Cons: "Nothing. Terrible customer service; horrible experience."
Cons: "Flight delayed by 40 mins, then left 40 mins after scheduled even including the delay, no free in seat entertainment and the wifi was broken. Really not a fun flight overall. Also, please Alaska, get rid of that Cabernet Sauvignon that's sweeter than grape soda. Single worst wine I've ever tasted."
Pros: "The crew was great. Friendly and helpful"
Cons: "A 5 hour Departure delay."
Pros: "It was on time"
Cons: "The first class crew were TERRIBLE! They were obviously not happy to be there or be working. Didn’t check back on us, didn’t pick up our empty glasses, and didn’t even say goodbye. Too busy just talking to each other. I assume this was because it was an American flight. I’ll fly Southwest next tim"
Pros: "Great crew, nice service, comfortable."
Cons: "Nothing. Loved it."
Pros: "Seats were pretty roomy in coach."
Cons: "NA"

Cons: "A little more food on the 4+ hour flight. Otherwise a great experience!!"
Pros: "Yes"
Cons: "Everything was great WiFi didn’t work but I don’t care, just letting you know"
Cons: "Flight attendant was on phone rather than greeting customers as we deplaned."
Pros: "I always enjoy Alaska but this was another level. I was horribly late and still processing at security with 10mins until take off and the guy at the gate called me to see where I was - gave me mins to make it - which I did - just.. I was traveling to San Diego to meet my family for the weekend - I would’ve been in severe trouble had I missed the flight. Thanks Alaska!!"

Cons: "Nothing"
Pros: "The attendants were great"

Cons: "Horrible the worst first class ever seats were outdated and uncomfortable the amenities (snacks) where just bad they had better snacks in coach . The customer service is even bad as well worst mistake of my life"
Cons: "There was only water served then 30 minutes before landing they served juice. We had to ask if we wanted some of the cookies they are suppose to give out"
Cons: "For the first 1.5 hours of the flight one of the flight attendants was talking bad nonstop about previous customers. Then when we landed there was a passive attitude in her tone when she told everyone to exit the plane quickly because they had a flight leaving right after and needed to clean the aircraft in a timely manner. Overall a poor experience traveling to San Diego Alaska flight 1164 September 12 6:00am departure."
Pros: "I had no problems with my pet"
Cons: "Great flight fast Only thing was I didn’t get my boarding pass for my second flight and I had to go through security all over again"

Pros: "Nice roomier plane lots of leg room in main cabin"
Pros: "The flight itself including technicalities, take-off, landing and functionality went really well and I felt safe. the staff were very friendly!"
Cons: "My chair did not recline and I was not made aware of that when I chose that seat. Also did not appreciate how hot the window beside me got luckily the fan helped with that. Wifi sucked, did not work on my phone at all and it seemed everyone around was able to stream shows but I was stuck in a n uncomfortable seat unable to sleep because of my upright position and unable to enjoy any entertainment as wifi did not work at all and there were no TVs or other options for me."
Pros: "The mood lighting on the plane."
Cons: "Not applicable; everything about this flight was great!"
Pros: "The crew was excellent and the aircraft was clean."
Cons: "The only downside was the plane had no food and the announcement wasn’t made until we were already boarding (they didn’t know either - not their fault). I was expecting lunch since I was in first class, but the crew did as well as they could to provide us with snacks."
Pros: "Boarding was fast"
Cons: "I paid to upgrade to a larger seat and it wasn’t much better . The flight had no WiFi and pretty much no entertainment on the iPad they had us pay for either . I will stick with Hawaiian Airlines ."
Pros: "Usb and 120v plugs in seats. Got a row to myself."
Pros: "Every Alaska Airlines employee went above and beyond to make sure our family had a great travel experience. Our seats were assigned together, we were not charged for checking smaller bags, and the beverage/snack service was fast and they checked back often. Seats on this plane were roomy and the flight was not over-crowded. Boarding and de-boarding were easy and relaxed. Arrived ahead of schedule."
Cons: "Wasn't offered any water or snack, only stuff for purchase."
Pros: "What’s not to like about this airline? Honestly, I am such a fan of their Airlines that it’s hard to imagine flying any other in the United States."

Pros: "Flight attendant sang a corny song"
Cons: "Nothing"
Pros: "Boarding and expected part of the flight were fine."

