I had to change my flight last minute due to a medical emergency. Their agent was compassionate and extremely helpful. This airlines really cares about making travel, for fun, work, or an emergency a customer-focused experience. Thank you!

No issues and clear sailing. What a preferred to have sat in one of empty seats other than my assigned seat that would be my only complaint if it was to complain.

They cancelled the flight and provided no support to find another way home or how to get a refund. Links provided didn’t work and phone wait times were over eight hours. Battery on my phone couldn’t last long enough.

Due to plane delays on both legs of my flight home, I had to be rerouted from Santa Rosa to Las Vegas on Skywest and then to DCA on American. SkyWest airlines sat on runway in Las Vegas for 20 minutes waiting for gate to clear. My boarding pass for American that I was given by Alaska was incomplete and the Las Vegas airport lacked signage and departure boards. I barely made my flight bc it was so confusing. American Airlines has a much better wireless connection. I’ll never fly Alaska again. It clearly has problems.

Flight was delayed two hours; for an hour and a half flight?! And so we missed our connecting flight to Rome because of the long walk between the terminals. Hoping to hear back from Alaska about some compensation for our missed flight and night stay in Los Angeles.

It was my first time flying Alaska Airlines and first time flying from Santa Rosa airport. The staff was very professional and friendly. Their instructions were clear and any question was answered satisfactorily. My seat was comfortable and the in-flight beverage service very adequate for the duration of the flight. We arrived ahead of the scheduled landing time and deplaning was simple. I look forward to flying with Alaska again.

I’m New to Alaska Airlines. I was not able to connect to WiFi on either leg of my flights to/from Santa Rosa. Otherwise, it was an enjoyable ride.

All good. Great food and entertainment when there isn’t any on a one hour flight

The first flight attendant who served refreshments was not pleasant at all. No eye contact, no smile, I used my “please “ and “thank you “ and all but had pretzels thrown at me. Next one far surpassed pleasantries and more like Alaska Air! Good leg room, comfortable seats. Boarding was without flaws. I didn’t order food….

All was good. Flight from STS to Burbank was on a new plane; flight back was on a plane that was showing its age.
