The crew was great and everything went smoothly coming and going.

My window seat did not have a window. I chose seat 11A thinking I would have a view. I had a wall instead.

See what I wrote in the previous section. This was a terrible experience. I would like refund.. I even paid an extra $70 for an aisle seat closer to the front to ensure that I got off early enough to catch the next flight. The fact that the plane did not wait, and even left eearlier, knowing that the first flight came in late, and was moved to a terminal three train stops away is appalling. My friend that flew JetBlue, their flight was delayed and came in later and the connecting flight WAITED for them. How is it that JetBlue could do that, and Alaska could not.

This was my second time flying Alaska Airline in the 1st Class cabin. Everything was fine with the exception of the food and entertainment. The food was just ok but not what I was expecting from 1st Class. A BBQ pork sandwich and baked potato. There wasnt any in-flight entertainment. I found that odd since it was a coast to coast flight Seattle to Dulles. My sister flew 1st Class on Delta on a shorter flight ( Seattle to Cincinnati) and had an awesome meal and in-flight entertainment. I typically fly Delta but there wasn’t a flight with times that fit my schedule. I am by no means a primary donna. But when my upgrade cost over $900…I didn’t use any reward miles…I was expecting more than what I got. I will never fly Alaska Airline 1st Class again. I will stick with Delta for all my travel needs whether it’s in 1st Class or coach.

Good staff. Comfortable seats. Had to check my bag because the flight was too full.

Loved this first class flight! Awesome food, snacks and drinks. Comfortable seat with foot rest. Good movie. Very friendly crew! Only thing I would suggest is having a screen on seat back in front of me so I didn’t have to watch the movie on my phone.

The crew was very attentive, boarding was orderly. I really liked the way Alaska Airlines gives boarding passes and dropping off my bags. Very smooth.

Once we were in the air, the flight was nice and smooth. The flight was about twenty minutes late to begin with, though, and then we needed to wait to land for another plane to land first.

Flight crew great! No WiFi not great. Someone took my bag not great!

Alaska Airlines staff go out of their way to accommodate my fragile musical instrument, every time. They are unlike any other airline. I've experienced this can-do attitude on several flights with different staff, so this must be the culture of their company. I appreciate Alaska!

The flight didn’t happen because they apparently lost my check in and wouldn’t let me board.

I wasn’t checked in for the third leg of my flight, my bag was checked through to Dublin but when I went to the gate in Toronto they said I wasn’t on the flight and had given my seat away. I had to wait 24 hours for another flight and instead on the one I had booked it was now 2 flights.

Flight was delayed by 3/4 of an hour. Overall flight was good.

No pre boarding kiosk to check in, baggage claim detected luggage didn’t leave the airport, poorly managed recovery of lost luggage, and blame lost tag from conveyor to TSA/security, very poor from TSA/security check to delivery, crucial if compensation will go thru and will likely wait for months unlike United,

I didn't think about not having the right app for wifi because my connecting flight was with Westjet and when I took off from Seattle I was thinking I would use my wifi, but realized I couldn't on my Westjet app and I did not have Delta's app downloaded.

Plane seating was uncomfortable, very tight fitting for someone my height, did not recline and overall un enjoyable

No communication from Kayak or West Jet. Booked extra flights, flights cancelled, no one answers calls. Will be disputing charges.

Leg room is a problem the plane was dirty and there were no movies available on the app

The personal item sizer cannot take a standard backpack, and the cabin luggage sizer cannot take a standard carry-on. Designed for people from the island of Lilliput!!. and also compels people to pay additional fees to check their bags. Making money by ticking off the passengers is a very short-sighted business strategy, especially since they have a choice of carriers

Our flight was delayed almost 3.5 hours (some of the issue seemed to be weather-related, yes) but NOTHING was offered as an conciliatory gesture for this delay. No food offering or any additional drink offering. There is no entertainment is available on any screen behind the seats. The airlines are so quick to penalize customers for slightest requests for comfort- seat changes, complicated baggage allowances, seating zones which are utterly dehumanizing (ZONE 9? after Zone 4- why? This is so clearly meant to be a message to those that do not have 'loyalty' to this airline to make a distinguishing line in the sand. There is such a lack of humanity in the way people are corralled in and spoken to. So, I don't think airlines should be all that surprised when those some dehumanizing corporate treatment is returned to them when asked. The flight on the way into Calgary was scheduled to arrived at 9:25 and we arrived at 12:45 AM. It is not okay. I would think TWICE and possibly once more before booking with them again. Their overhead bins are small and limited so they bully you into either paying for a $90 checked bag or gate check a lot of people's bags. Often on their website there is no carry-on bag allowance. Beware!

All good……but luggage didn’t make it on the airplane. Had to wait 3 days. Was a bummer.

Small suitcase used for carryon the last time was refused by boarding crew this time. Appears to be at the discretion and mood of the person on the day. Flight was only half booked, there would have been no problem with space.

Our original flight was cancelled due to mechanical reasons. This cancellation caused us to miss our connection and we were not able to get another flight for 3 days and then needed to make an extra connection to get there. Air Canada did not rebook our flight for us, it took several hours of talking with staff in the airport and making phone calls to get the flights rebooked. We never received a voucher for our hotel and meals while we were waiting for our next flight and it was only after talking to several staff that we were provided some general information about how we could be reimbursed. We tried entering our ticket information in the website provided, but it did not recognize our flight information. When we asked someone on the phone about this they said we'd need to contact the customer relations department, but that it's not possible to reach them on the phone. I don't understand what company would have a customer relations department that you can't talk to. We spent about $1,000 for hotels and meals for our family while waiting for a flight home and I'm not confident we will ever get reimbursed for this. I understand that mechanical issues can happen to any airline, but this is the 4th time that this has happened to my wife and I on Air Canada and we have only flown Air Canada about 8 times, so this is not a good track record. Also, when we did finally get a flight home (which was also delayed due to mechanical problems), we were told we couldn't bring a standard carry on even though the information on our ticket clearly indicated that we could bring a carry on bag. The staff at the gate were not understanding about this situation.

It was very cold in the beginning; then I asked stewardess to do something about that, and she did something, so for the rest of the flight the temperature was closer to normal. It is typical: by some reason the pilots or whoever is in charge make the cod in the cabin unbearable. The seat is better than on WestJet or Flair, but is is very tight. No leg room.

Terrible, luggage’s with b/p and diabetes meds including insulin and ozempic. I’ve in them had dissolved and rendered useless

We were happy with the service and cost of checking a bag

Very nice staff members are very nice and friendly helpful

The internet connection was perfect, and the updated entertainment systems that allow me to connect my Bluetooth earbuds was excellent

Just the stress of possible cancellations on flights from Air Canada, but all went as planned and everything was perfect! Thank you

It was good to receive a card for my birthday
