Flight crew and flight were good. But it departed two hours late.

No beverages were served on the flight to Vegas as there was turbulence. It was actually one the smoothest flights that I have ever been on. My return flight home I upgraded my seat for $87 and the crew came through the cabin and served every row except mine drinks... I was waiting for them to come back and they never did. I most likely would never fly Alaska again. It was my first time and I've had better service on Frontier... Might as well pay less for my flight and still get to purchase something to drink than pay more and get passed over.

Pretzels are always a disappointment. Cheezits, Sun Chips, trail mix, anything else would be nice.

They cancelled like the flight at midnight, seven hours before the departure. Terrible.

Complete flight rebooked and 6 hours delayed. Zero accountability from the airline or Kayak for the issues and I’m injured which is why I opted to pay more to fly than drive because it’s painful to sit or stand too long. What was supposed to be a 3ish hour travel day turned into a 9 hour excruciatingly painful experience that has left me in worse pain than when I initially started.

We were delayed for hours and this was very difficult, which is why the experience was less pleasant

They were friendly, efficient and got our bags to us so fast at the end of the flight.

The most comfortable plane ride I’ve had in quite a while.

always delayed. toilet is too stinky worse than smells in sf homeless distriction

Get more efficient check in staff. My boarding pass was printed with different name. My son who was traveling with me had his boarding pass printed in duplicate and we were interrogated like it was our fault that I may have lost my own boarding pass when the staff knew very well she just handled and tore the piece she need. This was with PAL.

They sent a notice that they were boarding an hour early. We had to leave the club and run to the gate. They said sorry, that came from corporate and was a mistake. They did not have enough seating because the flight before it had not taken off on time. They moved our gate and delayed it for an hour.

The boarding and seat assignment system no longer works for me, but I know it is being replaced. Otherwise, I am good with the overall experience.

The lead steward kept singing about "San Francisco" and hotel California---more annoying than humorous....needs work. Flight was smooth and on time.

Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.

Airline travel is always too cramped to really be pleasant, but the cabin crew on this flight did a pretty good job of making up for it by putting on some music during boarding and sprinkling a few funny remarks into the safety briefing and announcements, and just generally being friendly and helpful. It definitely reminded me of why I prefer the in-flight experience on Southwest!

No delays and arrived to destination 30 min early. Staff was super friendly.

San Diego airport is brand new, spacious, airy and very smooth checkin at SW baggage drop.

It was rough. The staff was unprofessional, the choice of on board drinks terrible, it was cramped in space at every airport, they always ran out of overhead bin space so they pressured people to check bags for free or we couldn’t leave on the plane— so I did check my bag to help, and they nearly lost my bag. My bag did not arrive on the luggage belt, another man on my flight and I had to waste our time going to the baggage office to search for our bags. I would only fly southwest again if it was my last choice. Also, my flights were consistently delayed over and over again— at one point they straight up told us we were waiting for the pilot to arrive.

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

Had to get off plane from prior flight even though I had to reboard same plane to continue to my final destination.

Flight scheduled to take off at 5.55pm but it did not take off until 7pm due to some food delivery delay.

Unfortunately, I was put into the middle seat in the first row of premium seating. Sounds nice right? No! that is the worst seat in the plane. I wish I was in economy rather than be in that seat! There is no seat back pocket, no tray table, no charger. Nothing! so unless you're row mates are willing to let you share their basic amenities any flyer should have, you are stuck. It was the worst experience ever! And the flight attendant forgot to take my drink order. I felt like the forgotten flyer.

Delayed and cancelled flights were hard and very stressful, both ways!

The crew was quite good, they came by often with drinks or to collect trash. But what wasn't nice was the flight was over weigh and several people had to be rebooked. I was questioned whether I should have a seat when I was getting to it. The in-flight entertainment kept buffering and interrupting. And the route took the airplane through high winds which caused us a longer flight

Wasn’t on the flight due to Alaska cancellation…also after all the rerouting, I was going to be on a later flight that left SFO at 7:47pm, which meant an almost 6 hour layover. That same Hawaiian flight was delayed for another 2hours.

I had to cancel the flight because with a 3 hour delay for 'unexpected maintenance' in getting to LAX, I couldn't connect to an overseas flight that I had booked on Scandinavian Air.

The flight was CANCELED!!! Can’t get much more “poor” than that. I had to switch to American Airlines, add another layover and got home in Honolulu 4 hours later than I was supposed to be home. One bright spot was Josh with Alaska Airlines at SFO. He got me on a United Flight that got me home a few hours before I would have. Without him I would have gotten home almost 7 hours after my originally scheduled flight.

