Pros: "Nice quiet flight"
Cons: "Crew member attitude specifically regarding passengers in the emergency rows"
Pros: "The crew was great. However I have had issues with take offs and landings with Alaska the last two times I’ve flown with them. Literally have been stuck for more than an hour on the tarmac both times."
Cons: "I think that Family’s with young children need to have their own area in the plane. I was screamed at and kicked by children for most of this flight. The extra hour on the tarmac was torture."

It was my first time flying at 54 years old and the stewardess' checked with me several times to see how I was doing and even the pilots spoke to me about my fear of flying prior to take off. All in all Alaska is great to take care of their passengers the way they did. They seemed to go the extra mile on both my flights."

Cons: "Nothing to complain about"
Pros: "Complimentary IPA was very nice."

Pros: "I liked that there was complimentary wine. I liked that I ended up with window seats on both of my flights with room for my fragile carry on luggage and space next to me. I liked the smooth landings and smooths flights. I liked the pilot pointing out and giving information on the mountain scenery."
Pros: "Comfortable"

Pros: "My flight was on time and checking in was made super easy and fast. One of the flights was a bit delayed but that was the weather so I didn't even mind because the staff was attentive."
Pros: "The crew was friendly."
Cons: "I was not allowed to use the restroom when we still had 20 minutes or so to land. As they were collecting final garbage, the restrooms were locked and I was not allowed to use them. I can understand cutting off the use of them once the flight crew is seated but they were still walking around and I really had to go. I don't recall a warning for this. If there was an announcement it was not audible over the hum of the engine. I'm very dissatisfied about that final part of my experience."
Pros: "Pilot did a great job with a lot of turbulence."
Cons: "Could not understand male flight attendant at all."
Pros: "The staff is awesome, the ride is always so comfortable"
Cons: "Not flying more often"
Pros: "Glorious leg room! Some airlines have crammed their seats so close together that even someone of average height has their knees jammed into the seat-back in front of them. Not so on Alaskan Air. I had a good 4-5 inches of space between my knees and the seat in front of me. Can't say the same for a lot of other airlines."
Pros: "An employee named Angel at Boise airport was exceptional. He was helpful and light hearted and had a good sense of humor."
Pros: "The staff was friendly and efficient"
Pros: "Airplane was very quiet for a prop plane."
Cons: "Nothing really."
Pros: "Efficient boarding and on time flight-crew was friendly and helpful."
Cons: "Being between two big men, I felt squished in the middle, so I don't know if the seats are smaller than other airlines, or just my situation, but sleeping was pretty much out of the question, as I could barely move."
Pros: "Everything was great!"
Pros: "Love Alaska and ANA. GREAT FLIGHTS."
Pros: "Great service from the crew on the flight."
Cons: "Seats didn't recline."
Cons: "The longest, bumpiest flight I have ever been on. The fasten seatbelt slight was on all but about 20 minutes of a four-and-a-half-hour flight. I know the crew is not responsible for the weather, but it did not appear that the pilot was trying very hard to find smoother air."
It would have been a perfect flight but the cabin got too cold. Too short a flight to really complain about it, though.
Delays really ruin days, excitement, the overall experience of traveling. Having inaccurate times and poor communication sucks.
The a330-900neo is an aircraft worth trying out. Comfort plus is premium select, despite the nice features, the backpack doesn’t fit well under the seat. The service to honolulu only gives snacks so make sure to eat a meal before flying the 5.5 hour flight.
As with the outbound flight, this return flight was not full - maybe 40-50%. As they started boarding they announced they located a few people the help with 'load a balance' of the aircraft. What they had done was to compress all passengers in the middle of the plane leaving no space between anyone. It is difficult to understand why everyone is required to wear Masks, then relocated to remove all space between passengers, when there was ample room to allow everyone to be seated with space between.
Thanks
Pros: "On time, clean and comfortable"
Cons: "All was excellent"
Cons: "nothing all excellent"
Pros: "Friendly cabin staff and one of the most enjoyable addresses by a captain I've ever heard (and seen - he was out in the first class area when he welcomed us)."

