Find Cheap Flights from San Francisco to United Kingdom

I got a seat with more leg room and it was much more comfortable

Boarding was a bit frantic because of the lines at the airport for customs

No frills budget carrier, mostly exactly as I expected.

If you overbuy luggage allowance, there is no way to undo it, even within 24 hours. I made a mistake, thinking I needed to purchase more luggage, recognized my mistake right away, and still ended up paying for luggage allowance I didn't need.

Price was very inexpensive, crew was polite and efficient and our flights were on time. Airport in Iceland seems new and hip, but is small.

No entertainment, but that’s how they keep costs low. Seating was not incredibly clean.

In flight staff was friendly.

$46 for a carry on bag that I was not initially charged for on my flight from Cleveland. Bag had even less contents than when i came.

The wait

The screen didn’t change in time

Great leg room

I was next to an obese person who literally took half of my seat. That was extremely uncomfortable.

I was surprised by the amount of snacks and drinks on such a short flight.

The food was just ok.

Icelandair attitude suck and is the reason I will not even visit Iceland now.

the plane and crew

the chaos at KEV

Late flight. Both flights smelled of latrines. Charge for one checked back one way was 99.00. Flight attendant rude and said no vegetarian meals were available to purchase and I ordered within 10 mins of taking off. First she ignored me, even though she was talking to passenger next to me. I waited and she skipped right over me to next row. I had to press overhead light to get her attention. No veggie wrap available and I was told the vegetarian soup actually had chicken. No food is available otherwise on Iceland air flights. We almost missed our connection and flight crew didn’t even let us off plane before others who didn’t have tight connection. Husband was assigned a seat that didn’t exist on plane. Landing was the worst ever, came in on two wheels—all passengers were groaning. I travel a lot and will never choose Iceland air again.

The staff was nice and helpful

The flight was a little late and no free snacks or games on computer.

Flight was cancelled.

Boarding was confusing and disorganized

Nothing good to say about this flight. The plane was old with no entertainment. The sits where very compact and not comfortable at all. The food was a sweet bread and water. The flight attendants were rushing and will take a while if you needed anything. I felt like I was taking a bus with graffiti all over the place.

She was cheerful and genuine. I have dietary restrictions but was unable to preorder a meal. She went out of her way to find an available meal for me. I also saw her bring other passengers extra snacks and drinks.

Cramped seating.

The food wasn’t good and it would be great if they had pasta or some vegetarian option.

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

The configuration of the seats are really awkward. Seems very interesting at a glance, but not so nice when you have to sit in it for 10 hours. The business class seats are very narrow. I'm pretty petite so it was okay for me, but I think an average or bigger than average person would have a hard time turning at all while the seat is in lie flat position. I had a window seat which gives you more privacy as long as you have the divider up between you and the passenger next to you. You are really arm length away from each other though. And! You can't have the divider down the entire time because they serve your meals by passing it over to you across your neighbor through the divider. The divider is also required to be down during taxi, take off and landing. So, I'd imagine it to be very awkward if you're sitting next to a total stranger. You also have to straddle over someone's legs if you want to get out of your seat to the bathroom if you have window seats.

It was relatively inexpensive. I didn't mind the food/

This flight was operated by BA. Seats were incredibly uncomfortable. When the guy in front of me reclined his head was practically in my lap. TV's were crappy and the in-flight selection was mediocre. In flights announcements were very loud through headphones.

Nothing

We waited in the plane for 5 hours and ended with a cancelled flight. We were rebooked out of Oakland the next day. Missed an entire day in Rome for our honeymoon, lost a night at a hotel, and lost money on a tour.

The size of the plane

Leg space.

Arrival into Heathrow was unsatisfactory.

Wheelchair request was ignored

They lost our bags. Many of us on board. And they didn’t give us tracking numbers to follow-up. Argh

The way Thomas cook handled it.

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.

Even tough I forgot to request vegetarian meal they had extra ones available

There where no blankets and it was freezing cold

The flight to Manchester was canceled and I was not even informed until I got to the airport and was told I had no flight and I should rebook my flight with another airline. So my flight back to the USA NEVER happened because I refused to flight with Thomas Cook.