Canceled my flight within 24 hours, causing me arriving home midnight. Will never book Hawaiian airlines anymore

I like Hawaiian, it was great that they had good internet connection across the Pacific Ocean, thanks to Star Link satellites. The seating was comfortable, ( I was in economy ). Maybe I missed it, but I only got offered a beverage once. It was a nonstop flight KOA to SMF. I would take it again next time I go that way.

I always love flying Hawaii and I have nothing to add

Clean, friendly, roomy. But check-in from the phone link was terrible. Repeated attempts wouldn’t save at the final step. Just kept spinning! It was very frustrating. Finally, I used the app (vs website link) to check-in which worked very smoothly on the first attempt.

Check in on the web portal was cumbersome! After several attempts I finally got the boarding pass.

Excellent flight and even arrived 23 min early. No entertainment , or wi fi on board, but I downloaded a couple of movies beforehand which kept me entertained. Really like flying Allegiant airlines.

WE were delayed about an hour and never any communications from the employees working the gate. We also were moved to a total of three gates.

I love how they show love to their customers and care about them too.

I liked how when I got on board how fast we ended up taking off but what I truly disliked was how uncomfortable the seats were. There was truly never a time that I could ever get comfortable during both of my flights. The seats could get away during shorter flights but flights 3 hour plus makes it hard to enjoy.

The crew was great and the flight was very smooth. Can’t really judge food since I did not get any because it costs money. The seat was comfortable for what we bought. Thanks!

Crew was great. No entertainment and food and beverage was for purchase only, even water

It was canceled. The flight wasn’t rescheduled, everyone had to figure out their own new arrangements. They said we would get refunded our original fare and receive an additional $150. We received links for $100 only and they expired before we could activate them.

The plane had originated in Las Vegas at 6:30 in the morning and flew to Moline where we boarded. The flight left around 12:30 PM and there were no boxed snacks available and many of the alcoholic beverages were unavailable. I would find it hard to believe that that many of the passengers coming from Las Vegas at 6:30 in the morning, drank and ate that much of the items. I can only come to the conclusion that someone failed to stock the plane for the round-trip. This is a huge revenue failure for the airline and disappointment for the passengers. The flight crew did not seem happy to be there and did not engage with passengers. Allegiant you can do better.

Absolutely horrible. Usually pay $40-$50 to check luggage in. I tried to check my suitcase in and the price is raised to $70. That's ridiculously greedy c'mon. I had to leave my suitcase with all my clothes and hygiene products and repurchase once i landed in Atlanta. You guys make it really stressful to travel. Don't even want to travel anymore.

I was never aware that I had to pay $100 per luggage to them on the plane that are simply carry-ons. This is discriminatory and I’m going to be alerting my entire family and friends and my Instagram following up over 75,000 of this issue and misunderstanding, including mismanaging.

Delayed due to no pilot. Per FAA policy I do believe we are to be reimbursed.

The flight was flat out cancelled. Spirit no longer goes to Seattle. I had to rebook my flight. Get a refund from spirit. They also didn’t send me any notification of the cancelled flight.

Spirit rescheduled a 4:30 PM flight to 8:52 AM. That's ridiculous and borderline fraud.

The terminal crew is so rude cabin crew is extremely rude flight is very good

Flight was late, after my first leg was cancelled altogether causing me to spend $$$ with another carrier. Seating is ridiculously tight, I can't recommend spirit if I cant depend on them to get me there and back on time.

Late departure by 1:45min. No explanation why. During boarding inconsistent policing of their baggage rules. Before takeoff and lamdimg strange obsession with window shade and armrest positions. Don't know why they care. 15 min tarmac delay on arrival, they blamed airport congestion but we were the o lh flight waiting, it was clear it was due to poor staff planning (only one ground crew to receive airplanes and multiple arrivals) Got there but was rrally lame the whole trip.

One of worst experienc my family have every had with this airline. I was informed my Kayak that my flight was delayed and that my family will not make it to houston for our connecting flight. I contacted Spirit customer service to get my family on a later flight due to the delay in Vagas and them not making their connecting flight. The customer rep keep telling me that the flight from vagas is on time and not delayed. She even make to go to the spirit app on my phone and show me how to look up weather or not the flight was delayed. The app showed "on time" 20 minutes later when my family arrived at the airport for their flight, they were told that the flight was delayed and she will not make her connecting flight. I call spirit airline customer support again that night and spoke to another rep who apologize for his collegue and he told me that my family will receive a credit for this, this was on Saturday I still have not received the credit or an email letting me know when I will be credited for this inconvenience. This is not good business and it need to be fixed.

Flight was cancelled. No reason given. No apologies. Next available flight is two days later. Ruined our 4th of July plans.
