Flights from North America to San Francisco: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from North America to San Francisco 
GeraldFlew with DeltaBOS-SFOMar 2025
Book a flight early in the morning. The plane & crew will have arrived the previous night
SanketFlew with Flair AirlinesYVR-SFOMay 2025
Arrive 1:30 hours early if you don’t have a boarding pass. They won’t issue it if you arrive within 60 minutes of departure.
Verified travelerFlew with Alaska AirlinesPDX-SFOMay 2025
My mom told me prior to boarding an airplane I should empty my bladder. As I age, that advice becomes more sage.
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.
RobertFlew with Alaska AirlinesPDX-SFOMay 2025
That flights from Portland to S.F. with an international Eva air connect require checking in again before boarding
LuisFlew with DeltaJFK-SFOMar 2025
It’s a long flight, come prepared to either watch movies, read or sleep.
Verified travelerFlew with United AirlinesYVR-SFOMay 2025
Prepare for long lines at car rental offices
RobertFlew with United AirlinesSEA-SFOMar 2025
If you’re picking up a rental car it’s not very clear that you have to take the train. Signage can be improved at SFO.
HartajFlew with United AirlinesRDU-SFODec 2024
RDU long-term parking can add 30-70 mins to your departure time. At terminal 2 in RDU, getting a taxi can take 2-5 mins, vs. waiting 10-30 mins for a car app pickup. :)
GeraldFlew with Hawaiian AirlinesHNL-SFOFeb 2025
There is an agricultural inspection of carryon bags at the gate. Don’t try and bring home any pineapples.
Verified travelerFlew with Alaska AirlinesLAX-SFOJan 2025
Bring water and snacks with shorter flights as some routes will not offer it.
Verified travelerFlew with Alaska AirlinesDCA-SFOJan 2025
Reserve your plane seat & bring something to eat in the plane.
Verified travelerFlew with Alaska AirlinesMCO-SFONov 2024
Use their app, it’s great & they notify boarding, etc
JoanFlew with Porter AirlinesYYZ-SFONov 2024
Maybe get the choice above the cheapest option because you don't get a checked bag or carry on so in the end you end up paying about the same, if not more.
CongFlew with United AirlinesSNA-SFONov 2024
Nothing really, being clothes that are easily taken off like shoes at the security will always save time
JulieFlew with Alaska AirlinesJFK-SFOOct 2024
Leave early. JFK can be messy. I couldn’t find healthy food choices so eat before you arrive.
CandaceFlew with WestJetYVR-SFOJul 2024
I would recommend Westjet. I suggest checking in at the agent counter. My husband & I don't mind sitting apart on a short flight rather than paying to sit together, but the agent was able to get us seats together. I did think the prices for selected seats was reasonable. Baggage fees were confusing & a bit pricy, but carry-ons were free & plane had large overhead bins.
PaulaFlew with Alaska AirlinesBOS-SFOJul 2024
Get your boarding pass online and save it to your wallet App on the iPhone. Makes it so easy
SoniaFlew with American AirlinesDFW-SFOAug 2024
Leave at least 1.5 hours between flights as Dallas is HUGE!
Verified travelerFlew with Alaska AirlinesJFK-SFOJun 2024
SFO is one of the most convenient and pleasant airports. When flying Alaska Air make sure to bring your food and a larger water bottle that usual (you get only two drink services (one small cup each) for a 6 hour flight.
HibaFlew with Porter AirlinesYUL-SFOAug 2024
People with kids or disabilities should be informed that boarding this flight requires taking stairs and a bus. Also, although this was over 5 hr flight, we were only served tiny snack bag and a drink. WiFi was great👍.
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.
NoamFlew with Alaska AirlinesIAD-SFOAug 2024
Flying to the Ronald Reagan airport is closer and faster to D.C. than the Dulles airport.

