Melissa provided exceptional service!

Ticket agent Kamiko in Seattle was wonderful. She went out of her way to get me my flight

Alaska has always been good to and for us. As with all airlines now, always read everything carefully and expect pricing to fluctuate.

Nov 14, 2019

The flight was good. My only comment is that it was a little concerning to hear the pilot advertising a credit card instead of focusing on flying the plane.

Love ALASKA AIRLINES!

Nov 13, 2018

The seats are okay in terms of comfort, and the leg room was decent. The staff was fantastic, though! Everyone from the check-in staffer and the gate folks through the flight crew was so kind and personable. However, if a customer indicates when buying the ticket and checking in that they have mobility issues, consider assigning seats NOT at the back of the plane. Row 31 is a row too far after a long flight with stiff and painful legs. Still, the pros well outweigh the cons, and I'd fly Alaska again in a heartbeat.

Staff helpful when someone else took my carryon bag

We booked together as married couple. Were placed in rows 11 and 12. Would have been nice to be in same row.
