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.

On time, good seats, not overly full, up beast positive crew.

Airport security lines in Seattle were awful. The only staff that was pleasant and made the trip more enjoyable was the young woman at the gate in Seattle. She was so pleasant and helpful. Flight attendant on the plane seemed like she would rather be anywhere but on that plane.

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

My flight was several times rescheduled and then finally canceled.

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.

People were friendly. Flight was a little delayed. Maybe I missed the reason for it. Overall a nice experience.

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.

The flight itself was great. But we had to wait over an hour to deplane so I missed my train. Not the crews fault. They were wonderful!

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.

Flight was delayed, full flight and I had to change gates. Southwest flights are always late later in the day.

Flight was delayed over 3 hours. Planes were dirty. Staff indifferent. And they serve vegan pretzels as snacks.

It was great. The gate staff were very helpful in Portland when my son forgot his rolling bag and had to go back to get it just in time to make it on the plane. We really appreciate that. Great job!

Airline is not very senior friendly. Flights are late, forcing us to run to the connecting flight. Food is awful. Wish they would go back to pretzels and peanuts. During flight, pressurization isn’t quite right and all of our ears get plugged. Everything is nickel and dime, charging for boarding, seat selection and legroom. While a screen at the desk in the gate area says check your roll on bag now for free due to space limitation, the employee at the desk will not check the bag without a $100 fee. Insane.

Kayak could’ve posted the correct gate number. Almost missed my flight.

Slow boarding, limited food and drink portions. Bad delays and turbulence

there were two flight attendants that were up front...that were the best! They get KUDOs for making my trip only fantastic. Tell them Jeff said that!

OKay. I sat in the back of the plane and it was really loud between babies and little kids, and adults who.like to talk a lot and loudly most of the flight.

Flight coming out of Buffalo was delayed, so we had to be rescheduled on another flight from Baltimore to Phoenix which means we had a long layover and got home 3.5 hours late. Shuttle to parking stopped at 10pm, so we had to pay for an Uber to the parking lot and got charged an extra day of parking since it was after midnight. Not the best experience. Long day!

Was fine, delayed and feels like southwest is always late

Horrible. Faucet in sink not working, wifi not working. Didn’t bring food or snacks

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Gate agent showed up 20 minutes before boarding and was not at all friendly. Had to take this flight due to the one on the day before being cancelled and any later options were already full with long standby lists. Despite having paid for Delta Comfort seats, Delta did not allow me (or anyone) to choose their seat. The agent assigned them for everyone just prior to boarding. Self seat selection was allowed on the original flight. Flight staff was great - very friendly.

Flight attendants were great. Cheerful, upbeat and friendly. Jet, in particular, was fantastic.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

Original flight was delayed, then cancelled and the gate staff did not expedite rebooking. Also, no instructions were given that a ticket number was needed before being called to facilitate rebooking. This could have been much more organized.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Five hour delays every hour, I wish it were all at once

Flight delayed four separate times. I’m now one hour hours late to landing.

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

Crew was amazing, takeoff wonderful. The bathroom was disgusting from before takeoff the odor made the flight uncomfortable as you could smell the bathroom from the center of the plane where we were sitting. Smelled like raw sewage. My daughter was throwing up as we landed due to the smell and horrible turbulence as we approached Newark.

Airline tickets are not cheap. You expect reliable competent service. Thanks to canceled flights and botched transfers we arrived at our destination two days late. This is not acceptable

Horrible! Several delays and then was cancelled! I spent over 24 hours in the airport and was unable to get a hotel or food voucher.

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

This planes staff was top tier. Everything went great and had a great flight home.

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

weather delay of almost 2 hours then we landed and our gate wasn't available so we waited another 30 min

Flight had mechanical issues and it was delayed 30 mins - some of us boarded and then had to deplane.

technology worked well and everything ran smoothly. The seats are quite cramped so please don't try to re-engineer the cabin to squeeze more bodies on board.

Delayed flight more than I hour. When boarding we spent some additional time on the plane before takeoff ....

Flight was delayed due to connecting passengers. Lack of snack options bad. Sitting in Aisle, last cart run pulled the cart directly into my knee. Rude awakening.

We sat on plane at gate delayed without communication as to why we were just sitting there

Agency very bad had to cancelled my booking too many changes in the flight changed my flight to 1 week

Trash. Sat on the runway for 40 mins…missed connecting flight because of it now I’m stuck. Thanks…a whole fkn lot.

The flight was delayed significantly and we sat on runway after landing for awhile. Best thing was the flight attendant, Jenny, in first class, who was very professional and attentive. She was excellent - the rest of the flight was not.

Awfully rude American worker at door when we started boarding flight. Then, walk into a blazing hot airplane with no air conditioning until twenty minutes into the flight. Free entertainment was non existent! My husband, along with the fellow passenger in our row, and I could not get entertainment to work, no WIFI! Really?? Been flying American a long time. Was very disappointed.
