The messaging about the change in flight destination and options for getting to SFO was poor. There should have been frequent updates. When I spoke to the boarding agent moment before we were supposed to board, he was flippant and offered no help before the announcement was made that transportation would be arranged. It was as poor of an experience that I've ever had.

The messaging about the change in flight destination and options for getting to SFO was poor. There should have been frequent updates. When I spoke to the boarding agent moment before we were supposed to board, he was flippant and offered no help before the announcement was made that transportation would be arranged. It was as poor of an experience that I've ever had.

My plane ride down landed 20 min late. Boarding at SFO was strange too. The people at the terminal were nice—but, boarding lacked direction, and was confusing . Coming back was worse—the plane was hours behind—and I barely caught the last Bart train back to San Francisco (3 min more and I would have been in trouble). It was a very stressful trip, and it didn’t need to be.

This leg was better than the previous leg mostly because I upgraded my searing and the crew was nicer

I like that we took off on time and arrived a bit early. I like that I could gate check my bag and board early. I don't like how crowded the flight was. I had ok leg room, but could feel every move of the person next to me. And the aisles are very narrow. The gate and flight crews were terrific.

I appreciated the ability to choose between multiple flights both into and out of Portland from Burbank on the same day, so we were able to attend an event and return without spending the night. I am unable to appreciate what Alaska Air calls "streamlining" the checkin/boarding process at Burbank Airport. If you have a smartphone and the Alaska Air app, it is probably fine, but removing the option of using onsite kiosks to print boarding passes does not meet my definition of "streamlined". I also found it challenging that both Portland and Burbank airports required the plane to sit on the runway for some time due to lack of an open gate at which to disembark. It would not be so bad if we could at least remove our seat belts and move a little bit while we waited, but that is not an option. I honestly don't know whether this is because of how Alaska Air operates, or just the circumstances of the particular day and airports we were using, but I normally do not experience these kinds of delays to reach a gate using Southwest Air.

This flight was significantly affected by poor wifi connections. I couldn’t get my work done because the wifi kept dropping. Even texts were not going through. There is no seat power in premium class either. I fly a lot. Today was my 10th flight in 4 weeks. This was by far the only flight that was sub par.

the departure got delayed due to SJC situation, but it was a quite good waiting thanks to Alaska airline teams.

I was not given a seat when I bought the ticket. I know airlines are trying to squeeze every penny out ot the customer, but we are buying a seat on the airplane, right? I find this irritating with all airlines, but especially Alaska because I fly it so often. No sense of customer use and loyalty.

WiFi connection bad. Food is really awful. Crew very nice and efficient

It was the worst experience because they delayed the flight by 2 and half hours. We were supposed to depart by 3:41 but they did the depart by 6 pm. It was so boring!!

There was a loud squeaky sound the whole time we were flying.

I didn’t not like that I could not select my seat and ended up with the worse seat.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

The seats are too hard for long flights but otherwise- the process was smooth, the staff attentive, and there was to keep you occupied during the journey if needed.

Plane was late because of a mechanical malfunction and the food listed as available was not. Flight attendants seem over worked and under paid. They just done seem happy. And that can be seen in their faces.

Waited 3 hours on a plane to de-ice due to manpower issues. Waited another hour and a half once we landed because of a gate issue. Missed my connections. Created. A total of 13 hours of delay.

Flight was on time and in fact arrived early. Seating was as comfortable as you can get in coach. Adequate leg room. Good entertainment system and offerings. Food was good. Flight staff was very good and accommodating.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

Like most domestic flights in the US, you are basically on your own with this airline when it comes to food, so be sure to purchase meals and drinks ahead of time or expect to arrive starving and dehydrated (like I was).

This flight was delayed approximately 4 hours due to bad weather in HNL.

Flight delayed then cancelled then gate changed two times then baggage lost.

The plane is extremely loud and there’s no place to charge devices.

Not great to be very honest. Our flight was delayed after we sat at the airport until 15 minutes after we were supposed to leave . We were then notified the plane was being worked on “and the parts were out in the ground and still not finished .” Even though the work started the evening before and they knew it wasn’t fixed. . Then we were told it would be a 1:15 pm boarding time so we waited then at 1:45pm we were told it would be an 11:15pm boarding . It was changed to and 3:55am boarding the next morning . We lost out on a day in Hawaii and a night of our VRBO rental.

