Pros: "Alaska Airlines is the best."

Pros: "The male steward was very nice"
Cons: "Flight was delayed on tarmac for 2 hours better communication"

Cons: "Delayed boarding but received notification from Kayak was good."

Pros: "Friendly crew. Great movie selection through gogo inflight entertainment!"

Pros: "Aircraft was clean and comfortable. Crew was efficient and friendly. The whole experience was excellent!"
Cons: "There was lots of entertainment available but plain old music was not an option. What if I don't want to watch a movie or TV, just listen to music!"

Cons: "Seat cushions are too thin."

Pros: "Great on time too"
Cons: "Very happy"

Pros: "Direct flight"
Cons: "N/A"

Pros: "The seat was comfortable and the plane wasn’t over booked."
Cons: "I didn’t like that we took off an hour late."

Cons: "Two rows up from us, I kid threw up all over the center aisle as we were pulling away from the gate. We returned to the gate to allow a cleaning crew to board and clean. However, the cleaning job was rushed and left remnants of the throw up behind which smelled the whole 2.5 hour flight. It really felt unsanitary and unsafe being that it’s unknown what caused the child to get sick. It very well could have been a stomach virus and could have infected the people in rows around the incident due to the mediocre cleaning job. I understand that it’s important to keep flights on-time, especially for connecting flights, but the safety of the passengers and their health should ALWAYS be the #1 priority."

Pros: "The flight attendants were friendly and professional and took time for a little personal conversation."

Pros: "Comfortable seats with nice details; power ports; drinks and snacks."
Cons: "Boarding in Seattle was ridiculous. Security took a massive amount of time, and we barely arrived in time for th flight despite arriving hours early. The attendants at the gate were a bit rude and begrudgingly accommodating."

Cons: "I missed the flight"

Pros: "- Crew was friendly as usual"
Cons: "- The plane was a bit older, so the seats were not as comfortable as most Alaska flights"

Cons: "i wish Alaska would fly straight to Denver from Montana. I fly from Montana to Denver a lot and it ends up being a whole day of travel instead of a couple hour flight."

Cons: "Boarding was a hassle. The flight was too crowded. The food was non-existent.. Seats were uncomfortable."

Pros: "It was on time and friendly"

Cons: "Food and wine way over priced."

Pros: "Boarding was a breeze, crew communicated well, seats were comfortable, plane wasn't too hot or too cold"
Cons: "Had a problem with checking my baggage in anchorage which led to $300 being held from my account for 5 days. They refunded my baggage fee though"

Pros: "Everything but…"
Cons: "You lost my backpack with $2000 worth of hiking gear that I will not be able to replace before I am supposed to leave on a trip. How could this happen?! This bag was full of all the material possessions in the world that matter to me."

Pros: "Seat was comfortable and in-flight service was very good."
Cons: "Gogoinflight didn't work for at least the first 30 minutes of flight. I upgraded to first class, but there was no service until we were above 10,000 feet. I don't know if this was a one-time thing, or if other airlines are just better at accommodating first class."

Pros: "Friendly staff. Made up time after a mandatory tire change."
Cons: "Other passengers not listening to the staff."

Pros: "On time and effortless."

Pros: "Able to text ..."
Cons: "No Free beer or alternative gluten free snack"

Cons: "Gate 11c."

Cons: "Nada"

Cons: "not able to know my seat till a day before flight ."

Pros: "Almost everything. First time flying with Alaska Airlines thought the food would be better o thought the food would be better on such a long flight but it was enough to snack on until I got to Seattle great experience in between flights was able to get an earlier flight to Denver"
Cons: "Wish there was a little bit more offered for food but overall a fantastic experience mahalo"

Pros: "Just fine. Staff was helpful and actually very kind crew (stewardess) I don't recall her name but middle aged blond. Very nice."
Cons: "Charis could have more room and there was bad turbulence but what can be done about that? we arrived safe and sound and that was good."

Cons: "Service was amazing"

Pros: "entertainment"
Cons: "very rough landing, delayed flight with little communication"

Pros: "Great service and very organized."

Pros: "Early flight, and short. I think I slept through it. Woke up sore, but eh I'm not surprised by that. I'm a giant and no one woke me up for anything so I was satisfied."