Pros: "Good crew, kind and hard working staff. It is so nice to have inflight messaging and that was a pleasant surprise that made the flight go quickly."
Cons: "I found the delta app to be less user friendly than the United one. I wish the in flight entertainment were in the Delta app versus downloading yet another app."
Cons: "The flight was an hour and a half late."
Cons: "After my flight was delayed for over 3 hrs - the counter clerk was rude and unhelpful. She felt it was appropriate for her to flick the customer service phone number in front of my teenage daughters. I would say avoid Delta!"
Pros: "Nothing exceptional stands out"
Cons: "Flight was not on time"
Pros: "Seating lacked the ability to recline in any way. There were no snacks or drinks whatsoever"
Cons: "The seats could recline. On a top tier airline I expect comfortable seating that declines for the price"
Pros: "see above"
Pros: "JFK to Denver the flight Attendants were once again great. Lots of entertainment choices again. The usual rough air coming into DIA."
Cons: "From JFK to Denver the seats were to close for leg room by an inch or two. The temperature was hot most of the flight."
Pros: "Standard Air France flight. My wife and I like the Airbus 380."
Cons: "The flight left two hours late. Apparently this happens a lot with this flight these days because it's an Airbus 380 coming from Paris to Dulles and turning around. The incoming flight was two hours late, so the departure was late. Our arrival in Paris was late. We made the flight, but our luggage didn't. Our return flight from Paris to Dulles was half an hour late because of people from connecting flights. We arrived about 30 minutes late, but no big deal (unless you had a connection)"
Pros: "Friendly"
Cons: "Wouldn't let us check in til right before so our family was split all over the plane"
Cons: "Seat wouldn't redline."
Pros: "Newer plane, even though it was a short flight there was a choice of movies and tv shows. Crew was very nice."

Cons: "Perhaps more than just 2 episodes of some TV programs eg Goldrush. Also more current shows."
Pros: "In a pinch they were able t"
Pros: "The kind bars"

Pros: "The crew"
Cons: "The delay"
Cons: "Flight delayed 2 hrs"
Pros: "After almost every airline cancelled. Delta still took me to where I needed to go with not one single problem. That pilot was amazing. I forget his name. But the plane didn't slide or anything during take off. Amazing."
Cons: "What was there not to like. We were a little bit late but I wasn't in a rush. I planned well ahead. Delta moved my flight from 10 a.m. to 6 a.m. and that was perfectly fine with me."
Pros: "Love the new in-cabin wi-fi, USB charging station, and menu of in-flight entertainment and resources on the individual flatscreens."
Pros: "Due to strong tailwinds, the flight arrived nearly an hour earlier."
Pros: "Space looked a bit cramped in business class but I was pleasantly surprised at the length of the flat bed and the additional foot well space once I'd reclined the seat."
Cons: "Need to fix the flickering lights in the JFK club lounge, the opposite of relaxing!"
Pros: "The seats"
Cons: "We purchased tickets together and our seats were not together when we checked in. We had one small roller bag for the two of us and we ended up having to gate check it along with 3 other people and then there was clearly enough room for it once we were boarded."
Pros: "Was initially hoping to fly a US airline but will now look for Aeromexico first. Exceeded my expectations!"
Cons: "The layover in Mexico City was a bit long and the airport was not so great"

