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

Cons: "Seat cushions are too thin."

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."

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

Pros: "It was a short flight. The overhead bins weren't overloaded."
Cons: "Boarding was a hassle. The flight was too crowded. The food was non-existent.. Seats were uncomfortable."

Cons: "Two out of three USB ports would not hold cable on my premium seat row. Would not recommend if something as simple as USB port inoperable is not handled by cabin service or maintenance. We paid additional fees for this seating and couldn’t keep device charged. Very disappointing"

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."

Cons: "No legroom unless you pay more for it."

Pros: "How friendly and professional"

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

Pros: "Everything"

Cons: "Nada"

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

Pros: "I enjoyed flying Alaska Airlines"
Cons: "Nothing"

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"

Cons: "Service was amazing"

Pros: "Great service and very organized."

Pros: "price"
Cons: "delayed"

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: "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: "My favorite airline to travel from Denver to Puerto Rico, round trip, and in Atlanta I will make the stopover, I also feel so safer to travel with my cat ... they are the best airline in everything"
Cons: "Let people who travel with pets earn extra points for taking them with Delta"

Pros: "Delta is doing a great job keeping everything calm and clean during this pandemic!"

Cons: "Nothing all excellent"

Cons: "It was great! Nice job Delta !"

Cons: "Wouldn’t change a thing! I don’t always fly! But when I do!! I fly delta!!"

Pros: "I always have a consistently good experience on Delta. Everything was great."

Pros: "Everything ok. I was hoping to buy food but glad to see almonds as one of the free snacks. Delta seems to be upping its game a bit lately."
Cons: "No US carrier seems able to master smooth boarding without standing waits."

Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"

Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."

Cons: "1.5 hour delay...no reason given!"

Cons: "Flight was delayed and completely packed so our family could not get seats together"

Pros: "Love the fact that the head rests move to support your head better."

Pros: "The male crew member was excellent. He was responsive and speedy with trying to find a solution. He gave me a few flyer miles for my trouble and was empathetic, which is rare."
Cons: "The tv/monitor didn’t work so there wasn’t any entertainment for the majority of the flight."

Cons: "No meal option and my video screen volume did not work"

Pros: "Boarding was easy."
Cons: "I am 6' 1" tall and weigh 220, so not out of the ordinary and I felt like I was stuffed into a sardine can."

Cons: "Better screens for in-flight movies. More legroom or upgrade options."

Pros: "Inflight experience was fine. TVs didn’t work but Flight attendants are friendly on Delta, cramped seating - but not unlike other airlines."
Cons: "Regular fare seat assignment not available prior to gate . Airport concourse F - poor - limited services. Customer Service seemed uninterested and unable to provide service both on phone and at gate. I’m a frequent United flyer & today’s Delta service experience made me more loyal to UA."

Pros: "Early and middle seat was open!"
Cons: "Coffee tasted like fish. :("

Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."
Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."

Cons: "Very little leg room."

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: "Love the built in tv’s with free entertainment."
Cons: "The plane got delayed on the runway and the shut the engines off so the plane got super hot, but even after we got up in the air it never cooled down. Normally I’m freezing on flights, but I just sat sweating this whole flight. It was terrible."

Pros: "Delta....ticket counter...gate agents....flight attendants....pilots...amazing customer service with a smile! Very attentive and everyone thanked me ( and other passengers as well for flying with Delta."
Cons: "Nothing negative to say!"

Pros: "The seats had plenty of leg room and the crew was was very kind."
Cons: "My seat was uncomfortable and I was seated in the only row of the aircraft without entertainment for a four hour flight. Then on top of that the passenger next to me removed his shoes and you could smell his feet from a mile away but the flight attendants never requested for him to replace his shoes."

Pros: "Everyone who has a kid knows how challenging certain things can be in a flight and for me the combination of a night flight interrupting my baby’sschedule + a full flight it equalized disaster. My daughter could not get comfortable for the love of life and I just felt horrible and frustrated and what sucked most was the 9 year old and her obese father siting in our row that kept giving us weird looks."
Cons: "There’s NO room in planes between seats. It’s 2018 and new planes must be done ASAP to accommodate people better. I’m 5’1” and 110 lbs but adding my 25lb daughter siting in my lap before she turns 2 is absurd to expect that it will be comfortable whatsoever for us or the people breathing next to us. Please DELTA, lead by example and make sure your planes are designed with more room in between and around the seats. In my opinion, every seat should be first class."

Pros: "I usually have had great experiences with Delta. The meal selection was limited. By the time they made it up to my seat they had run out of what we wanted. Also, the entertainment system at my seat and my husbands wasn’t working well. One of the bathrooms had a cabinets Tvst oliiiooooiiooooioiooiiiooiio"

Pros: "The staff really helped me out getting on standby so that I didn't have to wait for a 9 hour layover. Overall great experience and great staff."

Pros: "In a pinch they were able t"

Pros: "Great in every way"

Pros: "Excellent piloting and cabin crew."

