of Delta’s seats. I honestly don’t remember the last time I was so cramped and uncomfortable. I’m not an abnormally large man - 6 feet 200 lbs - and there was no room for my legs or my shoulders in an “upgraded economy” seat. I fly weekly for work on another major airline, and only took this one in a crunch. But I am quite certain this was my last Delta flight and I’ll be advising others similarly. The service and entertainment aren’t sufficient to mask an awful seat configuration."
Pros: "Service was great. Regular drinks and snacks."
Pros: "Great and friendly crew"
Cons: "baggage rules, check in with baggage, change fee for flight when it was not customers issue that caused the 5 min delay! Unable to reach reservation desk on line or via phone (neither was the gate agent)"
Cons: "Seeing as I’m still waiting for my flight, more than five hours later I am not inclined to rank it highly. This airport is an embarrassment and I will try my best to never fly Delta again. Weather is no excuse for this."
Pros: "comfortable seats"
Cons: "delay delay delay"
Pros: "Special staff great pilots snacks free movies safety"
Cons: "Everything was great"
Pros: "Quick friendly service from crew and captain."
Cons: "First class seat was broken was reclined and super uncomfortable the whole flight the plane was super outdated and old."
Pros: "Good selection of movies/shows."
Cons: "Flight was delayed half an hour due to “medical emergency”. Guy passed out as we were about to take off so we turned back to the gate and sat on the plane for over 30 mins while we waited for medical personnel to check the guy out. Then had to wait another 15 mins for the fuel truck to refill us because we had burnt so much sitting there. I understand that we had to turn back due to his condition but why was he not removed from the plane and put on a later flight when he felt better instead of making all of us late? You would think after all this the crew would be kind and appreciate our patience but 2 of the flight attendants were the exact opposite of that. Both of them were very short with people and the one kept rolling her eyes at people as they were handing out drinks. The only thing I would give 5 stars is the tv entertainment. My seat wouldn’t even recline for me to enjoy though."
Pros: "It was whatever"
Cons: "Delayed two hours"
Pros: "Got to my placs"
Cons: "Lol put the two fattest people next to each other"
Pros: "Flight attendants and cookies. That's it."
Cons: "We left DC late because of Delta's inefficient boarding process. We landed in Atlanta late. Our flight to Sioux Falls left early, without us. My pregnant wife and I made it to the gate 4 minutes before the scheduled departure and they told us the plane was already gone and there was no way for us to get on the plane. Our bags did make it to Sioux Falls, so my wife didn't have her prenatal vitamins, , we had no clean clothes and we were forced to spend the night in Atlanta. The saddest part of yet another terrible experience with Delta was that they offered us a "discounted" room at a terrible Howard Johnson for $72. I looked online and the same hotel was $65 to book on Kayak. So basically Delta was trying to scam us after they screwed us. Thanks Delta! Instead we paid $200+ to stay at an airport hotel. Every time I fly Delta I regret it, yet occasionally I get forced to take their awful airline to get somewhere I need to go. It never fails to add another bad Delta experience to my long list of failings from this SAD!!! airline."
Cons: "I liked it all"
Cons: "There delay"
Cons: "I froze on the way to Las Vegas and there weren't enough blankets."
Cons: "Female flight attendants were rude and acted like the passengers were a bother. Tried to move to an emergency row after the doors closed, which was empty and the flight attendant refused stating we had to pay extra. NOT HAPPY"
Pros: "The process was very quick and easy, from after security the process was smooth and fast."
Cons: "The gate that I was assigned to was a little overcrowded but I believe it could be because of the construction that is happening in the area. Also the security process was a little long."
Pros: "The crews were very friendly and everything went as planned. It was a nice flight."
Cons: "I didnt like that my flight was canceled and rebooked for no reason. This created me big problem in Athens that they couldnt find my ticket in delta. Also I didnt like that i had to stand and wait for 3 hours in the line because my flight was canceled but no one could let us know if there gonna be any flights within the day. I slept in the airport because i couldnt find a hotel to spend the night close to the airport. They were all full and i had no time to find one since I was waiting there for 3 hours with no informational. I slept on the floor and delta didnt even offer us a blanket. That was my worst trip ever."
Pros: "Everything was great"
Cons: "Nothing everything was fine"
Cons: "Undersized overhead bins so ALL carry-on rollerbags had to be checked."
Pros: "Nothing"
Cons: "Two out of three flights were delayed, customers service of the flight operated by Delta airlines is a nightmare and on top of it 2hours and 40min delayed. No drinks, no snacks, nothing."
Pros: "We were traveling with a group of 8, only 3 of us had assigned seats when were arrived and the others were on standby. We asked the attendant at the gate desk if there was any chance that the rest of us on standby could be seated together... HE UPGRADED OUR WHOLE GROUP TO COMFORT and allowed us to all sit with each other. Greatest flight experience I've had and such great staff with Delta. Will fly Delta going forward whenever I have a a chance (flew Southwest the rest of our trip - service, cleanliness, friendliness didn't compare)."