Pros: "The crew and captain were amazing and very apologetic!"
Cons: "I paid an extra $300 for preferred seating because I wanted the extra legroom to sleep. I'm over 6 feet so coach is very uncomfortable. My girlfriend and I got in our seats and 10 minutes later, a crew member walked back and asked us to get off the flight. We got off the flight and were met by police officer. Low and behold, the woman sitting next to us said that she believed we were intoxicated and feared for her safety. I am a police officer and my girlfriend is a nanny/preschool teacher. Not very threatening. The officer on the ground looked us over and asked us a few questions and determined we were not intoxicated and we were no threat to the other passengers. The airline asked us to get back on the flight and we would be sitting in coach because the woman adult children were now sitting in our seats. I told them to book us on another flight with the same seats that I PAID for or put us back in OUR seats on that same flight we just got kicked off of. We were escorted back onto the flight and the crew asked the woman's children to go back to their seats so we could have our seats back. They then asked us not to speak to the woman sitting next to us (which we never did to begin with!!!) and then told us we could have free food and drinks. The whole experience was insanely embarrassed and I can't believe that woman sitting next to us can get away with what she did. I am absolutely livid that they would ask us to get off the flight and then give our seats to the woman's ADULT children without vetting the situation and making the easy determination that we were NOT intoxicated. So embarrassing!!"

Pros: "Glad I discovered Alaska Airlines!"

Pros: "It got cancelled due to 3 inch of snow. And I missed work in Denver because of it. Very inconvenient"
Cons: "I would like to not have it cancel"

Pros: "Offering price"
Cons: "Real price. Ridiculous after carry-on and other fees"

Pros: "Ditto statements above"
Cons: "Ditto statements above"

Pros: "good"

Pros: "Their staff was awesome as usual no issues with the flight ."
Cons: "So many bags that were suppose to go under the seat infront of you that weren't. So that those of us that boarded last had to wait while stewarts removed small carry ons. So that our one carry on that fit in the box but not under the seat could be stowed. It would be nice if the smalls bags that are to be stowed under the seat were. The family next to me had 9 bags in the over head. There were two adults and two children 3 and 4."

Cons: "Nicest people ever."

Pros: "Alaska airlines is absolutely wonderful. Friendly, happy and simple..."

Pros: "Roomy seats and plenty of legroom"
Cons: "The whole experience of making a connection in SEA detracts from the travel experience. There is little room for passengers to sit while waiting for their Alaska flight. It causes masses of people in the walkways, and makes it hard to walk through, or get out of the way for others. It may not be the airline's fault, but as I said, it detracted. I don't remember SEA being that overcrowded on previous trips. Our incoming flight was delayed due to weather. Again, not the airline's fault, but we were told we'd be able to make up the time and be on time in DEN. We were still late."

Pros: "Went very well. Not stupid"

"The plane was SO hot and we waiting 30 min for one passenger to get on. Sweating. Then the plane never cooled off because it got SO hot waiting."

Pros: "Everything basically"
Cons: "Nothing"

Pros: "Crew was great."
Cons: "turbulence"

Pros: "1st class flight attendant sat through the entire flight (except for offering drinks and food early in flight). There were passengers NOT wearing masks through the flight but she wouldn't know that since she never left her seat"
Cons: "just about everyting"

Cons: "IFE was not streaming movies, WiFi on but not loading"

Cons: "Spacing people out until this covid is over"

Cons: "There are too many announcements on the screen before you can start watching entertainment. It takes about 15 minutes."

Cons: "Short flight, would have appreciated if when asking for pretzels the flaggt attendant didn't hand me the spare bag of his pockets."

Pros: "Really enjoy flying first class."
Cons: "Excellent"

Pros: "Crew was nice"
Cons: "Could not connect to wifi."

Cons: "The plane we needed for our flight arrived really late so our flight was then of course delayed."

Pros: "Everything was great"
Cons: "Nothing"

Pros: "Good entertainment choices."
Cons: "Uncomfortable seat with insufficient legroom wouldn't recline. Inadequate overhead storage (full flight)"

Pros: "Appreciated the pilot keeping us informed re: turbulence and avoiding it"

Pros: "Even on a full flight, there was enough overhead storage"
Cons: "Pretzels were lame"

Cons: "Flight got delayed. We paid for assigned seating for our almost 85 yo mom. And the change in flight no one asked for to get seated in the front of plane. Instead she was seated all the way in the back. It was physically exhausting for her."

