You need a n/a category. Too short a flight for food. I love flying on Alaska from Santa Rosa Airport!

I didn’t order food so can’t really say how it was. Overall, it was a great experience.
I recently traveled with my service animal, and before boarding, a gate agent kindly arranged for me to have an empty seat next to me to give my dog more space. However, once on board, a male crew member spoke to me in a rude and loud tone, insisting my dog stay on the floor or my lap—even after I explained what the gate agent had approved. His tone and behavior were unprofessional and made me feel uncomfortable in front of other passengers. I understand and respect airline policies, but I would appreciate if this could be reviewed to ensure better awareness and sensitivity toward passengers traveling with service animals. Thank you for your understanding.
Kayak I had marked one carry on, one checked bag. Yet when it completed the purchase marked it as no carry on. Fail on kayaks side! Then extended flight delayed due to computer issues. Crew of the plane did awesome but fail on both kayak and alaskan
Glad they offer free meal, & I got a complimentary drink I’d like coffee,tea, or water offered 3/4 into trip
Terrible. My flight was pushed out three times finally the fourth time it was canceled completely. They sent me to a hotel that would not accept the voucher. And I had to pay for my cab and Uber . I arrived at the airport at five and didn’t get into my hotel until 1145.
I liked that internet connection while in flight was available.👍
Great if it’s not a long flight in coach.
Seattle airport terminal was a nightmare to navigate. Coming g off a cruise boat etc. Lack of convient Restrooms a major issue. Once able to get to boarding Alaska Air it was good experience.
Appreciated the upgrade on the saver ticket. Made the 5 hour flight bearable.
Crew could have been friendlier, maybe I'm spoiled by SW crews. In flight wifi was good. Would be nice to have more food offerings on a 4 plus hour flight
Ever since Southwest starting charging for bags, passengers don't want to pay to check their bags, so the gate agents have to beg people to check their roller bags now because there's "not enough space". This was a terrible business move by Southwest.
Sacrament staff are always polite and helpful. Airport is easy to maneuver and boarding is straightforward.
As always, the entire Southwest experience was wonderful, from online booking to flight to baggage retrieval. Very grateful.
The weather could have been better. There was a 40 minute ATC delay in SFO because of marine fog and a micro cell storm delayed landing and take-off at Nashville. The gate was changed 5 minutes from boarding from gate B3 to gate C23 at Nashville airport.
The cabin was quiet for the redeye flight. The area was clean. The staff was great. The 787 Max was in good condition. Drawbacks were that the seat widths were tight for some passengers. The seat padding was at best average and for a long flight uncomfortable.
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 received several emails about my 3:10 flight. When I showed up to the airport at 12:30 to check my bags I was told the flight was actually at 1 pm. They grudgingly rebooked me for a flight at 5:22 to Vegas to get a connecting to LAX. I did find the gate for my original 3:10 flight but they were booked. I proceeded to receive status updates and gate change information for the 3:10 flight, even though I was apparently never supposed to be on that flight
The food options were limited and very specific. Some type of entertainment option for a 4.5 hour flight would have been nice.
Flight was smooth and comfortable. We were able to check a bag at counter due to full flight and boarded with an earlier group. We were there very early and didn’t hear the gate change just noticed our flight was no longer displayed st the gate. There were two other flights with gate shuffles - may be unavoidable but not desirable. First time I had to print my own luggage tag and attach at arrival. Not a fan of that process.
I received an email from Kayak with confirmation number for Hawaiian and another for Alaska. I received emails from Kayak for both my outbound and return flight to say "time to check in." Despite trying each number (Hawaiian and Alaska), I could not check in for outbound or return. It was then confusing at the airport - I hda "no place to go" to figure out how to check in. All the kiosks are marked "scan bag,etc." I wandered around with no agent to talk to. That was a bit stressful. Either Kayak, or airline, needed better communication on what to expect and to do.
The Kayak confirmation number did not work for checking in the day before. I checked in at 8.30 using my ticket number. When I arrived at the airport, I was informed that the flight was overbooked, and since I had checked in late, I did not have a seat. The Next flight was not until ten PM. I called my wife, who had been taking care of our kids all weekend, and she was upset, calling me a liar and telling me to stay in SD. It turned my weekend getaway into a nightmare! I blame the Kayak website and will not book flights using your app in the future.
comfortable but the food is horrible. I have flown Hawaiian several times now and no matter what they say the food is its the same squashed bread with melted goop inside. Tastes fake and isnt what they represent, its quite nasty. What happend to real food? And there is NO entertainment!! so not sure why they are asking for a review on that.
