Pros: "The crew was amazing and they were all really polite and helpful!"
Cons: "My headphone jack was broken so I couldn't listen to all the great movies they were offering. It's a little thing that changes the whole experience."
Pros: "At 7 PM July 21 we booked flight through KAYAK linked to Alaska airlines. That part worked and picked seats. We were unable to check in online (try again message. At kiosk 525 am San Diego airport it would not allow us either. By the time we made it to the desk it was 537 am. They would not issue."
Cons: "Ironically we had no issues checking in for the return flight through Delta Sunday 7 pm when we booked the flights. Therefore we could not leave San Diego and Alaskan Airlines front desk said we were three minutes late in person and would not issue boarding passes. We missed our soccer playoffs."
Cons: "Flight delays. Departure gate change and long walk across airport"
Pros: "It was from missing my connecting flight since I wasn’t able to get to my destination that day I had to wait a day."
Cons: "Pay for my parking since I had to leave that day and come back the next day."
Cons: "The airflow is too far from the isle seat making it a bit uncomfortable for the middle seat. The lack of entertainment outside of using a personal device was meh. And the price for some of the features are aggressive. Unless you are a T mobile customer..."
Pros: "The red head steward"
Cons: "The hipster sitting next to me and the small seats"
Pros: "Nice flight attendants"
Cons: "45 minute delay pilot said it was because a lot of planes fly into Seattle. The plane was obviously late coming into San diego. 3 day old tuna can smell in airplane. No food. I hate this airlines."
Pros: "Flight was fine and on time."
Cons: "They make such a big deal out of the cheese tray—I think they’d be better stocked. They ran out by the middle of the plane. The flight attendant let me know I should reserve one next time. Now I know."
Cons: "Bag did not arrive at arrival gate and was late"
Cons: "Flight was late and crew was very rude about it. Not to mention the flight times kept incorrectly updating and I almost missed my flight even though I was 4 hours early to the gate. Worst experience flying that I have had."
Pros: "When I asked for a seat change the crew was very accommodating"
Cons: "With covid in Seattle I was placed next to a restroom. I did not see any bathroom sanitation occurring during the flight, and no sanitizer available anywhere."
Pros: "Flight was good and crew were good. Nothing very outstanding but by no means a terrible flight."
Cons: "The in flight screens weren't working well."
Cons: "Bring ear buds if you want to watch/listen to a movie. Delta changes for ear buds Everything else was fine"
Pros: "Good flight as always with Delta. Sat in economy comfort, so of course the seats was comfortable. Flight Attendants were great."
Pros: "Check in person was very helpful in rerouting our flight."
Cons: "Our flight was delayed 3-1/2 hours. The gate crew booked us in another flight but did not issue a ticket, so after transferring to another terminal, we were sent back to the Delta terminal to be issued a ticket to a third airline since we already missed the second flight. Then, they lost our luggage"
Cons: "Seats did NOT recline, which seems to be a pretty poor planning for a red eye flight."
Cons: "The boarding process at LAX was awful. I’m sure the horrible shuttle wait and transfer from terminal to terminal is the airport’s fault, but the airline did not do anywhere near enough to inform passengers of what was in store. It was confusing and annoying."
Cons: "They did great. The weather was poor, so it felt more like a roller coaster ride home. Made it safe and sound. Would’ve been nice to get an update is speaker about change in weather and the rough ride in store when the whole ride was so turbulent."
Cons: "I checked two bags and paid for them. The flight was full. I dutifully got in line for zone two. Next thing you know, at least 25 people got to board early and have free bag check. Really? I should get $35 dollar refund."
Pros: "That we finally arrived."
Cons: "That we didn't arrive even remotely close to when we were supposed to."
Cons: "Don’t get the egg salad breakfast sandwich. It’s got more turkey and cheese than egg salad."
Pros: "My first time flying Alaska Airlines. Absolutely will be back. Comfortable, spacious seating. Staff was professional and friendly. Flight was seamless from beginning to end!"
Cons: "Excellent flight, no issues"
Pros: "The plane was uneventful. The AA crew and employees at DFW were rude, unhelpful, uncaring, and showed extreme disrespect to my disabled Veteran husband."
Cons: "The AA crew and employees at DFW were rude, unhelpful, uncaring, and showed extreme disrespect to my disabled Veteran husband. We will NEVER visit DFW again. We were treated with disrespect and rudeness. My new name for this airline is UNAMERICAN AIRLINES."
Cons: "The flight comfort was very bad. The plane was extremely warm and people we beginning to feel bad. Several mentioned it and asked multiple times to have the the cabin air conditioning turned down"
Pros: "Nothing. I missed this flight because of a delay of my flight on Friday."
Pros: "Free tv which is rare"
Cons: "I had selected my seats ahead of time and they weren’t kept. Day of I tried to buy a seat and it told me there were tech issues and I had to go to a front desk to check in/purchase. Well all that got me was the very last row, middle seat. No recline and seriously no leg room or breathing room once the person in the row ahead leans back. Crew was not helpful. Not to mention, the security line was outrageously long and I got to my flight just before it left only to find out my seating arrangement and be presented with more disappointment. Took over an hour where I’ve never waited more than 20 minutes in this airport (I fly often). Didn’t have time to go to BR or grab a snack Then my second flight was (again another middle seat) way too warm. The attendants said “there’s nothing we can do”. I was so nauseous and uncomfortable the whole time."