Pros: "Ok"
Cons: "Was ok"
Pros: "We arrived in Las Vegas"
Cons: "Even in first class, it appeared to me that the legroom has been decreased."
Pros: "Good entertainment with games for kids, movies etc."
Cons: "No meals (5+ of flying), need to buy earphones, no place for hand lauggudge"
Pros: "Nothing"
Cons: "Being scammed by the Chinese, China Southern"
Pros: "The flight attendants were nice and polite!"
Cons: "My cell phone needed a charge but I did not realize that at my feet was a place to plug in a USB cable! This is great to have, when this is available it would be great to let the passengers know!"
Pros: "A good crew working to do their best"
Cons: "What else? Just too little space..."

Pleasant flight. Everyone was on the same page. Efficient boarding and nice checkin experience. Bags were delivered to baggage claim quickly in Las Vegas.

Pros: "Comfortable seats"
Cons: "It was all good"
Cons: "No gate when we landed."
Cons: "My tray table was dirty. It had crumbs on it. The flight was on time which was awesome."
Cons: "The seats are extremely restrictive and in a aisle seat I had the gentleman sitting next to me with thighs touching and attendants brushing by me as I squished to left to avoid contact with him. Entertainment screen between center seat and window seat so I just didn't even try to look at it and mostly just leaned forward to have a little space. Also another inch or 2 was taken by person in front of me putting their seat back. With such restrictive space why is this even possible??? Flying has become ridiculous and I try not to as much as I can."
Cons: "Unexplained 3 hour delay. They couldn't be bothered to automatically rebook me to an earlier flight (other airlines do this). They also couldn't put me on standby over the phone?! I had to wait for someone to arrive at the gate and then get on standby."
Pros: "Good flight"
Cons: "Delays"
Cons: "We landed early but the plane was late 50 minutes into gate. Plane went pst our gate twice, just driving around the terminal."
Pros: "Crew and seats super comfy"
Cons: "TV in the seat"
Cons: "I'm expecting more from AA. We were delayed for 2.5 hr since we didn't have a pilot !!!!!"

Cons: "Delayed for an hour due to a log book issue."
Pros: "Nothing."
Cons: "Staff, room, boarding process, flight schedule and more!"
Pros: "Overall clean and comfortable"
Cons: "A coffee or a snack"
Pros: "On time"
Cons: "Tiny seats, no snack or napkin with the drink. Noise in back."
Pros: "Everything except cabin comfort was fine"
Cons: "Very hot on the whole flight"
Pros: "Basic flight. Super uncomfortable seats. Older plane. Cramped. Pilot was great. Flight smooth."
Cons: "Got there safe!"
Pros: "We took off and landed safely."
Cons: "Felt very low budget and cramped."
Pros: "At Least the Staff was keeping us updated."
Cons: "No good-faith gesture was offered for the long delay. My associate and I completely missed an important dinner meeting with the rest of our team! Our team takes this trip each year and we have always drove. It' short and I then have transportation when I arrive. This year we decided to fly because it's even easier. This particular flight from Phoenix to Vegas took us longer then if we were to drive and I then spent more in RideShare. I won't be doing it again next year."
Pros: "It was fine. Just not anything great."
Cons: "Many groups were not seated together. at the airport I asked if my husband and I could be put together . One worker seemed interested in helping, but another rudely butted in and said there "were no seats together, the flight was full." Come to find out the flight was not full, there were whole rows not full. The groups near our seats rearranged ourselves so we could be by our family members, so it worked out. No thanks to the person at the terminal. Really long walk from the gate to the plane. No food on a cross country flight. Only a few cups of water/soda and a cookie. which unfortunately is typical now days. The lights were off the whole trip. The captain kept turning on the seat belt sign for the turbulence. Which there was a lot of. But then he would announce for everyone to go back to their seats. It wasn't huge bumps, just a little rough. and it woke everyone up by announcing it multiple times."
Pros: "Not much"
Cons: "Passengers brought hot food on board at Dallas. McDonalds and KFC odours were overwhelming for first 30 minutes."
Cons: "The male flight attendant was incredibly rude, kept hitting my arms with his body with zero apologies. No manners when taking food and drink orders. Did not seem like he liked his job and in a customer service atmosphere this was extremely disappointing."
