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 
Verified travelerFlew with Alaska Airlines-Jun 2026
Expect to leave for JFK 3 hrs prior to flight if traveling by car from Upper West Side. You will want to arrive 1.5 H prior to departure
ClaudiaFlew with United Airlines-Jun 2026
Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future
mizueFlew with ANA-Jun 2026
Give yourself 4-5 hours of wiggle room because this route is frequently understaffed and the gates are far enough apart to make 1 hour very difficult if any issue should occur such as staffing or weather delays. As soon as a flight boards the airline staff are MiA.
MitchellFlew with United Airlines-Apr 2026
security access line for Premier access was very reasonable, process was less than 10-15 minutes. Leave time for dropping off a rental car - is a bit of a walk and then AirTrain transfer due to the current construction - so allow time for less stress. take advantage of the tables in the boarding area for charging devices or doing work.
ManishFlew with Air New Zealand-Apr 2026
Long haul so make sure to get up and move around a bit.
AgustinFlew with United Airlines-Feb 2026
Arrive early for your flight so you’re not rushing. And have plenty of patience with other people that are impatient.
MichaelFlew with United Airlines-Jan 2026
The Portland airport is very easy to get into (traffic, TSA, etc.) Sunday late afternoon/evening.
BeverlyFlew with JetBlue-Dec 2025
Wear support socks which helps when you sit for a long time.
Verified travelerFlew with Alaska Airlines-Feb 2026
I flew direct from Kona Airport. It's small, friendly . But on the obverse side loading did take a very long. Take a direct flight to San Francisco; connection is a terrible experience in Honolulu International Airport.
LindseyFlew with SWISS-Dec 2025
Ready for weather delays of wind in SFO, which happens often. Keep that in consideration when planning an additional leg of a trip after it from SFO.
SteveFlew with Delta-Jan 2026
Plan on checking your carry-on bag. AeroMexico has a strict policy on carry-on luggage for most boarding groups.
Verified travelerFlew with United Airlines-Feb 2026
1 hr is doable if you're transferring at sfo but probably just get something to go food wise
Verified travelerFlew with Alaska Airlines-Feb 2026
Dont wear all your clothes its not worth the discomfort to save on a checked bag.

Bring your own food and in flight activity since they don’t supply any.

Book a flight early in the morning. The plane & crew will have arrived the previous night
SanketFlew with Flair Airlines-May 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.

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 Airlines-Apr 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 Airlines-May 2025
That flights from Portland to S.F. with an international Eva air connect require checking in again before boarding

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 Airlines-Dec 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. :)

There is an agricultural inspection of carryon bags at the gate. Don’t try and bring home any pineapples.

Use their app, it’s great & they notify boarding, etc
JoanFlew with Porter Airlines-Nov 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 Airlines-Nov 2024
Nothing really, being clothes that are easily taken off like shoes at the security will always save time
JulieFlew with Alaska Airlines-Oct 2024
Leave early. JFK can be messy. I couldn’t find healthy food choices so eat before you arrive.
PhallyFlew with Alaska Airlines-Oct 2024
Don't take too much stuff. Make sure to have the necessary documents or boarding pass ready.
CandaceFlew with WestJet-Jul 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 Airlines-Jul 2024
Get your boarding pass online and save it to your wallet App on the iPhone. Makes it so easy
SoniaFlew with American Airlines-Aug 2024
Leave at least 1.5 hours between flights as Dallas is HUGE!
Verified travelerFlew with Alaska Airlines-Jun 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 Airlines-Aug 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 Airlines-Jun 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 Airlines-Aug 2024
Flying to the Ronald Reagan airport is closer and faster to D.C. than the Dulles airport.

Realize it’s a smaller plane and you will probably have to green tag any carry on.

Bring your own device. No screens on the seatbacks.

Please be prepared to check in your luggage even if there is available space in the overhead bins. Despite the availability of space, Alaska Airlines employees refused to allow us to bring our bags onto the plane and insisted that we check them in.
BrianFlew with United Airlines-Feb 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 Airlines-Feb 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 Delta-Dec 2023
Get there early. The TSA security line is very long.

