Airline reviews

Pros: "Friendly staff. Clean, comfortable seats. Huge, very well designed overhead carry-on compartments."
Cons: "Huge delays at every airport, for every portion of the trip. Terrible communication about connecting flights, missed connections, etc."

Pros: "It was a short flight"

Cons: "Bigger leg room for tall peole 6 feet up..."

Pros: "Staff great"
Cons: "Same old movies"

Cons: "Dirty cabin, dirty glass, worn out carpet, seats falling apart, filthy privacy crew drapes. The CEO needs to be more hands on and do random inspections."

Pros: "Check in was easy. I love the way you can order from the screen infront of your seat food and drinks. In addition; you can select movies. Everyone was very nice and professional. I usually fly with jetBlue, but today I was so impressed I am considering changing."

Cons: "If there was a less than one star that is what they deserve. SFO flight was late. They gave away my seat on my connection to Kalispell. They basically blamed me for being late and not being there on time. Two others from my flight were allowed to make the connection but told me that they gave my seat away because I was late. We all showed up at the same time from the late flight. I talked to 3 people including customer service and did not get a single “I’m Sorry”. Do they not communicate with each other when a flight is late and they have passengers for connections running late? They told me they don’t talk. The best they can do is put me standby for 9:30 flight and if I cannot get on that flight I have to wait until morning. My daughter is in a competition tomorrow morning and thanks to Alaska Airlines I’m going to miss it. I’m sitting here writing this review, paying for a dinner I should not be paying for and probably searching out a hotel room until morning when I can catch a flight. Unbelievable the lack of empathy."

Pros: "Free prosecco"
Cons: "Took an hour to leave"

Pros: "Arriving at destination"
Cons: "The flight was delayed 90 minutes and there was very little communication regarding why. It would have been less frustrating if we knew the reason for the delay."

Pros: "I love that it was still a Virgin plane - please keep them as long as you can!"
Cons: "Happy with everything!"

Pros: "There is nothing about this flight that my girlfriend and I liked. This was the worst experience with an airline either of us have ever experienced."
Cons: "We didn't like that we were delayed so long that we missed our connecting flight. We were delayed upwards of 3.5 hours and watched a flight going to the same place that was supposed depart 1 hour after us, and it left 30 minutes before us."

Pros: "Nothing to complain about. It was comfortable."

Cons: "Alaska/virign’s boarding process is pretty dumb. all these different levels of people, which for a regional airline is usually 75% of the load, then, the rest. Good luck on overhead space. Literally everything else about this airline is 100% awesome. Boarding is the only lame thing."

Cons: "I checked in to the flight 24 hours ahead to ensure I got an aisle seat, because I knew I’d probably be going back and forth from the bathroom because I had been feeling ill. When I got to the ticket check to board the flight, my name wasn’t found in the system, and I was turned away to go back to the front desk. So I did, and the person there was seemingly able to get me an aisle seat in the same row, just across from where I originally was. But, when I got to the row, another man was in that spot and showed me his ticket which was the same seat I’d seemingly been re-assigned! The middle seat was empty, and so I sat there for the time being, while we enquired about it. One of the flight attendants said they’d look into it, but just seemed to brush it off and never gave us a response. I was mainly annoyed about being shuffled around, getting reassigned a spot and was clear about wanting an aisle seat, and it never happened even though I chose that seat 24 hours ahead in the first place. I felt there were a few chances to make it right, but it never happened."

Pros: "The staff is wonderfully patient."
Cons: "Gate changes, delays, presence of plane but lack of crew, food vouchers 15 minutes before venue closed. Uncomfortable seats."

Pros: "Very professional and nice crew."
Cons: "Same as above"

Pros: "Missed my flight at it was rescheduled for $25 without asking a questions"
Cons: "nothing"

Pros: "Everything"
Cons: "Nothing"

Cons: "Better vegan snacks available for purchase would be great."

Pros: "Same as before."

Cons: "We had to take a bus to our airplane. It took off a full hour late and it seemed mostly due to horrendously slow gate operations"

Cons: "They cancelled my original flight"

Cons: "lost luggage.......two days...............................19 miles away."

