There was a delay, then we were boarded, then deboarded, then waited another hour for a new flight, then boarded again and arrived 2 hours later than expected while traveling with 3 young children.

I don't like that this survey shows Good for everything. Everything was not Good. I didn't eat any of the food. I didnt' have any entertainment. You need to have a NA choice. My flight was satisfactory until I debarked the plane and fell on the Jetway. The jetway sections had a slight inclined edge, which I tripped on. I was near the plane's exit door, but neither of the flight attendants helped me get up. I was helped by two other passengers. Also, I explained to the counter staff about falling and no one seemed to understand what I was telling them. I said I fell on the ramp, which was not the correct term. The passenger who was sitting next to me on the plane did a better job of explaining to your staff where I fell and that I was in a lot of pain. I also wanted to report the incident and no one helped with that. I was then offered a wheelchair. The passenger who helped me stayed with me until the wheelchair arrived. I asked the wheelchair attendant if there was anyone I could report the incident to and he said there was no one. Really???? My daughter picked me up at the door. I tipped the attendant for his service from the Alaska counter to her car. Before leaving the property, my daughter called the airport to report the incident. We were advised to go to the to a hospital ER. A Cat Scan showed I broke the 6th rib on the right side. My daughter was sent paperwork to complete from the agent with whom she spoke before we left the airport.

Flight attendant was excellent, pleasant and attentive. Announcements were clear and pleasant.

seats good, foot space comfortable not good, waiting on tormack at Las Vegas

6 hour flight from Seattle to Dulles airport without any WiFi and movies, as well as now snacks is crazy. We were told no WiFi and entertainment 5 hours before departure.

Wifi would be nice. Unfortunately the particular airplane was not equipped with wifi.

I'm so glad that Alaska still keeps this little "puddle-jumper" route going between SEA>ALW; my daughter lives on Walla Walla, and it's so much quicker to be able to fly right in to Walla Walla than to have to fly into Tri-Cities and then make her drive 40 minutes each way. This flight is usually only 50%-75% full when I fly it, but that's because it doesn't get in to ALW until MIDNIGHT! But thanks for continuing to service the Walla Walla area, Alaska!

Seats very comfortable and legroom appreciated. All in all, it was a great experience.

Original flight was canceled, and the automatically booked second flight was immediately delayed. I arrived about 4 hours later than planned with only a $12 meal voucher that didn't fully cover a sandwich at airport prices.

I was expecting better service from Alaska Airlines. I registered for assistance since I have a disability. The terminal in Seattle, WA was very unprofessional and at times rude. The BWI location was the exact opposite. I will NOT consider Alaska Airlines for future flights.

I was traveling with my two young children and brooked this flight as it was the best option. There were no screens for movies etc. which normally would be fine, however, when you list free in flight entertainment that should be mentioned. We don't rely on them but count on it as a worst case scenario backup for the kids to keep the peace if needed. The main issue though was the food selection. I have dietary restrictions so I was excited to preorder meals. Nothing that was offered on board or for preorder was ok for me to eat, not even the snack boxes. It was very frustrating for a 5+ hour flight. Otherwise the flight was good and went smoothly.

Usually we have a pleasant trip on HA. Not this time! All stewards were unpleasant, rude, rushed, condescending. First step onto the plane, WE greeted the crew with an “Hello!”. They greeted us with a terse smile then ignored us. Not a good start. Even over the PA announcements, they were rushed and unpleasant. One Stewart even berated a passenger in front of us when all they asked is if the purchase cart had vodka to purchase. The steward said “LIKE WE SAID OVER THE PA, THIS ONLY HAS FOOD OR BEVERAGE!” Vodka is a beverage! It was a legitimate question. Not sure why she treated the passenger this way. Taking trash was even unpleasant, No “Thank you” or at least a smile. I work in CS. I know good CS can make or break your trip. There was absolutely no “aloha” on this trip. All clearly did not want to be on this plane and felt strongly that they did not want to provide a premium service to their clients. This might be our last HA and cancellation of my HA-MC if we are treated the same way going home. We are typically treated with kindness and warmth in the past with HA. This trip was unacceptable.

Plenty of overhead compartment room. The seat choice option is horrendous as best.

Really disappointed with in flight entertainment, 6 hr flight with no built in screens

I was put in a middle seat with the people on either side of me kept passing their grandchild over me and talking back and forth while I was trying to rest or watch a movie. So inconsiderate and totally disturbing. I asked if they would sit next to each other to alleviate the constant impeding my comfort but they refused.

The flight crew were great. Very helpful and friendly. Seats comfy. Thanks

Overall it was a good flight, but the food should be looked at. No options. The seat was also uncomfortable and very tight.

Late boarding, full flight. Absolutely no food and barely a bag of pretzels. No video screens and slim pickings of movies. No live tv and poor selection of shows.

It’s great, I’ve always fly & ride with Hawaiian Airlines going Inter island or to the mainland.
