Flights from California to San Francisco: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from California to San Francisco 
JakeFlew with United AirlinesBIH-SFOJul 2025
Security in Bishop does not open until 1 hour before the flight.
RonaldFlew with Alaska AirlinesSNA-SFOApr 2025
The airport security can take a long time, the bathrooms are not always available near the gates due to construction, repairs, remodels.
Verified travelerFlew with Alaska AirlinesLAX-SFOJan 2025
Bring water and snacks with shorter flights as some routes will not offer it.
CongFlew with United AirlinesSNA-SFONov 2024
Nothing really, being clothes that are easily taken off like shoes at the security will always save time
VyomaFlew with Alaska AirlinesSAN-SFOJun 2024
Be sure to read the signs, i have heard it's confusing for connecting flights if you don't follow the directions.
Verified travelerFlew with Alaska AirlinesLAX-SFOJul 2024
Bring a sweater, just incase other people's ac makes you cool.
Verified travelerFlew with Alaska AirlinesSNA-SFOFeb 2024
Long Beach and SNA are convenient airports for flying out of Orange County. I wish I knew about the size of the plane which caused a fee for checking one small bag that normally was a carry on for other airlines such as SouthWest.

As always to close confinement for passengers not in upgrades. I like that you still get carry on and personal bag.

As always to close confinement for passengers not in upgrades. I like that you still get carry on and personal bag.

I had a negative experience, the flight delay was very long, I didn't like it

The seats in first class are very dated and quite uncomfortable. I don’t need lie-flat seats for a 6 hour flight, but more recline is really necessary.

One of the stewardess, Tre, went above and beyond to ensure my comfort!

Passengers were not informed timely of delays. The staff appeared like they didn't really care about the passengers.

Flight was delayed for weather, then delayed for mechanical, then just cancelled. Once mechanical problems started I wish you had just started offering rebooking options (at the same airport). I felt my trip was not a priority for you. I called you, I asked for a better option (than changing airports), then I had to literally run around the airport making it happen. Do better.

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

It was too cold for the first quarter of the flight.

Check in, they should have told me that upon arrival i needed to exit the secure area and re-check in with Eva Air. I wasn't sure what to do upon arrival at S.F.

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.

First time traveling on Southwest since bag fees were implemented. Usual good service. Just more expensive now.

It was a perfect flight in all aspects! Both legs!

Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

I will be flying again Southwest Airlines. Friendly crew, comfortable and affordable.

The plane arrived 25 minutes late, and the Wi-Fi was slower than it usually is.

Food was surprisingly good but the WiFi was not great

My husband upgraded our seats and I don't know if it was due to the type of planet was or if they didn't upgrade our seats. We were supposed to be in I believe comfort seats and they were just as tight as any other seat- no leg room and we are very tall people but at least it wasn't extremely cold. My husband did put in a complaint about our seating because he paid extra and if we would have known that the space and the tightness would have been the same, we just would have gotten the emergency row emergency row seats that we normally get. We love Delta but both our flights coming home we're not good. Oh I forgot to mention that on our flight to Hawaii our luggage wheels got broke and we had to purse new luggage on vacation then we never had this problem so we didn't know protocol and reported it after we got home only for them to tell is we only had 24hrs to report the damage. Not sure what was going on with Delta this vacation trip.

My flight was extremely cold. I had a jacket and a cover was left in each seat. The cover was extremely thin and I have a disability, fibromyalgia and arthrithis and AC air is the worst. I closed my vent and my husbands vent and it still was frigid. I asked the attendant if I could get another cover and she quickly almost dismissively and totally unconcerned stating, (I quote) (one per chair) and walked off so quickly that I didn't get a chance to explain to her that I literally have adisability. I didnt want to make a seen so I set on that flight for over 5 hours in pain, joints locking up and extremely uncomfortable. When my fibromyalgia flares up my joints not only ache but they will lock up also and it takes me days to get back to my regular self even though I take medication for it. I felt like it would not have hurt anyone at all for her to just give me an extra cover because I'm sure they have all types of medical issues in people that fly every day.

Crew was excellent. Comfort seats not as nice as other kinds of planes.

Not a "Delta" issue, but a JFK issue: We booked a connecting flight with 3 1/2 hours between to clearn immigration and customs. Our inbound flight (BCN to JFK) was on the taxiway 45 minutes which ate into our layover time. Immigtration was insanely quick with the CBP MPC app; however, clearing TSA (again, after we were ALREADY cleared in Spain on the inbound international flight) took over 95 minutes. This left us with 10 minutes before boarding the connecting flight (JFK to SAN) to walk to the far end of Terminal 4 and try to find food. We didn't find any food that could promise to serve us in under 10 minutes so we boarded the Delta flight after coming off a plance and an 8-hour flight knowing that we wouldn't be served any food on the next 5 1/2 hour flight. I feel like Delta needs to put pressure on the JFK TSA to open more screening stations (by our count, we saw only 5 scanners open and a line of - as we said - over 90 minutes. The insult is that we WERE ALREADY SCREENED through TSA, but as you come off one flight into the USA, you have to go through the whole process again. It seems like if you have a connecting flight, there should be a way to pass through immigration and customs without needing to return through TSA.

It was a great flight and the stewards and stewardess were all kind and accommodating!! The seats were comfortable and entertainment screen excellent!

There are 4 flights in consecutive gates with about the same departure time. Two flights were boarding at the same time. One was delayed or boarding would be happening at the same time. I am not sure what Delta and LAX need to do to have a better layout at the end of Terminal 2

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

The entertainment and wifi mostly didn't work on this flight.

Terrible entertainment system - kept freezing and audio kept cutting out. Snacks were mediocre at best for a 5 hour flight.

Boarded plane and then delayed 1.5 hours while on the plane

My flight was delayed a very short period of time but they did not hold my connecting flight to San Diego, also through United. So they closed the doors before we got off our plane. They would only have to help the door open for another five to ten minutes. So I missed a court deadline for a manditory mediation settlement conference for my client. I had to get an associate to be there in person and be on the phone with him relaying what he needs to do the entire time. The court was very upset with me and so was my client. United cannot be trusted.

Really good 😊 the woman at the gate entrance was a little rude checking in our carry-on but i dont think she worked for the airline, she worked for the airport at sacramento, other than that amazing.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.

United out of SFO is having issues with catering so none of our meals were loaded on the plane and no offer of compensation for our tickets purchased was offered.

A bit rush for transit. Food and entertainment are not available

The gate was too far away for the connecting flight

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

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

They canceled flight. Hard to believe there was even a plane incoming for us to get on

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.

Plane was down graded and I lost my uncharged exit row with more leg room. No mention or offer of refund from podium. Flight attendant was nice to explain this happens often and that I could request a refund via online form submission. I did this and have heard nothing back.

Horrendous. I do not recommend Frontier. The passengers lack manners and decency, and the flight attendants lack professionalism. If I wasn’t in a bind to fly with 48 hours notice for a job interview, I would not have selected a flight with Frontier and I never plan to fly with them in the future.

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

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….