My trip was delayed by more than two hours and missed my connecting flight to Fiji due to delayed they have to change my flight to United Airlines and stranded in San Francisco for 24 hours waiting for United next flight after almost 3 days I finally arrived in Brisbane airport but my luggage wasn’t here and now I still don’t have my luggage and still without my clothes and my needs. The first full day of my vacation is horrible because I don’t have any clothes and still trying to contact airline for luggage update and hopefully they will tell me the truth instead of misleading me and I end up waiting around without enjoying my vacation time here in Brisbane.

My trip was delayed by more than two hours and missed my connecting flight to Fiji due to delayed they have to change my flight to United Airlines and stranded in San Francisco for 24 hours waiting for United next flight after almost 3 days I finally arrived in Brisbane airport but my luggage wasn’t here and now I still don’t have my luggage and still without my clothes and my needs. The first full day of my vacation is horrible because I don’t have any clothes and still trying to contact airline for luggage update and hopefully they will tell me the truth instead of misleading me and I end up waiting around without enjoying my vacation time here in Brisbane.

I was offered a selection of drinks and given a free snack. The flight was only a couple of hours, but we were trreated better than the transatlantic flight.

The flight was very late departing the gate, for unknown reasons.

Alaska Airlines cancelled my flight the night before and then waited hours to let me know that they rebooked me on a flight 2 days later

The flight got delayed for some unknown reason to us. Then, after boarding, we stayed grounded for almost an hour without any explanation or announcement. Then, finally lifted off. When we landed and made our way to baggage claim. The luggage took 30 minutes to come! It was past midnight due to the flight being delayed and my litter children were cranky and tired! It was not a great experience. Perhaps, more explanation of what is going on with the flight would be helpful!

Our flught was rerouted to another airport 60 minutes from our destination. We were told we would get Lyft vouchers to get us to our original destination. We did get vouchers, but when we arrived at the rerouted airport, we realized the vouchers were for a Lyft ride from the starting airport to our original destination. We were lead to believe that once we arrived at the rerouted airport, we could use the voucher from there. Nope. So we got stuck with a $100, 1-hour Uber ride. The flight staff was annoying. We were seated near the rear, and for the entire flight, both attendants were gossiping about some drama on Facebook. And they weren't being quiet about it. The back dozen rows or so could easily hear their entire conversation. I've flown Alaska Airlines many times before and have never had problems. This was an awful experience.

delay was longer than the entire flight. I didn’t stop flying with delta for this.

I was very surprised that at the Seattle airport, Alaska's main hub, that the gates were very small and very close together, and it was very hard to discourage between my flight, and the flight next to us going to Boise and the flight next to that going to Denver. Denver. The audio for all three Gates was at the same level, and almost impossible to differentiate unless they actually said their flight number and location. Location. People tried to get on our plane, before they were ready, because they were confused about the Denver announcements. We were on a Boeing 737- 800 00, that must have recently been redone. It actually had USB--c ports which really surprised me. The Apu was out on the plane, so when we got on it was very very hot. A lot of people were complaining. The gate agents were very professional, but it was a lot going on and even though there were two of them, I think they could have used another person to help them. Mandy was particularly helpful in getting me a window seat. Flight crew was up to the usual Alaska airline standard, which is very high. Can we please get another snack then garlic pretzels? It would also be nice, if they knew ahead that the flight was full, to offer to let us check in our bags for free at baggage check, and not at the gate!

Very terrible/ never will I fly this airline again. Poor service in the plane. They cancelled a flight without booking another. All the way around it was too awful.

Terrible experience with an extremely obese passenger seated directly behind me - who snored and gagged so loudly, even throughout takeoff, that no one within ten rows could have gotten any rest even with earplugs! I get that this poor person has a serious health issue, and that Alaska (maybe) had no way to prepare in advance (though he did occupy two seats). Still there must be a way to take a six-hour flight without feeling like I'm next to a roaring grizzly bear.

The flight was done by SkyWest only WIFI no entertainment center are available on the CRJ

Delta is always late. Ruined our first day of a short vacation. Timing is important. We pay to stay on an itinerary

We sat on the runway for over an hour before departure. That was unwelcome.

Everything went smoothly, although the usual gripes about airline travel were still present: the boarding process is inefficient, the snack selection is limited, and so on. Since there was extra space on the flight, the gate agent rearranged many people's seats to put people on the aisles and windows, leaving the middle seats empty, as much as possible, which was pretty great.