Cons: "The original booked flight was about 12 hours before the rebooked flight. We got up at about 2:00 am to leave for the airport at 3:30 am for a 6:30 am flight. We were all packed and booked our ride and shuttinlpg down the computer at the last minute when we noticed an mail after midnight telling us the flight was cancelled. We called and were told there was nothing they could do, due to connections and this was entirely their fault. Approximately 12 hours later we took a “red eye” thus arriving a day late for our hotel and car reservations. We were charged baggage fees and not sure if our priority boarding will be refunded."
Pros: "Comfortable chairs"
Cons: "Pilot's skill level and ability - lots of maneuvering and a very poor landing"
Pros: "Smooth flight, pilots were friendly. It was a nice flight"
Cons: "No entertainment and no gate printed on my ticket. My flight to Dallas was delayed and I had to waste time figuring out what gate to take a train to."
Pros: "Boarding was smooth and took an average amount of time. We arrived exactly on time. Staff were all friendly and helpful. Plane was clean.. overall very pleasant !"
Pros: "The flight was very good and no problems were encountered."
Cons: "Nothing to complain about."
Pros: "On time, flight attends are superb"
Cons: "Cramped seats due to greedy corporation trying to appease the share holders"
Pros: "Nothing."
Cons: "They delayed our flight 4 times, over 4 hours, told us the flight moved to a gate that didn’t exist, gave us erroneous information about alternate flights, assigned 3 different planes that needed maintenance, and then we waited over 2 hours to talk with a supervisor. I finally had them rebook me on Alaska Airlines (the best)."
Pros: "Rapid boarding and comfortable seat. The flight attendant was great!"
Cons: "Snack selection wasn't impressive, as was the onboard entertainment unit - small screen and no flight info/map. Also no lounge access in San Diego since our ticket was through Air Canada."
Cons: "In Osaka I was not able to get a boarding pass for this last leg. In SF United and Air China were both not able to give me a boarding pass because I was not listed in their system. I have no idea why. Very frustrating."
Pros: "Fast and effective. On time and crew was nice and helpful."
Cons: "They passed out drinks late !! Too close to landing time ."
Pros: "Very smooth fligh and very friendly and helpful staff"
Cons: "The seats were extremely crammed and there were no movies or shows without purchase"
Cons: "My flight was canceled because of the hurricane in Houston which was completely understandable. Trying to rebook a flight was one of the worst experiences I've had on the phone. Over 2 hours on hold only for United to tell me to call back inside 24 hours of my requested departure (which was about 12 hours outside of the time I called). Bad customer service all around, both Kayak and United."
Cons: "Crew was rude and seemed to be in a constant rush big lack of customer service"
Pros: "Definitely can't beat the price, especially for a non-stop flight halfway across the country. I had plenty of room in my seat even with my backpack under the seat. The drink and snack selections are pretty decent."
Cons: "Delayed to start and it took a while for all the bags to be loaded. Once we arrived it took over an hour from the time we touched down to when our bags arrived at the baggage claim. Ended up finally leaving the airport an hour and a half after the time I was originally supposed to arrive."
Pros: "I arrived."
Cons: "It was an hour after boarding before take off. Another 15 minutes on the ground after landing waiting for a gate at midnight on a weekday. I understand that circumstances occur beyond the airlines control, but this has been routinely occurring on my trips with Frontier. Absent compelling reasons, I will not be flying with them again."
Pros: "Cost of ticket"
Cons: "Paying for bag delays and the chairs and no free snacks offered"
Pros: "They still pick up trash!!"
Cons: "New airbus has even LESS room!! Have to manhandle your personal bag out of the even smaller space under the seat! A soda is $3! There is Nothing to read anymore and the crew are overwhelmed with cranky people... making them cranky."
Pros: "Everyone was very nice and funny. Definitely going to use Frontier even if they cost more. The pilot gave us a smooth comfortable ride. The staff all around were absolutely professionals and kind to boot."
Cons: "The fact you wont accept gift debit cards or money. I kept my credit cards home for safety reasons. I could not buy anything. The isle was hard to walk down It was very small."
Pros: "It didn't crash"
Cons: "The whole staff from the check in to the attendants was rude rude rude. Never again!"
Cons: "The delayed flight and the smell of puke for the entire duration of the flight after an indicidual puked before leaving the gate."
Pros: "All in all the flight was typical for a low fare flight, comfortable for an unreclining chair, and as clean as would be expected."
Cons: "The only problem was that it was an overnight flight and about two in the morning members of the flight crew gathered at the back galley and began to talk and laugh rather loudly. Not only did they wake me up but they woke a little girl who began to cry loudly for some time. Perhaps they did not realize their loudness because they were friendly on and off the plane, but it was rather frustrating."
Cons: "The flight coming in before we left got there luggage lost and caused us to miss our flight because there was only one person dealing with all check ins and lost luggage"
Cons: "The carry on price and a kid crying the 2 hr flight"
