Alaska Airlines misleads customers. Our flight was booked as a direct flight, and they added a stop without informing anyone. Do not fly Alaskan Airlines.

Alaska Airlines misleads customers. Our flight was booked as a direct flight, and they added a stop without informing anyone. Do not fly Alaskan Airlines.

The flight was canceled so i booked another flight with Delta, so essentially there was absolutely nothing that i enjoyed about my experience with this flight

You guys are always have delays and then leaving us on the tarmac for 15-20 min. FIGURE IT OUT!

Flight cancelled. Bad service at customer service line. Missed dr appointment

Probably the worst 1st Class I have ever experienced. Sam, our flight attendant, was excellent. Other than that, everything from the Alaska Longe experience to the buggy app to the uncomfortable flight and uncommunicative agents were poor. The agent who booked us in forgot to mark TSA PreCheck on our boarding passes and we had to go back to get this done. They were a cut below every other airline we have experienced in just about every area.

my first time with Alaska Airlines, an exceptional airline with great employees.

The plane was late arriving at the airport which in turn we left late. I had to literally run to my next gate to catch my connecting flight and my luggage did not show up at my final destination.

Seattle flight to Walla Walla has a confusing doorway system . Small signs once you leave gate area to tarmac. Almost went the wrong way to my plane.

Please don't shrink the seat space any more, as United has done. Thanks for all your good work.

The flight was delayed almost an hour causing many passengers to be at jeopardy of missing their connecting flights. There was no help in providing passengers help with connections or allowing passengers with connecting flights to exit the plane in an expediated manner.

Everything was ok!! Just bags came up a little be late.

Tasty snacks. On-time departure and early arrival. Luggage arrived quickly at the carrousel. The only negative was a man behind us that was heavily inebriated. He was served 3 double drinks during the flight. There was no telling how much he had before the flight. He was so out of it that he spilled a drink and broke the heavy liquor glass on the floor. I don't believe he should have been served so much alcohol on a two-hour flight.

Kind staff. Snacks are small but that’s the new normal.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

Flight left early and arrived early. the whole trip was excellent.

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

Very dissatisfied with the fact that I had upgraded to first class for the second part of my trip only to find out that the lounge was still not available to me, as well as not having any food or drink service on the flight due to weather, so I lost out more than what I paid for.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

The seats are uncomfortable, feels like a small seat pad on plywood.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence.

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

Not as good as expected Air Can needs to improve totally rated on internet as worst

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Everything was good. Flight was on time, luggage pickup was quick. The staff were great. Could not ask for anything more.

lots of delays the crew were unclear about where to pick up my carry-on, which they took from me to check in on the plane.

They needed people to check a bag, they did check my bag and I had to wait 10 minutes after the flight to get it it wasn’t too bad

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

It was 4 hours late. Almost missed my connecting flight no food or drinks on connecting flight. Overall terrible experience

Lost my luggage. Filed a report and there is no response. Received a phone call from another airline that said they had the bag and they did not know what to do with it

Very good over all , would have been nice to have entertainment on the flight

Absolutely the worst airline I have ever taken. They lost my baggage and told me my bag tags had been cancelled. When my bags arrived days later I had to pick them up at 3:15 am. My return flight was delayed another 6 hours and they broke my bag. Westjet does nothing to try and make it a better customer experience and all the customers services representatives I spoke with were useless and incompetent. Never flying westjet again.

Easy self checkin and baggage drop. No in seat entertainment, but wifi and app worked well

it's all good nothing you can do make better 😌

Single flights to Cancun purchased through third-party, initially had issues printing luggage labels with the lady at the airport Pearson… Was super friendly and assisted quickly despite being very busy

Very old planes. Seats were not comfortable. Air was not on during the flight leading to incredibly stuffy conditions.

The flight was on time and shorter time arrival than planned. I was an ultra basic passenger and understood one personal item on the plane. The announcements of one personal item and zone 9 boarding certainly felt like we were separated from the rest. Actually zone 9 passengers should be boarded second; we are not blocking aisles and can be seated much faster and deboarded faster too.

Still sitting in a hotel when I'm due for work

Delays happen but communication and care were very low on what ended up being a long day.

I like the free beer and wine but not the delays to the departure time.

Never again flying economy on Rouge!!! Literally like sardines!!! Will try to change to better seats 3 seat arrangement only so so if traveling with family. Who wants to squished to stranger!!😖 Can’t say enough bad about this!!!

I booked and paid extra for exit door seats also pre paid for my luggage air Canada changed plains and I never got what I paid for and they made me pay for luggage again they also did this to my wife. They are the most unorganized company I have ever dealt with. I am sure I will never see the extra money I paid for the seats or the recharge for the luggage. They are subsidized by the taxpayers and don’t give a dam just a horrible way to do business

Overall the experience was excellent. Plane was clean but more importantly quiet. Recently, I’ve noticed that Airbus planes seem quieter than their Boeing counterparts. I definitely prefer flying in an Airbus plane.

Delay after delay.......they are awful Delayed because of cold wx really!!!!! We live in Canada

My one complaint was that while we boarded using the standard enclosed gangway, when we arrived at SEATAC, the ground crew were slow to hook up the stairs. After reaching the tarmac we had to walk up a long ramp all outside in 35° weather. We just came from Bali and did not have warm weather clothes. This was in addition to having to collect our bags in Vancouver, take them through security again and then having to show our passports 4 more times all within the Air Canada section.

So we didn't actually go. We were hoping to go for the Inauguration of the first female president. When That Guy got elected, we bailed. Unfortunately, we got basically none of our money back, despite having travel insurance. Would not fly with Air Canada again unless I had to.

flight was delayed, there was open communication about the delay the delay pushed way past the posted delay time and

This was my first time flying on Air Canada and the experience was good and pleasant enough, great crew members and the price I paid was amazing,
