Airline reviews

I was in the middle seat in the last row but that wasn’t their fault. It is why I rated the flight as mediocre, also the landing was a little rough. The good was really good. The self service luggage belt at SEATAC stopped working right when I reached it. I was literally placing my bag on the small belt when the main belt stopped. I understand that it wasn’t just Alaska but the entire side of the terminal. It took the agents about 20 minutes to arrive at a game plan and it certainly wasn’t flawless but they arranged for our luggage to be taken to the plane the old fashioned way by hand. Understandably, the plane was late in leaving. The flight took the proper amount of time and instead of arriving at OAK at 1:45, we got there at 2:30. I took my time getting to baggage claim because I knew it would be late if it was there at all. Sure enough it wasn’t but there was an agent there to greet me and inform me about my luggage. Long story longer, they delivered my luggage to where I was staying which was an hour away from the airport. Alaska has instituted a delivery type tracking system through my email that kept me informed of where my luggage was the whole time. WELL DONE!!

Crew was very friendly. Our bags showed up at the carousel within 20 minutes of arrival.

Flight was delayed and hour due to tire issue. First flight of the day, this issue should have been discovered prior to boarding.

Both legs of the trip were delayed about an hour. Planes were new, liked the WiFi availability and entertainment available. Crew was very good. People were happy and helpful. Liked the pilots - they provided updates throughout the flights. Snacks were underwhelming. Drinks were good! Like the smaller sodas and they actually came through the cabin 2x which was great. In Seattle airport the construction caused much confusion for Alaska. Process of printing own tags, etc was chaotic for people who didn’t check in online prior to arrival which in turn caused issues for those who did. Plus airport gates were too small for the number of people flying.

We did have to wait an hour for the runway to be cleared but other than that it was fine.

My seat row didn’t have tray tables which made it pretty difficult to get comfortable on a four hour flight. Good experience outside of that, though.

There was no sitting place in Sea-Tac airport. Even airline didn’t provide any food or dinner. I will never take this airline in my future travel.

Crew was very rude and uncaring. When someone tried to place their bag in overhead bin and they asked for help, crew told them they could not assist. Crew member then told the customer if they couldn’t place into overhead bin on their own, they should have checked in bag. When other customer helped to place the bag in the overhead bin, they were given evil look by crew member and told to hurry back to their uncomfortable middle seat. This was despite the fact that the plane did not leave until 30 minutes later. The flight was ~80% full; when final people boarded, they were forced into middle seats with no room for comfort. There were a handful of emergency row seats unoccupied. When asked if any of the emergency row seats may be used, the crew said that they would cost extra. Normally if a flight is completely boarded and there are open seats, the crew at least gives thought to asking someone if they want to re-locate to the more comfortable seat, especially on a long flight.

I am always uncomfortable about the boarding process. I think every airlines has their own procedures for boarding but all of their procedures are inconvenient because it takes too much time to board. If you board people from back seat to front, I think you can reduce the time to boarding.

Our original fluffy was cancelled. Our substitute flight didn't fly. We lost out on our hotel and car rental. Had to fly out the next morning. Alaska didn't give us any meaningful information. The first flight was scheduled to leave at 4pm and the substitute flight at 9pm. We left the airport at midnight for a hotel. No weather. Beyond disappointed.

Delayed and took off even later than the scheduled delay time

Food was surprisingly good but the WiFi was not great

Easy boarding with an extremely kind attendant. Seats were spacious and we had 3 seats for 2 people so we could stretch out. Comfortable air flow and very attentive and hospital attendants. Bathrooms and food were the only negative. Bathrooms were so small you could hardly get in and close the door. I don’t think an obese person would fit or a person with a movement disability. Food was the trending food for flights, nonexistent. We spent $40 getting sandwich and snack at airport for our 6 hour flught.

There was a security issue at the airport and we were unable to land. We circled endlessly and then landed at another airfield for fuel. We then circled the airport again, almost landed but didn’t fully touch down before circling again. I am thankful to the crew for keeping us safe- the issue was the airline and staff at the airport getting us seats on our connecting flights. That part was hours of searching for someone and getting in double my steps.

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

Flight was delayed long enough that I was misding my connecting flight. The agents could not get me on a comparable flight, nor could they get me s Main Cabin seat I had paid for, nor could they get me on a comparable connecting flight. The gate agent would not issue meal vouchers, even though I was delayed over six hours! I had to spend over an hour and 15 minutes with customer service on the phone to See if they could get me on a better flight and get a meal voucher. Customer service was not helpful enough in trying to find alternate flights and it Ended up taking me 24 hours for a 12 hour trip!! Delta does not provide upgrades NOR will they even give you a pass for a few hours to their lounge. They claim that they do not issue daily passes to their lounge anymore. I call BS since this would be no extra cost to them to provide excellent customer service and give you a few hours to relax in comfort when you’re sitting in a crowded airport and your flight has been screwed up for that many hours.

Food from the flight from Atlanta to Santiago was very poor..

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

The flight was supposed to leave at 7:30pm, but departed 10:50pm. They kept moving departure time out every half hour. It was a 45 minute flight from n Sunday night with great weather.

The crew was great! It was nice to have a pillow and blanket... It gets cold on those flights. I paid extra money to sit where I thought was extra comfort seating, but it wasn't,... So, I was mad a bit about that. I'm hoping our flight home will be better.

Flight got delayed and it was very inconvenient . Had to come with another carrier. Had to spend one more night in San Francisco.

Logging into next flight was an issue as I never received a confirmation code

Alaska airlines is not what I expected Very disappointed Unfriendly Discouraging Very bad customer service, heartbroken trying to explain to them my situation.

I could not check in ahead of time. Kayak did not give me a proper confirmation number to check in.

I loved flying Hawaiian Air! We didn’t pay to sit together, but we were able to anyway. They had usb charging ports and even outlets in some seats. They served a hot sandwich that was not very good, but we were still pleasantly surprised. The staff was very nice. The seats really made my booty hurt but maybe I’m just not used to sitting so long. Also, the AC was really cold even though I was wearing pants, a hoodie, and a light blanket.

The crew was great, the food is decent for airline food, and we flew economy but the seats are comfortable and had plenty of room for my 15 year old son and myself. Would fly Hawaiian Airlines again for a long haul flight in a heartbeat.

A second drink service on a 6 hour flight would have been helpful.

The steward staff was particularly friendly and helpful. They smiled a lot and seemed anxious to be sure we enjoyed the flight.