Cons: "When I️ went to the gate to Ben seated they said there was overbooking, but 10 min before departure they allowed me to fly"
Pros: "Oh the crew was very pretty. They spent more time on themselves their hair their make up and on their phones than they did the entire first class. Check our flights and miles. We fly AA ALOT for ourselves and other. WCB4350 Shipman. We don’t complain ever. But when you spend what we do and only just get your first drink with your dinner in the air is utterly ridiculous. Never got a clean up or a second drink. Had to interrupt the glam squad from their phones and make up bringing them our dirty glasses and trash asking for a second drink. Not impressed with this crew at all! Normally AA IS TOP KNOTCH. So it sets the standard that we’ve been accustomed to however complete and total letdown on this flight"
Pros: "Boarding and flight was on time."
Cons: "Nothing"
Pros: "Plane was new and entertainment was free. Great service too."
Cons: "American has improved a lot"
Pros: "Customer service people were nice."
Cons: "American Airlines broke my carry on luggage handle and was told that I couldn’t claim it even though I was told that I had to check it in. Airplane was cramped, felt really uncomfortable"
Pros: "Seats quite comfortable. Crew ok."
Cons: "Pitiful food offering and no entertainment at all when on previous 1.5 hour AA flight choice of movies."
Pros: "The crew for the most part was nice."
Cons: "It just wasn't a comfortable flight and then a extremely bumpy ride all the way from LA to NYC."
Pros: "Boarding process and flight crew were just fine - nothing excellent, just average. The plane was an older model, nothing special. We arrived 10 minutes early but then had to wait 20 minutes for a gate."
Cons: "They had no alcohol and no entertainment on a Transcontinental flight from IAD to LAX. Also once we landed we had to wait 20 for a gate assignment."
Cons: "Boarding complete chaos. Looked like Bangladesh. Very unorganized. No airline has ever explained why they do not board from the window seat out. Would reduce much confusion. Too much to handle."
Pros: "entertainment displays on the back of every seat headrest. Nice room on Main Cabin Xtra, even with someone in the middle seat."
Cons: "1 of the flight attendants was pushy(older caucasian lady)"
Pros: "Good preferred seat."
Pros: "On time."
Cons: "The door team was all over the place creating a chaos at the time for boarding the plain. I've notice several people in front of me were complaining due to the boarding dynamics. (Not smooth boarding)"
Pros: "Boarding the plane from the back first saved longer queues. Unfortunately people cheat and the boarding officers don't send them back to the right queue. Toilets were clean. Staff excellent. I was glad all my flights were stuffed to the gunnels. Presumably that is best for the environment rather than lots of planes with fewer passengers in each."
Cons: "Passport control with new computer ID checks was fast. Baggage was slow coming. I booked through Netflights and they didn't book me a good seat. If I could have changed it myself they should have told me. On the way to Tampa on 3rd March I couldn't check in within 24 hours and had to wait half an hour while they changed our plane. BA used to do short science programmes which I loved. Shame these have finished."
Pros: "Nothing"
Cons: "Seat 17F is very short on leg room for a 6 foot man. Flight attendants didn't care and rough landing; pilot needs more practice."
Pros: "Friendly, helpful flight attendants. Flight left and arrived on time, despite being completely full (asking for volunteers to bump). Offered to gate-check our carry-on bags for free to alleviate crowding of overhead bins was fine for us since we already had checked baggage."
Cons: "If you don't pay for the premium seats, the legroom is pretty tight. I'm only 5'8" and I felt it -- if you're 6'+ you better pay for it. This aircraft had screens, but not individual ones so you're stuck watching whatever sitcom replay they pick, although there is a moderate selection of other music. I've been on a newer aircraft with the in-seat power and interactive screens so I know how good it can be, so this was a little disappointing."
Cons: "Being led to pay to select seats on flight that was only 50% full"
Pros: "Plane was clean; staff professional; no issues."
Pros: "I did like sitting on the left side of the plane. There's a little more room. I feel it's horrible how the airline charges so much and cram so many seats in one air craft. Making it a miserable flight."
Cons: "See above"
Cons: "no food"
Pros: "None at all. Very poor customer service."
Cons: "Very poor customer service. Flight attendant name Daryl H. Colored male , declined to help me put my carry on luggage onto the over head bin. Instead he scolded me not to bring carry on luggage if I can't put it in. The bin wax too high for me . I'm 4'10 inc tall and unable to reach the over head bin. And Daryl H, was sitting on my paid chair. A nice passenger offer his help and put the carry on to the bin. I will not book this airline again."
Pros: "The crew was very helpful and kind."
Cons: "Our flight was delayed over an hour and we had a connecting flight to Vegas that we were worried we were going to miss."
Pros: "It was last minute booking, I was balky for the price and the overall experience was comfortable."
Cons: "They forgot to get my coffee but it's nothing major plus we were about to land in 30 mins or so"
Cons: "Our flight was delayed and then cancelled. We were given new flights the next day 8/20/16 and that was delayed for a few more hours. We wasted a day and a half at the airport and our hotel for the first night could not be refunded."