Pros: "Boarding, checking in etc. The usual stuff, nothign spectacular."
Cons: "Seats are getting too crowded!"
Pros: "Pillow, comforter, amenity kit were all good."
Cons: "Food was acceptable, but nothing exciting or above average. Seat had some trouble reclining, but eventually worked. Entertainment unit screen had issues with acting like I was touching it when I wasn't throughout trip. Made for major annoyance watching. Delta flight 410 on Oct 1, 2017 seat 3A."
Pros: "The crew was beyond friendly and courteous. Lots of leg room."
Cons: "I was an older plane, it was louder than our flight down to Atlanta. Nothing they could do about it, but a slight annoyance."
Pros: "Able to download boarding pass into apple wallet"
Cons: "Flight was almost an hour late departing, bag is a carry on but storage too small to keep bag, then wifi didn't work the entire flight. Had to run to our connection since our layover time was taken up in Boise. If we had missed the flight, we would have been re-routed to another airport over 1 1/2 hrs away since ours closes. Next flight was not much better, oh and wifi did I t work on it also - last 3-4 delta flights I've taken have been late and didn't have working wifi - starting to think their system doesn't work at all - seriously going to take any other carrier but Delta going forward"
Pros: "Snack choices updated aircraft"
Cons: "No entertainment options"
Cons: "Flight overbooked and the gate paid no attention to how many bags were being brought onboard. Was forced to check my carry on. I hope it arrived."
Cons: "My flight got to New York so late!!!! I missed my international flight."
Pros: "The interior of this Boing 757-200 was New with a great entertainment system in the seat backs in economy, and the crew was free endlessly and attentive."
Cons: "The APU was inoperative, so the flight departure was delayed 40 minutes awaiting a ground start unit to get the engines going. It took,me some time to convince my fellow passengers that the loss of the APU was not a safety-of-flight issue. Also, a humongous passenger waddled down to our row and wedged herself into the window seat just before the doors closed. She immediately wanted to raise the seat divider, claiming that it was uncomfortable. The middle seat passenger insisted that she wanted to have it down, correctly pointing out that she had paid for a whole space. Despite the seat divider, the obese person's body oozed over and below into the middle seat during the flight, cramming the middle passenger. These folks Need to buy a second seat..."
Pros: "Friendly and informative flight attendants kept the passengers in reasonable spirit."
Cons: "Left nearly an hour late after confusion related to oversold seats and upgrades. The gate agent entered the plane multiple times. The landing was rough, the brakes were loud."
Pros: "John at Destin/Fort Walton Beach airport (VPS)was excellent! Helped us overcome some problems & get us seated. All worked fine from there."
Cons: "No problems"
Pros: "The crew was friendly and accommodating, and service was good"
Cons: "I purchased a basic economy ticket and upon checking in, my Delta app said my seat was unassigned and I had to get my boarding pass at the airport. I checked back later and the app had me as number 7 on the standby list. I called Delta (wait time 3+ hours... my flight was in 3), and then the Delta app support where I was able to get through to someone. She told me that the ticket I purchased over a month in advance did not guarantee me a seat on the plane (???). She said that if I was bumped from the flight they would reschedule me for the next morning. She was pretty rude and made it seem like I had a 50/50 shot of getting on this plane. I rushed to the airport in hopes that I would be the first from Standby there, and the gate agent told me that I was fine and would board right after first class and be assigned a seat then. Great. Once I got my seat assignment, I board to find out there is someone else sitting in my seat...... They eventually called the desk and had her moved, but it was the weirdest boarding experience I've had.. and I've flown Spirit. These planes that Delta fly's are SO OLD. Both times I have flown Delta the "turbulence" has been so bad and cold air was blowing right on my the whole flight with no option to turn it off (it wasn't from one of the vents, but from the side). Someone close to me works for Delta and I know for a fact that some of their engines blow mid-flight.. and they tell the passengers that it's turbulence.. so that doesn't make me feel very safe. I won't fly Delta again if there is another comparable option."
Pros: "Sitting in the exit row (52H) gave me lots of space and the temperature was great."
Cons: "My original flt KE018 on 03Apr17 was a different story; had adequate space, but the temperature was warm making it uncomfortable to sleep during the 13 hour flight. Unfortunately, the A-380 does not have manual overhead air vents."
Cons: "Flight attendants were a little snobby and didn't treat all passengers equally, in my humble opinion (note: I was sitting in 1st class)."
Cons: "Dirty windows. Could not see out window. I have a photo if requested. I am 6'4" the plane was small cramped and uncomfortable."
Cons: "Same as above"
Worked out okay. Flight was delayed waiting for crew to show. So glad it wasn't cancelled!
Pros: "If I could choose my seat"
Pros: "Great crew!"
Cons: "We paid for WiFi but it was not working on this flight."
Pros: "Crew was friendly and nice."
Pros: "The plane was a good size for that length of trip. Free entertainment options were excellent."
Cons: "Had to pay $80 for an upgrade to be (fairly) comfortable for the flight."
Cons: "Seat space"
Pros: "Crew was really great!"
Cons: "My bag never left Chicago so I had to wait a day to get that"
Cons: "Delayed three hours with no communication or compensation. Poor customer service"
Cons: "Person in front of me had seat reclined from take off to landing. Nobody checked. Nobody told him it had to be upright during takeoff and landing. I believe that is a safety issue. Isn’t that why the flight attendants are there?"
Pros: "Crew friendly and accommodating, even on short flight"
Cons: "Good - no complaints."
Pros: "Service was good"
Cons: "Nothing"
Pros: "Nice leg room in exit row"
Cons: "My travel companion and I encountered the most unfriendly and non respondent flight crew of all time."

