The plane was freezing. A few other customers mentioned how they can’t get their temperature right on their flights lately.

The app booked me on a flight for July 1st as opposed to August 1st like it was supposed to be. No problem with Alaska Airlines, except they took a while to refund my money. But it was as taken instantly. So, yeah.

Not able to get boarding pass for domestic connection flight when check in at international airport. I was told I need to get connection flight boarding pass after I entered US. It us very inconvenient.

Flight delayed no communication. The gate was changed so many times.

Four hour delay. Missed our event. And they offered me $75. Absolutely shameful.

I have been flying commercial for decades. I was in one of the ladder boarding groups, had my bag tagged because they thought there was not going to be enough space for it in the overhead bins. I politely asked one of the attendance if I could try to find a space- she said I could and I did. I then took the bag tag off and gave it to one of the other attendants as I was told to do by the first one. He, in a curt, anal, and disrespectful manner, told me that I needed to take my bag down from the overhead bin and check it. This was a situation I’ve never encountered before. The attendant’s attitude was confrontational and belittling in front of other onlooking passengers as if daring me to challenge him. I am a physician who takes care of patients day in and day out. Not wanting to make a scene, I calmly told him, “do what you need to do.” he took my bag down from the overhead bin, put the back tag back on it, and checked it only to make room for another bag that was also supposed to be technically checked by a following passenger. The same male attendant later came up to me and said “you shouldn’t have showed me the bag tag,” as if conveying that he was just following protocol was a justification for treating me like a kid out of line. I cared about this because it took 15 minutes from my life to then retrieve the bag at baggage claim and it also felt like really poor customer service. I understand the need for protocols. This is also a service industry, and we the passengers are the clients. We should be made to feel welcome and respected and our life in transit made as easy as it can be within reason. This attendant clearly needs to be reminded of that. Of note, an older female fellow passenger sitting next to me agreed with this assessment.

I can't say yet as I'm still waiting for my luggage. I thought I had given my TSA # before my first flight but it wasn't on my boarding pass so my initial flying to my destination I wasn't able to utilize the device. I called Alaska Airlines and had it added to my profile. It still wasn't on my boarding pass so I had to go to an agent and have it added which took extra time as there was a line of people waiting to be helped.

The lady who was checking people in and scanning tickets was very sweet. I believe her name is Ilhad…real sweety. The flight sat on the tarmac for a good 20-25 minutes with no explanation still we weren’t that late but they should communicate to people why were not moving.

This was a quick flight so more like a shuttle and everything went well. There was no food or beverage.

Planes are too cramped. How far are the airlines going to go before Congress steps in.