Pros: "Nothing"
Cons: "We sat on the runway for more than an hour."
Cons: "Once again the flight was delayed. Last time American Lost my connection TWice! It took me two days to reach my destination. I was cramped in a middle seat and one of the flight attendants was rude."
Pros: "On time flights."
Cons: "Middle seat."
Cons: "The flight was cancelled. Then we all were told to re-ticket at customer service. Waited on the line for 2 hours to get a stand by ticket for the next flight. Luckily I was the second from the last that got the seat, or else I would have to wait for the next flight which would take even longer than just drive to Vegas myself. I asked customer service to accommodate me with some food coupon since I had to wait for the next flights...they said they don't have that kind of accommodation, really?!!!"
Pros: "Crew and plane ride."
Cons: "The seats hurt us."
Cons: "If you dont have TSA precheck....get it...lifesaver"
Cons: "The plane was filthy. It made me sick thinking that im stuck on this plane that they never clean..in the peak of sick season."
Pros: "Crew was nice"
Cons: "Leg room"
Pros: "Not much after sitting in the airport for two extra hours on both flights"
Cons: "They could have boarded flights on time or at least explained why the flight had been delayed."
Pros: "Crew was nice and efficient."
Cons: "Check in counter needed more help-line very long"
Cons: "They charge $50 for a carry on bag!!!"
Pros: "Boarding was fast. We arrived early."
Cons: "It was too cold & they kept turning on the lights (it was a late night flight)."
Pros: "Nothing"
Cons: "Flight attendants talked loudly the whole flight. Very uncomfortable"
Pros: "The crew was very nice."
Cons: "The AC was broken - only the front half of the plane was getting it. The back half was very hot."
Pros: "Comfort nice cool cabin on boarding"
Cons: "No complaints with airline but flight was a little ruff on approach made me a little nauseous."
Pros: "We had about a 45 minute weather delay but those things can't be helped. The Captain kept us informed and he flew like superman getting us through all that crazy wind coming into Las Vegas. The plane was new and clean, the crew was great. Love that wide aisle...it eliminates that sardine feeling!!"
Pros: "Definitely the price. Fairly quick boarding process, just a little congested. Decent priced drinks."
Cons: "Not the most comfortable seats, but there was no one next to me, so it was okay."
Pros: "The crew was amazing"
Pros: "The gate agent was amazing and super helpful."
Cons: "Seats are tight and not very comfortable."
Pros: "Nothing"
Cons: "Still in Reno. Aircraft broke down"
Pros: "LEFT EARLY ARRIVED EARLY PERFECT"
Pros: "The staff was friendly"
Cons: "The flight was delayed multiple times, the directions on having boarding passes on the app or printed prior were not given so found that our last minute to avoid paying the front desk clerk $5.00. The flight landed 5 hours later than scheduled which is completely unacceptable."
Pros: "Nothing, honestly. Constantly delayed, cheap airline with forced fees, only one I could take and I can’t believe you exist. You have horrible customer service"
Cons: "I will never fly you again. Sure you don’t care."
Cons: "Delays!!"
Cons: "So many charges at every step. $5 for boarding passes?"
Cons: "I am so angry booking with them. I booked the flight and then thought, ok I will add a rental car. It said clearly that the rental Car could be canceled up until 24 hours before the flight. Well, 2 weeks before the flight, my friend said, don’t get a rental car, I will have my car. So I cancelled and only then did I find out that once I booked it through their site I could not get a refund for the car and I could only get a voucher for use on one of their flights! And only after they take out any fees and costs that was accrued! So angry!"
Cons: "Flight was very late. Have to pay $45 for a carry-on bag. Seats were uncomfortable and have to pay for all snacks and drinks including water."
Pros: "It was easy to book. And they helped me make changes to my flight schedule without charging me"
Cons: "Everything else is charged... from the in service beverage cart, to your boarding pass. Your baggage. Everything you have to pay for. So just be prepared for that."
Pros: "Quick boarding with no fuss."
Cons: "The planes could be a lot cleaner."
Pros: "Better than on time Smooth sailing through south bend airport!"
Cons: "Just have to remember thrift airline No seat going back"
Cons: "baggage staff was super rude. She told me I am the last passenger on the plane which wasn't true. She made me pay $50 because of little overweight. I could easily redistribute the weight among my bags if she gave me little chance. I was a single mom with two kids (3 months and 3 years old) had to pay a fine which I can't afford. Thanks for giving me the chance to express my feelings."
Pros: "Friendly staff"
Cons: "Last minute delay due to a plane malfunction. Was told very last minute. Seemed like there were no quick resolutions in play. Had to wait over three hours to fly out, doesnt that entail compensation by law?"
Pros: "Fare and friendly staff."
Cons: "No wi-fi."