Pros: "1. Boarding appeared streamlined. 2. Plugs ins for tech. 3. Coffee smelled amazing. 5. Seat size seemed larger than most airplanes."
Cons: "1. Wifi or gogo did not connect. 2. It was a tad bit cold."

Pros: "The staff was friendly, a nice experience"
Cons: "We arrived early and had to wait on the plane for 5 to 10 minutes and it got hotter and hotter. I wonder if there's anyway they could have told the ground crew that we would be early so that we did not have to wait"

Pros: "the ease of booking"

Pros: "Excellent service. I would fly this airline again!"

Pros: "Would be better to allow blue Tooth headsets to view tv/movies did not have wired head phones and did not want to purchase them."

Pros: "Over an hour late leaving San Francisco, over an hour late leaving Seattle! One delay after another. Spent more time in airports than on planes"
Cons: "Delays!"

Pros: "There's not much to say.The flight was short, only a couple of hours, and I slept thru the small goodies' handouts. Anh their WIfi is free."

Pros: "The cabin was miserably hot"

Pros: "My flight was delayed by two hours, but I got to go on the earlier flight (that left at my original time), and they even gave me a Premium seat!"

Pros: "Nothing. I didn't take flight due to punishing re book procedure that Alaska employs to basically steal money from it's customers."
Cons: "They weight the value of 1st leg much higher than the return AND they want to charge you $125 change fee. My grandma passed away and I needed to reschedule my itinerary. Alaska stuck to their policies (you know, those pages of microscopic text that is written by lawyers for sole reason of screwing the customer.) I just felt really abused; told them to keep the useless "credit". I booked with Delta. At what point does a company forget who they are supposed to be serving? Perhaps the people that are actually giving you money and keeping you in business?"

Pros: "First Class was so comfortable. The attendants were efficient and attentive, and the breakfast meal was delicious."
Cons: "I wish there was a dinner meal, but the cookies were delicious too!"

Cons: "needed more water"

Pros: "Everything"
Cons: "Everything"

Pros: "I appreciate the steward giving me something to eat for breakfast."

Pros: "Play more Christmas carol during Christmas season"

Cons: "I'm still waiting to board FIVE hours delayed."

Cons: "they lost my partner's luggage by our last stop"

Pros: "Gina at Seattle Customer Service managed to get my on a flight back to my original Oregon location when it became evident that they couldn't get me to San Francisco as booked and I missed my appointments there."
Cons: "I never made it to San Francisco. After starting in Eugene they sent me to Seattle instead of Portland where I was way-laid for 5 and 1/2 hours Alaska posted a crew based delay on my flight to PDX and booked me on a flight an hour later to Seattle where I was going to have a 3 hour layover. The connecting flight was then delayed another 2 and 1/2 hours. I missed both my appointments in San Francisco and never made it to SFO. Also, they never sent me an SMS or email alert to the changes. The agent also had me wait at the wrong gate in Eugene. And they couldn't get me on any other flights to my original destination. I will reschedule my appointments in San Francisco and I will definitely be taking American Airlines or United Airlines."

Pros: "everything"
Cons: "no complains"

Pros: "This flight was fine. It wasn't really anything to write home about - nobody went above and beyond; nothing was terrible. It could have been better, though. The flight actually landed a bit early, which was nice since it was a bit of a late flight."
Cons: "Pretzels. The in-flight snack was pretzels, which is innocuous and also super boring. Also, no entertainment to speak of."

Pros: "Comfortable seats, polite & cheerful service, on-time flight!"

Cons: "* Long line for check in * Flight 137 from Denver to Seattle was almost two hours late * seats on airplane don't recline and there is not an adjustable headrest to hold my head in place * The flight attendant wouldn't let me put my paid-for carry-on luggage in the overhead bin above our seats (we were sitting in row 2, seats A,B, C). She said they were reserved for row 1. So I had to place our paid-for carry-on baggage in the overhead bins above row 4. * no movie or even reading material at my seat * No complimentary snack or beverage (only available for purchase). Are you kidding me? I paid extra money for carryons and check-in baggage for all three of us, and my experience on Frontier made me feel like a second class citizen.
