Find Cheap Flights from San Francisco to United Kingdom

Cons: Icelandair has decided to make tickets cheap and baggage charges outrageous. My fault for not reading more carefully but I will not fly this airline again.

Pros: Very helpful and courteous flight attendants; low fare; ability to reserve a seat when ticket was purchased. Leg room was good.

Cons: No procedure for boarding except to have everyone pile up in one mass. The staff at the gate seemed irritated that we had not had our boarding passes clearer at the counter, even though we had no bags to check and the boarding pass directed us to go directly to the gate if no checked bags. We had to stand aside while the inpatient staff cleared us. Naturally as more passengers went ahead, we had to search hard for a place to stow our carryons.

Pros: The movies!

Pros: Staff

Cons: Same old movies Back row Seats didn’t go back

Pros: The in flight attendants were very helpful and attentive. Boarding was quick and organized.

Cons: The entertainment system didn’t work well to start, and then stopped working altogether 2 hours into a 5hr flight. The staff tried to fix it and were very apologetic, which made up for it. The seats were a little too hard for me. I was pretty sore by the end of the trip.

Cons: I used Kayak to find my ticket and fill out my information (all kayak logos on top of the page and so on). However, when my confirmation email and e-ticket came in, they were issued by Budgetair.com. I had no experience with them and took it to be a reliable website since they were working with Kayak. However, I had to change/cancel my flight because of delayed passport delivery, and this is when everything turned very Ugly! I had to spend an hour over the phone to get connected to an agent with BudgetAir, who disconnected the line within 2 minutes saying: “please hold so I can pull up your information”. This game went on for 6 hours. I tried to connect with the airline directly to make the change, which was not possible since Budgetair had placed a restriction on this ticket. After 6-7 hours, which meant no work for me or lunch because I was sitting behind my desk with a phone on my hand, I got through an agent who was rude and impolite. He took 15 minutes to find flights for the new dates (I did it in 2 minutes on their website), and then told me to pay $315 in extra fess. When I inquired that the prices on your website for the exact same ticket is way cheaper than my original ticket price, he got angry and aggressive. Basically implying that I have no choice to take their offer as is, or let go of my original ticket price of over $2000. Long story short, DO NOT buy from BudgetAir if you like having a peace of mind!

Cons: Terribly small seats

Pros: Meals, comfort, polite staff

Cons: Nothing

Cons: No leg room, flight attentend ignored me twice and I had to get up to get a answer from him.

Pros: Flight was half empty, room to spread out

Pros: Finnair cabin/seats, clean, quiet and comfortable airport in Helsinki

Cons: Not only the first flight got delayed for over 2 hours. I had to re-book the second - connecting - flight because of that. Now it made my layover instead of 1 h 45 m - 5 hours! Then the second flight got delayed!! So instead of 5 hours layover it was over 7 hours!!! Very inconvenient and upsetting experience. The only reason I booked these particular flights is because they were advertized as "the shortest trip" time on your website...

Pros: The crew was helpful and polite, food was good

Cons: Would have preferred to watch one comedy movie. The crazy rich Asians was on a lighter side of a movie but I had seen that one already.

Pros: The plane left on schedule.

Cons: I was asked to check in my carry on but I couldn’t do it bc I had lots of fragile items packed. I was told that overhead compartment was full which was not true as there was a lot of empty space left.

Pros: Everything was wonderful. Staff was courteous, plane was great, food on the flight was exceptional. Compared to Icelandair, this was a dream!

Cons: N/A

Pros: Crew was very professional, food options were excellent.

Pros: The crew was exceptional, taking care of each individual passenger. Requests were answered immediately, not that really much was needed other than perhaps an extra coffee. Very roomy seats made for a very relaxed flight and entertainment was excellent. I will definitely choose British Airways again.

Cons: The only thing I thought could use improvement were the headphones. The cable could use 2 more inches in length and I was not a fan of the breakfast choice.

Pros: New business class configuration on Dreamliner - love that Virgin gives out pajamas, staff are always incredibly nice

Cons: Seats are surprisingly narrow, and lack privacy

Cons: Lost my both bags in transit. Also, did not get wheelchair services at Paris and had to walk everywhere with bad legs. Not good.

Pros: Inflight experience was fine. TVs didn’t work but Flight attendants are friendly on Delta, cramped seating - but not unlike other airlines.

Cons: Regular fare seat assignment not available prior to gate . Airport concourse F - poor - limited services. Customer Service seemed uninterested and unable to provide service both on phone and at gate. I’m a frequent United flyer & today’s Delta service experience made me more loyal to UA.

Pros: No surprises. On time. Courteous. I suppose the most amazing thing is their app. It tells you when your bags get on! Also I forgot that I had a knife in my pocket. I ran back to the desk and she went back, found my bag, put the knife in there. Wow. What service. Also I notice that Atlanta is a lot nicer than it use to be. Attendants are more friendly and loading is more organized. Way to go Delta.