Pros: "The crew was polite and professional"
Cons: "At Miami check in, American had 40-60 automated terminals available for self check, but only had EIGHT open for use. Caused a needless bottleneck and the transition from there to the bag drop was also poorly laid out and did not provide a logical nor efficient route from one to the other. fix it!"

Pros: "On time flight. We were even a little early."
Cons: "Those seats are just crammed in there aren’t they?"

Pros: "The notifications regarding my connection and baggage claim."
Cons: "Nothing."

Pros: "Crew was great"
Cons: "Absolutely no accommodation for seat assignments and the lady at the gate was so rude for even just asking to sit next to my fiancé even though there were tons of single people on the flight."

Pros: "No major screw-ups this time!"
Cons: "It's AA, let's not try too hard here."

Pros: "Crew was nice"
Cons: "Not enough leg room. They did a gate change and I almost missed the flight because nothing was announced and when I looked at my phone app it had the previous gate."

Cons: "Flight was delayed so had to drive to connecting city just to make it home."

Cons: "The sound on the entertainment system in my seat didn't work well. Also, the flight was really late getting in to Denver."

Pros: "Friendly crew"
Cons: "Tight seating leg room non existent."

Pros: "Not using kayak."
Cons: "Worst flights in history. It took three days to get from Italy to the US. Do not use kayak!"

Cons: "Didn't like the two hour delay, especially when I was notified only a half hour before boarding! This seems to be a normal thing for American Airlines."

Cons: "Flight departure was delayed for 30 mins by a flight attendant not showing up on time."

Pros: "Seats were too tight and too close together."

Cons: "Flight crew was late and didn’t try and make things move faster to make up time. Kept saying they wanted to go Puerto Rico and that’s where they should have been going."

Cons: "Flight was delayed by 90 minutes because the incflight mint flight was late"

Cons: "the drink service came through pretty late in the flight. i asked for hot tea. a few minutes later i was provided with extremely hot tea. about 10 minutes later it was a temperature i could tolerate drinking. about 1/3 through the drink i was required to throw away my drink because we were preparing for landing. i understand that, fine. bad timing. it’s just a drink. what was unsatisfactory is that the attendant rudely commented “you have to give us your drink. it’s not that long of a flight.” the comment made me feel like i had done something wrong even though i had just been drinking my tea as soon as it was at a drinkable temperature. i was not impressed with the attendant. also, there weren’t any biscotti cookies."

Pros: "The first leg had awesome pasta.Then, on the 2nd leg, Philly to Denver, they had a "pay for meal" option for turkey with Chutney sandwich - again, delicious. I should add that the service was very good as well."

Pros: "Getting home 20 minutes earlier than scheduled"
Cons: "Pretzels are always stale"

Pros: "it was fine. flight left on time and the crew was nice."
Cons: "that you have to pay $100+ for economy plus to get the legroom you used to get for a regular ticket."

Cons: "the new seats are awful"

Pros: "It’s been a while since I’ve flown American, but the aircraft was updated with a solid multimedia system, great moving map, and a standard power plug and USB port at every seat. That’s more than I expected, and was quite happy. Service was solid—no complaints."
Cons: "Good & bad — flight arrived late, but the honestly, the pilots did their level best to make up the time and managed to arrive w/in 4 minutes of the scheduled arrival. Well done."

Pros: "Confusion, delays, rude employees...you name it, this trip had it. I will do my best to avoid flying with these guys in the future."
Cons: "Flight delayed 15 hours. Poor communication and outright lies from staff. Unwillingness to help find or pay for a place to spend the night. Rude staff"

Cons: "Watched a very weird interaction between Muslim (with a hajib) women with a kiddo and desk crew. She wanted to sit next to her child on the flight and needed to switch seats to be able to. Woman was very gracious and understanding that she was asking for an accommodation. Ends up her flight to Philly had been moved to a different gate after they had found a volunteer to switch seats. Volunteer was totally unfazed but Desk crew made it seem as tho the Muslim mom was at fault for the time and trouble they had had to go through to accommodate her. She apologized profusely and was very appreciative for the trouble evernote had gone to for her. . As she walked away the crew looked at each other and shook their heads. Pretty crummy way to treat customers!"