Pros: "Friendly and attentive crew. On time."

Pros: "Good smooth flight and quick"
Cons: "I left my iPad in the seat pocket and they said they didn’t find it!"
Pros: "My flight was fine - I paid for a Premium Seat, which also allowed me a premium boarding position, which I highly recommend for anyone flying. The seat was comfortable, the staff was very friendly and I really liked the in-flight entertainment."
Cons: "At the DFW security post for my gate, there was NO TSA-pre. That service stops at 7pm. I would think at a major airport like DFW where American Airlines has a hub, they would make sure to staff that longer. Just getting to keep my shoes on, while having to drag all my electronics and liquids out, take my coat and belt off, etc. is not acceptable. AA should put the pressure on DFW to treat their customers better!"
Pros: "Flight was pleasant and all the crew members were courteous."
Pros: "Great pilot. Outstanding control over the plane. Arrived an hour and a half before originally forecasted three days prior."
Cons: "Flight was delayed almost two hours due to crew staffing issues."
Pros: "Flight crew very friendly."
Cons: "Everything was as expected. 1 star on entertainment as there was none. Would have liked to have been able to get 3 seats together without extra charges."
Cons: "It was nice. And boarding was good too."
Pros: "This flight is the normal nonstop from Mia to StL. The seating is tight but not completely uncomfortable."
Cons: "I just had knee replacement 4 1/2 months ago. It was difficult to fully extend my leg under the seat in front of me because the space between rows has shrunk to include more seating."
Cons: "the fly got delayed for more than 3 hours."
Cons: "There was just an announcement that the refreshments will be served shortly but there were no refreshments. Take off and landing was horrible. Flight was shaking way more than usual."
Pros: "It was easy to travel"
Cons: "Too many delays. Having to de-board after boarding."
Pros: "The middle seat was empty I had an aisle seat. That was wonderful."
Cons: "No wifi screens for books or movies but I had my iPhone."
Pros: "This was the same crew and pilot from the flight I took to LAX. His landing was so smooth, I woke up pleasantly upon landing!"
Pros: "Great staff."
Cons: "The hour delay due to maintenance and fueling."
Pros: "Why would a jet this size wobble all the way across the Atlantic! The pretzels were even stale, and they served a "pizza" that was a stale mini loaf with sauce and a little mozzarella. People were starving when breakfast was served. The thermostat fluctuated from horribly hot to freeing - for 14 hrs. The crew slammed things down on table trays, grumped, were giving harsh orders to patrons rather than gently directing them. These ladies do not enjoy their job. I am done with Delta. We were also an hour late taking off due to a door on a cargo hold not closing. I was embarrassed that our Aussie friends experienced this as their first American flight."
Cons: "Food, attitude of flight attendants, comfort of cabin. Pilot took charge of thermostat issue and kept us informed in a friendly manner regarding the status of our take off and flight progress."
Pros: "On time"
Cons: "Boarding numbers"
Cons: "Seemed to be an unnecessary delay in departing a half hour late"
Cons: "Forced to check my carry on. Took 30min for the bags to come out on the carousel. Which is why i never check my bag."
Pros: "Speedy boarding"
Cons: "Unmotivated crew, uncomfortable seats."
Pros: "very friendly staff"
Pros: "Nothing to expect from Domestic fight."
Pros: "Ordinary flight, not too chaotic for holiday weekend."
Cons: "My luggage was lost! Had to wait an entire day to recuperate my suitcases."
Pros: "Plane was ancient"
Pros: "Good"
Pros: "Entertainment, 110 plugins for devices, internet."
Cons: "only free meal option was cinnamon cookies."
Pros: "The ginger ale."
Cons: "This was my return trip with more delays due to maintenance issues of the aircraft. 10/17/16 flight 1585 was the outgoing flight delayed five hours on my departing trip. I waited at the baggage carousel 15 minutes for my bag after over an hour delay due to switching aircrafts. With a flight arriving this late in the evening with the low volume of bags checked (due to checked luggage charges), this should not be the case. Five minutes to gulp down ginger ale."
Pros: "All flights were on time Greatly enjoyed the trip"
Pros: "On time, arrived early."
Cons: "Seats too close in front of you."
Cons: "Again out of snacks and she skipped our row for drinks. Again small issues but what else are they doing?"
Pros: "Flight was on time. Plane was clean. Staff very professional."
Pros: "It took off on time and life was good."
Cons: "The Flight Attendant never gave me back my credit card."
Cons: "3 hour delay...and no voucher for the delay"
Pros: "not beat up"
Cons: "people trying to get extra carry on on"
Always a nice flight
The main flight attendant sounded annoyed and rushed every time he came on intercom. Take off was very bumpy and it continued for several Minutes and no One on crew ever acknowledged it or told us to Expect it. It was very disconcerting. Staff felt unprofessional. No cheerful goodbyes when deplaning.
My friend I was going with mom passed away the day before the trip and we had to cancel our trip. Allegiant doesn’t have a refund of any type. Frontier was my return flight and at least offered a partial credit which sucks but beats nothing.
More leg room
The crew was fantastic!
The check-in process couldn't have been worse. Besides they have no customer service to speak of, I wasn't able to purchase a 2nd checked bag prior to the trip, the app just wouldn't let me no matter what. I spent over an hour on hold waiting for a rep who wasn't able to help me. At the airport we politely asked the rep to help since we were unable. She flatly refused to do anything. When we asked to speak to a supervisor she said she was one of the most senior people there and if "We're still not happy she can give me a number to call where I can wait on hold for over 2 hours to be told the same thing I'm telling you now." Absolutely atrocious. First and definitely LAST time flying Allegiant.
