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

A solidly good experience, but would’ve appreciated more communication with regards to travel delays.

The plane not having any overhead bin space was inconvenient. Anytime my luggage has to be checked it ends up covered in scratches and that’s not covered by the airlines for replacement/repair. The WiFi did not work or was not offered for the flight from Seattle to Vancouver.

The seats were not very comfortable and there were no TV screens. Boarding was pretty fast because there were so few people on such a small plane and I appreciated that they still gave us our snack and drinks, however I really wish they would come up with a good gluten-free snack.

Everything was really good except it was really cold in the plane,

Our flight experience started at the check in kiosk. Jennifer  Polete smf 498304 greeted us and assisted us with our tags and check in guidance. She was so pleasant, helpful and friendly. This was the start of my experience with American Airlines and it made such a wonderful impression. The staff on the airplane were also kind, courteous, and attentive. I would definitely fly American Airlines again

Overall good. Good communication from the captain on delay, cozy seats, nice staff, and a perfect landing.

Overall a good experience, just a bit of a cramped and old aircraft

Easy checki in and boarding. VERY clean seats and excellent service.

For a red-eye flight, it was overall okay. My biggest complaint is that my seat recline was broken and I paid more for a premium seat. That was disappointing.

The WiFi wasn’t working, so no one could watch any entertainment for 5 hours. The plane also was delayed and did not leave, nor did the staff prioritize those with connecting flights to de-board first. Everyone with a connecting flight to Munich missed their flight by 5 minutes. Then the next flight to Munich was 14 hours later. The airport could not compensate us because the closest hotel was about 2 hours away. This did not seem like the truth. I was not pleased with this traveling experience.

I DO NOT recommend Iceland air...missed connecting flight.....paid for isle seat upgrade for health reasons...had to do that over....baggage left in the rain so clothes got soaked other items ruined....called customer * dont care* service

Damage May baggage and I report the airport agant and they see it

Crew was very friendly. Need lay flat beds! More snacks

Good. Rxception is the Entertainment - movies and TV shows all out of date…

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

They cancelled our connecting flight resulting in another layover reaching our final destination 8 hours later than scheduled.

On-time arrivals and departures. Crew helpful and friendly. Yet everything costs extra: seat selection, food, even airphones!

Second time with Saga Premium, everything was fab, but the entertainment centre on both my flights didn't work, plus the seat on the NY to Rek flight (Airbus) was so solid and so uncomfortable. The 737Max flight's seat was much, much better.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.
