Pros: "Pilot information/anoucements."

Pros: "Same as above"
Cons: "Same as above"

Pros: "Everything best airlines I've ever flown."

Pros: "The air gods and goddesses who looked after us"
Cons: "Nothing"

Pros: "Very smooth landing"

Pros: "It was fast and friendly. They took a lot of guesswork out and made us feel safe."
Cons: "The planes were a bit small for flying 6+ hours. I started getting restless at having to sit in the same position for that long."

Pros: "On the ground ..TSA said I needed a new boarding pass..3 kiosck wouldn't. Work. Friendly re sent me to Alaska desk where they printed me a new boarding pass but when I went to TSA. I had no passport. Sooooo..back to t he Alaska desk and a wonderful rep named Diane helped me hunt through all my "stuff"...then began talking to all reps helping process passengers. She never gave up. And found my passport at the desk that had made me a new boarding pass. I was so upset I couldn't think straight but she did!, many thanks to this kind lady."

Pros: "When landing in Burbank, we were able to exit the plane from both the front and the back! Since I was sitting almost all the way in the back of the plane, this made it very easy for me to exit the plane quickly. The plane also wasn't full to capacity, so I was able to have an entire row to myself!"
Cons: "Our landing into Burbank was very rough! We came in very fast and it was quite a scary experience."

Pros: "Alaska Airlines is by far one of the friendliest airlines!"

Cons: "No closed captions --"

Cons: "I checked a bag and an small animal kennel that was empty. When I got to my destination, the kennel did not arrive. They could not locate it, but said they would have it delivered to my home the next day and they would give me some coupons. When it did not arrive the next day, I called and they said they could not find it. I explained that I had flown back to move the rest of my belongings and my cat and not having the kennel was now causing me to buy another. The agent said they would reimburse me for buying the new kennel, but I would have to call and get the number and submit the receipt. I understand they need proof, but I never received the coupons and don't feel I should have to jump through hoops due to their error. They should have reimbursed me for the $25 I paid to check the kennel and paid for a new one. Why would they think I would want coupons for an airline that could not keep track of one piece of luggage?"

Cons: "Multilpe delays"

Pros: "This was our first time flying Delta and it was a very pleasurable experience. Boarding was very straight forward and the seats allocated comfortable. A surprise for us was being asked if we would like to move seats from the back of the aircraft to Comfort Economy (we think it was to do with weight balance! but appreciated very much none the less). The flight attendants were very professional and helpful, as you would hope all attendants on all airlines would be. We'd gladly fly Delta again anytime."

Cons: "We are letting too many people with the flu, travel. This in turn is spreading it to other places and getting too many people sick. We need to control this more. I don’t have an option after spending all this money on if I can stay healthy or not, and that is not ok."

Pros: "arrived alive"
Cons: "If you're remotely claustrophobic this is not the flight or aircraft you want to be in. When the flight was booked and paid for I was under the impression that I would have a seat on the plane. As it turned out in order to board the plane I had to pay extra to secure a seat. If this is not a "bait and switch" operation I don't know what would qualify."

Pros: "AA has been good to me--- Gold card a big help."
Cons: "The LAX concourse could at least 2 more coffee shops in addition to Starbucks.The wait was 40 minutes at Starbucks to get a cup of coffee!!! Get on the ball LAX!! We need our caffine in the morning."

Cons: "My friend and I have taken our hiking packs to Alaska, California, Washington, and all along the East coast. Never have we been asked to check our packs. I was mostly surprised, at first. Once I was seated a man in front of me had his hiking pack and two ukuleles in their cases, neither of which could fit under his seat. That's when I became frustrated. O This plane sucks: our knees were slammed into the seat in front of us because the chairs are so close together. No USB plugs. Plane was dirty, scuff marks on the wall and ceiling. There was paper in the pouch that looked like a mouse had chewed on it."

Cons: "Nothing"

Pros: "And it was actually terrific. United employees were top shelf at every stop, on every plane. (I did seven flights total.)"

Cons: "Shitty service ,...."

Pros: "It was great!"

Cons: "Cacelled then delayed twice. United workers are also very rude. I give them a big ol"

Pros: "Rhe food"
Cons: "Custmer Service"

Pros: "On time."
Cons: "New looking plane but the TVs behind all the chairs were locked without a credit card. The new chairs looked great until you sat in them. I'm 5'10" and my knees were already brushing up against the seatback in front of me. If you push the recline button on the armrest, the chair doesn't go back (of course it doesn't, the person's legs behind me are probably up against my chair anyway). Multiple people around me were also asking around if the chairs recline. I have a mild back injury and sitting up at 90 degrees the entire way was very uncomfortable."

Pros: "Changed my seat to a better one"
Cons: "Plane an hour late taking off"

Pros: "More important than the trip home last Wednesday was the reason for the trip. We attended my granddaughter's wedding. Everything else was secondary. Even if the trip had been in a one wheeled barrow, it would have been good. To get to what you want which is the mechanics of the trip. The two people who attended to the aisle chair, most teams were competent. Some hadn't done many passengers so they were fumbling with the straps. I've learned that I almost alway have to ask for one at the gate where they check or issue, (what's it called, loading permits, some kind of pass, not landing pass. loading pass. I can't remember and my wife has gone to bed.) Well, they have to come up with an aisle chair because I've only got 1 1/2 legs. I always make it to the seat on the plane, but the competency of the various crews is uneen. Sorry my answer is so nonspecific but I don't remember one airline from another. Great people all, get the job done."
Cons: "Not much I don't like. They get us there That is the main thing. Sometimes when the plane stops after it has pulled away from the Jet Way, the pilot gives an explanation that I find unfulfilling, not enough details. I suppose if they explained more, other fliers would find the explanation too verbose. I can live with it. Again this is about all flights and airlines. Nothing stands out, such as, " this awful thing happened when we left San Francisco.""

Pros: "Getting off the plane"
Cons: "Everything was cramped- not enough space to move. They completely ran out of overhead space. Completely crazy"

Cons: "Snack offering was caramely sugar cookie"

Pros: "I learned to stop flying Air Canada or United affiliated partners"
Cons: "Just about everything else"

Pros: "Attendants were amazing"

Pros: "Both flights were early, which was nice for a change."

Cons: "No TV"

Pros: "BEFORE BOARDING, THE STAFF WAS SUPER FRIENDLY AND ACCOMMODATING"

Pros: "Everything not TSA related."
Cons: "The racist OKC TSA. The line was moving along and the TSA agent sitting behind the podium checking boarding passes put his hand up and asked me to wait there. There weren't that many people in the lines, so I was wondering why. His partner at the other podium watched him quizzically, as did I, as he paced left and right, looking at nothing then sat back down again and stared at nothing. All the while the line for screening grew smaller and smaller. The other agent asked him, "what are you doing?" He responded by saying, "You said you were getting THEM all." I didn't understand, but clearly there was some subtext that I was not privy to. She shook her head and said, come up here sweetie. Then she managed to do what he obviously couldn't do: his job. Then my girlfriend and I proceeded to be profiled and had our bags searched. If I didn't have to be in OKC I would avoid that airport like the plague. Unprofessional."
