Flights from Boise to California: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Boise to California 
Verified travelerFlew with Alaska Airlines-Jan 2026
Since I flew First Class I really have no advice! Everything was perfect! The ticketing agents were fantastic, flew through TSA Precheck, great announcements at the gate, quick boarding. My only suggestion is to check First Class prices before committing to the very expensive baggage fees and choosing a seat fee!!!
Verified travelerFlew with Alaska Airlines-Feb 2026
Dont wear all your clothes its not worth the discomfort to save on a checked bag.
LisaFlew with Alaska Airlines-Jul 2024
If they ask you to check your bag at the gate because the flight is full, you get to board sooner even if you don't check ALL of your bags.

I fell asleep and missed my flight and they rescheduled me no problem. Staff was professional and the plane was clean. I was very happy with my experience.

I fell asleep and missed my flight and they rescheduled me no problem. Staff was professional and the plane was clean. I was very happy with my experience.

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.

Our late returning flight was annoying. The plane was small, but it made boarding and disembarking quicker. I do wish they offered a gluten free snack.

I was standing in line to use the restroom. A First Class passenger wanted to use the restroom after me, but Jaques made me wait on Flight 3418 from BOI to SJC on December 12, 2025. I felt this was inappropriate and rude.

Excellent, I traveled with my adult mom, she was happy for your service, especially, because you helped her with the reel chair. Only a little thing, in the airplane to Boise, the seat was very worn.

Everything was great, your crew is always very pleasant. Your airplanes are always so cold though.

It was a little chilly on the ride. The entertainment was the book I brought, and it was excellent.

Great service. My wheelchair was ready and waiting for me

The check in bag fee should have been disclosed when I booked my flight.

The absolute coldest flight I’ve ever been on, even with a sweater and zip up sweatshirt. Was miserable the entire flight.

It’s too cold like fridge and they don’t offer a blanket with expensive price

A List preferred boarding was nice Asked for a mask and cheerfully received Denver bag check-in is tricky. Not near other checking desk. Have to navigate to east security and up to level six for bag checkin. TSA busy and 20 minutes process thru pre lines Denver train to gates quick but one more thing to plan time for and long concourse walk to gate

Not exactly Southwest’s problem, but the new Burbank airport is not great. No restaurants open and tons of work still to be completed. Can’t believe they opened the airport in that condition.

Southwest has lost most of what made it special. The flight attendants all used to seem fun and like they were having fun. Now they seem just miserable. They do NOT seem happy to give you your pretzels and drinks. They stick it in your hand or on your tray like it's an annoyance. They bark safety instructions at you. It's not just this flight but the last few SW flights I've had to SNA and SAN as well and it's not just me. I've informally surveyed my colleagues (business and leisure travelers) and these feelings are consistent. The tickets are similarly priced to other carriers and the seat assignments make boarding slower. The free luggage and free ability to change flights is still a differentiator. You lose that and there's virtually nothing special left.

Overall good experience...exception: very cold temp in teh cabin.

I liked how it boarded fast. I do not like how the seats are just too narrow, and I’m not a big person.

Despite paying for an ‘upgraded’ seat in row 1, I had to put my luggage in the middle of the plane. Snacks were bleh and seat was small and uncomfortable and I am not large. Attendants were fine but not super helpful. Plane just seemed outdated.

Delayed for no reason at all originally. Then they said it was due to weather conditions. Communication between kayak and Southwest was terrible because both displayed different delays and departure times for HOURS throughout the day. The plane then had technical issues which delayed us from taking off even longer. Didn’t actually take off until 11:45pm when the original departure time was 7:35pm. I didn’t get home until 1:30am the next day. I was exhausted and pissed off. I am not confident if I’ll fly southwest in the future or use kayak to book.

Flight was fine. Only thing was flight was delayed nearly 2 hours. Flight was originally scheduled to depart at 7:50pm but didn't depart until 9:50pm. I got home around midnight. It was later than desired and I had to get up early next day to take kids to practice. I have noticed that last flight of day on West Coast for Southwest always tend to have delays.