Bring a sweater, just incase other people's ac makes you cool.
Verified travelerFlew with Alaska AirlinesJFK-SFOMay 2024
The airport food was limited and expensive. Best to bring a sandwich from outside…
ShengFlew with United AirlinesFLL-SFOMay 2024
Arrive early for morning flight. Airport had really long lines!
DeniseFlew with Alaska AirlinesIAD-SFOMay 2024
Bring your own device. No screens on the seatbacks.
BrianFlew with United AirlinesYVR-SFOFeb 2024
If you don't have Nexus, etc., you can pre-book your Security appointment. Much better than waiting in line!
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.
LarryFlew with DeltaATL-SFODec 2023
Get there early. The TSA security line is very long.

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

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.

Laney was very helpful. I am computer illiterate. She helped me obtain a boarding pass and preferred seat. She was warm, friendly, helpful, and smiled. I was impressed.

Flight was delayed. Crew was not helpful in the plane.

Flight attendant took my carefully folded coat and flung it across the aisle to the bin across the way. Where one of the passengers rescued it for me, because that just wasn’t right!!

the flight was delayed twice and then delayed from taking off.

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.

I am still upset that my bag was lost on a recent trip to Rome ; we were inconvenienced and out €150 Euros ; delta has refused to reimburse us

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

I love the free WiFi!! Crew was nice. Bathroom was decent. First time flying delta in a long time and I enjoyed it. Will definitely look into booking with Delta more but I think Delta is a little more expensive than the other airlines.

Seats are much much more comfortable than United, which is what I usually fly

If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.

Only one side of the heafphone jack work. Crew was friendly and helpful.

Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.

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.

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

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.

Its good expeince but in enternteiment please be like you tube the music i like or movie

I needed to make changes to my flights. When I called customer service, they assisted me with care professionalism.

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 ;)

headphone jack didnt work for the first flight and not much variety

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

Loved the staff, boarding and drink options! Wish the comfort of the seat could have been better nevertheless

Honestly, I haven’t flown American in years, probably due to the pandemic and my being unable to travel for certain periods in the last two years, but it was a good experience to dig out or obtain a new American Airlines account after many years of traveling for business with American in the past.

Long 5 hour and 45 min flight and only one drink service and cookie snack

One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.

Flight boarded from Gate 39 at OGG, the farthest gate in the terminal. There were no Hawaiian themed amenities for the flight. The first class service was mediocre at best; I received not special welcome or recognition as an executive platinum member of American Advantage program. The flight attendants were more concerned with their cell phones than saying "thank you" to the passengers as we disembarked. Fortunately, the flight arrived at LAX a few minutes early.

Bigger seats. Board back to front! Disembark front to back!

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

This flight didn’t happen because AA agents didn’t let us board the flight

Plane was pretty clean, staff was friendly and helpful, flight left about on time arrived early. Took a long time to board and get off the plane - carry on items didn't have enough room so people had to move all around to find places.

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

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

The worst. We never made our connection and they did absolutely nothing to help us at the airport.

Our flight was cancelled. They could do nothing to help us get another flight that was timely. Because the first leg was cancelled we were unable to get to our connection. We had to book on an entirely different airline for today. So we spent more money, lost a day of vacation and will never fly Frontier again, so the 'we are sorry, here is $100 credit' is a joke since we won't be flying on Frontier.

No way to get boarding pass on my phone. In order to print the bag ticket a boarding pass is needed. Asked the agent to print me one, they said they typically do not due this as its so much work. I showed the email confirmation and I asked how i could do it my self the agent replied he did not know as there was no link. The flight was delayed due to an attendant forgetting to come to work. On the flight no drinks were offered only for purchase meals.

Since you have to pay for overhead bags then they shouldn't be running out of space and asking individuals who paid to remove stuff from the overhead

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.

Book with frontier airlines with the mentality that they'll cancel your flight, kick you off and lose your luggage. Anything besides that is a win. Compare prices with other airlines (to include luggage) and if frontier is still worth it, book it but know all of their policies.

You get what you pay for nothing essentially but a hard uncomfortable seat that doesn’t recline and kids screaming all around you and chaotic boarding and limited check bag weight allowance when compared to other airlines

I never got to experience the flight because they delayed my first flight and I missed this one. Then Frontier didn't want to help me rebook a flight to get me to my final destination.