Pros: "Good serice,"
Cons: "Good service to switch flight pattern from greenville to new bern but still a delay that cause a 2 flight connection. Lots of on-line issues with check-in, overall a stressful day, hopefully it will all work out!"

Pros: "Missed the flight. Money was not refunded."
Cons: "Nothing"

Cons: "I can't rate it because they canceled my entire itinerary without so much as an email. I did not take my flight to Wilmington via my original flight. I had to book another flight because the change fees were too expensive. I did not know that my return flight to Denver had been canceled until I was checking in a few hours before my flight. I was told my ticket had no value. Awesome! It really stings that I then had to book a new return flight, and because I am a teacher who makes about $23,000 a year, I had to book the cheapest flight, which was with American. I do not plan on giving them any of my hard-earned money in the future if I can help it."

Pros: "Flight was on time through United since we had to be rescheduled from our original flight with American."

Pros: "The crew were as nice and accommodating as they could be considering the situation."
Cons: "Three planes with "maintenance" issues and not able to fly? Including flights that weren't ours. Boarding, re-boarding, leaving four hours late and waiting an hour for bags in Denver."

Cons: "Flight was delayed and then extended by 2 hours due to weather."

Pros: "Entertainment."
Cons: "We sat on the runway for 3.5 hours while the crew cleaned up a fuel spill and we waited for a different co-pilot."

Pros: "Crew"
Cons: "Had to board three times, two different planes. I understand mechanical problems, but 3 hours later, and on another plane, the captain starts making stuff up, saying that the only reason we hadn't moved in the last hour was because people were using the bathroom, then something about having to deplane because the plane couldn't back up with us on it because of some sensor? And then, surprise ! All of the sudden they noticed there was an issue with his and some of the crews' hours and we had to wait till they could locate more crew. But they gave us each a 1/3 glass of water and later a $12 food voucher which didn't even cover a meal and beverage. Whoop-de-do. 7 hours later we finally boarded for the third and last time. The crew on the other hand stayed professional and friendly."

Cons: "Seats too small and the gentleman next to me was a big guy so crowded over into my seat some."

Pros: "American Airlines is my favorite Airlines to fly. There is a little more leg room and the seats are a little wider. The staff is very professional and courteous."

Cons: "The customer service from AA representitives in the airport was completely unnacceptable and the absolute worst service I have recieved in an airport to date! One incident during this trip was as follows: When arriving in Charlotte and running to catch my connecting flight, I arrived as the lady at the desk was closing the door, she looked at me and rolled her eyes. When I went up to the desk along with the other passengers arriving from the same flight as me the AA representative said "Hurry up , I want to go home!! At a point I'm just going to cut you off and that will be it!" She was of no help to me in anyway amd was forced tonstay the night in charlotte ; Normally this would not have been such a big deal, However I am on emergency leave from the Navy rushing home because I have a very serious family emergency, that representitive was very lucky I held my temper! From now on thanks to the poor unproffessional customer service I received I will no longer be flying American Airlines!"

"I didn’t eat any of the snacks nor drink any of the beverages available on the flight. I tend to fall asleep on the plane, which is what happened. It has been a while since I have flown United, I appreciated the spacious seating, comfortable seats and improved planes. Thanks for making the flight easy and enjoyable, it seems like the company has been working on making general improvements to their flights and it’s paying off."

"No food. Got a window seat and of course 21a had no window just a perfect panel of plastic"

"Bad information from Kayak. unhelpful and confusing."

"No food…. : ( - we survived!"

Cons: "Row 39 seat F extremely uncomfortable!!!!"

Pros: "The crew was fine"
Cons: "No open seats at all. Old cramped A319"

Cons: "Video entertainment did not work properly. Stewardess reset it but audio was totally garbled. I tried it with three different sets of earphones."

Pros: "It got me on the way"
Cons: "An outlet and letting me get into Canada"

Pros: "Crew was amazing."
Cons: "It would have been nice to depart within an hour of my original time."