Cons: "Our engine seats at the rear of the plane were of course a little noisy at first. We got these seats on both our flights. Hoped that at least one-way we would have managed seats with a window."
Pros: "Love the ticket price, but charging $44 for a carry-on? C'mon man! Added charges that were worth it? Priority boarding: $15, Exit row seating: $25 Also be advised that all food & drink is for purchase and must be purchased with debit or credit card - absolutely no cash."
Pros: "On the way there and back the staff was friendly, the flight was smooth and and overall everything was just great. This was my first time flying with Allegiant and I will definitely do it again."
Pros: "I arrived safely Tommy Destination"
Cons: "It was so hot boarding and unloading. There was no air. Staff was curt and not very friendly as of assistance."
Cons: "Old plane with fixed seats with very limited leg room which were not comfortable- broken window shades, scratched windows, & rattles everywhere made for a long flight. Crew was ok, I would fly again if the price was enough of a savings"
Cons: "Allegiant 468 7/27 4 1/2 hour delay on flight 569 on 7/27 and not a single person on the ground or plane even said sorry. Allegiant also failed to update the revised departure time. Allegiant posted an initial delay of 30 minunutes but then, when there was a further 2 hour delay due to a problem with the plane in Vegas Allegiant didn't update the time. (G4 568 was showing a two hour delay, with a 1010 arrival into STS but Allegiant never updated the departure time for 569 to reflect the additional two hour delay.) It wasn't until I called that it got updated and when I called I had to point out that the airplane hadn't even left Vegas and Allegiant was still showing an 8:50 departure time. It also took the reservation agent over 20 minutes to get any information about what was going on. Lastly each and every time I call I was on hold for a minimum of 20 minutes before being able to speak to a person"
Pros: "Comfort and speed of the flight. Attentive staff!"
Cons: "Need one craft beer"
Pros: "Their flights are always delayed. They have some pretty old flights and they always get broke before the take off and they have to do some maintenance before take off. Not going to fly again with them."
Cons: "Entire flight experience."
Pros: "Cheap"
Cons: "Literally had to pay for every little thing that is usually included in other airline tickets."
Cons: "The flight got cancelled - trip had to be completely rearranged."
Pros: "The price of the flight was cheap, but i know why. You ended up paying for your carry on luggage, ypu pay for seat assignment if you want to guarentee sitting with you party, you pay for soda. My flight was 1.5 hours late, due to mechanical problem. Plane was janky and it felt like it STILL needed repairs."
Cons: "Low airfare."
Pros: "The price and the nonstop flight."
Cons: "6+ hour delays Plane looked to be in sad shape, paint peeling, looked bolted together from spare parts. Strange Air Conditioning issues mid-flight that turned the plane into a walk-in freezer. upon landing our entire flights bags were abandoned and there wasn't a single Allegiant representative in the airport to communicate with the airport baggage people. After 1.5 hour wait our bags were finally offloaded onto the baggage claim by an airport employee not normally tasked with the job. Allegiant was paged over and over with no response. I will NEVER fly Allegiant again."
Cons: "Delayed 5 hours!"
Cons: "Two out of three bathrooms out of order"
Pros: "Nothing."
Cons: "They overcharge for bags and their weight limit is only 40 pounds. They leave the desk and hour before take off which doesn't help people who are running late. They charge you to print out your boarding pass. They don't even send the boarding pass through email, you have to download the app. Overall horrible customer service. When call for customer service you can't even get a human representative. I missed my flight and they didn't even have another flight to to accommodate me to get to my destination and no one at the front desk to talk to."
Pros: "Airline was great. Told us right away they were only going to do one drink service so we could order two. Left on time and had no issues. Would definitely fly with them again. Even though you have to pay to check a bag, it's still a better deal than any other airline out there. People need to stop complaining about the extra fees, do you want cheap or not."
Cons: "Nothing. Was exactly what I expected for a $35.00 flight."
Pros: "Nothing"
Cons: "5 hour delay. They offered meal vouchers. For 8 dollar like wtf? But of course they offered them after every place closed in the airport."
Pros: "The flight left on time. Friendly crew"
Cons: "I don't like that they charge for carry on bags and they don't have a toll free number"
Pros: "The from take off to landing was smooth"
Cons: "Have no dislikes"
Cons: "I didn't like the schedule time change. Very inconvenient missed some of my planned festivities that were prepaid."
Pros: "Time of travel"
Cons: "No leg room"
Cons: "I wasn’t one of the passengers but it’s unbelievable that United was denying passengers in zone 5 to take their carry on. You can’t take what you are going to use during the flight, it is not normal. Is that a joke or what?"
Pros: "I like that they serve after dinner drinks which will help me to sleep on the plane. Their blankets are better than United. It was a safe flight and I was able to charge my cell phone. I paid for texting and that worked fine for the entire flight. Even with short layover my luggage made it."
