Flights from San Francisco to the United States: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from San Francisco to the United States 
ElenaFlew with United AirlinesSFO-EWRJun 2025
Construction in the terminal so allow for extra time in SFO. Very easy finding luggage and getting outside at Newark. Also, this time, took the Express Bus into Manhattan - $25 is a good price, though the bus arrived 20 minutes after the scheduled time.
MaryannFlew with United AirlinesSFO-EWRMar 2025
Bring your own food with you. Airport and airline food is expensive and you WILL need something to eat on such a long flight.
LawrenceFlew with United AirlinesSFO-HNLMay 2025
Get to your gate early!!! Very little seating at/near gates 19, 20, 21 and 22. The last couple of flights, American boarding (very different gates) has been very straightforward. The last time on United, boarding at gate 19 was bedlam. Really going to look hard before scheduling on United next time!!!
SarahFlew with Alaska AirlinesSFO-BURFeb 2025
Go early in the day so if your flight is canceled, you might have better alternatives than I did when my 12:30 flight was canceled.
Verified travelerFlew with Alaska AirlinesSFO-AUSJan 2025
Use the lounge access at the discounted rate. It was very nice.
ericFlew with Air New ZealandSFO-BOSJan 2025
At least two hour connection Buy food pre-flight
GeraldFlew with Alaska AirlinesSFO-ORDOct 2024
Book a flight as early in the day as possible to avoid incoming flight delays.
StevenFlew with SouthwestSFO-LASOct 2024
Take later flight out side of the hotel check in time. Lines are terrible. Travel light.
William DrewFlew with Alaska AirlinesSFO-HNLNov 2024
Arrive at least two hours before your flight.
BrookeFlew with DeltaSFO-MSPJun 2024
Book early for the best price. Upgrade if you can. Sun country is a more consistent experience but delta has better in-flight entertainment.
IreneFlew with SouthwestSFO-LAXJun 2024
Arrive a least 1 hour before boarding if you’re checking bags. Light layers due weather variation
JohnjimyFlew with ANASFO-LAXAug 2024
Layover from NRT(JPN), to SFO (US), to LAX(US) Easy if you are a United States Citizen, when you go to US Border & Customs, bring your Passport if you arrive Internationally. Remember to pick up your check baggage before moving into domestic flights, as they will check the tag for the plane you are boarding in. (They will check your baggage again). Bring your ID/DL (Real-ID COMPLIANT) with you to pass security/TSA, passport works too. SFO is pretty strict as well as LAX.
Verified travelerFlew with Alaska AirlinesSFO-SEAJul 2024
It is a very crowded flight, so I advice to choose seats in advance. We didn’t have that option and that was the only complaint I’d have because they put us in the middle seats and we both wanted aisle seats. My sister was able to switch but I wasn’t. She was switched to the back, almost to the last row.
Verified travelerFlew with Alaska AirlinesSFO-PSPJun 2024
SFO ~ most convenient People should prepare themselves for cold temperature inside the cabin, bring coat/jacket and food in case flight is delayed.
NancyFlew with United AirlinesSFO-ATLAug 2024
Bring your own food, shorten your legs by about 4-5" and bring your own entertainment that is not relying on any internet.
FatimaFlew with FrontierSFO-LAXJun 2024
Frontier requires 3hr preflight check in even on domestic flights
RobertFlew with Alaska AirlinesSFO-EWRJun 2024
Bring some food on board for the flight
JulieFlew with SouthwestSFO-LAXJun 2024
Avoid flying into LAX. It’s a nightmare. Baggage claim took 40 minutes. And then the shuttle to the car rental place took an hour because there are two shuttles. The first is a local bus that makes a stop at every seven terminals and then it takes you to another place where you have to wait for your smaller shuttle to the car rental place.
BryanFlew with American AirlinesSFO-DFWAug 2024
Don't count on wheelchair assistance, particularly if you have a short connection and different terminals. DFW is HUGE and the assistance program is a disaster.
Verified travelerFlew with United AirlinesSFO-DENMar 2024
Get TSA PRE and CLEAR. Life will be easy.
KateFlew with Alaska AirlinesSFO-PSPApr 2024
Fly in the morning when it’s not windy.
SidFlew with United AirlinesSFO-BZNJan 2024
wear layers as you never know if you will be cold or hot (with non-functional vents).

Plane boarded and left on time or very close to the stated departure. Arrived on time. Staff was subdued. Could not hear the flight attendant too well. No announcement from the pilot which is always nice. Biggest complaint absolutely no little snacks! But the important thing is we left and arrived on time and we survived.

