Flight attendant was awful, I felt second hand embarrassment with every one of her interactions with people onboard. She was so incredibly rude every chance she got

Flight attendant was awful, I felt second hand embarrassment with every one of her interactions with people onboard. She was so incredibly rude every chance she got

Great flight - efficient and cheerful team on board, at SFO gate. Also, PAE (Paine Field, Everett, WA) is a great little airport to fly out or in to!

My flight wait is 3 hours delayed due to Unknown reason. We waited a very long time in the tarmac. Our flight 24 was scheduled @ 7, therefore we left my house at 330 to park our car. We were at the gate @ 530, then we were told at 6a that it will be late , we boarded at 930 but did not take off until 1015. Therefore my arranged pick up in JFK was cancelled because of no show. Before all these I got an email offers of changing my flight to a different date which I took a day earlier. I will never again take Alaska Airlines, very Inefficient and Disappointing.

Such great crew, from checkin to the plane. So friendly and helpful, I was genuinely impressed.

I was sitting towards back of plane and the flight attendants I thought spoke unusually loud for an evening flight. They chatted and chatted all night long and it seemed odd to me that they didn’t try to lower their voices. It is annoying as a passenger to hear all their conversations.

Staff at Gate desk were helpful. My connecting flight from the first part of my trip Kona to Seattle was late. I had to run through SeaTac Seattle to catch my flight to San Jose. They made an exception to let me board. On my return trip San Jose to San Diego and San Diego to Honolulu the same thing happened. One flight arrived late and I had to run through the terminal to catch my connection. There are no Gluten-free & Vegan options meals and snacks to purchase.

Had to pay $8 for internet wasnt cool, no tv’s, had to use phone to watch movies, no food choices seemed available unless u ordered in advance maybe I'm wrong about that but seemed that way, no snacks were served. Seemed a very bare bones flight. But it was on time and safe so that was good

I liked that it didn't take 10 hours to drive here. Super short trip!

Wheelchair assistance was provided in Seattle and was very gratefully accepted. Thank you to the Alaska staff.

We were singled out, greeted and helped with check-in at the busy airport. They offered to take our bags there and gave no fuss when we said they were carry-on. With United just last week I had to put up a fight just to get onto the flight with my one authorized carry-on.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

My husband upgraded our seats and I don't know if it was due to the type of planet was or if they didn't upgrade our seats. We were supposed to be in I believe comfort seats and they were just as tight as any other seat- no leg room and we are very tall people but at least it wasn't extremely cold. My husband did put in a complaint about our seating because he paid extra and if we would have known that the space and the tightness would have been the same, we just would have gotten the emergency row emergency row seats that we normally get. We love Delta but both our flights coming home we're not good. Oh I forgot to mention that on our flight to Hawaii our luggage wheels got broke and we had to purse new luggage on vacation then we never had this problem so we didn't know protocol and reported it after we got home only for them to tell is we only had 24hrs to report the damage. Not sure what was going on with Delta this vacation trip.

Crew was excellent. Comfort seats not as nice as other kinds of planes.

It was a great flight and the stewards and stewardess were all kind and accommodating!! The seats were comfortable and entertainment screen excellent!

There are 4 flights in consecutive gates with about the same departure time. Two flights were boarding at the same time. One was delayed or boarding would be happening at the same time. I am not sure what Delta and LAX need to do to have a better layout at the end of Terminal 2

There was a security issue at the airport and we were unable to land. We circled endlessly and then landed at another airfield for fuel. We then circled the airport again, almost landed but didn’t fully touch down before circling again. I am thankful to the crew for keeping us safe- the issue was the airline and staff at the airport getting us seats on our connecting flights. That part was hours of searching for someone and getting in double my steps.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.