Pros: "The captain spoke clearly and have good information."
Cons: "The flight was fully packed during this Covid time. There was zero social distancing in place."

Cons: "More comfortable seats. More distance between passengers."

Cons: "The boarding and social distancing being funny with the process"

Pros: "Flight was packed in like sardines. Seat was uncomfortable"
Cons: "Have passengers sir at every other seat."

Pros: "The staff"
Cons: "Plane was way to full like sardines. The middle seat should be empty for Covid !!"

Pros: "Everything"

Pros: "Very good and safe"
Cons: "Everything was great"

Pros: "Clean aircraft helpful staff"

Pros: "Everything was cool, smooth flight"

Cons: "Smelled like pee for half time we were up and announcer was very annoying , she sounded like she is about to pass out , short of breath like she needs an ambulance. Statement about wearing masks was just too much... we get it - we wear masks."

Pros: "I liked my seat"
Cons: "There was a stewardess that was very mean and not accommodating when I asked for a mask"

Cons: "ANYTHING more than what’s being done in economy would be good."

Pros: "Crew quiet and professional"
Cons: "Screaming child boarded"

Pros: "Very organized and helpful. I felt safe."
Cons: "Different types of snack. Nothing serious to complain about."

Pros: "Yes"

Pros: "The crew was nice. When I finally arrived in Denver, Marlin in customer service was the only saving grace for United for me. When I asked for options for an earlier flight into Rapid City so I didn’t have to wait 24 hours and miss my visit with my sister, he looked at different hubs (Chicago, Minneapolis) to see if they had any available flights into Rapid, he checked for double bookings, and when he couldn’t find anything, he put me on the standby list for the first flight out in the morning and wrote down the flight information for all of the United flights from Denver for the following day. Marlin provided excellent customer service and was a huge credit to the company."
Cons: "The flight was supposed to leave at 3:56 pm and didn’t leave until 7:30 pm. I would estimate at least 15-20 people missed connecting flights because of the delay. According to the United app, the delay initially started in Portland due to mechanical issues, which took over 3 hours. Then, there was a weather delay in San Francisco according to the gate agent - there was a ground hold and no planes were landing or flying out. At some point, I would think another plane would have been an option rather than delaying a flight for this long and disrupting holiday travel for so many people."

Pros: "The flight was great. No complains to the crew."
Cons: "The drop-off bags at LAX is a mess and you have to stand in two separate lines to drop off your bag. First you have to print the tag and then go to another long line be with 2 employees only to drop it of instead of having one place to print and drop off at the same time. Poor system. Moreover while there was plenty of time my bag did not make it on the same flight. It will arrive on the next flight hopefully. I had to wait in another line for 30 minutes to arrange the delivery and verify all my information. I truly believe that to make a trip great both arms - the airport and the flight experience should be perfect. Unfortunately the ground experience does not allow me to give a higher rating."

Cons: "I paid $100 for an upgrade on a United which turned out to be the first row, and right beside the rest room (which was erroneously showing as occupied for the first 20 minutes). The traffic made it feel like I was sitting on a bench in Grand Central Station. I chose an aisle seat but ended up mysteriously in the middle seat. I had extra leg room but if I’d eaten the free 5 pretzels I wouldn’t have been able to fit it my seat any longer. The WiFi wasn’t working for the first hour of the flight. The flight attendant got really annoyed when we didn’t look up when he came by with beverages the first time. We all had headphones on and were looking at our personal screens. The activity by the rest room was constant so we didn’t notice it wasn’t just someone waiting for the loo. The luggage took so long to come out I thought my conference would be over before I got it. Overall, I thought it was bad and confirmed why I don’t fly United. Old, dingy planes, poor service. The pilot was pleasant and communicative so there was at least that..."

Pros: "For all the turbulence that we heard about, the flight was extremely smooth which I attribute to the pilot's skills"
Cons: "We kept on being told that there was going to be turbulence and that it would be too rocky to serve food/drinks - but there was limited turbulence and the flight was very smooth. There was also a delay in leaving as there was an extra bag in hold but they 'couldn't find it'."