My family in Arizona didn’t have a printer to print our return flight tickets, so I took a screenshot of our tickets on my phone. Apparently, when you go through security they enlarge the QR code, which makes it blurry, so it can’t be scanned. We had to go back to the check in desk and pay $5 for each ticket to be printed. Lesson learned, print out all flight tickets before you leave.
Pros: "All around terrible Airline. Canceled our flight at the last minute, all the while telling us they had it under control and were going to fly. Made us sleep in the airport all night, re check in, bags and all at 4 AM, without any compensation at all. Don't fly this Airline."
Cons: "All around terrible Airline. Canceled our flight at the last minute, all the while telling us they had it under control and were going to fly. Made us sleep in the airport all night, re check in, bags and all at 4 AM, without any compensation at all. Don't fly this Airline."
Cons: "Communication with the customers"
Pros: "The crew was amazing, super helpful, very friendly and understanding when it came to social distancing."
Cons: "The seats are not the most comfortable, but the price is right."
Cons: "Everything"
Cons: "It's a low cost, no frills flight option. But we left and landed on-time and that's what I wanted."
Cons: "I love the changes that have taken place. I last flew with them 5 years ago and vowed too never fly with them again. Times have changed and they are a great Airline!!!"
Cons: "Temp in the cabin was a little chilly but not totally uncomfortable"
Cons: "I tried to cancel this trip but was told I would have to pay more in order to receive a refund. Very disappointed customer as I have traveled with Allegiant many times and the one time I try to cancel my flight, I’m told I have to pay a fee which was more expensive than the actual price of the ticket. Waste of money."
Pros: "Cost"
Cons: "OMG, miffed and aggravated right now!! Currently on Allegiant Flight 1355. PIE to CVG A non-eating flight. These POSs MFers decide to have a friggen pizza party in the middle of the flight"
Cons: "The air pressure in the cabin was awful. My ears hurt & it gave me sharp pains in my head. Even typical yawning & blowing nose did not help."
Pros: "Half empty and on time"
Pros: "Crew unfriendly, unprofessional, and not courteous,"
Pros: "Cool"
Cons: "Good"
Pros: "The plane was clean and crew was very friendly."
Cons: "Delayed departure with no explanation. Other passengers clogged up the overhead bins with small bags, purses and containers of to-go food. Causing me to place my carry on in an overhead bin multiple aisles behind my seat which made for a cluster trying to board and de board."
Pros: "Late"
Cons: "Be on time"
Pros: "The actual flight was comfortable and the crew was good."
Cons: "Flight time was pushed back a few weeks ago. Slow boarding process so we landed about 30 min late."
Pros: "The crew was friendly and the price was low."
Cons: "Communication during our delay."
Cons: "it was very hard to hear the stewardess"
Pros: "The plane didnt crash :) Friendly attendants."
Cons: "NO WIFI. Flights are delayed often, what looked like a brand spanking new plane had the most uncomfortable seats ever, felt like sitting on wood in the exit row. You get what you pay for though."
Pros: "the staff was nice."
Cons: "the soda can was 2$ and for a rum and coke 20$, the plane was uncomfortable"
Pros: "It was great"
Pros: "Affordable but no free water or snax"
Cons: "Cheap feeling seat. Thin plastic shells packed tightly together. But hey- its cheap!"
Pros: "Even though the flight was delayed by more than 2 hours, we were able to make it home."
Cons: "Started with constant delays. Flight ended up leaving around 8:30 when the flight was supposed to leave at 5:59. Once boarded there were no snacks, no liquor and only a few options to drink. The flight attendant was mumbling and kept on messing up what he was supposed to say the entire flight."
Pros: "Friendly staff!!"
Cons: "Hour delay on flight"
Pros: "Passengers were fun"
Cons: "Need entertainment"
Pros: "Standard no frills airline"
Cons: "No room for overhead bags near my seat. I paid $25 to sit up front and $35 for a carry on. I paid extra with the goal of deplaining first. Crew refused to allow me to stow the bags in the front bin, had to place it 10 rows back. If I didn’t run to my gags as soon as Wen landed would have been the last to deplane. If allegiant is going to charge so much for carry on, they need to find a way so front passengers are not squeezed out like this."
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: "From entering the airport, gate, and plane- nothing is more pleasant and efficient than Allegiant flights. I was able to attend my grandsons bday and back by start of the next week- round trip at REASONBLE prices! Thank you."
Cons: "I am ok with it but the walk way was so filthy on my return trip. I know plane was late and we boarded late... but a really quick vacuum would have taken only a few minutes. I realize it was messy from cl"
Pros: "The staff is always helpful and flights are comfortable."
Cons: "Allegiant needs to put more than just school bus seats in their aircraft."
Pros: "The view through a milkey-filmed window."
Cons: "Airplane would have been nicer and lighter if the 4 attendants would have cleaned it."
Pros: "Very cheap ticket Non stop flight to HTS with excellent service. Eat before the flight. It is a short flight but if needed bring your snack... airports near big cities..."
Pros: "No frills inexprnsive"
Cons: "No services"
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: "Nothing"
Cons: "Not to be helped, but was a bit bumpy."
Pros: "I like the flight. It was on time"
Cons: "Nothing"
Pros: "At least I arrived to Oakland eventually. A one hour flight turned into a 7 hour wait and flight"
Cons: "7 hours from Vegas to Oakland. I could have driven. I deserve a reufind voucher"
Pros: "The crew was very friendly"
Cons: "The flight was delayed 2 hours. The plane was freezing the entire flight. Apparently, the crew tried to get the pilot to turn down the air, but it never happened. I hate how Allegiant nickel and dimes you. Not even a cup of water is free."
Pros: "The flight was on time and the staff were courteous."
Pros: "Flight smooth"
Cons: "Extra costs"