Pros: "It got me home, eventually."
Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"

Cons: "Check in lines were crazy long"

Cons: "My daughter was stuck in SLC for 5 hours because there 1 cancelled flight and 1 delayed flight. It was very upsetting not knowing when she going to arrive in Denver."

Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"

Pros: "The entertainment unit allowed me to watch the Denver Broncos game live which helped lessen the delayed departure and uncomfortable seating."
Cons: "Uncomfortable seating....too crowded!! We had a delayed departure by 30-40 minutes because of a computer download issue. Too many folks carrying carry-ons delayed boarding. I wish folks were not encouraged to go that route but to check baggage. This time of year gets even tougher with folks carrying Christmas presents and over sized personal items. Ugh. Not fun to travel this time of year."

Pros: "really helpful and friendly service and nice seats."

Cons: "We left late, it was delayed then maintenance issues. Twice. Seating was very tight and uncomfortable, no movies or entertainment at all. U.S. flights are the worst. Even on short flights with aeromexico outside the U.S. you get movies and food. Zero stars for comfort, food and entertainment."

Pros: "The plane, crew was clean, newer and had TV's in the backrests. Remember to bring headphones! Seats are tight, but the crew was friendly and may the flight experience positive."

Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"

Cons: "Excellent service excellent pilot"

Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"

Pros: "Free in flight entertainment"
Cons: "One of my bags went to Santa Fe"

Cons: "I'm tired of Delta making it IMPOSSIBLE to experience benefits of my loyalty. I flew literally AROUND the world in the past 6 months and it STILL doesn't qualify me for anything more than Silver elite? Seriously? When you use a voucher because of their error to lower your ticket price, but still pay cash for it, why does that then automatically exclude you from upgrades? Poor customer loyalty, in fact, non-existent these days."

Pros: "Early arrival. And service"
Cons: "I was assigned very last seat and there is no reclining option."

Cons: "long wait and delayed flight"

Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"

Pros: "One male attendant from the first class cabin - super sweet and attentive to our needs even tho we're not seating in the premium cabin"
Cons: "Junior attendants in economy comfort seat - so lazy and whiny!"

Pros: "Very professional and caring."

Cons: "Website is still slow to update trip delays, not a problem today though!"

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

Pros: "direct flight"
Cons: "airport hassles"

Cons: "The boarding process. And how the flight attendants speak to the customers; I found a bit abrasive and insensitive for no real reason."

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."

Cons: "Allegiant plays games with seating to try to milk more money from passengers."

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

Cons: "Bad turbulence throughout the entire flight. Hot temperature during majority of flight."

Pros: "the crew was very welcoming. and the boarding process was fast."
Cons: "the seats are not comfortable. however I can understand because of the price."

Cons: "No hot coffee on 7:40am flight. Not right."

Pros: "When you land at Concord you are right near the parking lot!!!"

Pros: "Crew was nice and the plane was clean."
Cons: "Bring snacks and drinks because they charge for everything."

Pros: "Boarding is always a pleasure out of Provo, with no security wait and a pleasant crew. The plane we took was a newer model, and is similar to many Fronteir and economy Delta planes. Unfortunately that means that even a short one-hour flight leaves pains."
Cons: "Our ride was very turbulent, whether that’s due to weather or pioloting I’m not sure. Either way it would have been wonderful to have a free cup of water. Sat for de-icing for about 20 minutes before takeoff."

Pros: "The staff was friendly"
Cons: "The flight was delayed multiple times, the directions on having boarding passes on the app or printed prior were not given so found that our last minute to avoid paying the front desk clerk $5.00. The flight landed 5 hours later than scheduled which is completely unacceptable."

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

Pros: "Price and direct flights to popular destinations."
Cons: "No frills. Charging $5 for a printed boarding pass seems a bit excessive"

Cons: "This was the first flight if the day and the plane floors were fithly. It look as though they have not been vacuumed in a few days!!!"

Pros: "Great airport for getting to Florida. Good prices"

Pros: "Nothing."
Cons: "The flight was delayed by hours, with no explanation given. It was coming from Florida, with no bad weather in between. It caused us to arrive at 1 am."

Cons: "Seats are hard"

Pros: "We were delayed on takeoff, but pilot made up a lot of the time I. air"

Pros: "The flight was delayed for almost 4 hrs, but the staff was excellent. From the check-in agent, the gate agent, the flight attendants and pilots - everybody was upbeat and helpful."
Cons: "Just the continual delays, but the mobile notices were so helpful in not coming to the airport for a delayed flight. As always, the fact that the seats don’t recline makes the trip more uncomfortable."

Pros: "Pretty empty flight so we were able to change seats. Good thing because my family wasn’t sitting together-$12 to pick or change seats ahead of time. Just be prepared and knowledgeable about this airline and other budget airlines and you will be satisfied. - pay for bags in advance, Try to weigh your checked bags before the airport, Bring snacks or drink on flight - otherwise you have to pay for it. Trenton and punta gorda airports are small, you have to walk to the plane. I love the small airports, no lines , easy parking!"
Cons: "Seats aren’t that comfortable and don’t recline even a bit, tray table is small."

