Flights to San Francisco Bay Area: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew to San Francisco Bay Area 
MichelleFlew with Aer LingusDUB-SFOMay 2025
Make sure you arrive well ahead of the flight. We were lucky that security lines were pretty short but they could be very long and you do US customs and security in Dublin.
NinaFlew with Aer LingusDUB-SFONov 2024
Make sure you include extra time to pass through US Border Control if you’re flying to the US! Also Aer Lingus bag drop closes 75 mins before flight departure for long haul so bear that in mind!

Boarded plane and then delayed 1.5 hours while on the plane

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

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.

My flight was delayed a very short period of time but they did not hold my connecting flight to San Diego, also through United. So they closed the doors before we got off our plane. They would only have to help the door open for another five to ten minutes. So I missed a court deadline for a manditory mediation settlement conference for my client. I had to get an associate to be there in person and be on the phone with him relaying what he needs to do the entire time. The court was very upset with me and so was my client. United cannot be trusted.

We were given vouchers we couldn’t use with a 5.5 hour delay

Really good 😊 the woman at the gate entrance was a little rude checking in our carry-on but i dont think she worked for the airline, she worked for the airport at sacramento, other than that amazing.

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.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

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.

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan

Boarding gate in Honolulu was staffed with a great clerk with a soothing voice despite the flight delay of over an hour. Flight attendants in the plane were all grumpy, not pleasant looking bunch. Their sour attitude showed throughout the flight. Inly able to get a select few movies started. Most of the movie links in the “free entertainment” did not work.

I flew Business Class. Rory, one of the Cabin stewards, was attentive, explained the menu, provided appropriate drinks. was

This was a horrible experience. For a first class experience, my chair was held together by 3M tape - and I have a photo. The crew weren’t very attentive, somewhat dismissive and forgot my drink and snack, the chair reclined about 3 inches on a 6-hour cross country flight. I was also not informed that there was no lounge available in Newark airport because of renovations, so all around this was one of the worst experiences and I would actively avoid both American and Alaska Air going forward.

Boarding was very efficient. Everyone got on board and we got on our way very quickly. It was frustrating that the entertainment app was not functioning properly. I was not able to activate some of the movies offered. The crew on this flight appears to be pretty grumpy. They had no smile on their faces. I felt like they were doing us a favor for being there.

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.

Good flight, friendly crew and overall - good service on United Airlines.

Somebody either kayak or Air Canada booked my flight under my preferred name Betty instead of my legal name and I almost was denied boarding my flight

Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.

Comfortable seats and movies entertainment available. Better experience than the flight from Toronto to Denver.

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not

Mixed experienced. Nice staff. Spacious 787 better than cramped Airbus, though my seat was broken. The bad: Way overpriced ticket and charged for food despite 6 hr flight.

Terrible all around. Flight was late and airplane was very uncomfortable. The crew were unhelpful and hid in the back. Did zero work. No entertainment.

I booked and paid extra for exit door seats also pre paid for my luggage air Canada changed plains and I never got what I paid for and they made me pay for luggage again they also did this to my wife. They are the most unorganized company I have ever dealt with. I am sure I will never see the extra money I paid for the seats or the recharge for the luggage. They are subsidized by the taxpayers and don’t give a dam just a horrible way to do business

Overcharged by either United or Air Canada. Abuse of access to my credit/debit card.

Your crew was so so so wonderful Only thing sound be great if you kept some phone chargers and converters rest 👌👌👌👌

Dublin to Boston was decent. Food and entertainment was included and that was expected for the rate paid.

No entertained. food and beverages were not complimentary. they lost my checked luggage which made my 10 day vacation unpleasant.

Flight was on time. Boarding was quick and efficient. Seats were comfortable. Food was fine.

