If you want a better experience, fly non stop. American has a superior wireless connection experience. Delays appear to be the norm. Book two hours between flights minimum. Check your bags.

An hour before flight was enough time for departing from Santa Rosa. (I doubt anyone is at the airport and working at 4:30am).

It’s pretty simple there. It’s one of the better airports.TSA has never been a problem for me there it moves and is mostly efficient… I was happy that we didn’t have to takeoff our shoes, which surprised me. They’re always seems to be long walk to the gates coming and going not sure why that is

The airplane is a quite small one, compared to the regular size, so pls be ready for some restrictions on carry on bags.

Due to plane delays on both legs of my flight home, I had to be rerouted from Santa Rosa to Las Vegas on Skywest and then to DCA on American. SkyWest airlines sat on runway in Las Vegas for 20 minutes waiting for gate to clear. My boarding pass for American that I was given by Alaska was incomplete and the Las Vegas airport lacked signage and departure boards. I barely made my flight bc it was so confusing. American Airlines has a much better wireless connection. I’ll never fly Alaska again. It clearly has problems.

We left about 30 minutes late due to ramp issues. It did not impact me, but I know others on the flight had very tight connections to Maui.

The crew was very friendly. Boarding was quick and efficient.

No WiFi. Terrible food. Very long walk to the gate and from the gate after landing. Gate changed without notice.

I enjoyed the Starlink access but didn't have much time to use it. It also kept dropping me so I gave up. The food was very good though when I asked for a different "dessert" they didn't have anything. Chocolate Brownie Cookies are not suitable for everyone...maybe children. The flight staff were amazing - at least in First Class! My first time ever! The trip from Boise to San Diego was FAR better than going to Boise.

One of the flight attendants treated my grandma who is 77 years old badly and would respond sarcastically. Example my grandma "do you have and honey by any chance" the flight attendant "does this look like a restaurant to you. She was also very rude to myself and my children giving us attitude and being sarcastic when answering.

we waited for 50 minutes to check a bag and missed a flight. do better.

The flight crew was very professional and pleasant. Our flight was delayed 3 hours, but Kayak informed me in advance

I really hate the seat assignment at the gate. I understand it is so families can sit together but it caused me and others a lot of unnecessary stress and confusion, enough for me to not fly Alaska again. The app is so awful that it did not even update my seat assignment on the boarding pass but sent me a notification of my seat... it showed in Apple Wallet but not in the Alaska app itself. That only made the stress worse. I think most people like myself prefer to know where they are seated at check in 24 hours before so they don't have to anxiously hang out at the gate the entire time. This is not a good use of your agents time either to be dealing with all of us asking where we are sitting. You should automatically assign the multiple seat purchases to be together before they check in and fill us solo travelers in those gaps as we check in.

Alaska Airlines have beautiful new airplanes that have comfortable seats but tight for a tall person like myself. They do provide upgrades to flyers but at a $140 cost. My flight went smooth and prompt as well as without a hitch. The flight crew were warm and friendly as well as very attentive. I'd recommend this airline over Frontier airlines any day.

3 hour delay. Had to change plans and was still delayed.

The flight crew was extremely rude and especially not helpful when our flight was delayed.

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.

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

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.

Delays delays delays. Late taking off, late landing, wait for a gate, etc.

Connecting flight is on time and boarding was a breeze!

Very smooth checking in our luggage with a super pleasant SW agent. I enjoyed a fun entertaining movie.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

Flight arrived 30 min early and bag was waiting at the baggage pickup. United Club HNL was one of the nicest in the system

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Flight was late - I was downgraded from first class to coach

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

7 hours delayed due to operational issues on United’s end. Basically laziness.

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

The flight was delayed by 2 hours and we had no food or water or chargers

Horribly late because they had no crew!!! And then jet bridge didn’t work!! Then we arrived at a gate at lax miles away that we had to take a shuttle to a terminal!! I was over 3 hours late to getting the LA! Should have been here at 8:30 and at an appointment at 10:30 and arrived and left lax at 11 am!! Horrible experience!!!

Once again, the staff seem to think they are above the customers and treat everyone with disdain, belittling people.

Flight was canceled 8 hours before departure for lack of operational control and prepositioning of a plane. Then had the audacity to say it was because of weather, however there was no weather here in California or New Orleans or in between. It was the weather in Florida, Florida it had nothing to do with our flight path just the plane was supposed to fly us. 8 hours is more than enough time to move a plane anywhere in the US. That left me with a bill of 1200 dollars to re book a flight oh and kayaks insurance what a joke. Probably will never use kayak or spirit ever again terrible companies terrible customer service. I’ll also let everyone and anyone know this was an abomination and only for the customer. Also will be making a report to the DOT on bad business practices on behalf of kayak and spirit as well as the BBB. Do better, take care of your customers and don’t suck

The airplane had a strange noise that was constant throughout the flight. Thankfully I had noise-cancelling over-ear headphones that muted much of it.

it was terrible. flight was cancelled hours before the flight without a given reason and no other booking available .

The plane was freezing and everyone had on their winter coats. I pulled out my sweaters out of my carryon to cover myself and put on an extra pair of socks. They offered NO FREE drinks or snacks on a 6 hour flight. The seats don’t have plugs or charges or any form of entertainment- so I just played my one downloaded game on my phone because I couldn’t sleep because I was too cold. Miserable flight though we landed safely.

Always comes in handy when I want a quick weekend getaway.

My luggage didn’t arrive at LAX, so that wasn’t a good experience.

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.

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

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.

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.

i was unable to check in the flight. refund requested

I think Frontier was very good at communication. Their app worked very well. Loading was great and the flight was nice and easy.

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.

Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.

Decent clean onboard experience. Okay discount airline experience. Unfortunately, any customer service interactions are difficult and unhelpful. There is no service. Also, a premium seat only gets you premium boarding if you line up first. Once they start general boarding you must go to the back of the line. Not very premium

The crew was mostly okay. The flight attendant who answered our questions was curt and unhelpful unfortunately. He seemed upset and I understand having off days.

Very bad! No good service delayed my second connection flight
