Subject: Formal Complaint – Incompetent Service and Denied Boarding on Flight 1409 (CLSVJM – Dear Alaska Airlines Customer Relations, I am writing to file a formal complaint regarding my experience on Flight 1409 departing from Seattle on 6/13/26. As a physician and business owner who frequently coordinates group travel, this was one of the worst airline experiences I have encountered. Upon arrival, I was informed that my check-in boarding pass was not official, despite successfully obtaining it electronically through your website/app with no warnings or indications of issues. My electronic boarding pass was rejected, leading to cancellation/denial of boarding. The gate agent (an older woman) was unhelpful, claimed my name had been announced multiple times (which it had not—she did not even know my name correctly), and mistakenly boarded my traveling companion under my name. Additionally, an older blonde staff member nearly failed to return my passport, highlighting a clear lack of training on your check-in and boarding systems. This chaos forced me onto a later flight while my group waited in Canada, unable to check into our Airbnb or pick up rental cars (as I was the primary booker). The entire incident caused significant business disruption, stress, and additional expenses. I have flown Alaska Airlines previously but will not consider it again without resolution. I request: • Full reimbursement of any additional costs incurred. • Appropriate compensation (vouchers/miles) for the inconvenience and poor service. • Confirmation of corrective actions for Please respond within 7-10 business days. Sincerely, Dr. Chunwen Teng

Never had so many staff members be rude and disrespectful. I had a staff member sarcastically call me “girly” after making me wait 20 minutes to be seen by her. I was able to print my luggage tag and she told me I was too late to check luggage I said the system obviously disagrees. And you had me wait way too long while you asked every single passenger ahead of me about their Disney vacations. She wasted so much time to then say “girly your bag won’t make it on the plane” I’m not her girly I’m a full grown adult. She needs to learn a hell of a lot of respect

The agents were super helpful. I was traveling with my mother inlaw who needed whell chair assisstance. The help and accomodation from the checkin crew, to the boarding crew and inflight crew was excellent.

Completely full flight. Boarding was smooth, but people didn’t listen about use of overhead bins which is typical. We pre-purchased a snack which was tasty. Drinks were good and plentiful. Flight left late because previous flight was delayed.

Flying into PAE was so easy because it’s baggage claim is quick and accesible. I had a car rental and the counter is inside the baggage claim area, very convenient.

Eva Airlines attendants were wonderful. I really enjoyed the hot meals. They always greeted me with a warm smile. I'm looking forward to flying back to the USA with them again!

Flight maintenance was on so that flight didn’t go able to fly out to Seattle and Inhad to get another flight,,

Nice to get moved from a middle seat to an aisle seat upon request, but why wasn’t I put in an aisle seat to begin with? The flight was not full.

The merging of Kayak & the airline’s website was not always clear. Both on their own provided adequate Information about the flight. I had some challenges retrieving the boarding pass. I relied on the agent & may have paid the baggage fee twice.