Good and friendly staff. Nicely enjoyed the complimentary drink and snack.
I was very, very cold and a stranger loaned me her sweater next to me. I didn’t wanna buy a blanket just for a four hour trip when I did not need the pillow or the earphones. I don’t mind purchasing a blanket, but I only needed that not all of it accessories. Cold air pretty much blew the entire trip. Two people in front of me both bought the blanket packages. Maybe that’s the idea. The crew was exceptionally nice and passed through multiple times.. the restrooms were very clean and usually accessible.
3 hour wait on customer service after flight was cancelled. Was bumped to a flight where I wouldnt have gotten to my destination for another 2 days. Had to fully refund flight and book a new one the following morning. Paid twice the amount for the flight than I had originally booked. Very disappointed I was not offered any sort of discount or points for all of the frustration, in fact the airline profited twice as much off of me by cancelling my flight and and changing my entire trip.
I understand that both Hawaiian and Alaskan are in the process of merging but I could not get real-time flight info or access my boarding pass on either app
Great crew, excellent landing, good food. Over all great experience. Thank you!
One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.
Not pleasant trip cross country when the entertainment and WiFi system not working. No entertainment for entirety of route. Staff was rather nonchalant in that they dismissed the problem due to age of plane. It would have been nice to know this up front so I could have come prepared to read or download movies before boarding Coincidentally or not, there was a similar issue with the entertainment system on my previous flight I took on my fist leg of the trip. There are no seat TVs, so you must rely on the app when it works. United can do better. Also, what use it it to pay for boarding group 2 when half of the passengers are in the same line as you?
Crew was dismissive. Snacks and refills not offered. Poor business class experience. Bed not comfortable compared to Emirates or BA.
Flight was delayed for 5 hours because crew didn’t have enough time to rest - this seems like it could have been avoided with better scheduling. Food was not good.
IAD with the archaic people movers is just a place to be avoided.
Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks
This is the best united airlines flight that I took. The crew was very friendly and the food was tasty!
It is clear that someone knew, and competent, is in charge of food at United Airlines at least for the international flights. I was flying in coach, but the choices of the dinner were excellent. Tasty, and appropriate size. I had the beef, which was a little bit like a shepherds pie, and it was good. Nothing comparable has been served on a United flight in years. It will not be confused with three star food, but it is very good for airline food. Even better was the breakfast choice between a cinnamon roll and a breakfast sandwich. I chose the breakfast sandwich which was absolutely delicious and which I would happily order again at my local Starbucks or Panera. It is clear that someone knew indifferent is in charge of the food and it’s about time.
Had one staff that was not pleasant. Seems they are stressed with too many people to care for.
When I wanted to check in 3 hours prior to boarding time, the employees mentioned “a little over an hour delay” so I waited for an hour then I went to go look for food in the terminal and most people from that flight were in the same area looking for food. Finally I decided after food to check to see if it’s anytime closer and now it’s 2 mins until boarding closes?! What are you kidding me? I didn’t receive anything via sms about boarding now nor via email or on the intercom. I luckily made it through, barely, and then there’s no room for my carry on mind you I’m in the very first row so I had to place my purse in one further row back and my carry on sections down. Not sure who pays for better seats to get your stuff placed all over the plane but that was the worst experience I’ve ever had flying with anyone.
This airline sucks. They offer low rates then charge you for everything, the app does not work well, the seats are the most uncomfortable. Maintenance issues on the flight, and you still have to sit through their credit card commercials. People are nice enough but does not make up for overall poor experience.
The worst. We never made our connection and they did absolutely nothing to help us at the airport.
Cancelled flight after I arrived at airport after 75 min drive and parking. Next flight was 4 days in the future. Had to scramble and buy a much more expensive flight on another carrier.
I liked the turn-style feature at gate 209B at LAX. Very efficient process. The gate staff also made several, clearly directed announcements so I felt very informed.
The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.
It was a short flight so no food or entertainment….
Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.
Flight was delayed 3 times, would have been nice to have received text message instead of email notifications. Frontier app wasn’t even updated accordingly, no gate number disclosed. No agent at front desk of gate to inform of delay. Very confused and left if the dark
They changed the timing , first delayed by 4 hours then went back to 40 mins late, we had to run back to airport to not miss our flight. This is ridiculous