Pros: "Every employee was professional, the plane on time, the landing was smooth."
Cons: "I can't say anything nagative for this flight."
Pros: "everything"
Cons: "Assigned seats separated from my husband. I'm seated in the middle of a couple, while my husband is on the other side of the row. Not happy at all"
Pros: "The first-class flight attendants would sometimes help the main cabin passengers and were generally in a better attitude and much more helpful."
Cons: "The plane was changed and my "Premium" seat was downgraded. The seats were uncomfortable and much too cramped. I paid $89 extra for premium seating, and when cancelled upon, was only offered a $25 credit for future travel plans. Since I cannot count on Alaska, I'm not sure how soon my "future," travel plans will be ..."
Cons: "There were no blankets and it was a bit cold on the flight"
Pros: "My return flight was precisely on time, boarding was efficient and the offer for a free chat service while in the air (though I didn't use it) was a nice touch."
Cons: "While my flight was short and snacks weren't necessary, I was pretty underwhelmed by the snack offerings."
Pros: "It was fine. We thought we had one free bag but we're told we didn't. Really typical of flying today. Everything cost extra, bags, food etc Pretty typical"
Cons: "The free movies they offered would never load even when I downloaded the material needed."
Pros: "Great Upbeat Crew makes for a pleasant flight!"
Cons: "Nothing"
Pros: "I returned on Flight 552 from PDX to SAN. I really want to appreciate the patience and good humour of one of the crew, Becky, who was serving us. I will certainly fly Alaska again."
Pros: "After an absolutely horrible experience with United, we ended up switching and booking a last minute flight on Alaska. So glad we did, they got us there on time, the plane was comfortable, snacks were good and the tablets for movie/TV watching were great. Most importantly it was a direct flight instead of 3!!!"
Pros: "Promptness of departure"
Cons: "Very crowded"
Pros: "Love the leg room and the seat comfort. Loved free WiFi for free movie options. Staff seemed more interested in talking to each other, which is fine unless a guest needed something extra. They weren't bad, just not exceptional."
Cons: "Extra luggage fees, extra food fees, snacks soooo unhealthy."
Pros: "It was my first time flying with Alaska. I was pleasantly surprised with the boarding times, organization, super-friendly crew, free entertainment (a few select movies with complimentary tablets to view them on), and outlets for charging mobile devices in every seat. Easily the best flight I've had in a couple years. I will fly with Aaska again."
Cons: "I felt like the aisle was unusually small ( I was sitting in an aisle seat and was occasionally bumped by people walking by me. Then again, I was in a deep sleep most of the time and could have easily been leaning into the aisle....I'm not really sure. Overall though, best flight I've had in a while. They really do a great job."

Pros: "Despite boarding late, and sitting on the tarmac for half an hour since we missed our take off time, and having to move passengers around to balance the weight on the plane, we made it home alive."
Cons: "We landed over half an hour late. Flight attendants needed to move passengers to balance the weight on the small plane, and asked for "volunteers." When there were none, the FA stood in the aisle and said we just weren't going to take off if nobody volunteered. They should have just MOVED people."
Cons: "Ran 2 1/2 hours late, poor customer communication"
Pros: "Charging at every seat is great."
Cons: "All of the plane extras (e.g. WiFi, food service, etc.) were out of commission for some reason. Without WiFi, I couldn’t watch anything on my own device, and I would’ve had to pay for a headset that is compatible with your screens."

Cons: "It was so late I missed my connection to sun valley flight. There was not another flight for 8 hrs!!! I think the sun valley flight should have waited for us. It was a matter of 10-15 min.

Cons: "There was an infant in the seat directly behind me that chose to cry and scream through a large part of the flight. The mother of this child did not/was not able to keep the child from crying.

Cons: "Should offer free water at least."
Pros: "the crew was very helpful"
Cons: "seats could have been a little wider"
Pros: "Crew, check in and access"

Pros: "The price was excellent."

Pros: "No leg room & very misbehaved children sitting behind me. The children screamed the whole time, kicked our seats, and the mother had no control. If you are any taller than 5’9”, you may want to consider an exit row seat to have room for your legs. My knees were jammed in to the seat in front of me."
Cons: "They could have not been 8hrs late"
Cons: "There was no way for us to add another bag after our seat placement. No one answered the phone for Alligent and the website didn’t work. It costs $20 extra to do this at the airport. Even though it was not our fault that there was no one answering phone calls (and no way to leave a message)"