Pros: Cabin much too hot and no air circulation until just before pushback. Ack!!

Pros: On time and pleasant service .

Cons: The problem was outbound from Porto to Rome. Iberia lost 2 out of 3 bags and one took 24 hours to reach our Rome hotel and one took 48 hours to reach our Rome hotel.

Pros: They have badest customer service becouse i want extended my way back to chicago they did not talk to me as customer but every time call they hand off the phone more then 3 times i will not fly again with this plane

Pros: Everything was delightful, definitely my best ever flight!

Pros: Arriving early Decent food

Cons: Taking off late

Pros: The service and quiet ride

Cons: The headphones did not work

Pros: Crew was good

Cons: No entertainment at all, food was bad

Pros: New plane with very friendly and helpful attendants. Extensive entertainment system with usb charging ports.

Cons: Food was mediochre, but what can you expect?

Pros: Flight was on time. Friendly crew and professional.

Cons: I ordered vegan food, no meat , dairy free. On my trip from Boston to Zurich I received vegan food. On my way fro Zurich to Belgrade I was told” sorry we do not have any vegan food, “ Also, I was charged $60 for my check in one bag,. Not expectable.

Pros: The crew were personable and the chocolate that was offered near the end of the flight was a nice touch.

Cons: Cramped, cramped, cramped!!!!! The seat pitch was just so uncomfortably short so much so that when the person in front of me reclined his seat, the TV screen was a mere 1-2 feet away from my face making it impossible to watch anything without getting crossed eyed or a headache. This unfortunate situation has influenced this review greatly particularly because this wasn’t a 2 hour flight but a long haul one.

Pros: From start to finish, Sevdije was in great hands. She had to be in a wheelchair, and there were three connecting flights in countries where she doesn't speak the language. It could have been so complicated, and everyone made it SO EASY. She was all smiles when she arrived in Boston. THANK YOU!!!!!!

Cons: Nothing!

Pros: check in & boarding were ok

Cons: very uncomfortable chairs worset food crew were very unfriendly the plan was full with the smell of vomiting

Pros: airplane

Cons: SERVICE. ORGANIZATION WAS AWFUL. TWO HOURS TO CHECK IN.

Pros: The comfort of the 10hr flight

Cons: Not that many movies on selection

Pros: Dreamliner is a comfy plane, good seats w/ decent legroom.

Cons: Food options. Not good choices, overpriced, and they ran out of many options on both flights. Poatao chips stale, terrible corn curls. The only main dish vegan oprion was cup o noodles type soup whivh was bland. I didn,'t know about ordering meals ahead, where I would have had more options. 11 hours is a long time to have such poor options.BRING YOUR OWN FOOD! Water should be offered free of charge- hydration on a long flight is important.

Cons: I didn’t know I had to pre-order my meals. Also, the entertainment selection was very limited.

Pros: Good price , good career

Pros: I always look forward to flights on Aer Lingus

Pros: Crew and food is good...especially out of Dublin..

Cons: maybe get thicker seat cushion

Cons: Lost my luggage

Cons: Didn't like having to climb stairs into plane with two hip replacements and luggage, and no assistance. The seats are tiny (and I'm a small person). The food was mediocre, passengers took their own food on board. The entertainment was pitiful for such a long flight. Very disappointed and probably will avoid Thomas Cook for future trips. Plus, It was very cold with constant cold air blowing on me; they provided no blankets, even though I requested one.

Pros: Food was excellent, same as Service

Cons: Plane sat idle for an hour while the crew cleaned up, with additional SFO airport delays they managed to miss 90% of their connecting flights, including mine. Had an additional 5 hours added to my schedule. I was assigned a "premium cabin seat" and I cam out with a backache, can't imagine what the poor folks on economy class had to go through.

Pros: The crew was excellent and the flight itself very comfortable

Cons: The entertainment did not work but sporadically.

Pros: Staff was courteous and helpful. Considering how crazy busy the Manchester UK airport was in August all went smoothly, boarding was efficient. Seats were okay but not too roomy for a larger person.

Cons: The (only) tiny movie screen was at the front of the cabin and. impossible to see for most passengers.

Cons: None of our 4 checked bags arrived with us. This was despite ample connection time (2+ hours) in Amsterdam.

Pros: short, sweet and to the point. 1+ hour flight is usually an easy hop.

Pros: The constant smile conferred by flight attendants through the entire flight.

Cons: The boarding was a bit disorderly. Lanes for zones 3 and 4 were not clearly indicated.

Cons: Landlords gave an unpleasant service! Which continued with late of 50min of the flight, they didn’t do anything to help/ to provide the passengers the answers. The food was cold It was comfort place to sit. Bad experience with KLM

Pros: Very helpful and courteous flight attendants.

Cons: Chaotic boarding process, like cattle all in one mass. Frustration of short transfer time exacerbated by failure of the scanners to accept the boarding pass, slow handling of passengers by gate personnel, lack of overhead storage required me to check a small carryon bag.