Cons: "I was in the last row so it wasn't as comfortable but there were no other aisle seats available. Food was okay but the red wine could have been better."
Pros: "Good entertainment section if you have your personal devices. Menu was better than most anymore (which isn’t saying much)."
Cons: "Attendants allowed drunk travelers to party and gather in the aisles. They were spilling drinks and yelling so loudly “talking” that you could hear them clearly over the engine noise AND headphones, and they kept serving them."
Pros: "Crew"
Cons: "Missed my connecting flight. Had to pay my suitcase extra (60 dollars)."
Pros: "Crew attentive and always offering refreshments."
Cons: "Great flight attendants"
Cons: "Seats were a little uncomfortable but overall not bad."
Pros: "The crew was great, the seat was very comfortable. The flight was quick and seamless."
Cons: "Entertainment system did not work. Wifi did not work so could not use personal devices. Light did not work so couldn't read a book. Looking at the back of the seat in front of me for 5 hours was pretty tedious."
Pros: "The controlled and orderly way when boarding."
Cons: "The staff from the desk was unfriendly. On boarding no one showed you where your seat is located. The food was dreadful. The same aweful pasta meal on the outbound journey was served again. During the flight I was feeling very unwell I asked the flight attendant our axeick bag which she brought, but I was told to go to the toilet. She did not return to enquire after my well being. I was in the toilet for 5 minutes. Very uncaring. The tea was cold when served"
Pros: "Smooth flight"
Cons: "The tray cannot be pullled closer for eating. The seat sitting up is very uncomfortable for reading. I would have liked a pillow. Th poor man in front of me asked for a coke after the meal service was done, and the flight attendant said she had to reserve it for the next flight?! The male announcer flight attendant was very hard to understand, some of his words were slurred and garbled. And the volume was always too loud for both the male and female announcers. There was no entertainment unless you downloaded the app."
Cons: "It appears united is unable to fly their planes on times, in particular on the East Coast. We were delayed by 90min on each legs"
Cons: "My wife and I traveled with bicycles packed in standard boxes and got hit with a whopping $230 charge per bicycle out of the blue. We were expecting no charge because the bicycles were our only check-in baggage for the trip. Couldn't believe the lack of transparency with which we got hit with this charge. Qantas, Air New Zealand, and other airlines we've taken bikes with us on our flights have charged nothing when we traveled in the same fashion. So, if you are a bicyclist traveling with your bicycle, I'd avoid the United-Lufthansa duo."
Cons: "Lufthansa as an agent is a mistake! I had to deal with them prior to flying to the US. I have never ever had to deal with such bad service in my entire life. United was great though and I highly recommend them."
Pros: "The pilots were informative with their announcements and we were informed of turbulence before it started. We also got in ahead of schedule. I also appreciated being able to ask for a glass of water between services as I had fallen asleep."
Cons: "The negative experiences started before we got on the plane. Boarding began slightly behind schedule and was very disorganized. People were all standing in the boarding area and out into the walkway for the concourse. I feel it would be better to have boarding groups come up individually or two at a time. (While group one boards, group two convenes. Once group one has boarded, invite group three to take their place.) Once group three had boarded, an announcement was made that there was no overhead bin space availble for the entirety of group 4. It seems a bit ridiculous that nearly half the plane wouldn’t have overhead space. It took awhile to board group 4 as everyone had luggage to check and once we finally got down the jetway, we had to wait another few minutes before being able to get to our seats as the flight attendant for first class insisted on taking drink orders while she stood in the aisle. I understand this is a perk of first class but I feel it could be better executed. These seats are boarded in group one so to have drink orders incomplete by the time group four is trying to board is irritating at best and incompetent at worst. Once finally at our seats, it became apparent that the announcement about lack of overhead bin space had been made a bit early. The bins were on the full side but they definitely had space available. Also, much of the space had been taken up by jackets and bags that would have fit under the seats; which I felt could have prevented nearly all of the checked bags. The flight was uneventful with minor annoyances like having to pay for entertainment and any sort of food. Even southwest provides entertainment free of charge and I consider them to be more of a budget airline. If I fly Lufthansa again, I will not take a domestic flight through United and will instead book via southwest to and from the international airport Lufthansa flies out of."
Pros: "Despite sitting in the middle seat and being well over 6 feet, there was room."
Pros: "Best flight I have ever experienced!"
Cons: "Nothing"
Pros: "Nothing really everyhing was mediocre."
Cons: "Delayed baggage, smelly flight, food"
Cons: "The food was particularly poor this flight."