Cons: "Nothing. I did not try food or entertainment on this flight."
Pros: "The staff were friendly and helpful and boarded us in an orderly manner."
Cons: "Staff are part time employees and do not arrive to check in counter until 1.5 hours before flight. When flying out of this airport you do not need to arrive 2 hours early."
Cons: "The seats were a bit cramped but I suppose most are these days"
Pros: "The plane was very clean and well lit. The crew was excellent. Very friendly and nice."
Cons: "The seats are pretty uncomfortable. They are so close together and there is no room to store anything. The tray tables are a joke, you can't even fit an iPad on them. The bag check process was trouble at both legs. They have lower weight limits than the major carriers and that really should be highlighted better when you book with Allegiant. Also, bag checkin for the flight I was on started at 7:45am. There were only 2 people at the checkin counter and one of them was busy doing something and ignoring the customers. So that was a little annoying."
Pros: "Check in was fine Wait was short Crew was great!"
Cons: "Seats REALLY UNCOMFORTABLE SAD Could not have updated the seats on newer Jets."
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."
Pros: "nothing"
Cons: "flight delayed 3 times didn’t leave until 11pm 3 hours late last delay because pilot was late. didn’t get home until 3am."
Cons: "5 delays between for a 4:27PM flight that eventually took off at 3:15am. My biggest issue is the unrealistic delay that could have left us in the airport for 11+ hours. Very thankful that they did allow me to change departure locations to another airport at no charge. That flight went well, even arrived early."
Pros: "People in my row."
Pros: "Quick non stop."
Cons: "The ground crew got something stuck in the snow and we can't get off the plane because of that."
Pros: "Excellent value. They had hard time with the head count which delayed our take off. Arrived just a few minutes Late."
Cons: "Sent email out asking for volunteers to reschedule her flight. Got on the plane our seats were not the same as selected. And we paid more to select our seats. Friend of ours seat was switched also and instead of him sitting next to his wife he sat next to a person who did not have an assigned seat he was extremely large and he was hanging off The seat into the aisle I noticed an empty seat and had to ask the stewardess if he could switch seats instead of the stewardess offering on her own. The flight out was delayed approximately one hour various mechanics coming on and off plane until finally we were able to leave."
Pros: "Mostly the Price! Wonderful Crew Too!"
Cons: "Wish they had flights on Friday and later on Sunday..."
Cons: "Flight cancelled on the way to the airport due to weather. Weather wasn't due to turn bad for 36 hours."
Pros: "Snacks were good but we had to pay for them."
Pros: "Flight left and arrived on time. Boarding was OK."
Cons: "Not even water provided on flight. I miss amenities."
Pros: "Very efficient service... actually a good experience."
Cons: "The airline nickel and dimes for everything."
Pros: "Being on time and the crew"
Cons: "The chair is not reclining"
Pros: "Efficient check in, no hidden fees (all were explained via email well before the flight), fast boarding, take off and unloading. Time left and arrived on time. The staff was extremely friendly."
Cons: "The seats were bare bones and not very comfortable but I guess that's what helps keep costs down."
Pros: "I never have any issues. Everything is always great."
Pros: "Quick boarding with priority access Friendly staff"
Cons: "Unclear boarding instructions. Both flights roundtrip were delayed about an hour. Wasn't advised of seat changes and reasons why. Mobile passes were unavailable due to a system issue gate attendants had to check manually. Bring own snacks or eat before flight and provide your own entertainment. Seats not reclining are uncomfortable. Not suitable for someone with back issues. First flight was uncomfortably cold return flight was uncomfortably hot."
Pros: "Everything they could control went very well."
Cons: "The flight had a lot of turbulence, but that's not their fault. I thought the pullout handled the situation well."
Pros: "Nothing. We were scheduled to fly back to Vegas at 7:07 then delayed to 8:30 then 10 pm then 11:25 pm now 1:15 am. This is unbelievable, unacceptable and ridiculous! And I have to work the next day. This is unacceptable! I just received another update that now we're leaving at 1:45 am . Please do not, again do not use Allegheny EVER again!!"
Cons: "So many delays. This airline is unreliable, unprofessional! Ridiculous! Please read my comments above. Do not use Allegiant!"
Cons: "Nothing"
Pros: "didn't like anything"
Cons: "delays"
Pros: "The prices are good. Anything additional (food, overhead carry on space) is an additional cost but this is how they make the tickets cheaper for people who don't need extras."
Cons: "Leg space tight. Seat didn't recline. They said the maximum width on the under seat personal item is 7 inches but space is big enough for wider than that. I felt that was misleading."
Pros: "Very clean, great staff, smooth flight, easy boarding. All the things you could expect for a great experience. First time flying with this airline so I didn't know what to expect but it was great!"
Cons: "everything was poor"
Pros: "I am a little disabled... Am in a electric wheelchair, can't speak very well, this was my first flight alone and my chair would not lock in upright position after unfolding it. (If I leaned back on the backrest it would collapse/fold up. I learned I had to lean forward to keep it up.) Everyone was very accommodating and very helpful! At the Provo Airport they gave me a regular wheelchair and I showed them how to remove the lithium battery, remove and stow the joystick and how to fold my chair. No drinks or snacks unless you pay for them. On arrival I waited for everyone else to exit but also took advantage of the lavatory to relieve my bladder ;-). They were waiting trying to unfold my chair. I gave them instructions to step there and lift on the arms and up it went! I showed them where the joystick was, they pulled it out and connected it to the arm, put the battery in the bag, plugged it in, zipped up the bag and I pressed the green button and Voila! it was done! Thank you to the Awesome Allegiant Crew!"
Pros: "The crew was good and had customer service"
Cons: "After an 36 hour delay and only $8 meal voucher in Las Vegas, highly disappointed!!! The next flight was late arrival and Late boarding. everything to include water and sodas are extra fees. not impressed and will never fly Allegiant again"