Seats were less comfortable and tight from Newark to Dublin, than my second flight ( small segment from Dublin to Lyon). Movie audio was with frying sound overall. Yet the worst was as follows: one male, (dark hair , glasses on) from the crew member was so cold and rough, while I remained with constancy polite and kind. Per exple with the noise level I could not hear him at first for beverages, he rolled his eyes at the third times I finally heard him. From the start, loading my small hand bags , he directly spoke to me and said “ I had to keep my shopping bad by my seat, under , while there was sufficient room and I was among the last to sit. I show him the space , his face was always dull, stoic, not welcoming as the usual crew members from any airline companies are. When I think of my experience I liard w Aer Lingus, this is the image that gets back to me. Needless to say that as a passenger and client, I felt belittled since all this happened in front of the surrendering passengers. It s an affront and not a pleasant feeling especially when being traveling which oftentimes involves stress with carrying, and making it on time. I m not happy with the experience I had to be honest and I fly four times a year. Thank you for allowing me to share this statement with your company.

I like Aer Lingus so that is why I’m writing this critique so they can become better. The boarding gate was too small to board properly. Our seats were toward the back of the plane knowing we would be boarding after business class, we moved to that area after business class boarded. An Aer Lingus employee told us we couldn’t stand there. We explained we were the next group to board and wouldn’t even be able to hear when our boarding was called. She didn’t care and was not very professional. The cabin was freezing. I wouldn’t feed my dog the food. We were over an hour late coming into chicago because of weather which can’t be avoided. I asked the crew if they could make an annoucement for before whose final destination is chicago to wait and allow the people with connecting to deplane first. He said there are a lot of people with connecting flights. He said, it doesn’t matter. Well, yes it does. He could have been more considerate of his passengers.

The seat spacing was good. The food, not so good... typical airline food. 😕

I would face like to have more selections for entertainments overall it was very good. .

One cold drinks service. No snacks with drinks. No tomato juice or apple juice, coke - only fanta or sprite then ran out of that. Went to gally after meal service no one there / no self service for water at least. Waited 25 min for cabin crew to assist. No recycling of cardboard/ plastic - all put to garbage. Breakfast was a nutrigrain bar and an orange juice. Also I'm sure I booked a flight with checked luggage allowance but had to buy extra when I had my booking confirmation. Movies were good. Chairs comfy. Pillow and blanket and ac vents.

I would definitely use a Linus again, the price was right, the service is excellent. No delays. Wish I had a direct flight from my hometown Detroit.

At check-in the unmanned machines said QR code was invalid so had to queue for over an hour to check in bags

The crew were good. The flight was on time. The entertainment choice was ok. But the food was bad, tasted and texture were awful.

After boarding we were waiting in the plane for more than one hour to take off without AC with very high temperature inside

The flight was an hour late leaving Heathrow. The food was mediocre. When we got to Austin, my husband’s luggage was missing. He filled out information at baggage claim. We are waiting to hear something. His name is Henry Jacob Braunig.

The food was very good and it came multiple times

Flight from LGW to JFK delayed by 4 hrs No explanation given until the pilot said the delay due to planned maintenance on the aircraft

We arrived late to London, and consequently were 5 min. late to be allowed through security for our next flight. Even though dozens of people missed the same flight, BA did not radio ahead to hold open security for an extra 5-10 min. to allow people to get on the flight. This caused an additional 6 hour delay in London after waiting over an hour in Customer Service to get rebooked. They did not have enough staff on hand to help people in a timely manner. Not at all happy with the BA's customer care or customer service.

All service prior to the flight was terrible: online check-in not working, no customer service tel,, multiple airport scanners not working, A huge mess.

CONSTANT ERROR MESSAGE THAT THE WIFI COULD NOT BE PURCHASED DUE TO INABILITY TO CONNECT PAYMENT SYSTEM VIA SATELLITE. THIS HAPPENED IN BOTH DIRECTIONS. THE MAIN REASON I TRAVEL IN PRIORITY IS TO BE ABLE TO WORK FOR WHICH I NEED ACCESS TO INTERNET. .

They lost my luggage. Lady who was helping with it in Austin was rude. Not very helpful!

Waited 3.25 hours in plane only to have the flight cancelled.