One of the flight attendants was a little cranky. I appreciated the free wifi and plug to charge my laptop

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

Generally on time departures and arrivals, clean planes, sky miles membership provides great benefits (complimentary upgrades, etc).

my mom urmila patel needed a wheelchair which was not available on the curbside. she needed to walk almost 50 meters inside (at the risk of falling) and then had to wait in line to get a wheelchair (this is not ok). Once obtained she had to seat in it for 30-45 minutes for someone to take her in thru the checkin process (which was fairly smooth and easy). the lady who helped her with her checkin process was very courteous and helpful

Awful - both legs. The check in was awful, getting on the plane required walking down a spiral staircase (dangerous), then taking a bus about 5 miles out from the terminal. The seat was broken (I was in business), there was no internet during the flight (both legs). The aircraft was very old. I saw rust in some place, tape holding things up in the bathroom. This was an unacceptable experience for such a long haul flight.

I usually get upgraded so my experience is usually amazing. I did not get upgraded this time - which was fine - but the wifi had issues, the monitors were going in & out, & (though not Delta's fault) one of the gentlemen next to me desperately needed a shower.

the seat has a problem. the back had a hole.

The entire experience convinced my wife, Cathy, and me that traveling Polaris on United is the only way we’ll fly in the future. From check-in and baggage drop to the end of the 12-hour flight, the customer service was exceptional, with numerous staff members exemplifying the very best in care. On board, Andre, our primary crew chief, was sincerely friendly, a consummate professional, and, along with Freddy, one of his team members, truly among the best of the best. The captain even came through the cabin to chat with passengers—a wonderful personal touch, especially on such a long journey.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

We boarded the plane and were about to take off when we were notified that the tires had to be checked. Upon inspection, they were found to need replacement, so the entire plane had to be deboarded. After we exited the plane, United staff forced us to stay in the gate area by posting "Do Not Exit" signs on the doors connecting the gate area to the terminal. Many of us had already rebooked our flights and had no checked bags, but they told us we could not leave. This seemed inappropriate to hold people under false pretenses. When the agent told us we could leave, I asked them to please take down the "Do Not Exit" signs, as they were misleading. The agent refused, and I told them that it didn't feel right to hold people like that.

There was a piece of plastic baked into my buttermilk biscuit! I have a pictures. The flight attendants in first class were really apologetic, and tried to rectify the situation. I I am very appreciative that they were able to give me some packets of pretzels and gummy bears. I understand they don't personally handle the food until warming it up so I know it wasn't their fault. I don't know whether it was a newer aircraft, or different food packaging, but I was happy that when the food was being warmed up - it didn't smell like plastic. Jokes on me with finding plastic in my food.

United was excellent. We had very good experience flying the carrier. Certainly. We will opt to fly them for sure. Lufthansa is out.

The seat that I got this time is really good.

Excellent flight. On time. Great staff. Clean and crisp cabin.

The Manila airport was under renovation so there was no business class lounge. The double security check was disorganized and the flight attendants were grouchy.

Our experience with American Airlines was extremely disappointing and honestly made an already exhausting international journey much worse. After flying all the way from Melbourne and dealing with significant jet lag, the American Airlines experience at LAX was the last thing we needed. The terminal and boarding area felt very old and uncomfortable, with little to no air conditioning and only old fans running in the area. Boarding was also through outdoor stairs rather than a jet bridge, which felt especially inconvenient after such a long journey. Even though we were traveling First Class, the onboard experience was surprisingly poor. There were no meaningful snack options, no decent coffee available to order, and the aircraft was so small that there was barely enough overhead space for carry-on luggage. The staff experience was also disappointing and lacked the warmth or attentiveness we had experienced on our international flights. To make matters worse, the flight departed late, extending an already very long travel day. Overall, the combination of the outdated terminal, uncomfortable boarding process, limited First Class service, small aircraft, poor staff experience, and delay made this an extremely unpleasant final leg of our journey. It significantly worsened our exhaustion and jet lag rather than making the connection home easier. Unfortunately, this experience was bad enough that I do not plan to travel with American Airlines again in the future.