Pros: "Flight was fine"
Cons: "Please don't board us and then proceed to make us wait on the plane for an additional two hours. The flight is onnly 80 minutes... and we waited in our seats with no entertainment or services for two hours. Please do not board passengers when you know that we won't be able to take off -- that's ridiculous!"
Pros: "These people have no idea who or what United Airlines is. They work for Delta, and make sure they tell everyone about it."
Cons: "See above. The flight itself was fantastic. Larger planes are the best! Thank you!"
Cons: "A very rude boarding agent insulted a young man from another country who was boarding in front of me. He misunderstood that they wanted him to check his luggage instead of carry it on. The agent yelled at him and shamed him in front of other passengers. United strikes again!! Seriously folks, you suck!"
Cons: "No leg room"
Cons: "Zero entertainment. Too cramped"
Pros: "Lovely crew. Nice seats. Smooth flight."
Pros: "The app promoted me to check in on my phone and would not allow me to check in. So I assumed the time on the ticket would be my boarding time. I was late for my flight."
Pros: "Comfortable seats"
Cons: "My 10:00 p.m. flight was canceled so I had to spend the night trying to sleep in the airport. Have you ever had to do that? Not fun."
Cons: "The day after my flight I received an emailed receipt of the the customer in front of me of her lunch order, I’m sure it was an honest mistake but to me paying attention to details like that is very important. There was no personal information on the receipt, I was just wondering on how it was emailed to me instead of her."
Pros: "The staff were fine, nothing really great, but nothing bad either."
Cons: "So, we'll start with boarding. Why airlines can't figure out to board the plane from back to front is beyond me. No, let's load front to back so everyone has to uncomfortably shove past the people who have already taken their seats at the front of the plane. Then you get back there and all the overhead bins are full because everyone takes as many bags as possible onto the plane. Then you have to sacrifice the already tiny amount of foot room, "to put the bag fully underneath the seat in front of you." At this point you should be fine, except if you're over five and a half feet tall (I don't know if that's true I'm 6'2" and 275 lbs,) because then your knees are going to be buried so deep in the chair in front of you that the person up there doesn't even need a seat they can just sit on your knees. Luckily for you tall people, they put a nice metal rod just about knee level to really dig in and cause pain . . . Yay! Being a big guy, you try to be considerate and fold your arms in to give the person next to you as much space as possible, but don't expect that back as they'll spread out and become as wide as possible. Then to distract yourself from the discomfort, you try to use the free in flight entertainment via the United app, but "it's not available right now." In summation either be short and small or be rich and buy the seats with extra legroom when you fly United."
Pros: "I liked the customer service wfrom the woman who helped us find a way with patience to get a working card to get our luggage checked in. I liked the customer service on the flight they were attentive and friendly."
Cons: "The options to pay baggage with one card is rough on the average traveler, the baggage charges cost as much tickets!"
Pros: "Fast flight"
Cons: "N/A"
Cons: "slightly delayed"
Pros: "Everything ran as expected"
Cons: "Nothing"
Pros: "It was hot...the whole flight"
Cons: "Hot hot hot"
Pros: "No much"
Cons: "Suggestion, why don't the airlines charge to use the bathroom, so the money humgry grubs could make more money"
Cons: "I saw my bag come out of the baggage claim ripped open. My stuff coming out. My zipper was complety destroyed and my locking mechanism on my bag was ripped off even though it wasn't locked."
Pros: "Great flight attendants"
Cons: "Seats too small"
Pros: "Lack of services for price"
Cons: "Lack of services for price"
Pros: "The plane was newer at least. And I made a big enough stink when they made me check my bubble-wrapped framed paintings that they actually did get hand carried and made it okay."