Pros: Every flight was on time as scheduled. Icelandic Air was great.

Pros: No baggage but flight advertised as Evonomy standard, that includes 1 checked bag.

Cons: See above.

Pros: N/A

Cons: Our flight was delayed 3 hours and we were instructed to rebook. After waiting over an hour to talk to an agent, we were supposedly rebooked to an Air France flight. After rushing to another terminal, the Air France check in agent told us she could not find our tickets, although the Icelandair agent gave us written confirmation. After being sent to the Air France ticketing agent (another office), we were told we were on a British Airways flight. COMPLETELY DIFFERENT AIRLINE. How were we supposed to know this? This was extremely frustrating. But BA treated us great and we can now see why they have such a great reputation.

Pros: Was on time! Not croweded!

Pros: Finnair cabin/seats, clean, quiet and comfortable airport in Helsinki

Cons: Not only the first flight got delayed for over 2 hours. I had to re-book the second - connecting - flight because of that. Now it made my layover instead of 1 h 45 m - 5 hours! Then the second flight got delayed!! So instead of 5 hours layover it was over 7 hours!!! Very inconvenient and upsetting experience. The only reason I booked these particular flights is because they were advertized as "the shortest trip" time on your website...

Pros: I last traveled on British Airways in May of last year (2015) and the food was beyond dreadful. Therefore I was very pleasantly surprised that there has been a huge improvement. They were very generous with the drinks and the food was plentiful and quite a reasonable standard for airline food (they gave two full meals from San Francisco to London, whereas most airlines give one meal and one snack on that route). They actually checked us in on the earlier side, we took off very promptly and got to London early. It was nice to be on time for a change - so often I find airlines run a bit late. Staff were all pleasant and helpful. Pilot's messages were pleasant, friendly and even a bit informative.

Cons: Web check-in ahead of time was a total disaster. I got an email telling me I could check in 36 hours early and "secure a good seat" but neither of the 2 sets of codes they provided in the email would work because it was all about Finnair but actually the flight was being run by British Airways. I spent about 30 minutes on the 'phone trying to get the appropriate sequence of numbers and letters to enter so as to check in and get a good seat - still nothing worked. This was at 5:45am - I regretted the time spent when I could have gone back to sleep. My daughter later spent a further 90 minutes trying to figure it out, only to be told finally that our only option was to get to the airport early and check n there which was what we did. It was beyond irksome. Please note, if the airline actually flying is different fro the booking airline, the locator number for check n will be DIFFERENT and needs to be provided to the customer to avoid a great deal of hassle and confusion. We gt particularly unlucky because BA computers had a glitch that day but the general point still stands.

Pros: The crew was helpful and polite, food was good

Cons: Would have preferred to watch one comedy movie. The crazy rich Asians was on a lighter side of a movie but I had seen that one already.

Pros: Staff

Cons: Same old movies Back row Seats didn’t go back

Cons: Icelandair has decided to make tickets cheap and baggage charges outrageous. My fault for not reading more carefully but I will not fly this airline again.

Pros: The plane and it’s crew were fantastic! The crew was totally customer oriented and provided great service for the entire flight.

Cons: It does no good to upgrade to Saga Class when you consider loading at Keflavik. A mob is herded on to a crowded bus and you wait at plane side with little room to move around. There is no priority boarding and the entire procedure might be acceptable in the Third World but certainly not in a country that has so much going for it.

Pros: Very helpful and courteous flight attendants; low fare; ability to reserve a seat when ticket was purchased. Leg room was good.

Cons: No procedure for boarding except to have everyone pile up in one mass.

Pros: Everything was wonderful. Staff was courteous, plane was great, food on the flight was exceptional. Compared to Icelandair, this was a dream!

Cons: N/A

Pros: Did not realize I purchased a “no checked bag” fare - and the $60 each way charge really pissed me off, along with the &48 charge to guarantee a window seat again, each way. The site was misleading, and I resent being peneluzed for trying to be efficient. A two week work trip needs to include a checked bag.

Cons: For a new plane, seats are very cramped. If you drop an earpiece on the floor, you pull a muscle to retrieve it / or make. Everyone in your row stand up. Decent movies mean a box under the seat cuts into legroom. A cramped, miserable 7 hours for this 6’0 tall American. Staff was as helpful as they could be, but my knees still hurt.

Pros: Over all good means.........., All well nothing to my dislike

Cons: Nothing to dislike

Pros: Crew was very professional, food options were excellent.

Cons: Icelandair has decided to make tickets cheap and baggage charges outrageous. My fault for not reading more carefully but I will not fly this airline again.

Pros: Service was great!

Cons: It would be nice to have a few more food choices for the long flight

Pros: Staff

Cons: Same old movies Back row Seats didn’t go back

Pros: Very pleasant and efficient crew

Cons: Departing 50 minutes late. However, most of the time was made up enroute

Cons: No leg room, flight attentend ignored me twice and I had to get up to get a answer from him.