Crew was not happy to be there and neither was I 😭 well at least the lady that helped me.. I was stuck in the middle seat between two men. Totally my fault since I didn’t pay a fee to select my seat though. I recommend paying the fee even if you’re in a budget. It’s better than being placed aaaaallllllll the way in the back next to the smelly bathrooms. The seats didn’t recline either!! It was a red eye flight so I got no sleep whatsoever. Ordered a coffee and it tasted like…. Let’s just say it was horrible. I had to to return it to the same crew lady and she looked at me like this girl…. Sorry but I was not going to drink that- please take it back!! Oh and lastly, my luggage was completely broken and damaged. All wheels were missing by the time my luggage came around in the luggage cart. Lmao. Overall poor experience to say the least. Tickets were cheap though😂😂😂

Delayed flight both ways. Then, on the return flight, we were stuck on the tarmac for at least 30+ minutes. Idk what happened, but this was a bad experience.

Great flight, no bumps to speak of, pleasant crew, good inflight entertainment choices

Coffee or tea service would be nice for an evening flight, water or juice not good enough.

this flight had a 7 hour delay due to weather in NYC. It diverted to Pittsburgh for 2 hours then proceeded to NYC. Through it all the crew and flight attendants were terrific. They gave timely information, showed empathy , and were very professional.

Paying for first class and then they want $8:00 for wifi.

fine. only problem,,,, for some,,,,was that many people started trying to exit from the back of the plane,, . lots of irate people. there should be a flight attendant mid plane..to be sure that doesn't happen. The crew up front had no idea what was happening. One big guy started it..then a bunch of others followed his lead. could have gotten ugly... One man stepped in and questioned those rule breakers.. nothing bad happened,,,but......

Big delay of over 7 hours on next leg of trip with Alaska. Would have been nice to have food or something

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.

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

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

There was a security issue at the airport and we were unable to land. We circled endlessly and then landed at another airfield for fuel. We then circled the airport again, almost landed but didn’t fully touch down before circling again. I am thankful to the crew for keeping us safe- the issue was the airline and staff at the airport getting us seats on our connecting flights. That part was hours of searching for someone and getting in double my steps.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

Delta flight was on time, seats were comfortable, and crew was nice.

The pilots were late and it made us 1 hour late. The meat was tough and bok choy was also tough.

Stuck on tarmac for two hours plus a 5.5 hour flight. Rude flight attendant. And no meals, not even for purchase!

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

The best airline I have ever travel , really good customer service, attention and service !!

Everything was great. Only thing that could’ve made it better was buy on board options for hot food, but the snacks were decent. The flight attendants were great. I had no complaints. I was able to make it to my destination safely

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.

Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.

4 hours late, including over +1 hour waiting in plane to take off. Baggage left behind too.

While waiting to claim my checked luggage, I discovered the airline had lost it. After a long wait and inquiries, I discovered it was on another flight. Fortunately, the airline finally sent my luggage home.

Was not able to watch most shows on the entertainment site. They would not load

Our flight was 1.5 hours delayed. There was no weather for the inbound flight, so I don't understand why. This meant a VERY late arrival and only a quick nap before my morning flight.

Delayed flight, so I switched fights to SFO to Phoenix , Phoenix to DSM. Excellent service through American Airlines

AA re-routed flight from HNL to LAX due to delay. My group of 3 with reserved seats in row 9 was broken up, with one assigned to a middle seat, another in the last row of the plane. Not happy. No explanation to the delay. No apologies. No compensation. Would have been nice to be offered an Admiral Club admission or a voucher for the extra 3 hours of layover in LAX. Could not hear the boarding gate announcements in LAX. Adjacent gate was boarding at the same time. Loud speakers were competing against each other. Barely made my boarding group.

Almost a 6 hour flight and the only food option is a cheese plate… and chips. Also how is it there are no options for texting on American. I’ll be going back to delta and united.

The chair cushions may need an upgrade. I have been noticing they are so worn out, thin so you’d sit in a dip 😄. Other than that, all was an enjoyable trip. Thanks AA!

Cramped seats. FAA should make airlines have more legroom, for even short people complain

Eventless. It was a good flight and good crew. Can’t complaint.

sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.

Disaster. They lied every step of the way. We ended up being delayed due to crew and then allegedly abandoned the flight because of a curfew at LGA. No rebooking to LGA at any reasonable time. No hotel. No meal vouchers. Had to sleep in the airport and fly to Newark instead. Will never fly Frontier again.

What I expected, nickeled and dined and a frontier flight attendant loudly complained about her job and lack of communication as she headed to the gate on her cell phone. Not professional.

As every law enforcement agency I could imagine surrounded the plane and we didn’t disembark for 2 hours and then had to stick around for another hour to go get our personal belongings after leaving them behind and being bused away from the plane, it was scary and inconvenient. We were given no information as to why this was happening. Lack of communication with passengers was disappointing.

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.

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….

Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.

Flight was delayed 3 times, would have been nice to have received text message instead of email notifications. Frontier app wasn’t even updated accordingly, no gate number disclosed. No agent at front desk of gate to inform of delay. Very confused and left if the dark
