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

Insights shared by verified travelers who flew the route from California to San Diego 
Verified travelerFlew with Alaska Airlines-Jun 2026
Check your flight the night before! My flight was canceled and rebooked but it is a common thing to have flights cancelled. The airport is small so going through TSA is fairly quick.
CupcakeFlew with Alaska Airlines-Apr 2026
Check flight delays on Google prior to arrival at airport.
PhilipFlew with Alaska Airlines-Feb 2026
Taking a flight with a smaller plane was pleasant, fewer passengers and.easier boarding and disembarking.
Verified travelerFlew with Alaska Airlines-Jan 2026
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.
EricFlew with Alaska Airlines-May 2025
SBP gets busy in the early morning with several flights departing between 6am and 7am. Arriving early will avoid stress.
CaseyFlew with Scandinavian Airlines-May 2025
Better concession options on other terminals than 3, if you’re flying Delta. Explore if you have time.
Verified travelerFlew with Alaska Airlines-Oct 2024
An hour before flight was enough time for departing from Santa Rosa. (I doubt anyone is at the airport and working at 4:30am).
JamesFlew with Alaska Airlines-Jun 2024
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
Joo YoungFlew with Alaska Airlines-Jul 2024
Make sure your seat can recline when you board!
JoonwonFlew with Alaska Airlines-Apr 2024
The airplane is a quite small one, compared to the regular size, so pls be ready for some restrictions on carry on bags.

Airline reviews

Seated at front bulkhead for a smidge extra leg room away from home and on flight back home. Away crew was very proactive about assuring our carryons had space close behind us (because no seat in front of us our personal items had to be in a small bin overhead). They actively required passengers place overhead luggage on its side so more items could fit in bins. Home crew made no such efforts. I had to struggle back rows to get overhead bags upon landing, no crew help then either, and some disgruntled passengers as I and others retrieved our bags. There was a system that worked pretty well. The home bound crew just didn't feel like working.

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.

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

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

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

Our first flight was so delayed that we had 10 mins to board the next one. We requested if the flight attendant could allow us off there plane first and they denied our request even though I have seen this done before. Luck was on our side that we didn’t miss our next flight.

Everything was great except for the in-flight wifi that wasn't working.

Flight was on time. Friendly staff and flight was smooth. We Love Southwest.

I had a great flight from Sacramento to San Diego on 2024-09-20 (at 9:00 am). Everything worked well, the crew was pleasant and efficient. Thank you!

Was very easy to board but when you get to the confirmation board it was too high for me to see even with my glasses so I just hoped that I was lead to the right gate and waited for boarding.

A refund because I never got on any you guys never canceled it in the first place

The problem was going through San Diego, a trip that's become a new development.

Flight was canceled in good weather due to mechanical issue. Rebooked to flight to different airport in area that landed 7 hours after initially planned arrival. We had to jump through hoops to get taxi reimbursement given flight landed in different airport at 12:45 am.

They cancelled the 6am flight around 12:30 AM the day before. I was luckily able to book through another airline. I called for a one way fare refund, the new flight is much more expensive. I lost $$$ in the difference and this caused lots of stress. I intend to take action following my trip, really off to a bad start and I will never fly Alaskan again

My travel mate needed wheel chair assistance getting on and off, and it was excellent. Thank you!

Over all it was great. My original flight was canceled but they quickly rebooked me. I was frustrated because I had to cancel my entire plans for the day but all considered, not bad. The crew tried to keep us calm while we sat in the plane for was felt was an hour or so but they could use a bit of a script. The seats were comfortable and I would give it another try.

Not able to get boarding pass for domestic connection flight when check in at international airport. I was told I need to get connection flight boarding pass after I entered US. It us very inconvenient.