Cons: "The seating is terrible. Everyone is like sardines packed away."

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: "Great airfare, great staff, etc. Cant help that the passengers are idiots ! Love this place."

Pros: "No Delays All went smooth & arrived early!"

Pros: "On time and very efficient"

Cons: "It was raining when we landed and we were told the guy didn't want to come out in the rain to open the door so we were stuck on the plane for a while. Being Florida, it rains. If it's your job to pen a plane door, I would think it's reasonable you do it in the rain sometimes. Then up to the passengers on board whether or not they want to get out of the plane when it's raining."

Pros: "The staff was nice, kind of, but also unprofessional at time."
Cons: "My flights were both fine but the flight from Fresno to Las Vegas was such a disaster! They switched planes so the majority of the people did not have a seat because the plane did not have any B seats. It would have been nice if ANYONE had made that announcement before we boarded to avoid confusion. Also, the fees are ridiculous! Your app is not user friendly at all! Who the hell charges for a carry on bag?! Are you kidding me?! The directions on the app made it sound like the $17 charge was for an additional carry on item, not the allowed one carry on item. So, when we went to check in and I was told I would have to pay $50 for my mother's carry on, it was livid! Also, are you serious with the $5 fee to print a boarding pass? I will NEVER fly with Allegiant Air again. That is absolutely unacceptable. I will say that the staff was pleasant but the airline is inept and inefficient. The reason I will never fly this airline again because of what a rip off the fees are. Allegiant Air, you should be ashamed of yourself."

Cons: "Left/ arived 30" late"

Pros: "Boarding at the new Austin South terminal was a breeze!"
Cons: "It's ridiculous to make passengers keep their personal items on the floor when most of the overhead lockers are empty. Ridiculous and dangerous."

Pros: "Great flight. On time. Easy on. Easy off. And amazing fares."
Cons: "Everything great"

Pros: "Snacks were good but we had to pay for them."

Cons: "Both original and 2nd plane had malfunctions which caused extensive delays and doubled boarding time"

Cons: "Old plane with fixed seats with very limited leg room which were not comfortable- broken window shades, scratched windows, & rattles everywhere made for a long flight. Crew was ok, I would fly again if the price was enough of a savings"

Pros: "I had 44 min they wouldn't give me my boarding pass then the flight was delayed to 5:30 and they still wouldn't allow me up."

Pros: "Being on time and the crew"
Cons: "The chair is not reclining"

Pros: "other airline seats are concave, forcing my back in to a painful posture. I'm 5'2", 120 lbs, so I'm not the normal body; but I just can't imagine who finds concave comfortable. Thank you Allegiant for a chair with a more-flat back."
Cons: "I was surprised with the carryon fee and wondered if I would have to pay fees to use the toilet. I didn't use it, so I don't know."

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."

Pros: "While I enjoy the fact that Allegiant offers direct flights to Laredo at an affordable price, the planes really need to be updated."
Cons: "We really disliked that we boarded the plane and just before taking off they made us get off again and never did confirm the real reason. The planes really need better maintenance since this is the second time in two weeks we have to change planes due to problems."

Cons: "I flew to my "surprised" 50th bday party with family and to meet more family. The aircraft problems overheated engine, caused us to get out of the plane, move all luggages and wait foe a new plane that also had to be cooled off before reboarding. We were tired and hungry. Missed my bday with family. Very very disappointed."

Pros: "The idea of a more competitive airfare. New South terminal in Austin is nice. Parking is cheaper. Food truck and outdoor seating are nice."
Cons: "No wifi. No entertainment options. You have to pay for snacks and regular drinks- even water."

Pros: "Overall good experience"
Cons: "Nothing"

Pros: "Fast flight. Good climate control"
Cons: "Flight attendants could smile or be a little more friendly. Overall good though. Could add wifi to flights."

Pros: "Low cost, great service, arrived 20 min early"
Cons: "Seats were kinda tight but I'm sort of used to that"

Pros: "We eventually got to Las Vegas."
Cons: "Everything. Spend an it make and book with someone else."

Pros: "Flight attendants were very kind."

Pros: "The flight attendants were very nice and helpful."

Cons: "Delayed the flight for 7 and a half hours. They then tried to not refund my money"

Pros: "Onboard service"

Pros: "I got to where I was going."
Cons: "Leg room"

Pros: "The extreme help of the boarding agent trying to ensure that, even though we we're leaving Great Falls late, I was able to get to my connecting flight"
Cons: "It seemed that the flight from Denver to Great Falls and the return flight to Denver was very late both times. Once due to mechanical issues and not sure of the reason from Great Falls back to Denver"

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

Cons: "Delayed 5 time and change plane 3 times"

Pros: "The fact that everything went as planned with no delays."
Cons: "Nothing"

Pros: "On time..nice staff"

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: "I didn't like every fight being cancelled, every gate being moved, and my luggage being lost."

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"