Pros: "Excellent direct flight at good price"
Cons: "Flight 339 not listed on TV monitors at Boise airport"
Pros: "Safe trip. Kept informed of short delay. Thank you."
Cons: "NA"
Cons: "The bathroom on the flight from Denver to Santa Barbara was the WORST EVER! I doubt it has ever been cleaned and the poor people that had seats near or at the rear of the plane should have been refunded their money having been subjected to the smell of an “indoor outhouse!” Shameful!!"
Pros: "The range of 'free' food and beverages (including beer, wine, and liquor was phenomenal, and the functionality of the 777 touch-screen was outstanding. Seating was also more comfortable than comparable flights on AA."
Pros: "Nothing, absolutely horrible. This is why I fly Southwest and Alaska Airlines as much as possible."
Cons: "Everything. Mechanical delay missed connection, arrived at gate to see plane being pushed off due to delay. They couldn't have waited 5 minutes? Multiple people missed their connecting flights within minutes. They kept us on the plane in Boise then deplaned and re-boarded. No coffee on flight."
Pros: "The crew were friendly & efficient, the flights were on time, & the gate staff kept us well informed of any changes."
Pros: "Good crew, good and safe flight. Thank you!"
Cons: "Nothing."
Pros: "Yes, crew were great, seat was okay"
Cons: "Have life vests on board for the crew, was delayed over 2 1/2 hours on run way!"
Pros: "Poor customer service and not understanding."
Cons: "Don’t now it’s not the company’s fault it’s just the representative that I spoke to. I don’t know how many times I could explain my situation, and my English is not poor and I thought I was explaining myself clearly. Best think I could do is just say forget it I’ll take my $ 430 dollar last."
Cons: "2 hour maintenance delay"
Cons: "More leg room"
Pros: "Safe flight. Also, I was offered a different flight from Boise, ID, in order to make my connection in San Francisco. Thank you!"