Cons: "These are the smallest seats I have ever experienced on a domestic airline. I'm 6'-4" and I couldn't fit comfortably on their newer 737. The thing that took the cake was that the cabin crew absolutely refused to let me take one of the 5 empty exit row seats telling me that it wasn't fair to the people who paid more, which absolutely enraged me. So then apparently it's also fair that their seats will fit someone who is 5'-4" comfortably but not someone who is 6'-4"?? So it's fair that I can't afford to pay an extra $100+ for it after my profession got gutted in the recession and I make a fraction now of that I used to make? Making your customers suffer for no good reason is inexcusable. I will not be flying United again. Ever."
Pros: "Crew was friendly, flight was on time."
Pros: "Arrived safely and almost on time despite late departure."
Cons: "Boarded plane in nonsensical manner. Had to try to walk opposite the flow of traffic to find room in overhead luggage compartment. Plane was too cold."
Pros: "quick and easy flight"
Cons: "overhead wasn't full but they still tried to make me gate check my bag"
Pros: "The call center that i was forwarded to that did nothing to help at all or the agent who hung up on me while i was trying to get an explanation of why they keft me stranded in the airport."
Cons: "Kayak.com"
Cons: "Never made it!!"
Pros: "The crew that bothered to show up were fine, not overly friendly as they SHOULD have been due to the extreme delay."
Cons: "I checked in online and printed my ticket a few hours before my flight, so I was dropped off at the terminal where my gate was supposed to be. THEN after I get through security, I find out my gate has been changed to another terminal- one for international flights. I had to walk for 30 minutes with my heavy carry-on to find the correct gate. Then the flight was so incredibly delayed because a flight attendant decided to just not show up for work. So unprofessional! If the flight had been delayed because of uncontrollable conditions, then that would be another story, but come on! A flight attendant not showing up for work? That's pathetic."
Pros: "Food"
Cons: "Plane didn't have entertainment"
Pros: "All"
Pros: "The crew was friendly"
Cons: "Some passenger were allowed to carry more them the 2 bag carry on rules."
Cons: "The flight was a little pricey, but that was to be expected from my short notice purchase!"
Pros: "They were prompt and polite"
Pros: "Flight attendant was extraordinarily kind, especially for the couple sitting next to me with their adorable 7-week old baby."
Pros: "Didn't fly to San Diego-got rerouted to LAX instead. Had I continued to San Diego I would have landed almost 6 hours later than my previous arrival time all because of delays at the gate in Harriaburg. An original 30 minute delay from weather is understandable, and by the time the aircraft arrives you'd think they'd be ready to deplane and get it rolling quickly. Nope, not all. I think it was amateur day in Harriaburg because it was like no one knew what to do and nobody could make their minds up."
Cons: "See above. This is why I drive everywhere."
Cons: "Delayed flight so they transferred us to American which turned out to be delayed and we missed our connection in LA and had to stay the night. They could not find us on the computer system because of the transfer. We took the train home at our own expense. Not happy with costumer service. There was a lack of efficiency and care. We were in the air for 4.5 hours but spent two whole days traveling. No thank you united and American!"
Pros: "Everything else was fine."
Cons: "Once we boarded the flight people started getting text messages that there was mechanical issues and there would be a half hour delay. Crew didn't even know. Then pilot said there would be an hour delay because they had to wait for a "deadhead" pilot. That should be unacceptable."
Pros: "Same as above"
Cons: "I have flown with United on many occasions, several of which were international flights however I was never more uncomfortable on a flight than I was in economy on my flight from ORD to SAN."
Cons: "After sleeping in the airport all night, I was put in the seat next to the restroom which smelled really bad"
Pros: "The girls at boarding area watched Tucker while I had to go back to the security area to get bracelets that I had forgotten they treated him like a king"
Pros: "The in-flight streaming of movies actually worked pretty well -- just be sure to install United app on tablet if you want to use that instead of phone."
Cons: "An extra 1 inch between seats would make the difference in allowing passengers to open a small laptop and position it so they can simultaneously type and see the screen at a viewable angle."
Cons: "Since plane was delayed I missed my connecting flight so I had to stay the night in the San Fran airport for over 7 hours. For another 1 hour flight. With no accommodations or even a food voucher was just told to find a nice corner."
