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

Pros: "Nothing in particular"
Cons: "Outlet did not work"

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."

Pros: "Same"
Cons: "Same"

Cons: "3rd flight in two weeks suck sitting next to a morbidly obese person. They should be forced to purchase two seats."

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: "Pilots that did show up were pleasant and made the best of the situation."
Cons: "No scheduled pilots for this flight. Pilots that did arrive had their schedule rearranged---they showed up to work thinking they were flying to Seattle. They were asked to step in to fly to Denver instead---20 minutes after our scheduled takeoff time; not horribly late, but seemingly disorganized, which leads to all kinds of thoughts about AA overall competence."

Cons: "Food"

Cons: "The gates closed early and I missed this flight! Horrible service, never flying American again."

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."

Cons: "Everything. Had to sleep overnight in airport and was late coming home."

Pros: "Staff was great!"
Cons: "Seats were really uncomfortable up and reclined. Overhead baggage was full by the time I boarded and there was no enforcement of the carry-on baggage sizes... This needs to be addressed and contributed to our lack of comfort, noting this was the last leg of an 18 hour journey. My body still hurts today after a good nights sleep."

Cons: "No tvs!!"

Cons: "the new seats are awful"

Pros: "Tv and power outlets"
Cons: "This one attendant didn't get her name but was very cold to me"

Cons: "Long delay"

Pros: "More improved than the last trip I took with AA to Denver. Efficient boarding."

Pros: "Everything"

Cons: "Uncomfortable seats Crying child"

Pros: "We were able to get to Denver"
Cons: "Jammed in like sardines, rude flight staff, extremely hot aircraft for November"

Cons: "Unexplained delay in leaving but only arrived about 10 min later than scheduled. Took an hour from pulling into the gate for bags to arrive though which caused me to miss my shuttle. Never had to wait more than 15 min for any other airline at DIA."

Pros: "Flight not entirely sold out. So they let my 14 month grandson have an empty seat between my daughter and I. That was a great gift since he doesn't sleep and is jumping and crawling all over the place. And I'm sure the other passengers were breathing sighs of relief!! Also super smooth landing and nice flight attendants."
Cons: "Flying with an active 14 month old toddler boy and of his "stuff" is nothing less than anxiety provoking. Not much the airline can do.."

Pros: "The departure time. This left enough time to get to the airport and go through security without rushing!"
Cons: "Sitting in the middle Paying for luggage ( I wish Southwest flew out of ORD)"

Cons: "When your on your honeymoon it sure would be nice to have a seat next to my husband like we requested."

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

Pros: "Very friendly staff"

Cons: "The service was terrible, 4 hour traveling and not food."

Pros: "the entertainment was good. Loved the free wifi. Loved the complimentary drinks"
Cons: "The flight took 45 mins to depart after the scheduled time. The flight attendance were super rude. The pilot was not easy on the landing or how he took off. First flight ive ever felt sick on."

Pros: "A free airline ticket!!"
Cons: "I did not like the fact that American Airlines cancelled my 17 Yr old neice's flight from Dallas to Denver over a thing called "timed-out". And had her sleep in a room with a cott instead of a hotel room. And the fact that we as customers pay good money for tickets only to be subject to the airlines way of business. It is absolutely unacceptable!"

Pros: "Amazing Crew! Fast flight!"
Cons: "Security"

Pros: "Crew was very helpful Everything was on time"
Cons: "Very bumpy ride (not anyone's fault) Very uncomfortable seats"

Pros: "The passengers were spaced out, so we could actually social distance."
Cons: "Not all passengers wore masks. During a contagious pandemic. What the actual hell? Also, the tray tables are too small to use for anything, and we didn’t even get a free drink. Water and soda are so cheap, it’s absurd. I’d never take Allegiant again if they weren’t basically the only airline operating out of my town’s small airport."

Cons: "Great price. Wonderful flight. Seats are so close knees touched the whole flight."

Pros: "Boarding was a breeze"

Cons: "Roomy aisles and seats, on time boarding and flight. Great job!"

Pros: "Crew was friendly and accommodating."
Cons: "?"

Pros: "Fast boarding, early arrival"
Cons: "Snack offerings"

Cons: "The landing. the approach was so rough. I've flown 6 times this year. And that was the roughest approach ever"

Pros: "The crew"
Cons: "Very bumpy from take off thru first half of flight, though this wasn’t anyone from allegiant’s fault, just scary!"

Pros: "Fantastic! Smooth sailing!"

Pros: "Cool"
Cons: "Good"

Pros: "There was nothing outstanding really"
Cons: "It’s a low cost airline, so expectations are very low. Plane was very dirty because it just keeps on hopping back and forth without any cleaning service it seems"

Pros: "Crew food. Seat small little leg room."
Cons: "Plane on time. More leg room."