Pros: "That I eventually made it home."
Cons: "Flight from Calgary to Denver delayed three and half hours. Informed of this delay thirty minutes before scheduled departure when our plane hadn’t even left Denver yet to head to Calgary. ( 2.5 hr flight) once finally made it to Denver was informed that we missed connecting flight to Boston. We were then informed since it’s for “weather” reasons earlier in the day that caused a sequence of delays they couldn’t accommodate us for hotel. We were given two “blankets” which were as thin as a sheet and each one bottle of water. Some other people around us received good voucherS. We did not. We walked around the airport for close to an hour looking for anyplace we could lay down and sleep. None were to be found. We tried to sleep on the floor but was so cold and uncomfortable I literally got sick to my stomach. Another fun thing added to mix. We were placed on another flight as 6 the next morning. After no sleeping at all we boarded our next flight Which was not a direct flight to Boston but would be from Denver to Newark then Newark to Boston. We were suppose to originally land in Boston at 0600 Monday. Instead we arrived at 1430 after getting zero sleep. My husband and I were also unable to sit together which was extra special for people around me because after not sleeping I continued to be sick to my stomach."

Cons: "Carmel waffle cookie"

Pros: "Seats were comfortable, we were in first class. United provided a good selection of recent movies."
Cons: "United stewardesses have little to no interest in their duties. Questions were clearly an annoyance to them. The leg of flight from Denver to Des Moines was very uncomfortable, seats much to tigh, no leg room. Gate staff in Denver were exceptional. United needs to revisit their time for loading. We preloaded, I had a broken leg, I was traveling with a special needs woman. We just reached our seats when other passengers were prodding us to sit so they could board no time to settle. Not impressed"

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: "For the first time I did not fly on a puddle jumper. Not only was it a real jet, it had good seat comfort and leg room even in economy class. The crew was friendly and attentive. They came by with offerings of water at least 4 times for a 2+ hour flight. Contrast that with my last two 5 hour flights on Virgin and American where they came by with water — ONCE. WiFi wasn’t working for either flight and of course the lack of decent food is discouraging. The coffee has improved which is a plus. Overall, good job, United! Nice not to be jammed in like sardines for once."
Cons: "Every time I fly to Denver, we land in one terminal and your connection is in another terminal that requires a train ride to get there. ,ayovers are short — generally barely an hour. If the flight is late you stand a very good chance of missing your connection, as I’m betting happened to over half the passengers on this flight. I was the lucky exception — this aircraft was actually the connecting flight too. Why can’t all United connections be in the same terminal? It makes no sense."

Pros: "The flight was on time"
Cons: "This was a smaller plane (4 seats across). Knowing this, they didn't bring enough luggage carts, so they only brought some of the luggage to the baggage claim and didn't tell us this. 5-6 of us waited and waited and finally asked someone who told us that they had to go back to the plane to get the rest of the luggage. Those of us still waiting got to wait another half hour for our luggage. Talk all they want, United just can't seem to get it right. PS: those of us who had to wait were the ones who got to the San Antonio airport the earliest and thus our luggage was on the plane first."

Pros: "We will never fly united... NEVER EVER AGAIN"
Cons: "United airlines employee Mearle at the check in counter was extremely disrespectful, Rude, and arrogant towards everyone in line at the counter Trying to check in. Many customers including us waitted in the check in line for 35 minutes or more while Mearle proceeded to chat on her cell phone (personal call), and taking a break leaning the check in counter while everyone waited on her so she could assist with check in. Finally the passengers in front of us voice their concern to mearle stating that everyone is going to miss theirs flights if she didn't assist us all right away. Mearle responded by snapping back by saying "it's not my fault that united keep us understaffed and pay us enough to care " then laughed and walked away again. At this point we realized that if we did not get immediate assistance, that we would surly miss our flight. I walked in front of the line on behalf of everyone standing in line and reiterated to Mearle in a firm tone that she insisting check in the remaining 12 passengers immediately. Mearle snapped back telling me to "worry about my own self and don't tell me how to do my own job". Feeling very stressed out And worried about missing my flight went and stood back in line again. A few moments later I over heard Mearle tell the passengers ahead of us " you're too late. You've missed your flight" these passengers became very upset with Mearle telling her that she's the reason they missed the flight and Mearle laughed and said out loud to everyone else in line.. "you all missed your flight. You all should be more responsible next time and get here earlier" and then Mearle walked away never to be see again. Many of us missed our flight which caused many of us to also miss our connecting flights. We immediately called the 800 number and filed a complaint. Then we were forced to drive three hours in traffic to LAX where we caught a later flight and barely made it to our destination in time for our work event. We swore that because of Mearle and her disgusting behavior that we will never ever fly united again (and I fly a lot for my job) and since that horrible experience with Mearle two months ago, I've flown on four trips spending over $2300 dollars and every flight has been booked through American Airlines. Do to Mearle's bad attitude, disrespectful personality, and poor representation of united we will never do business with united again. We suggest united airlines remove Mearle from Having any contact with the general public as we are sure that Mearle is loosing customers for united at a very rapid pace."

