Airline reviews
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."

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."
Cons: "A little more food on the 4+ hour flight. Otherwise a great experience!!"
Pros: "The crew staff was nice"
Cons: "First off they were late then when it's time to board they change the gate on us and we had to go across the airport to get to the next gate. Then flight was fine when we landed the flight was smooth. Then we had to wait for another 30 minutes to actually get off the airplane. Not happy at all."
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: "We were to leave the airport at 3pm, but didn't leave until 5pm. So we ended up arriving at 6:30 instead of 4:30. Not happy at all"
Cons: "I was in 1st class and they ran out of breakfast options."
Pros: "Everything went smoothly and everyone was extremely nice and helpful."
Cons: "Nothing"
Pros: "The attendants were great"
Cons: "The line of people in the aisle waiting for the bathroom."
Pros: "Friendly cabin staff and one of the most enjoyable addresses by a captain I've ever heard (and seen - he was out in the first class area when he welcomed us)."
Cons: "Nothing"
Pros: "The crew at Missoula airport was amazing, and most friendly"
Cons: "Don’t be delayed by more than 1 hour. Twice the same day / both directions."
Pros: "The crew on this flight was amazing, and boarding was right on time."
Cons: "It was pretty hot on the airplane. Could have regulated the temperature a bit better."
Cons: "Great flight. We were delayed but the crew kept us well informed and tried to make up time in the air"
Pros: "On time departure and smooth landing"
Cons: "More leg room. Stop nickel and dining passengers to appease investors. Delta is an evil corporation"
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: "There was a lot of turbulence and people screaming in fear, it always makes me feel better when the crew says something reassuring to make people less anxious."
Pros: "Crew were very good"
Cons: "Seat assignments should be assigned when we checked in. They weren't for the second leg. But, the seats are fine."
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."
Pros: "SeAts"
Cons: "No entertainment no WiFi. Lots of angry people about that."
Pros: "We got there."
Cons: "We found the chart listing gate where we should go. We went there. Told the last listed flight was late so stayed there. With no announcement the gate board listed a different flight. We asked and was told gate was changed. What a surprise, Went to the info board and had to RUN to our new gate. Barely made it on time. This is awful communication."
Pros: "Love the entertainment system, watched a movie and was able to charge my phone too"
Cons: "Gate the boarding process but that's about it"
Pros: "Flight crew was great and made the flight that more memoriable ."
Pros: "Quick easy flight"
Cons: "The terminal was a long way from the main terminal and accessible only by shuttle bus. Also we had to re-check our bags following our first leg flight and subsequently couldn't change our flights to an earlier departure."
Pros: "Flight was on time"
Cons: "No individual movie screens and no way to connect to the one movie on the flip down screen since I didn't have the American Airlines app."
Cons: "The check in process at JFK was a disaster. The kiosk check in machines were constantly malfunctioning, where to line up was unclear, and staff acted frustrated. After several failed attempts with the kiosks you have to wait in line to check in at the counter anyways. It would have saved almost an hour of my time to just go straight to the counter-- had I been allowed to. I wanted to check a bag which contained some fragile items. Several bottles of wine which I wrapped in bubble wrap and cushioned with my packed clothes. I requested a "Fragile" sticker to be put on my bag. I was told "We don't do that here". So I asked if they handle ALL bags with extreme care and I was laughed at and told to go on my way. When I got my bag at my destination-- the outside of my leather suitcase was sliced to the lining. There were scuff marks and torn leather. My wine had been completely shattered. Not just a crack in the bottle, but flattened completely. My clothes were stained, my bag ruined. I don't know if putting a fragile sticker on would have prevented this, but I don't understand why they just "don't do that". We are trusting our property to the airline when we check bags. I will never trust American Airlines ever again. They don't want to know if I have anything fragile, and they don't care when I tell them."
Pros: "My daughter liked the movie Gifted on the flight. Only decent experience in 2 days of travel"
Cons: "Worst experience with an airline ever. Never going to fly AA again. They lost 3 valued customers."
Pros: "Tons of entertainment options, friendly crew, flight was on time"
Cons: "My seat was not clean"
Pros: "Staff on the plane was pleasant."
Cons: "When I checked in I wasn't given a seat assignment. I had to wait until I got to the gate."
Cons: "Old Aircraft, no power outlets, small TV displays, picture distorted, low quality LCD, mediocre Entertainment menu"
Cons: "They boarded us in spite of the fact that the flight had been delayed 40 minutes. We were all getting alerts on our phones but were told to disregard it and board anyway. We then had to sit on the runway for 40+ minutes until we could take off. Since we were traveling with two small children, it would have been preferable to spend those extra 40 minutes in the terminal rather than on the plane."
Pros: "The boarding was fast and the flight was Short. Can’t say much about the food since the flight took only about over an hour. The crews were nice and friendly."
Cons: "The flight was delayed."
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!"
Pros: "That I was lucky enough to have an entire row to myself"
Cons: "Late departure, unfriendly crew"
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."
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: "No much"
Cons: "Suggestion, why don't the airlines charge to use the bathroom, so the money humgry grubs could make more money"
Pros: "Niven cabin crew, helped without complaint when my daughter had an embarrassing accident. Very nice crew."
Cons: "No in seat free entertainment"