Pros: "Clean aircraft good entertainment, cockpit crew polite"
Cons: "The check in staff were unbelievably rude nearly looked and were abrupt and dismissive to a simple question. The cabin crew looked scruffy, and clearly had a lack of pride in their job and presentation. This is the first time I have ever flown United and I must say I would avoid flying with them again if possible, which is a shame and the aircraft and the entertainment on board were good"
Pros: "The check in was good. The craft was clean."
Cons: "Nothing"
Pros: "Crew was very attentive and kind. Plane was clean and comfortable."
Cons: "Food was not good."
Pros: "Staff was pleasant, decent movies overall."
Cons: "I can't eat mushrooms. Both meals had mushrooms (3 out of 4 entrees) and it wasn't always obvious which ones. Additionally, the second meal with seafood or pasta, the pasta obviously had mushrooms so I chose seafood, even though I don't like most seafood. Mushrooms all mixed in with the seafood, so I had to pick them all out. Also 2 of the accompanying sides had mushrooms. Do they have a mushroom fetish like Cheesecake Factory? Need more consideration for people who may have varying food requirements that are unavailable to address during the booking process. I know you can't please everyone, but why overuse an ingredient that has a relatively low appeal to potential passengers? Will try again, just hope they can use similar customer service in their food preparation as they have otherwise."
Pros: "Decent leg room. Wonderful to do the flight non-stop from NYC to Delhi."
Cons: "United. September 14 Newark to Delhi Premium Economy Entertainment screen didn't work for 1st hour of the flight. the movie list was mediocre at best. The screen was smeared with some substance. The list of movies on the United entertainment app is great (via internet) but connectivity on this type of flight is spotty so the traveler is forced back to the antique screen plane system. Dinner. Butter chicken or vegetable options. Food was bland and very small portions for the length of flight. The snack was delivered immediately after dinner was picked up. I did not open it. Looked like a hard roll with something on it. Style of service is abrupt, bordering on rude. Uses terminology that non-US travelers from different cultures would not understand, for instance do you want "white" coffee. Asked me if I had someone at home to pick up after me as she felt she was cleaning too much off the floor. Her comments appeared to be directed at me but it was not my trash (and even if it was, a better approach would be recommended). The flight attendant realized she had gone too far and apologized. Then complained about this "route" being difficult, with no one listening. She concluded by wishing me a good flight and saying that she hoped that she had not offended me. I assured her that she had. Breakfast was mediocre. Egg with soggy potatoes and an inedible sausage. Did not see what they were offering in the veggie dish. Staff seems tired and not culturally sensitive. There needs to be some retraining and consideration given to long haul menus and entertainment. I take this flight at least once a year. It continues to deteriorate."
Pros: "Crew were amazing, so friendly and helpful Entertainment system was so so good Landed early"
Cons: "Overnight wasn't the easiest flight in the seats Serving people coffee when others are probably trying to sleep probably wasn't the wisest idea either Pre flight queue system is just baffling"
Cons: "Been a long time since we had to walk down onto the tarmac to board a plane. Would rather not have to do that. Otherwise a good experience."
Cons: "Navigating thru channels was challenging."
Pros: "Comfortable seats"
Cons: "Boarding took a long time in the plane. There was confusion as they had passengers going both ways in the aisle .. this forced several ppl to stand in the aisle a long time. One of the air hostess had a major attitude. For example one passenger who was stuck in the middle of other passengers asked her politely if she could help him put the carry on in an overhead bin near her .. and she responded "I cant help you, you need to put it up yourself sir". Not something one expects. She was also terse with passengers, ordering them in an annoyed tone."
Pros: "Good leg room"
Cons: "Had ro pay for entertainment"
Cons: "United check-in at IAD was chaotic. Worst process I have ever seen."
Cons: "I had a man sit next to me who was in the wrong seat but didn't move. He told the girl to keep his seat and he would stay next to me. He was so big he was in my space and had didn't make any effort to try not to spill over in my area. I had to put a magazine next to my thigh because his body was so hot it was damp! I hated the entire trip. I was cramped up and extremely uncomfortable. This is simply unacceptable to have this happen because huge people can't fit in one seat. I want these obese people to be required to purchase 2 seats because they take mine."
Pros: "Great service from the flight crew, comfortable plane, in-flight movies and entertainment."
Cons: "United service was uniformly poor. When we checked in at Dulles Airport, we had to go to two different counters to send our luggage. The United check-in / baggage attendant determined that two of my bags were 'oversized.' I have travelled dozens of times with these same bags, including on this trip, and none of the airport determined the bags to be oversized. The United seats, which we had purchased as "Premium Economy" from the Lufthansa site were "Economy Plus" and not worth the extra $ 275 per seat. The United plane was not well-maintained and had several obvious defects. If United wants "Star AlliNCE" to mean something, they need to do as well as Lufthansa."