Love the food service and attentiveness of the crew. Could have wi-if on flight

Our first experienced in Hawaiian Airlines was just okay. I traveled with my 2 year old and 5 year old and both kids are first time in Kona. We had delayed in San Francisco for 3 hours which is okay safety first. Originally our flight from sfo to maui to Kona since we had delayed the airlines re-route us from sfo to maui to Honolulu to Kona. I don’t know what to do I felt bad with my two kids they have been in 4 Airports and 4 airplanes going to Kona. I cried after we checked in at the courtyard Kona. It was a lot for my 2 year old and 5 year. Like I said I know it is safety first but the Airlines could have done better for people that traveling with kids. If you are in my shoes all what will you do? Anyhow, I tried to make my two kids as happy as possible while we are in Kona. I am not certain to fly Hawaiian Airlines again. I hope my experienced helps to improve whatever it needs to improve With all due respect, Christina Lorenzo

Nice. The chairs were a little uncomfortable. And the sound from the earbuds I purchased on the airplane didn’t work very well. Other than that it was a great flight… oh and the snack could have been better… a bag of peanuts would have been better.

Our flight to Lihue was cancelled two times so after paying for baggage etc we had to go to seattle wait a couple of hours and then to Lihue. What should have been a five hour trip took over 10 with two kids and four adults, frankly it wasn't fun. The trip home was ok but seats are very cramped . I just wish we could have spoken to somebody who would understand what a hardship this was on our family vacation

They canceled our scheduled flight. We flew back one day delayed. The company won't give us any compensation for the delay 😒.

Staff was amazing during flight. Overall the actual flight was pretty good! But a couple not so great things: I couldn’t get the entrainment to work on my devices. We showed up over an hour before departure and the lady at the gate told us the flight was boarding, and “good luck” making the flight bc it was the last gate in the terminal… everyone was running frantically trying to make the flight. Also, bag didn’t make it to Lihue. It was delivered the next day. Which was a major bummer, had baby formula, diapers, and a lot of important stuff that can’t be purchased it Lihue. I get it happens but it’s still a huge inconvenience… lady at the counter couldn’t have cared less, offered no apology.

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Awful. I got stuck next to a person carrying a dog and behind someone with a dog. People need to board these dogs downstairs. The cabin is crowded enough with your pets

Packed in like sardines, very uncomfortable. Sitting the aisle my shoulder was rammed into numerous times by rushing flight attendants. Also flight was very cold.

the head jack on my seat didn't work and the power outlet didn't work for my seat

Left 2 hours later for delayed I had to take care a kid with special need since people don’t want to move to accommodate the rest of the family. . It wasn’t bad but that made me upset that people can be that selfish.

The leg space between me and the seat in front of me was excellent.

For a 22 minute flight all you expect is for it to be safe and comfortable

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Comfort of seats, ease of boarding. Food selection could be better

Food options were limited which is absolutely embarrassing for a Flight of this size The staff did not come around as much and I am not accustomed to such poor service from American Airlines Drinks I believe were limited to soda and water

Crew were attentive and friendly. Flight was smooth and early! I enjoyed the less crowded plane. Thank you!

We are gluten free, there were not any available complimentary gluten free options.

No meal on a cross country flight? SFO-MiA is pretty much the definition of a coast to coast flight. No meal provided. Sky high wi-fi rates too. Stop nickel and diming your customers.

The staff was unprofessional and didn’t communicate very well. The boarding process was very disheveled, potentially due to a power outage the previous day but there was no contingency plan to properly get passengers boarded the following day. Once boarded the aircraft stayed on the tarmac for over 45 minutes due to high winds. The communication was sporadic but an announcement was finally made an additional 30 minutes later that the flight was cancelled but we couldn’t get off the plane. Prior to deplaning one of the gate agents came on the plane and made an announcement for everyone to pickup their checked bags and take a card to rebook a new reservation because they didn’t have adequate staff. Flights were missed, passengers went to different airports and there was little to no assistance from AA.

Apart from the delay due to unforeseen circumstances. The leg from sjc to dfw was fine. It was the leg from dfw to orf that we encountered issues mainly due to the flight attendant crew not being friendly. We had two small children and we needed some assistance to warm up milk so the baby would sleep. The crew just didn’t get it and made things very difficult. One made a remark that the baby’s dirty diaper smell was a “gift” to the plane in a rude way. Normally I’d brush that off as a funny comment if the rest of the trip the attendants were helpful or understanding of the difficulty we faced. But that wasn’t the case. We were met with rudeness on the second leg. Whereas on the first leg the crew were so nice and helpful.

Flight From PHX to CVG was on time, very professional staff

Being back games on the in-flight entertainment. Also your flight attendants need a break, raise, or overall attitude adjustment.