The flight was comfortable and the cabin crew attentive. The 7-hour flight time can't be beat. Free checked bag. On this occasion, the boarding in Reykjavik was through a jetway so you weren't exposed to the weather, though that's not always true.

Even using a jetway, boarding in Reykjavik is ridiculous, with inadequate seating and lots of standing around in confusing lines. They had four US/Canada flights leaving within 10 minutes, with the gates 10 feet apart and about 600 passengers jammed in four lines running through the concourse.

In flight staff was friendly.

NOTHING. My experience won't fit in the negative comments, so I'm starting it here. (1/4) We had a 21 hour layover in Iceland, so we left the airport for the night. The next morning, on our way to the airport, we tried to check-in online, but the online check-in service was not working. We arrived about two hours before our scheduled departure and had to wait in a long line since the online check-in service was not working. We checked our bags and ran into our first unfortunate encounter with the airport staff. He sent my friend's bags through, without checking the weight. When he weighed my bag, he then noticed that the first bag sent through was overweight, and mentioned that he had made a mistake. He decided to weigh both our bags together as one entity (to equal 88 lbs.) and made me empty out my suitcase of the extra weight from not only my single bag, but the extra weight from the first bag, as well. He said it was too late to retrieve the first bag, so my friend and I had to divvy up my stuff between our carry on bags. Had we known the first bag was overweight, we would have been able to easily taken stuff out of our OWN suitcases and into our OWN carry ons. Which would have been helpful for what was to come... We then walked through the foodcourt to buy some overpriced snacks for the plane. When we decided it was time to go to our gate, we passed a horrifically long line of people that we assumed couldn't be the line to get through customs, because the last few times we had been at this airport, there was always a maximum of 20 people in line. Once we realized that this line was for customs, we asked an employee working the line if we'd be able to make our flight on time if we had to wait in this line. He said not to worry, that we would be okay, because all of the airlines were notified of the unexpected delay at customs. We patiently waited in this line, and as soon as we were through, ran to our gates. At this point, we knew we were going to JUST miss the time for the gate to close, but were consoled by the fact that the employee at customs had told us that the airlines were notified that some of us would be late arriving due to the unexpected delay and line. We arrived at the gate, and the airport staff working the gate laughed in our faces and told us it was too late. They said they never heard from anyone about any delays at customs, and that the transportation bus to the airplane had left ten minutes ago. "Too bad!" they said. How could it have left ten minutes prior, if the gate said it had closed only a few minutes before we arrived? A lie. We asked about our luggage.

(2/4) They said that they would notify the plane, and the bags would be taken off, and that we could find them at baggage claim. So let me get this straight - the plane can wait for someone to sift through all of the baggage, find our bags, and remove them from the plane, but wouldn't allow us to take the probably less time to just get on the plane? We asked if there was anyone from WOW that we could speak to, and they pointed us in the direction of another gate. Once we got to that area, there was another group of people that also missed their flight due to the unexpected line at customs. They were speaking with a lady who was telling them that no one from WOW was at the airport, they all went home for the day. We also attempted to talk to this lady, but she was in a hurry to leave for the day, as well, and was very dismissive and talked to us in passing. On our way to baggage claim, we passed customs, which by this time, had no line. We spoke to three people that were standing in that area, and were looking for the guy who told us that our plane was notified of the delay. He was no longer around, but the staff standing there had said that they were unsure why we were told that any aircrafts were notified of delays because that was not true, and that they also were not even ALLOWED to tell travelers this information. So.... the guy that we spoke to in the customs line lied to my face, and was not even allowed to tell us what he did. This infuriates me for MANY reasons. If I had known that we would not make it through the customs line in time, I would have politely asked other travelers towards the front of the line if we could pass them. Most people are very nice, and would of course let us in front of them. I know I would have done that for someone. But instead, since a KEF AIRPORT STAFF told me that MY PLANE WAS NOTIFIED OF THE DELAY, I patiently waited in line. Yet another lie. We finally got to baggage claim, and spoke with one of the employees there. He told us that he was not aware of any bags coming back in, but it usually takes about 30 mins. At this point, it probably had already been that long, but my friend waited anyways. Meanwhile, I went back to the check-in area to see if there was anyone available to talk to about the circumstances, or if there was another flight we could get on because both my friend and I had to work the next day. There was no one anywhere, except for at the the Icelandair counter. The woman I spoke to there was very nice (shocker), but there was nothing she could do, that all of the flights leaving the airport to the US for the rest of the day had just closed their time for purchasing tickets. If we had not been lied to and if the staff had not been rude and pointing us in all different directions, I probably could have gotten us on a flight out that night. But yet again, we JUST missed the mark due to being misinformed and mistreated by the airport staff.

