Wifi should be free. Also, the seats were super uncomfortable. I know it's an airline, but dang.

Pros: "Alaska air has WiFi for customers and comfortable seats which is awesome"
Cons: "I heard a kid ask for sparkling cider! That would be so awesome at least during holiday traveling for the month of November thru January"
Pros: "The crew was great. I love the hot tea selection on Alaska."
Pros: "Was a nice flight all around."
Cons: "One first class passenger was served a little to much alcohol. He got pretty loud but nothing was done to quiet him down. That was the only bad thing."
Pros: "Good boarding process even when every seat was full."
Cons: "More legroom. Not asking for a ton, but at least another 2 inches. My knees were killing me by the time we landed, & it was only a 3 hr flight."
Pros: "Crew was great, the flight was good. Food is good but expensive."
Cons: "Free or inexpensive food options would be nice. I also prefer when the screens are in the back of the seat and I don't have to stream on my phone or pay high prices to use data."
Pros: "Crew was friendly"
Cons: "Tray tables very dirty, flight overbooked, hard to find gate agents"
Pros: "Nothing. Missed the connection due to being on the tarmac/runway for over a hour and a half. Missed my connection"
Cons: "Everything from flight schedule to customer service could have been better. Alaska Airlines is horrible"
Pros: "Biscoff cookies are the best please never stop serving them!"
Cons: "We were almost treated as if we were stand by people instead of paid passengers. They didn't give us seats until the last minute because we used saver prices... Because i found a bargain price i get treated as lesser? Not cool."
Pros: "My bags were about 3 pounds heavier than allowed and she let me in with them. The crew is overall very nice and professional."
Pros: "Crew was super amazing and friendly! Very good service also!"
Cons: "No seat back entertainment.."
Pros: "Boarding process need to be improved. Seat assignment is horrible"
Cons: "It was fabulous as always! Thank you. I love Delta!"
Cons: "We weren't alerted there was a chance of delays. Over two hours late."
Pros: "Great seat easy flight. The food always seem to be the same. I wish they would change it up every once in a while. I've been on this flight 14 times this year and its always exactly the same.."
Cons: "The gate was under construction in Seattle, and it was impossible to hear the gate agents."
Pros: "Crew was very friendly and efficient. Flight was pretty smooth."
Cons: "On time departure would have been nice. 2.5 hours late."
Cons: "Was not offered a drink in first class prior to take off."
Pros: "Use my built up miles for the SEA-ANC leg of our trip, as to physically price it out as one ticket usually increases the fare by 300-600 u$d depending upon time of year. As it was the tail end of an already long journey (OKA-ICN/ICN-SEA), booked the First Class Cabin. Every mile was worth it."
Cons: "N/A"
Pros: "The crew really kept us updated on the many delays."
Cons: "There were SO many delays and they kept changing. At one point we got on and off the plane."
Cons: "We paid for comfort plus but the seats were no different than main cabin. Comfort plus experience on other legs was much better."
Pros: "This airline is completely disorganized and with no apologies. I waited an hour in a bag drop line and then an hour and a half in the plane with no real explanation as to why. Planes are super bare bones which is fine. They just seem to be incredibly understaffed and unorganized as a company. All of the attendants and desk workers were trying their best but were set up for failure"

All of the attendants and desk workers were trying their best but were set up for failure"
Cons: "I didn't like having priceline involved in my purchase. I did not care to use priceline, as I didn't get to pick my seat at purchase, or pay for my checked bag. The price went up when I went back to pick my seat and pay for baggage. Therefore I will not be using kayak again."
Cons: "My seat was not worth an extra $50. Sat next to a lady with a stinky dog in her lap that was probably a little too big for lap."
Pros: "Quick boarding, and fair service"
Cons: "Nothing super fantastic to say, but also no real complaints!"
Cons: "I can't believe you have to pay $40 for carryon!!!"
Pros: "Nothing"
Cons: "Extra charges, couldn't check in online without paying $45 and worst customer service EVER!"
Cons: "First of all I had to deplane because of sewer issues that took several hours to fix. Caused issues with my rental car. Then a $45 bag fee each way on a 2 hour flight that cost $160. That's freaking ridiculous. They say it's a value to fly frontier when it is a complete rip off plus they wanted to charge for coke. Complete joke. Total dillataunts"
Cons: "The breaks failed on the plane so we had to deplane at the gate. They couldn't get us out until late the next day so I had to cancel my trip."
Pros: "Fast boarding"
Cons: "Checked bag was $40 each way and everything cost extra. No drinks etc."

Pros: "Nice crew. Smooth process overall."
Cons: "Seats were tolerable for a short flight but not for much longer."

Cons: "Communication amongst the airline and it's PAYING customers, TERRIBLE."
Pros: "Quick non-stop destination flight booked a day before for very cheap. Wonderful."
Cons: "Nothing."

Cons: "n/a"
Pros: "Great for anyone simply looking to get from point A to point B - no fuss!"
Pros: "Flight crew was nice enough, but the intercom woman was very annoying; spoke like we were children. How many times do you need to announce a last bathroom call? 1 is diffident. 5 is excessive."
Cons: "Charge you for EVERYTHING. Seats were so small i couldn’t bend down to find my headphones in my bag on the ground. I’m 5’4” 115 lbs. no in flight WiFi or entertainment. It was a long flight."
Pros: "Great trip. Just got me to LAX on time and easily"
Cons: "Everything was fine"
Cons: "I usually don't care too much about my flights from LA to Seattle since it's only a 2 hour flight. This was my first time with spirit and it was horrible from start to finish. Staff was unfriendly checking my bag in (I had to pay $82 for ONE checked bag), boarding the plane was a complete unorganized mess, the flight was bumpy and uncomfortable, the beverage I asked for on the flight was out of stock, the landing was horrific. By far, worst 2 hours on a plane I've ever experienced."