Horrible. No AC. No Air inside the plane. We had to deplane twice! It is late almost 5 hrs in total. I almost passed out and about to call 911. I asked the crew to be honest and open the door. The lady next to me was lay down in the floor due to heat and no air inside the plane. I got headaches, can’t wait the replacement flight about midnight Dallas time. I end it up rebook for next day flight and stay overnight using my own pocket in a hotel nearby due to headaches and can’t breath. I still have a headache this morning. Still not decided yes how to file this issue to AA and/or FAA.

I could not ask for more. Great service and experience.

Initial flight had an engine overheat - returned to DFW. Had another plane ready, but crew timed out. Had to wait 5h for boarding. Fully boarded and pilot says plane is not flight worthy. Deplane and go to the other end of the terminal. Wait an hour to board third plane because the crew couldn’t leave the second plane because no wheelchairs were brought to remove passengers. Finally take off and there is no catering (in flight service) even in first class. Very much an AA failure.

The food was good. I almost didn't get a seat on the flight unless I agreed to sit in emergency exit.

The flight attendant was very polite and attentive. The food was good.

I had a comfortable and enjoyable experience. The entertainment options were plentiful, the food was appetizing, the snacks were tasty, and the staff was friendly, professional, and helpful.

Was put into a seat right behind the toilet that had no entertainment possible but did have plenty of leg room over noisy part of plane.

Flight: Started on time. Comfortable flight. Arrived on time. Crew: Very cordial and helpful. Drinks and snack was served with a smile. Overall enjoyed the trip. Regards, Hari Doss Chanchala Doss

Buying ticket from kayak instant booking was a huge mistake, never to be repeated again! The Kayak didn’t book the tickets directly, it handed it off to a third party Underpricer, that booked a code shared American Airlines flight operated by Cathay Pacific!! When managing the booking American Airlines would recognize the itinerary but wouldn’t let me do anything stating, the flight is operated by Cathay Pacific so go to their website. Cathay Pacific would recognize the itinerary, neither by reservation ID or ticket number…asking to reach out to the third party Underpricer….calling Underpricer resulted in no help like seat requests, mileage number or upgrade request, 15hr layover accommodation voucher guidance…so net in net avoid booking through three layers of intermediaries

Charges unexpected. For seat that didnt recline. Please reverse extra seat and carryon charge. Bad business that is a bait and switch.

I couldn’t check in because the app didn’t work. It took 3 Frontier employees at the counter to get me checked in. Flight left 3 hours after departure time

Horrible! The short distance flight ended up taking 5 hrs! There was a 3 hr delay for the flight to take off and there was a 70 min wait on the tarmac for some bogus reason that the pilot said the gate he was supposed to board was taken up. After a 30 min wait he said the plane that was supposed to push out of the gate called a medical emergency and 40 min later he ended up boarding another gate. For the initial 3 hr delay there was no information/alert about the gate or delay in the app or the boards up until the boarding time and even beyond! Had to walk all the way to the end of the terminal to find the frontier staff to ask what was going on. Avoid this airline at all costs! If you have carryon bags or checked bags , their prices come equivalent to the prices of more reliable airlines. They are the worst in timeliness at 60% (reported as delayed) this year (check the data) by a high margin even compared to the second worst airline. If you are ok with having a miserable flight experience with the odds close to flip of a coin, feel free to try them. If you value your time , money and flying experience, stay away.

Our flight was delayed by four hours without notice, the app for getting my boarding pass is super confusing, and I wasn’t able to check a suitcase without paying for a higher cost package

First the gate was a total nightmare-no chairs anywhere! So over crowded and only one bathroom and nightmare of food service - took forever and NOT one place to sit. No inflight entertainment and had to pay 60.00 for a small carry on. I will never fly Frontier again!

Flight was 3 hours late leaving. Poor communication from the staff about delays. Impossible to get in touch with customer service (by design). And it actually didn't come out to be much cheaper than a non-budget airline! Not worth the headache, I'm never flying Frontier again

See my previous comment which is mostly about our flight from Phoenix to SFO

The check in at the airport was awful. Told I need to pay for a bag. The item was taken at screening. I went back to get my $ back and they gave me a coupon with a QR code that doesn’t work. Worst costumer service ever!!!!!

4 hour delay because they used our aircraft to fly a different segment (per the captain)

absolutely horrific. delayed flights, overbooking. over charging. nightmare service beyond words. stay away.