Cons: "Seats to small. But I am 6'3"" and my son traveling with me is 6'5"."

Cons: "My flights got changed and seat assignments changed so I did not get xtra leg room as I needed Also united did not know that I had a service dog even though I booked with that information"

Pros: "Nothing about this airline."
Cons: "The crew at the gate was really rude. Zero customer service. She raised her voice at us and another customer who was charged $50 for our carry on. Not only was the flight delayed for over 2 hours. We were not informed that we could not bring a carry on even when we were at the main entrance with an agent for over 30 mins when you entered the airport. All their staff needs new training everyone kept on giving us a different answer. We asked because of this delayed will our room be comp due to the fact we will be missing our connected flight. On the phone the agent said yes. When we got to the airport that agent said no. When we got on the plane that agent said no. When we landed in Denver that agent comp our room. We ended up booking a room making sure we had a place to stay at night. It created more work for us because we were trying to cancel our room took even more time. Definitely wanted to give United the benefit of the doubt that they were at least at the level of American Airlines. The last time we flew United it was delayed for 8 hours they ended up canceling the flight. When we called they said it was the weather and we told that agent it's mechanical issue because we are watching someone remove the engine. We will stick to American Airlines. Free entertainment."

Pros: "Flight was smooth and on time"
Cons: "The boarding gate attendants were rude and uncaring when we asked them to help us switch pre-assigned seats to ensure our two year old sat with us. While we might have understood better had they been empathetic, they were rude and uncaring and said when you book online you sign a waiver and they can not do anything about this. Wow. This was our flight back. Originally on the way to our destination we had used Delta and that customer service experience was completely different even though that flight was full too. Never flying United again as long as I can avoid it."

Pros: "free movies on the flight with the united app"
Cons: "The flight attendant was late delaying boarding 20 minutes. Once they started, people were lining up to board. This is a normal behavior however, there employee decided to stop boarding because she said people were crowding. she stop boarding for another 20 minutes. Now, this was a large flight and there wasn't enough room for everyone to stand off to the side. She was rude and there was no reason for this especially when the flight attendant was already late. The plane was delayed 45 minutes due to this"

Pros: "Nothing I won't be flying united again!"
Cons: "The lady at the gate when boarding was not friendly and was not willing to help us get seats together. I was traveling with my mother, husband and two infant children. And it was like pulling teeth to get any information out of her. She did not even tell us we could board early to get situated on plane! I also called earlier that morning and spoke with a man on he phone at united who told me he put us all in the same row. That was a lie bc when we checked in at the gate to get our seats the lady said no one was sitting next to each other! That lady was rude and short tempered! Awful experience will never fly again!!"

Cons: "I told the checkin agent that I would need a wheelchair at the Denver and OHare airports. I told the flight attendant on both flights. I would need a wheelchair at arrival. No wheelchairs for me. At Dwnver they were able to find one for me but with no one to push me. Eventually the pilot who flew us to Denver stepped in and got me to my connecting flight gate, bless his heart. At OHare no wheelchairs for anyone who had requested one. Complete chaos. I finally had to walk to my connecting flight from terminal C to terminal B. Very exhausting for someone with cancer who is exhausted most of the time. Your wheelchair service is completely ineffective, disappointing and a cruel joke."

