Airline reviews

I was very surprised that at the Seattle airport, Alaska's main hub, that the gates were very small and very close together, and it was very hard to discourage between my flight, and the flight next to us going to Boise and the flight next to that going to Denver. Denver. The audio for all three Gates was at the same level, and almost impossible to differentiate unless they actually said their flight number and location. Location. People tried to get on our plane, before they were ready, because they were confused about the Denver announcements. We were on a Boeing 737- 800 00, that must have recently been redone. It actually had USB--c ports which really surprised me. The Apu was out on the plane, so when we got on it was very very hot. A lot of people were complaining. The gate agents were very professional, but it was a lot going on and even though there were two of them, I think they could have used another person to help them. Mandy was particularly helpful in getting me a window seat. Flight crew was up to the usual Alaska airline standard, which is very high. Can we please get another snack then garlic pretzels? It would also be nice, if they knew ahead that the flight was full, to offer to let us check in our bags for free at baggage check, and not at the gate!

On time, good seats, not overly full, up beast positive crew.

Airport security lines in Seattle were awful. The only staff that was pleasant and made the trip more enjoyable was the young woman at the gate in Seattle. She was so pleasant and helpful. Flight attendant on the plane seemed like she would rather be anywhere but on that plane.

People were friendly. Flight was a little delayed. Maybe I missed the reason for it. Overall a nice experience.

Crews were friendly enough. To help the airline I checked my carry on baggage. Typical "gonna be a full flight we need 19 carry on bags to be checked to help out". So I helped out only to have to wait 30+ mins for my luggage and risked not getting to my car rental on time. The return flight was delayed. Kept hearing employees say something about "they didn't have any power" which is kind of concerning. The air flow and air conditioning was insufficient. It was warm and stuffy during the flight. Plus no free wi-fi......Booooooo!

Didn’t even get on, check my flight to Seattle for details. Do better Alaska.

A five hour nonstop flight traveling over a few time zones and over the dinner hour and you get a small bag of pretzels. And no screens to watch movies. I

The flight kept getting delayed due to a maintenance issue. That happens, but there is no excuse for changing the gate FIVE TIMES, including one time nearly all the way across SeaTac. After we were delayed for 3+ hours, they did send us (via email) a $12 meal voucher...except you can't find a $12 meal anywhere in that airport, unless you consider a bag of M&M's and a bottle of water a meal. The plane had one problem after another but finally took off 4.5 hours late. This caused us to miss our hotel shuttle at ORD (they didn't run past midnight and it was 3 am) so we had to wait 25 minutes and pay for an Uber. I did get a $50 flight voucher from Alaska...big deal. Barely covers my Uber ride that I shouldn't have needed.

I upgraded to a better seat and it was much more comfortable. Nobody serves food anymore and actually on a 2+ hr flight not necessary. I didn’t even get water.

Check in & bag drop was straightforward. Alaskair changed the gate approx 40 min before departure, and I only became aware due to Google wallet update to my boarding pass. Had to move from gate N1 to C9 which required use of the Train, luckily I had time available.

The crew was attentive and personable. The plane was clean and the seats comfortable. It was an excellent trip!

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

They cancelled our connecting flight resulting in another layover reaching our final destination 8 hours later than scheduled.

Repurchased food and it was moldy and expensive. But I figured it was bad luck so I purchased a cup-o-noodles, halfway through them we hit turbulence and the flight attendant was passing with the garbage, it would have been two seconds to grab it, but he was snarky grabbed someone else’s plastic cups and went to buckle up… I used the puke bags to secure the soup before it became an accessory. When he finally came around he gave me a face like a petulant child as I handed him the soup neatly wrapped in the paper then plastic bag. I watched a movie in silence as the rental or headphones was ridiculous at 4€ for those .10€ cheap plastic toys. No English subtitles on an American movie… crazy. I disliked the whinny little tourist trap and now I hope that it sinks into the ocean or erupts in a catastrophic eruption for their beloved “I live on an active volcano” pride.

The Check-in process at CDG was confusing and the crew was not helpful. But the flight was on-time and that is most important to me.

On-time arrivals and departures. Crew helpful and friendly. Yet everything costs extra: seat selection, food, even airphones!

Pleasant, attentive flight attendants, but they’ve got to upgrade their seats to be a true “business class” carrier.

Was a bit surprised that Icelandair flies a domestically configured 757s on long-haul flights to Iceland (no lie-flat seats in business class).

When you consider the price I ended up paying for everything. This was not a good deal! I had no idea that this airline had changed to a bargain basement no frills airline. So, it was disappointing to have to pay for every little thing. The only thing included was water and coffee. You have to pay for everything else! So I just felt nickel and dime.

The movie choices were poor. The worst problem is the treatment of passengers durinng pre-boarding. In one case the primes were checked in and sent down the boarding tunnek only to stand waiting there while the plane is cleaned. In the second case the bus was loaded, the doors closed and just stood there unmoving like sardeines in a tin for over TEN minutes. In both cases it was rough on us old guys who find standing for long periods trying.. In other words, Donnt just stack us up and forget us.