Pros: "It didn’t happen."
Cons: "Because of the late plane and possible missed connection, I was re-booked for the next day without any compensation."
Pros: "I travel a lot. All was fairly normal."
Cons: "Entertainment didn’t work. Woman next to me sat cross legged and the bottom of her foot as resting on me. When I politely asked that she not out the bottom of her dirt against me she swore at me and was confrontational and crazy. Flight attendants did nothing"
Pros: "Glad they had a direct flight."
Cons: "The seats didn't offer much room."
Pros: "It’s my longest trip ever due to United"
Cons: "Poor communication between the airline and I, I don’t like the service"
Pros: "I found the reason for being late to be questionable They said heavy snow but as i flew in i looked out the window and saw all roads nicely cleared That does not happen in 3 hours"
Cons: "They did not get my liggage to the connecting flight And here i am in Ukraine with no winter clothes at 7 below 3 days later"
Pros: "Friendly crew."
Cons: "Had a mechanical issue we were told didn't need fixed to fly the plane. Took 1 hour and 20 minutes to complete safety checklist so we could take off. We missed our connecting flight to Cancun."

Cons: "N/A..............................................,"
Pros: "the crew was very friendly and the flight was smooth"

Pros: "More fights to choose"
Cons: "Could not choose the seat at the time booking"
Pros: "That we got to Little Rock early"
Cons: "I had ordered ginger rail and the lady brought me a Diet Coke I told her I don't like Diet Coke because I don't drink Coke and she said I thought that's what you want it now you have to hold onto it until they come back and pick up the trash and she never brought me the ginger rail to drink she walked away and I never drank nothing on the flight back to Little Rock that lady was so rude"
Cons: "Food, like all airlines, is so lacking even though airlines are making record profits while lessening service (crowded, fewer flights, baggage fees, etc)."
Pros: "Great staff and everything on time"
Pros: "Nothing"
Cons: "That a bunch of travelers including myself missed our connecting flight in Chicago after united chamged our arrival gate but didn't have any crew to man the jet way. We sat for 20 mins right in front of our gate. From 1 pm to 10 on my flight to Asheville from Chicago was delayed many many times waiting for our airplane to arrive. Upsetting that we missed our connection due to United's poor planning, they didn't hold our connecting flight for us but we had to wait all night for other flights."
Pros: "The travel agent, Tim, in STL worked very hard to get us on a flight."
Cons: "After a cancelled flight, two delays and lost luggage (that we did not receive for two days after arrival) on the way to Boise, we've now been cancelled on the way home to St. Louis. The first cancellation was due to weather. The two delays were due to late crew and refueling issues. Today's cancellation was due to maintenance. Embarassing. I travel often and can guarantee I will never fly United again."
Pros: "Fast and smooth"
Pros: "we left right on time. It was a smooth flight and a nice aircraft. did not use entertainment so no comment there but was a good experience overall."
Pros: "Attendants were nice."
Cons: "I booked the comfort economy seating that I normally do with Delta. With their additional cost you get a larger seating area, free in-flight movies, reserved compartment space for your carry on and a free drink. No such thing with United. They did try to have movies through their app, but it wouldn't play long enough to allow you to watch."
Cons: "The crew was terrible. We sat on the Tarmac for over an hour, very limited information. Flight attendants were asked for ETA several times in flight and never gave any information to passengers. At one point saw them taking selfies in the front of the plane service area. Worst service I've ever had in a flight"
Cons: "The flight attendants were disrespectful to not only me but to other passengers. They were not attentive! The plane was dirty."