Pros: "Enjoyed isle seat."
Cons: "Wider seats."

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 the best on any flight I have been on. Love their jokes."

Pros: "Great crew. Good on-time flight (early, actually). Smooth boarding."
Cons: "Standard no-frills gripes. Seat is tolerable but basic, no recline. No power, zero inflight entertainment, etc etc. They won't even give you a sip of water for free, which is just absurd in my opinion. They did give me a free cup of ice... so I guess ice + time = free water..."

Cons: "Unfriendly Flight attendants"

Pros: "Crew was very pleasant and professional"

Cons: "Nothing"

Pros: "Nothing"
Cons: "Super rude personelle"

Pros: "Efficient, direct flight, outstanding price, quick boarding, left late but arrived on time"
Cons: "Nothing. I did not try food or entertainment on this flight."

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."

Cons: "Squished and smelly but good value overall and good crew"

Cons: "Delayed flight"

Cons: "Lousy airline. Left gate late and unfriendly crew. Wanted to charge me for carry on."

Pros: "Flight attendants were nice."
Cons: "There was no one working at the counter when we arrived at the airport and there was already a sizable line. We waited about 10 minutes before anyone showed up to assist customers. Not sure what was up with that. Very uncomfortable seats and crowded seating on plane which is typical these days everything else went fine. Flight left and arrived on time."

Pros: "Crew was very friendly, very polite unlike the United flights I have taken. I was told the space would be uncomfortable but it was absolutely fine for the short flight."
Cons: "No beverage service. Not even water is offered."

Pros: "To be honest nothing"
Cons: "Missed flight any no one was willing to help us pure BS"

Pros: "Made it home safely."
Cons: "Waited on tarmac 2.5 hrs. Then plane delayed 10 hours. Then waited on tarmac 2 more hours. Horrible first experience flying with Allegiant."

Cons: "4 hours late. No explanation. I have flown Allegiant 3 times. Late twice."

Pros: "It was exceervice"

Pros: "For a “no frills” airline I like the modern aircraft, professional and friendly crew and on time departure and arrival. The flight is too short for entertainment or food service but the snacks and drinks for sale are varied and acceptably priced."

Pros: "Friendly Crew. Staff did expedite our checking bags to make our flight when we asked about our flight that started boarding early and made sure our bags made the flight. Excellent pilots, trip went seamless from wheels up to wheels down."
Cons: "Boarding started 30 minutes earlier than first notified as, Long lines to check bags."

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: "Both ways were good flights. The return flight however was delayed. We did enjoy buying some tickets from a lady named Valerie in Des Moines who also later had to come on the plane and remove an intoxicated woman. She made everything so easy and simple and enjoyable. And we especially enjoyed the treatment that we received as my husband is a veteran. Thank you so much for that."

Pros: "My wife said that this was the smoothest airplane ride she had ever had."
Cons: "The first lady at the check in desk told us the wrong gate. We wound up taking a tram to another terminal, found out that we were in the wrong place, and then made it back just in time to board with a few minutes to spare. Anyway, the airline itself was o.k. and next time I'll check the arrival/departure board. Since we were traveling with only a carry on, it was a good price after all the "frills" were added (pay for carry on, pay to select seat). we still had a price lower than any other airline. So all in all, once we got on the plane it was a pleasant experience."

Cons: "All of the hidden fees. I was initially charged more than $200 over the price I was quoted on Kayak.com and then had to pay an extra $45 to bring 1 carry-on each. I do not plan to use Kayak.com again for these reasons and will not recommend this site to anyone"

Pros: "Cost of tickets, airport locations-and more convenient travel utilizing smaller airports."
Cons: "Baggage fees are outrageous, no complimentary amenities or refreshments. Flight attendants were rude in asking parties to return to assigned seats, while there were several completely open rows towards the back, (no obvious or explained reason aside from "assigned ticket seats" that they should remain empty. Families or companions could have traveled together- seemed unnecessary to prevent this, only gain noticed was Flight attendants satisfaction at denying seat relocation."

Pros: "Last week I flew to Florida on this airline. I quickly wrote a stellar review because the flight crew was sincere, nice and kind. Apparently, that is against policy and on this flight there was no hint of that nice attitude. No frills, no courtesy, just transportation."

Pros: "Great service and very clean plane. Staff did everything to accommodate everyone's needs."
Cons: "There was a lot more turnulance than expected which could have made for our shaky landing but the pilot did a great job regardless."

Cons: "2 hour delay, plus a filthy plane with bloody toilet seat, completely bathroom fail."