The WiFi and crew on the plane were good, however, the boarding experience was awful. I paid for the Choice Preferred and was boarded in group 5 so all overhead storage was full. They found room for our luggage, but further back making getting off the plane a nightmare. Also, we were in row 6 and the seats were extremely uncomfortable. Both my daughter and I had no leg room and couldn’t wait to get off the plane.

dropped my bags at Seattle Delta curbside. 1.5 hours before departure. one bag oversized made it. the other was left at curb and mishandled. poor communication from delta in sjc baggage claim. No internet on flight and food choices in business are horrible. You are forcing us to fly Alaska which is shockingly better than the Delta experience. that is a low bar.

attendents were rude and the boarding was disjointed and poor

There was an incredibly surly flight attendant that ruined the experience

After boarding the plane had to wait an hour at the for the copilot to show up before we could depart

The cabin and bathroom experience was poor as the cabin and bathroom were dirty and showed signs of an older plane that had not been updated for Customer’s, comfort and health. There was gum on my seat when I arrived and dirt spots around the fan and light controls. The flight was almost entirely full, so there was no way I could be moved from my seat. Th bathroom had the peeling paint.

Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.

I'm 6' 2" and even in economy plenty of leg room

great! appreciated the last minute upgrade to Comfort+ exit row, as well

My seat was changed without my consent. It wasn’t a major deal but annoying.

I specifically picked out right side aisle seats because my left knee sometimes needs to be stretched. But my experience this trip was that the seats were shuffled and I lost those assigned seats, resulting in me having to sit in a much less desirable position for my comfort.

I purchased a Polaris ticket. The plane did not have the lie flat seats - I was not notified. I actually can not believe they traded a dif plane and did not notify me or refund monies

⭐ Absolutely AWFUL Experience with United Airlines! If I could give United Airlines ZERO stars, I would. The seats have practically NO legroom, making the flight feel like being crammed into a tin can with nowhere to move. Comfort? Forget about it! And the fees? Absolutely ridiculous! They seem to charge you for EVERYTHING. You pay for your ticket, then get hit with extra charges for things that should be part of a decent flying experience. What’s next, charging passengers for breathing? Flying with United feels less like being a valued customer and more like being a walking wallet. The seats are uncomfortable, the legroom is pathetic, and the constant nickel-and-diming is infuriating. For the price you pay, you would think they could at least provide a little space to stretch your legs and a travel experience that doesn’t leave you feeling ripped off. Do yourself a favor and look at other airlines before booking with United. I certainly won’t be rushing to fly with them again. Absolutely disappointing from start to finish!

My flight from Boston to SFO was fine. Crew was friendly and helpful. Food was mediocre. Fright from SFO to MNL was not as good. My flight attendant was friendly but didn’t seem to have a lot of experience. She seemed overwhelmed. Also, this was the only red eye business class flight I’ve flown which only served dinner 2 hours after takeoff in a 13 hr flight. When I woke up 1 hr before landing, everyone was eating so I assumed bkft was being served. I pushed my button for help and no one came so I approached my flight attendant and she said they don’t serve bkft but she gave me choices for lunch or dinner. I routinely fly business class but I was disappointed with the lack of service and attention I was given on this flight. Also, most airlines will offer a snack or coffee before bkft is served but this was not offered during this flight. Overall, it was disappointing.

It's not United, but TSA security at Terminal A in Newark is a disaster and seriously makes me consider switching to flying out of JFK. The touchless TSA pre-check had a line of over 50 people and the bag screening was so slow that it limited the flow of people through the facial recognition process. It is the only airport that I frequent that has this issue and makes me reconsider whether I should fly out of Newark given the wasted time and frustration it causes. As I said, it is not a United issue but will impact United if people choose to stop utilizing Newark airport because of the poor experience.

The food could be much better. Also very unfortunate that most of business class seats were empty but I could not upgrade.