Pros: "They let us get off the plane"
Cons: "No complaints"
Pros: "Hate attendant went above and beyond to help me upon return from abroad."
Pros: "prompt emails and text messages with the back up plan"
Cons: "Missed connecting flight because flight delayed takeoff from home due to SFO problems. Sat on tarmac for an hour or more, finally took off but missed connecting flight mid afternoon and no other acceptable flights until 11 pm getting into Fort Lauderdale at 730 am. (originally was supposed to be getting to Fort Lauderdale at 10 pm). Also, the aisle seats on the plane had a narrower underseat space that my little boxy carryon wouldn't fit into--and it usually fits under any underseat storage...Luckily the passenger in the middle was willing to swap places."
Cons: "Worst ever Can you credit my credit card for a full refund"
Pros: "Flight to Austin was just fine."
Cons: "My flight back to bosie from San Francisco they changed the gate I didn't hear the change and missed my flight. I didn't get back to bosie until the next day."
Pros: "Nothing"
Cons: "United are the most rudest phone people on the phone to deal with and if it's there fault they never want to comp u last time I fly with united"
Pros: "Flight was on time"
Cons: "That u load the plane assistance backard,loading goes much faster if you start @the back of the plane,& myself I carry only a shoulder bag only ,all the time. U put me @ the back of the plane 90% of the time which means I have to wait for the people that are moving their whole house,making me miss my schedule, I have to spend night @ airport for next schedule."
Cons: "no inflight entertainment."
Cons: "The delays and plane changes started the night before, and continued throughout the day. All were listed as "Operations issues". When I arrived for the flight, it was delayed about 30 min. When boarding time approached, another delay and no plane in sight. When the other plane finally arrived almost an hour after our scheduled departure, we were told it would be a quick boarding. People started waiting in line, but no passengers were getting off the arrival. After a short time, the announced they were having problems with the luggage. After about 30 min of waiting, the flight was finally cancelled due to "weather", even though you could see other flights taking off. I'm sure it had nothing to do with our arrival airport being closed for the night by the time we would have arrived. Thanks United for the $55 cab ride. Every trip in the last year on United has either had a delayed or cancelled flight!"
Pros: "I arrived on time."
Cons: "Flight was ok. I was disturbed by the rudeness of flight attendant toward a service dog. This dog was the owners eyes and she seemed disgusted it was there. We had to let her know in front of other passengers so she would be put on the spot and change her attitude."
Pros: "The plane took off and landed on time"
Cons: "The plane was old and some seats had been replaced but not all so the older seats were uncomfortable and worn."
Pros: "Luckily the crew on this flight was friendly and courteous, unlike United flights I had 2 months ago, because everything else was pretty horrible."
Cons: "First, we were delayed over 2 hours for maintenance problems. Second the plane was cramped and the seats were hard as park benches. Third, this flight had zero entertainment options although they advertised for it in the seat back propaganda. Fourth, the cabin noise from the engines, once they got them started, was so loud that even my noise canceling headphones could not prevent me from getting a headache. At least we got there safely, eventually."