Pros: "The fight"
Cons: "Security"

Pros: "I arrived less then 5 hours late"
Cons: "No free peanuts, no free pritzells,no tv show, no movie"

Pros: "Evertything was on schedule ."

Cons: "Seats are ridiculously close, hard and incredibly uncomfortable. Round trip both flights delayed. First and last time"

Pros: "The price, found a round trip from Albuquerque to Austin 3 weeks ahead for 74$. I couldn't believe it"

Pros: "friendly crew clean plane, speedy service"

Cons: "The flight was delayed 8 hours"

Cons: "Wish the seats were a bit more comfortable on frontier. And had to pay for carry ons. Will never ride frontier again."

Cons: "Everything was excellent"

Pros: "Easy to board and check in, good price"

Cons: "Nothing"

Pros: "On time..nice staff"

Pros: "It's seems like no one cares about passengers in this airline.... Rude services"

Pros: "I liked the fact that I had a window seat... at the way back. Also that I was at least offered snacks, or whatever was left because they ran out."
Cons: "They ran out of meals and snacks, both paid and free. We all pay a price, yet seats and class determine whether you will get your moneys worth. I guess the point is that I at least made it home."

Cons: "Little more time between flights would be nice"

Pros: "New illy coffee is really good"

Pros: "New plane"
Cons: "The way you bord the plane"

Pros: "Convenient, cheap, best route"
Cons: "Incredibly uncomfortable seats on the express jets - we joked that we need to bring stadium cushions next time. For a full day of traveling, I would consider a more expensive route with another airline than tolerating the hard seating they offer."

Cons: "The airplane was freezing, and I'm 23 years old and very used to flying."

Pros: "All went well. Pleasant attendants."

Pros: "It was inexpensive"

Pros: "that they warned me the plane was extra small and checked my carry-on at the gate for free."
Cons: "that they didn't really advertise how small of a plane I would be flying. I guess you're supposed to research every plane before purchasing tickets now."

Cons: "My TSA Precheck status would not print on the boarding pass. My number was in the system. I've used it multiple times flying UAL."

Pros: "Time and confort"

Pros: "Agents checking baggage were unbelievably slow. Good thing there wasn't a long line."

Pros: "Fast getting my seat assignment. The guy at the gate counter was nice and courteous."
Cons: "TSA line was ridiculously long. Only one checkpoint open for the entire terminal."

Cons: "Could not get seat assignment 24 hrs in advance. Website said see desk. Phone call to United said pay more $ get a seat. Had to check in twice, once with bags...still no seat...wait in line again at gate for seat."

Pros: "Very friendly staff"
Cons: "I got stuck in the back of the plane and I did not realize the seats had even less room back there."

Pros: "Nothing"
Cons: "You guys robbed me"

Cons: "No cash food and beverage"

Pros: "That trip was great to Housto!"

Pros: "I liked that 1 out of our four flights had more room & personal tvs."
Cons: "I did not like the fact that out of our four flights three were not too comfortable... & no tvs on three out of four"

Pros: "On time and friendly"

Pros: "None"
Cons: "No refund for my resheduling of flght. I has a valid reason with a valid documentaion"

Pros: "WiFi was awesome"
Cons: "Wish the TV preview was continuous & pay for movies but watch regular TV work no charge"

Pros: "Getting home"
Cons: "Delays delays delays"

Pros: "Hassle free booking(no hidden fees) comfortable seats which for me being 6foot6 isn't always the case. And the free selection on the united airlines app was an awesome bonus"

Cons: "The cold air near floor"

Cons: "My TSA wasn't tagged to my ticket"

Pros: "Got to check 2 carry on pieces for free because too many people had carry on bags. We had paid to check one bag and would have to pick it up anyway, so checking extra pieces was not a problem and actually was very much appreciated."
Cons: "15 minutes late in taking off because an airline associate failed to close out a screen on the computer. It took too long to figure out the problem."

Cons: "Three gate changes prior to departure"

Cons: "Seating on this aircraft is poor at best!"

Pros: "Quick and on time"
Cons: "Personnel"

Pros: "Turn off the damn screen in front of me. Programs are insulting'tv"
Cons: "Tv screen"

Cons: "Three of the four flights were delayed. It seems that this is business as usual for United."

Pros: "On time!"
Cons: "No jetway, long walk to the next gate and then the same long walk back down to board the plane for the second leg of the trip."

Cons: "Way to expensive"

Cons: "It was an enjoyable trip, no complaints whatsoever."

Pros: "Boarding on time and easy Seats super comfy Tv was great"
Cons: "Staff not attentive or friendly Not many food options"
