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

My flight was several times rescheduled and then finally canceled.

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.

It was a very short flight so there really wasn’t any entertainment my. The little pretzels were good though and the cabin crew was awesome.

The first flight was fine, great crew, but the plane was delayed 45 minutes to go to Seattle because of they were missing a ramp. That would make sense if the plane was actually at the gate. Not if we’re still waiting for a plane. After we landed we waited 30-45 minutes on the tarmac just to get off the plane. Alaska made me miss my connecting flight, wasting my time, and my money. I should honestly be reimbursed, but hey, when does the airline ever actually take accountability? Never.

Over all it was great. My original flight was canceled but they quickly rebooked me. I was frustrated because I had to cancel my entire plans for the day but all considered, not bad. The crew tried to keep us calm while we sat in the plane for was felt was an hour or so but they could use a bit of a script. The seats were comfortable and I would give it another try.

Flight delayed Didn’t send second leg of trip itemerary First class was fair, but not great.

Short trip, was nice to have a drink on the short flight still.

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.

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

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.

Read the fine print. This was my flight home. I booked my flight for the quickest way home. Had a carry-on and a personal item. Same as my outbound flight. Apparently I needed to pre-pay extra for my carry-on. When I checked in, I was told that I had to check it. I said I’ll pay for it, and was told that this wasn’t an option anymore. They said I still had to pay $50 to check my carry-on. I told them I’ll pay whatever to just carry it in as intended. I was not allowed, so eventually I paid $50 to check my carry-on under a plane that was half full, with overhead compartments that were even less full. My white carry-on suitcase was practically destroyed getting from Idaho falls to Denver to Orange County. The low price air fair was a bait and switch. Got me to the gate, made me pay extra, then didn’t even allow me to pay for a carry on. Not to mention that I paid the $8 for WiFi that didn’t work. All to get my suitcase destroyed. I don’t think I’m going to even keep my Untied mileage plus membership and card. Apparently, membership does not have its privileges for this one.

I flew from Santa Fe to Denver to catch a flight to London and the transfer of my luggage on arrival at Denver to the London flight worked perfectly. The crew on the ground and on board for the London flight were so friendly and efficient.

Late- that’s what United does best. Missed my connection, rebooked to a flight 17 hours later and had to spend $500 on a hotel. What did I get? A $15 meal voucher. What can you get in an airport for $15. I hate United so much.

It was good overall except from Omaha to Denver when flight a was a repeatedly delayed apparently due to some issue at Denver. Communications could have been handled better. I had to board then deboard with luggage and board again

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

They told us yesterday APR21st that they were cleaning the plane and we got delayed. After that they said they didn't had any crew for the flight so they cancelled the flight till next day.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

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

The gate experience at LAX was abysmal (same for the arrival experience two days prior). Despite the LAX -> SAT schedule of two flights daily, our departure gate was at a smaller hub that we had to be bussed to from Terminal 4. Fortunately, I arrived at LAX extra early and had time to spare, but if I had not known, I might have missed my flight. I looked at the LAX airport map in the AA app and there was no indication of the additional boarding process. Lastly the gate area we were bussed to was crowded with limited food and beverage options. On flight, the fight attendant was hospitable and attentive, the flight was smooth, and AA's free (and working) wifi for AA members were all on the positive side.

Our flight from JFK to Madrid was delayed. We had to go from one side of the Madrid airport (Terminal 4s to the far end of terminal 4 - Gate K98) to our gate in less than 30 minutes. Put passport control and security/baggage check and that’s very hard unless you’re Usain Bolt. I called Iberia Airlines and the telephone customer service told me that I was going to have to pay to re-book. Luckily the help desk in the airport (who was dealing with dozens of people from the same JFK-Madrid flight) did not charge us extra to reschedule to a flight 8 hours later. They also gave us a voucher for breakfast and lunch. Glad the actual person at the airport had some actual sense.

Take-off delayed an hour because of a missing flight officer, so,arrived in Charlotte lates causing many passengers to miss connections. Otherwise a very good flight, safe and comfortable, with an excellent professional crew.

The flight from LA to Chicago was smooth and service was very good overall.

Ontario airport boarding was very easy to park and access, is clean and TSA took 10 minutes total. Check-in was a breeze and cruise was very nice.

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

Boarding gate at LAX was too crowded—two gates next to one another

On time departure and early arrival. Flight attendant very nice.

Everything was delayed and the staff sent me to the wrong gate, causing me to miss one of my flights. I arrived at my destination 6 hours later than I was supposed to.
