Airline reviews

Pros: "Crew was very service oriented. Appreciate their constant offer of water."
Cons: "Someone should know how to make your entertainment system run on iPAD. I preloaded your system before boarding. However, even though I can access your menu, I can not play any movies. The crew tried to help but no one could figure out how to make it work on iPad."

Pros: "Movie options and healthy food"

Pros: "Crew and actual flight were good."

Pros: "The in flight crew work hard in providing frequent services"
Cons: "Entertainment—most movies are a few years old."

Pros: "Nothing."
Cons: "Put on an American carrier despite having booked with Alaskan. Told the wrong gate. Then told the incorrect boarding time at the correct gate. Missed flight due to gate keeper. Had to gheck my back on the next flight despite ample room to carry on. EVERYONE that works for American Airlines is incompetent, rude and terrible. I WILL NEVER FLY YOUR AIRLINE AGAIN. Your company should be sold off and every employee fired."

Pros: "Fruit platter. On time. Efficient. Professional Plane was very clean"
Cons: "Seattle airport first security man grumpy. Not helpful. No reflection on Alaska airlines however"

Pros: "The crew is consistently on point ! Accomadating , friendly and warm !"

Pros: "Everything."
Cons: "Nothing. Alaska is by far my favorite airline! Virgin is my second favorite. They are now joined. Perfect!"

Pros: "Boarding was efficient, seat was comfortable. I appreciate that food and drinks were offered often."
Cons: "One particular flight attendant purposely ignored me when I tried to ask for cream and sugar for my coffee which she did not offer when handing out drinks. Then she looked right at me twice as I tried to give her my garbage which she was collecting, but she ignored me again and left me holding my garbage until a different flight attendant came much later and took it without incident. It made me wonder if it was because I looked Asian- she was helpful and polite to the white women next to me. I was polite and was not being difficult in any way. I'm half white, but was often treated like this in Illinois when I was growing up. She should have been professional and if she had I would have rated the trip as excellent."

Pros: "Same as above."

Pros: "George Yoo"
Cons: "Nada"

Cons: "Seating felt a little more cramped than usual."

Cons: "Barely any free snacks, aside from water. Everything either needed to be paid for or was advertised in a way that eventually got annoying and overwhelming. I felt less like I was on an airplane and more at one of those promotion things where you have to sit in an uncomfortable chair for three hours listening to a guy in a suit talk about boats before you can get a free fast pass ticket to a ride at Disneyland."

They ignored me (who was first) for a white couple who Came after me, and they got chosen and got the flight credit, but I was as clearly first. So I think it was more of a racist matter"

All should of went well from there but they sent me to the wrong gate. Luckily I just made it to the correct gate for boarding. Upon arriving at Chicago there was no one available to provide information on how to get to Royal Jordanian gates. Also on my AA portion of my flight coming into The U S in New York the flight was cancelled and I was told the next flight Available was next day (18hr delay) at the other NY airport.

We were expecting no charge because the bicycles were our only check-in baggage for the trip. Couldn't believe the lack of transparency with which we got hit with this charge. Qantas, Air New Zealand, and other airlines we've taken bikes with us on our flights have charged nothing when we traveled in the same fashion. So, if you are a bicyclist traveling with your bicycle, I'd avoid the United-Lufthansa duo."

Cons: "My husband, sister, brother-in-law and myself flew into STL. We thought we had booked the same flight but when we got there found out our departure flight was different. We asked about moving them to our floght but it was over booked so we asked if we could move to there flight. They had 15 open seats. They told us no. There would be a charge of 500 dollars if we wanted to change. We decided to just fly out first and meet them there. We stood by the counter to speak about meeting. As we did we could hear them telling the next couple that they would have to move to the later flight. It was a huge problem for them as they would miss there connection. We then offered again to take the later flight so they could take our place on the over booked flight and make there connection. They where unwilling. Then we get on the flight and the plane was nasty and dirty. We put out tray table down and there was drink and dirt all over it. When asked if they could be cleaned we got an attitude. They never came back to do it. Luckily I had a wet wipe to do it. The plan smelled like urine. Same was true for our return flight. The plane was very old and not taken care of.