Cons: "Unable to pre-check online. Unable to check at the check in machines--had to go up and check in at the counter, long wait because there was only one clerk. We were then given a ticket just to get through security and had to check in a second time when we get to the gate for seat assignment, which is ridiculous. Why couldn't that be done at the 1st check-in? The clerk told me she will call me when she has the seat assignment/ boarding ticket but she never did and I had to go back up to ask for them when it was getting close to boarding time. At the last moment minutes, volunteers could check in their carry on for free....It would have been nice (and less hassle) to have that option at the 1st check-in."

Pros: "Once flight began it ran quite smooth"
Cons: "I chose seats when I booked the tickets. So... Not quite sure how both myself and my partner didn't end up seated together, and both ended up in a middle seat sandwiched between 2 overweight people... Are you little people profiling to break up the overwhelming number of big people? another couple with 2 kids were also broken up into distant areas on the plane. I know everyone complains about so many things, and this wasn't the end of the world, but still, it's not ideal. The seating/etc seemed more disorganized than usual for this flight."

Pros: "Nothing"
Cons: "I'm usually a patient person, but my flight was supposed to leave at 525am and didn't leave until 730. This was the first flight in the morning. We boarded, waiting 30 minutes on the plane, they told us to get off because there were computer issues. Why wasn't that checked before everybody was boarded? Once we got on the plane we had to wait another 30 minutes for the crew to get someone's luggage from under the plane. Why wasn't that done while the computer was getting fixed? I didn't get to Denver until 1040am missed my flight and didn't get to get on my connection until 500pm. In the meantime I called to get on a different flight at 1, but the guy on the phone didn't actually book me a seat. The gate people weren't very nice."

Cons: "About two hours before my flight, it was canceled after previously making an airplane switch the night before after checking in online. The I received an email while I was on the way to the airport saying that the airplane that I was going to fly out on was canceled due to airplane maintenance. While I am happy they didn't fly the plane while needing maintenance, they should have planned ahead and known of the maintenance or had a backup ready to go. Obviously it must have been something they just found, but in the big picture of things. You have to pay an way to much for a flight as it is. They should have to solve their own issues to honor their part of the contract. We (as customers) can't cancel a flight with out penalties. Why shouldn't they have to do the same?"

Pros: "Smooth boarding. Friendly crew. Got us there on time, despite a late start That included a gate change."
Cons: "Was asked to check my carry on bag, because the flight was full. Meaning they sold the seat I purchased for my wife (who was unable to make the flight). I did so, but when I looked in the overhead bin after the flight, it was empty. When we arrived in Denver, I waited at the baggage carousel, watched everyone pick up there bags, until there were only 5 or 6 bags going around. I then went to a counter behind the carousel and asked about my bag. I was only then told that my bag had been there the whole time I was waiting."

Pros: "Very friendly and helpful staff."
Cons: "The fact that we had a connecting flight to minot from Denver. Arrived late to Denver because of weather, but my stroller that I had left on the jetway in Seattle was never put on the plane which I didn't know until I got to minot. I was going to wait for it in denver, but I would have missed my flight to minot had I waited 5 more minutes. We arrived to minot only to find out that our 3 suitcases, one stroller and 2 car seats were never in the flight. Awful! And my connecting flight was even delayed an extra 55 min so I don't quite know where my things are."

Pros: "The flight was smooth. And the wine was good."
Cons: "I paid for 2 round trip tickets and because my son was not there for the first leg, they resold the seat. So they got my money and the other person's money for the same seat. I wanted both seats and paid for both seats. It is theft and should not be allowed. The flight attendant was extremely rude and dismissive. It is a poor practice. You could have at least asked first before rebooking the seat. At least have offered compensation or something. I probably would have said yes Anyway. It's the principle of the process being wrong to the consumer which only benefits the corporation."

Cons: "My flight was scheduled to leave at 4:51 pm. I arrived at the airport 2 and a half hours before my flight was to leave and I read the departure board to see that the flight was delayed due to maintenance. Then I saw that it was delayed again because we were waiting for a flight coming in from the Bahamas. Well my flight didn't take off until about 7:30 pm. I arrived in Denver around 10:00 pm which made me miss my shuttle to the Springs. I am a diabetic and was in need of my medication so I needed to get home. I spent extra money to take a bus to downtown Denver and a grayhound bus to the springs and a cab to my home. So my trip cost my an extra $55.00 dollars I didn't have. I have always taken United but after this experience, I will never again take United."