Bag got checked but I thought one personal item was guaranteed.

The seats are very small, that is all the staff did a good job.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

During landing. 2 crew members passed 3 times by my lane and didn't notice that people in front of us had their site to the furthermore reclined... That was uncomfortable and could have been dangerous.

United Airlines was fantastic, however, UnderPricer was a nightmare. I got to the airport 4 hours before my flight. We are moving to New Zealand so had quite a bit of baggage (16 checked items) and so wanted to have plenty of time to get everything taken care of properly. When I went to check in they (United) could only find a ticket for me. The 5 tickets for my children were never officially ticketed. I called Underpricer and they told me it was United's fault and United told me that Underpricer just needs to reissue the tickets, but they refused to. I asked the Underpricer agent to transfer me to his supervisor as I was not getting the help I needed. He told me the supervisor was busy but that he would call me back in 30 minutes. 30 minutes came and went with no phone call. After an hour I called Underpricer back but they would not let me talk to the person I had talked to before, just told me that he was talking with the supervisor and technical support. I called again an hour later, was told the same thing. I tried again later, with only about 30 minutes until my flight was scheduled to leave (meaning I had been at the airport for more than 3 hours with my 5 children trying to get ticketed and board the flight). Also, my husband had moved to New Zealand 3 months prior, I haven't seen him in 3 months, my children hadn't seen their dad in 3 months, we were all extremely eager to get on that flight and get to New Zealand. The situation with the tickets did not get resolved until after it was too late to check our luggage and board our flight. We were devastated. My 11 year old son was in tears at not being able to be on his way to see his dad. Thankfully we were rebooked for the next evening, but that night it felt devastating. We'd been at the airport for 4 hours waiting. My in-laws waited with me and then helped me reload all our baggage and took us home to stay with them for the night. On the newly booked flights we could not sit together - my children were spread throughout the plane. So, even though I had paid extra to select our seats after buying my seats from Underpricer only two of us were able to sit together (thankful that my 11 year old wasn't all by himself, but not happy that my 14 & 16 year old daughters were seated by strangers). I really feel that Underpricer should refund me what I paid for the seating ($120 USD). It was a very frustrating situation and I plan on never using Kayak or Underpricer ever again.

Terrible. We needed to change return flights due to an incoming hurricane. They would not refund our return flight.

The employees at Sioux Falls airport were friendly and helpful. As a veteran/retired military Allegiant allows two checked bags, one carry on bag and a seat on the plane all at no cost. The flight crew and pilots were friendly and very competent.

The check-in and flight crew employees are excellent. The flight was good and the seats were adequate.

The flights to and from Cincinnati were great at being on time for both, departures and arrivals. The planes could use some updating.

It was a dismal experience. The flight was delayed for 4 hours, and we spent hours in the plane, without air, during the summer. We were not provided with water, and the medical assistance was inadequate when it arose.

The landing the pilot was very smooth. The flight attendant was kind of rude.The boarding the plane in punta Gorda was not great made us wait out in the heat 😞

My exit seat was very comfortable Coffee was to be purchased but sodas free 😏

The flight was very delayed (in BOTH directions - outbound and returning). The flight was very very cramped. The plane taxi'd on the runway for a really long time, and I got claustrophobic being in such a tight seat. The pilot and crew both indicated that we were going to make up lost time due to the delay, but the plane arrived LATER than expected.

A foot rest for short legged people and a complimentary water would be nice.

The employees at the check-in counter said my disabled wife and I were going to be separated even though we picked seating together when we bought our tickets. They told us my wife would be seated in row 2 and I would be in row 8, because we bought our tickets from a third party. Fortunately the flight crew said: "No, you two need to be together, we'll fix this." Then they seated us together. We are 75 years old and flying is a challenge for us, so we appreciate all the help we can get. Your flight crew was awesome with us, and with the children on our flight as well. Thank You Allegent Air Lines! 🙂
