Flight from San Francisco to San Diego

samantaFlew with Alaska Airlines-Jun 2026

the red eye one is perfect to sleep on plane and get there early morning

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.

JeanieFlew with Alaska Airlines-Jun 2026

Bring your own food and entertainment. The buy-on-board program may require advance ordering, and it can be expensive. Also, the on-board wifi may not work.

Verified travelerFlew with Alaska Airlines-Mar 2026

Airport is very efficient with security, very impressive so. you don't need to worry too much as even a long line moves extremely fast.

CupcakeFlew with Alaska Airlines-Apr 2026

Check flight delays on Google prior to arrival at airport.

JamesFlew with Alaska Airlines-Jan 2026

My advise is to pack lightly to avoid paying for the cost of one bag in the amount of 35 dollars. The amount isn't the worst I've paid, for my traveling bag but so many individuals used the overhead luggage rack as well as a back pack that didn't pay for transporting a large suitcase that I intend to do the same in the future.

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!!!

KathleenFlew with Alaska Airlines-Feb 2026

allow plenty of time to get to the airport and through security. Take the plane train if you can. Terminal eight has good food options

BrianFlew with Alaska Airlines-Jan 2026

I would say bring a backup snack or pre-order food with Alaska. I love Alaska airlines' new food options.

PhilipFlew with Alaska Airlines-Feb 2026

Taking a flight with a smaller plane was pleasant, fewer passengers and.easier boarding and disembarking.

MatthewFlew with Southwest-Jan 2026

If you have Pre-Check don't even worry about getting to the airport early.

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.

Verified travelerFlew with Alaska Airlines-Feb 2026

DCA only has a few flights to other coast. IAD has many. If something goes wrong you’ll have more options flying out of IAD.

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.

HowardFlew with Alaska Airlines-May 2025

Must have a tablet to watch videos. Bring a seat cushion.

Verified travelerFlew with Alaska Airlines-Feb 2025

My flight was not delayed, but my family had a flight earlier in the week that was, by 5 hours. My daughter says she'll never book a late afternoon flight as they seem most likely to be delayed. I personally like the timing and usually they cost less. Also, get on the plan with fully charged devices or a non-electronic form on entertainment.

MichaelFlew with Southwest-Jan 2025

It’s a quick flight and sometimes turbulent leaving the desert. You may not get drinks service due to the brief flight time and safety measures.

Verified travelerFlew with Alaska Airlines-Dec 2024

Get there a couple hours early. TSA is not the best organized. The security line took us about 50 minutes to an hour.

Verified travelerFlew with American Airlines-Dec 2024

Bring a neck pillow and if your over 6 ft tall spend the money for exit row. Other customers are not curteous

OksanaFlew with Alaska Airlines-Feb 2025

Arrive early, the registration kiosks may not work and registration will take more than an hour.

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).

Verified travelerFlew with Alaska Airlines-Sep 2024

Alaska airline has great food but small portions and sometimes isn’t aware of your pre-order, so bring your own just in case!

Verified travelerFlew with Alaska Airlines-Oct 2024

Landing in La Guardia or Newark (New Jersey) is more convenient for commuting to Manhattan.

RebeccaFlew with Alaska Airlines-Sep 2024

Get something to eat in the airport, just in case there is no food onboard.

KeturahFlew with Air Canada-Nov 2024

Bring very small luggage- it’s a small plane.

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

Verified travelerFlew with Alaska Airlines-Jun 2024

The exiting gates and boarding connecting flights are very close, always bring an empty water container that you can fill in the airport filtered water dispensers bring your own favorite food

Verified travelerFlew with Alaska Airlines-Jul 2024

Definitely arrive the 2 hours before your flight or you will have no extra time before boarding. Wear comfortable walking shoes.

CarolFlew with Alaska Airlines-Jul 2024

Bring your own entertainment (book, puzzles, devices). T mobile offers free internet with Alaska!

FelipeFlew with Delta-Jun 2024

Make sure you know where you are going it’s a big airport… if you fly delta you can ride the tram inside to get to your gate if it is far away.

BerniceFlew with Alaska Airlines-Jun 2024

Give yourself plenty of time to get through security.

Joo YoungFlew with Alaska Airlines-Jul 2024

Make sure your seat can recline when you board!

Verified travelerFlew with Alaska Airlines-May 2024

Don't use a small water bottle. Get a big one and fill it prior to boarding so you can keep hydrated better.

JustinFlew with Southwest-May 2024

GET TSA - PRECHECK AND CLEAR. IT'S CHEAPER WITH THE AMEX GREEN OR AMEX PLAT.

LorraineFlew with Alaska Airlines-Mar 2024

Do get there 2 hrs. ahead as security lines can be long.

LisaFlew with Alaska Airlines-May 2024

Be sure your carry on fits in the bins before getting on- big rollers are difficult to get into small Horizon Air bins

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.

Verified travelerFlew with Alaska Airlines-Apr 2024

Austin check in is long, make sure to come early to allow for the crowded lines.

Verified travelerFlew with Alaska Airlines-Mar 2024

Be prepared to wait in long line for shuttle to car rental complex.

FranciscoFlew with Alaska Airlines-May 2024

Make sure to read all the disclaimer disclosures before booking.

MichaelFlew with Alaska Airlines-Mar 2024

Get to the airport extra early for a Hawaii flight.

Verified travelerFlew with Alaska Airlines-Feb 2024

Allow time for TSA (I had) or figure out the priority boarding (I didn't but will look into it for future flights), I thought they were pretty inefficient. A guy behind me was freaking out because he was going to miss his flight and a bunch of us let him cut the line in hopes he could make it.

JosephFlew with Delta-Feb 2024

Your seat selection may be changed at check-in and you may not be able to change your seat to what you originally selected while booking so be aware of this possible issue.
