The pretzels have no taste. How about a choice of snacks? The flight itself was fine.

The pretzels have no taste. How about a choice of snacks? The flight itself was fine.

This was my first time using Alaska. The best thing about Alaska is the people. Everyone that I had any contact with couldn’t have been better. So far on this trip no complaints. I will use Alaska again

Full, attentive service from the fist class cabin flight attendant was superb. Really exceeded expectations.

The stewards were too loud and chatty with each other

Definitely one of my favorite airlines! I always have a great experience with Alaska!

We sat on the tarmac for 25 minutes after landing and it caused me to miss a connecting flight. It turned a 7 hour travel day into a 14 hour travel day. That really sucked.

Alaska is usually amazing. This time was the exception. Something in the plane broke and had to be fixed. It happens, I get it. So instead of arriving home at 1030pm...I arrived at 3am. Needless to say it was a looooong night. Especially when I got to the airport at 430p for a 645 flight.

The flight was fantastic. All the crew staff were wonderful. Everyone was so friendly and they went out of their way to help make it such an enjoyable flight! I think on such a long flight there should have been some food given. Even cheese and crackers and maybe some cookies!

If the flight from Seattle to Eugene hadn’t been delayed for mechanical reasons we never would have made it. 45 minutes is not enough time to deplane and get clear across a big airport like SeaTac.

perfect flight!! couldn't have been better unless it was free!

Delayed 8 hours, This is the 2nd time in a month that my flight was not on time.

Do not fly on WestJet if you have a connection. It failed to integrate with my connecting Delta flight and I almost missed it.

The experience was good just the upcharge of over a hundred dollars was not cool.

Good, a bit cramped in the seat as my neighbour was a bit large

There was a man who was very rude at boarding. On the other hand personal bag measuring box is too small compared to USA airlines,

The process and flight were both smooth and trouble free

Delays and missed connections were very hard the crew were wonderful but 1 1/2 hours late from Abbotsford to a 4 hour wait in Calgary was too much. I am 79 years old and I didn’t get to my destination until after 1 in the morning. They could have offered a seat in the lounge or a meal. I was very disappointed in the treatment

everything was fine expect massive delays - not the airline’s fault

The checked luggage still hasn't arrived yet. 42 h later. We saw it being unloaded in the stopover location. It was. 5 hour layover so it wasn't a rushed transfer. One positive aspect, it was close to being on time and the crew that came on the clean the plane was very efficient.

Seat back entertainment monitors would be nice. We did enjoy the In-Flight WiFi.
