Overall it was good. There was a delay in departure, which is why I did not rate it as excellent.

Overall it was good. There was a delay in departure, which is why I did not rate it as excellent.

delayed flight 3 hours, then took 45 min to get to gate and another 10 min to open door

The plane was put out of service and had to wait for a new plane to be assigned. No one had any information and the information on the screens was never updated. The call wait time was 2 hours and the estimated time for text assistance was 55 minutes which was a lie because after 55 minutes nothing happened. I understand that delays happen but to not have anyone available to provide any update or reassurance was just negligent. Also, what is the point of having an 800 number if no one answers it and don’t get me started on the text message system. Ridiculous!

Very expensive for short flights. Can’t communicate with Alaska Air about passport issue at check-in. Also no replies to my text messages. Wanted to extend our vacation for two more days but this expensive flight ticket is called SAVER and I couldn’t make changes or cancel or get a credit even, so I paid another airline for the return trip. Extremely disappointed.

The flight was canceled at the last minute and we got very upset as we had plans in which our schedule that affects a family reunion was in jeopardy.

Paying for first class and then they want $8:00 for wifi.

fine. only problem,,,, for some,,,,was that many people started trying to exit from the back of the plane,, . lots of irate people. there should be a flight attendant mid plane..to be sure that doesn't happen. The crew up front had no idea what was happening. One big guy started it..then a bunch of others followed his lead. could have gotten ugly... One man stepped in and questioned those rule breakers.. nothing bad happened,,,but......

Eddie, our flight attendant in the back was excellent. He was very kind and concerned for our happiness and comfort before and during our flight. He made the experience great. We had to deplane due to a ground delay and he made sure we had snacks and water to keep us comfortable while we waited. Overall, it was a great experience!

Flight was delayed which caused us to have to change our connecting flight. Grilled cheese sandwich was served very hot.

We were late so that was what was worst part

Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.

No trays in our seats, we sat in first row, purchased a business class fare. Had to hold our drinks and snack in our hands. No plugs for our cell phones. Had to pay for it a drink cocktail each. Seats so uncomfortable.

Flight wasn’t even full, but too many carry-ons caused us to run out of bin space. New bag fee has folks who would usually check their bags carrying on. Watching Southwest morph into Spirit/Frontier is so sad to watch

Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.

I would have liked to arrive on time - not 5 hours late!

It was a perfect flight in all aspects! Both legs!

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

I liked the crew member who gave flight instructions on "in case of a problem:. The seats are so small that only a young teenager could sit in middle seat.

Great flight staff. Ease of boarding. Overall, very uneventful and easy trip.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

Delayed and took off even later than the scheduled delay time

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.

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

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

Departure was two hours late! Better than four hours late on our first flight

The flight was supposed to leave at 7:30pm, but departed 10:50pm. They kept moving departure time out every half hour. It was a 45 minute flight from n Sunday night with great weather.

Flight got delayed and it was very inconvenient . Had to come with another carrier. Had to spend one more night in San Francisco.

Logging into next flight was an issue as I never received a confirmation code

Everything was good for the price I paid. Crew was very nice.

The worst flight experience I've ever had. Our flight was delayed 14 whole hours because the flight crew never showed up. We had to wait in a two hour line to get our new boarding passes, we were told we had no other option but to fly at 10pm (we didn't depart until 11:45pm). Everyone had to contact their hotels and car rental places, workplaces, etc. since we lost an entire day's worth of travel. The crew showed up at 10:15, which was past the time we were supposed to board. They were laughing and being completely smug when they boarded, and they took another hour to board us onto our flight. The flight crew never came to check in on us, we were quickly given one drink and sandwich and they turned off the lights and were negligent the rest of the trip. My mom asked three attendants for a seat belt extender, they never brought one. I was dehydrated and never received another drink. They were very rude and unfriendly, we had been up since 4am the morning of our flight and didn't land in our destination until 2am the next day (5am local time). This was unacceptable service and treatment, these flights are not cheap and we were inconvenienced out of an entire day of travel. This was 100% avoidable and was the fault of Hawaiian Airlines, and their crews inability to show up to work on time.

Loved the leg room, usb charging, outlet, food, staff. The seats were very uncomfortable for some reason and made my buttocks ache and would have liked to be seated together from the time of purchasing tickets without having to pay extra.

My confirmation number did not work to check in the day before, so I had to go to the very busy line (no kiosks at the airport) and almost missed my flight. Also, no one told me that I had to actually check in with Alaska

I was put in seat 6B with no warning. Had no seat in front of me just sticks out in the aisle so I had to hold what I could and put the rest in a bin way further down.

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.
