Airline reviews
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: "Very late .missed connection. Agents in Detroit were worthless to get us on different connection"
Pros: "Movies, baggage price, snacks, friendly! And check carry on when full fir free"
Pros: "That we finally arrived."
Cons: "That we didn't arrive even remotely close to when we were supposed to."
Pros: "crew was nice and pilot was informative."
Cons: "1. flight was delayed twice, which meant my arrive was delayed in Cincinnati. 2. boarding was a nightmare. After 2 delays, I was crammed into zone 4. I dont fly as often, the seats space seems to be getting smaller. 5. I sat next an overweight person. I didn't like my personal space violated. 6. The flight offer movies, I slept. Yet kept getting elbowed by this overweight neighbor. 7. I am a single, independent person. I prefer to sit near the front. First on and settled and 1st off and gone!"
Cons: "Having an option for someone with wheat allergies ... As well as peanuts .... Chips work as long as they are not friends fried in peanut oil. I found that the crew would hit into my shoulder without saying "excuse me" ... Other people passed by me and they didn't seem to have a passing without banging into me."
Pros: "Overall the experience was okay."
Cons: "Flight attendant was the most intense covid person I’ve experienced on any flight... militantly going up and down the isles making sure everyone’s mask was perfect. Annoying to say the least."
Pros: "Very quick flight, arrived way before the estimated time of arrival."
Pros: "The crew did great"
Cons: "During covid-19 they are not even attempting at providing a modicum of social distancing. Every seat in both of my flights was completely filled, meaning that we were squished up next to everyone despite any efforts to stay 6ft away from each other in the airports. Many passengers were wearing their masks incorrectly (not covering their nose, TAKING OFF THE MASK TO SNEEZE) and were not being asked to wear their mask properly by staff. I felt completely unsafe and won't be flying American again until there is a vaccine for covid."
Cons: "Don’t get the egg salad breakfast sandwich. It’s got more turkey and cheese than egg salad."
Cons: "Seat pitch was too tight, especially when the person in front of me pushed their seat back."
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."
Pros: "Quick and easy"
Cons: "Overbooked flight. Had to check in carry on for not having any space available"
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: "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: "Quick flight , no complaints"
Cons: "The leg room for the seats is so tiny compared to other planes I’ve been on"
Pros: "Fast and effective. On time and crew was nice and helpful."
Cons: "They passed out drinks late !! Too close to landing time ."
Pros: "What wasn't there to like it was truly amazing. I had a great time."
Pros: "The crew and flight was excellent. Two short flights to get to my destination."
Cons: "Their new fare for budget flights processing is outrageous. I was advised booking the flight carrying size only undervfront seat storage. Then got an email explaining how this works. Then tried to checkin online 24 hours prior and you can't since you are not checking baggage. Got to airport to find that can't checkin except at counter as you need a UAL employee to scan their I'd during process to get boarding pass. Waited for employee and then she was rude about it. Again reminded me I can't bring anything else onboard or will cost me extra at gate. If UAL wants to offer this they need to be more customer friendly. I was far from impressed for the inconvenience I experienced being s longtime UAL Frequent Flier."
Cons: "Seat area had a good deal of trash around it and in the seat back pocket"
Pros: "We arrived safely on time."
Cons: "Bathroom is too small. Announcements were anxiety inducing. Sick people on the airplane spreading germs."
Pros: "How nice the crew was"
Cons: "That I was in the middle and lost my phone at the airport"
Cons: "Flight was changed on me last minute so I had to call United and see if I could negotiate a better flight time. Layover in LA went 3-4 hours longer than expected so I ended up getting in a lot later than expected, meaning I had less time to spend with my wife. I missed my flight on my way back - I think when everyone was boarding, I somehow misinterpreted the digital sign that said "Ontario" to mean that they were boarding for Ontario. I had to sleep in the airport that night because I missed the flight - most uncomfortable experience ever! I paid for United's lounge but they weren't open 24/7. Then they almost didn't let me in the next morning to the lounge because technically it was only for that 1 night, even though I had been at the airport all the same. Lesson learned - maybe I should just drive to SD rather than fly."
Pros: "Quick trip."
Cons: "Other passengers. People are really do well on flights these days."
Cons: "Frontier is an airlines that doesn't care about its customer. Period!"
Pros: "They did a great job and baggage is free for active-duty military"
Cons: "They did a great job and baggage is free for active-duty military. Bathrooms were clean and staff was professional."
Pros: "Cost of ticket"
Cons: "Paying for bag delays and the chairs and no free snacks offered"
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: "Cheap flight . Luckily looked into there baggage rules. Cheap flight means they don't offer any entertainment nor complimentary drinks.I didn't know this but would use thier services again and again at the prices I paid."
Cons: "The change of flights. Had to stay in airport overnight!"
Cons: "Over an hour late. Again. Never flying frontier in the future. This was my first and last experience with them."
Cons: "the seats.. the space.. the arm rests.. the tray tables.. everything"
Cons: "The delayed flight and the smell of puke for the entire duration of the flight after an indicidual puked before leaving the gate."