Pros: "Friendly staff, great customer service"
Cons: "None"
Cons: "Again a full flight and this time I was seated next to an Asian male. I'm deal thy allergic to fish and what did he bring to eat, yep you got it. While I know it's a right for him to do so, I spent the flight with puffed eyes and throat issues. Again, the flight was overbooked"
Cons: "2 hours delay"
Pros: "Flight was on time, except that we had to wait a few minutes for more oxygen to be boarded because the flight was completely flow (overbook in fact)."
Cons: "Both my daughter's and my seats were broken. We were not given seats until just before boarding, luckily they were together."
Pros: "Flight crew in Dulles were very helpful in arranging for my daughter and I to sit together. Really appreciated their help."
Pros: "The stewards were nice and they were prompt. The plane seemed to be well cleaned inside and they were quick to get everyone boarded and bags stowed underneath. The pilot knew what he was doing and I had no worries there. Everyone was doing their jobs as well as they could be done."
Cons: "The air nozzle above my seat was broken and would not turn off so I freezing the entire flight, as well as the tray table seeming like it was meant for the lap of an infant versus myself and I can't imagine how someone with longer legs than myself dealt with the way it folded down. The take off was rough either seemingly due to tires or perhaps a rough runway. The wifi on the plane would not work. It worked ok my first flight but not on the second. I don't know why and no one knew why either, had the latest app and it was updated to the current version."
Pros: "NOTHING"
Cons: "I booked a one way flight to Dallas (DFW) for my father and I using Kayak to leave from washington D.C. (IAD) 05:30 PM - 08:04 PM United Airlines Flight 6296 Operated by Oriental Air Bridge I booked it for Saturday January 21st and it went to pricline.com and confirmed it. The problem is that when I looked on the confirmation email/boarding pass it said I was supposed to be leaving January 20th, so as you could tell on my account I had to purchase another 2 tickets with another airline. I don't know what happened but I am very disappointed. I would like a refund please. Abdallah mohammad ismail Abdallahismail84@gmail.com 469-396 3589"
Pros: "The crew was good."
Cons: "I paid for the internet that never worked. I couldn't watch a movie or TV either. It was t just me, a lot of people around me had the same issue."
Pros: "Nothing"
Cons: "Flight UA 6270 was initially delayed due to incoming plane delayed for weather. After boarding 2 planes at IAD, we were told after 5 + hrs that the flight to JAX was cancelled. UA Customer Service Agent was slow and not well trained. Other passengers were easily and promptly placed on other flights (UA & other airlines)...we were told that the next available UA flight from IAD to JAX was more than 24 hrs wait. Eventually placed on a UA Flt to CLT at 11 PM. Upon arrival in CLT, we asked the gate Agent for assistance on a Voucher because we had to stay overnight in CLT...we were told that the IAD Agent did not designate us as eligible for a voucher and yet, people next to us flying coach were given a voucher. The Gentleman Agent at our arrival gate was trying to help us but his Madam Supervisor was arrogant and unwilling to help. In an exasperated tone, I asked both individuals if flying First Class would help us get a voucher and her arrogant answer was "do you want me to call the police?" Obviously we left for our Marriott Hotel which was a wonderful customer service experience. Plus our UA Flt from IAD to CLT placed us in Coach (is a refund coming???) We paid for 1st Class for our 12/22 flight and our 12/26 flight. After 3 hrs in a Marriott in CLT we took an AA Flt from CLT to JAX. Also, the UA communication on the status of our baggage was unclear and misleading. Plan to fly American or Delta for future travel."
Pros: "The flight overall was great, easy to board and de-board, and a smooth process from start to finish."
Cons: "Connecting to the in-flight wi-fi to watch movies and tv shows was nearly impossible."
Pros: "Boarding was fast and easy. Crew was kind to allow me to use an empty seat in the middle row and get more space. Managed to connect to onboard entertainment with a tablet and avoided to use the tiny screen that still exists on United's 767s."
Cons: "Food was a bit tasteless."
Pros: "This plane was smaller so I got to sit by myself so it was more comfortable for me"
Cons: "Lack of drinks/ comp snacks"
Pros: "Aircraft remained grounded for 1h due to a door switch with malfunction."
Pros: "Very smooth and comfortable flight."
Cons: "So we arrived at the desk after a 7hr international flight ready for the final 1hr leg - only to be confronted with "flight overbooked" looking for 9 volunteers - how can you over book a 40 seat flight by 9 ???? So we had an anxious wait wondering if we'd be dumped from the flight - we weren't but it wasn't enjoyable waiting for the flight and our meeting with our grand kids."
Cons: "A la ahora de irnos hubo muchos contratiempo por el tiempo pero por el vuelo después que nos fuimos fue excelente"
Cons: "I was thoroughly disappointed when I realized that I had to pay to get any type of entertainment on the in-flight screen. That feels like zero effort on the part of the airline to make my flight enjoyable."