The gate agents begged us to check our carryons. They BEGGED us, over and over, and said that the flight was completely, totally full, and said that if we don't check our bags, it will cause huge delays. They finally said that "group suchandsuch will be required to check bags!" So I checked mine. Well, the flight wasn't close to being full, and many of the overhead compartments were *empty*! Moreover, my bag was delayed at the carousel, and it wasn't on the carousel that was posted. COME ON, AIRLINE, you can look at the seating for the flight on your computer and decide whether it's really necessary to beg and beg and beg people to go through the hassle of checking their bags! This is annoying as hell and makes me not want to use your crummy airline ever again.

It is a hassle to not have entertainment screens on the backs of the seats.

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.

UA594 was delayed multiple times. I ended up getting picked up so I can make it in time for work 6AM on Monday, 7/6/2026

Service was professional and quick. Premium economy seat was comfortable given the class

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

Was a pain having to leave the plane and reboard but glad the plane was fixed

Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.

For a 22 minute flight all you expect is for it to be safe and comfortable

Lost connnection had to stayON in Chicago Was a mess

Booked economy through United - air canada treated it as standby and was almost refused boarding.

Awful! We boarded and then sat on the plane for 50 mins before having to deplane due to a maintenance issue which should have been addressed before boarding. Then we had to change terminals as there was no other plane for us at the current terminal. Then we waited another 2 and a half hours to board again only to wait for 50 mins on the plane again for the snacks to be brought from the broken plane. And once we were on the flight we still only got the complimentary cookie and soda or water. No food vouchers provided even though we had waited over 3 hours for our flight.

Delayed for mechanical and no updates on what was happening and how long the delay might be.

We are too tired and frustrated to comment politely at this point

My flight was delayed for several hours. Sitting at gate 16 for several hours, I got a text from Kayak the gate changed to 9 before it was announced. Very bad communication at each gate from American Airlines employees. I received 10 notifications of delay from Kayak. My vacation started off horrible! I will write to American Airlines corporate office also.

The service and food needs to improve to catch up with other international flights

The flight crew was fantastic! Which the seats had a small TV.

also wi-fi never worked attendant said satellite coverage is spotty over water ..... but we were over land!

They attended to my needs as I couldn't walk and they provided a wheelchair for me.q

This time my flight was smooth and uneventful. They started boarding even earlier than it was scheduled. I was pleasantly surprised. Thank you!

Boarding was a mess - the agent basically called every group in rapid succession, so there was no organization at all. The economy seats are a joke, and main cabin extra seats were sold out when I purchased my flight. As such, I was locked in the same position for four hours. Being 6’6”, it was impossible to get my bag out from under the seat in front of me, and I couldn’t have used my laptop even if my bag were accessible due to the minuscule seat pitch. Also the wifi was broken. American is a joke - can’t wait until they merge with Spirit.

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

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

I went to the Frontier counter in San Jose at 1030am or so on Sunday 10/13/24 to see if I could get an earlier flight to San Diego in lieu of my reserved 630pm flight. One thing led to another, and I was able to obtain an open seat for about $ 56. on the earlier flight. Fine. Then the agent asked if I "was checking a bag". Not knowing that carry-ons cost extra per Frontier policy, I thought that she meant a regular checked bag. Therefore, I said no. Once I got to the gate, the same gate agent who sold me a ticket told me that I had to pay $99 for a carry-on, and that all bags were extra on Frontier. Having never flown on Frontier, I was not aware of this. Part of the issue was that she was not a native English speaker, so there was a miscommunication as to what "bag" meant. I would have preferred for her to have clearly let me know at the front counter that any bag including a carry-on cost $99. It would have had the same outcome, as I had to take my carry-on. But it got hectic at the last minute at the gate itself. The baggage policy should have mentioned "including carry-ons" when we first spoke.

Literally everything could have been better. Why are the planes always late?

9hrs delay and didn’t provided anything until after flight landed $75 voucher for fiuture travel no meals or anything.

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it

The boarding time. I was in Section 1 the lady in charge just let people in section 3 without see us. Make a line , I have to step out and ask her. We were in the line and she just take my ticket and that’s it, so if I don’t ask her she could leave us at the end! We paid more for that privilege and. She doesn’t care….