The planes are nice and new. Prices are very cheap. If you book economy and then upgrade to "extra room" seats and buy a meal seats you're basically flying in what they call businiess class for a lot less.

There was a huge snowstorm in Boston. A lot of people did not make it to the airport before the check-in desk closed. The airplane itself was grounded because of the snow for two hours. So a lot of people were in the main waiting area, while their plane was at the gate, but WOW did not care at all. They would not bring any gate agents out to check people in even though the plane was on the ground waiting. Many of us tried calling their support line - no answer. After a very long wait you get to what sounds like an India or Pakistan call center. The people there don't have any information, and the only things they can do are whatever you can do on the website. WOW has no real phone agents. I saw their gate agents later walking around and asked them to check us in - they shrugged. Would not check us in, despite the plane being on the ground. They could care less. Other airlines were shocked at how we were treated. Iceland Air was amazing. They saw our predicament and brought one of their managers out to their check-in gate to sell us last minute tickets on Iceland Air. A bunch of WOW customers ended up getting tickets on Iceland Air, and we actually ended up flying out of Boston before the delayed WOW air flight. If you get on the WOW flight - service is good. But you're taking a risk. Ground staff really does not care at all and will pretend they don't know you.

The price

The delay

Nothing

All the hidden charges. My good deal turned out to be worst deal EVER. I paid extra for my my seat and got bump from my seat to a middle seat. Icelandair attitude suck about the whole thing too and could careless too. After this I don't even want to go to Iceland or have the Kayak app on my phone. Kayak and Icelandair, will do everything to let everyone know how miserable you made my vacation.

Great planes. Great air crew. Great ground staff. Seats are large and comfortable. Crew does a great job of making sure you have what you need. Extremely attentive and professional. Gate agents are friendly and knowledgeable. They work hard to solve any problems you have - even if you're not and Iceland Air customer. I can't say enough good things about them. You can't go wrong flying Iceland Air.

the plane and crew

the chaos at KEV

No food goingacross

The transfer was too complicated, long distance to walk, security check line, not enough time for transfer, had to run to catch the next flight

The food wasn’t good and it would be great if they had pasta or some vegetarian option.

Flight was half empty, room to spread out

Having read horror stories online about booking with Kayak's partner Justfly, I was prepared for the worst (last-minute cancellations, partial refunds, all-around crummy service). Actually, my Finnair flight was great - it was operated by BA, so it was a nice new double-decker Airbus plane. It was maybe 3/4ths full, so I nearly had a row to myself - shoutout to the jerk who decided he was entitled to the aisle seat. The flight was smooth and easy and best of all, it cost a fraction of what the BA price for a one-way from SFO to LHR cost.

The food on BA continues to be meh, but what most people don't realize is that ALL airline food is meh, because your tastebuds don't work properly 30k feet in the air (it's a scientific fact).

She was cheerful and genuine. I have dietary restrictions but was unable to preorder a meal. She went out of her way to find an available meal for me. I also saw her bring other passengers extra snacks and drinks.

Cramped seating.

We were fed a nice pasta meal and offered drinks twice. They also gave a muffin for desert. The flight attendants were very nice and attentive with cheerful smiles. I wish every airline had service this good!

Everything is top notch for an airline company.

Nothing.... I enjoyed every moment of the flight.

Need better quality tvs for such a long flight and better movies There were only 4 Bollywood movies and not the latest ones either

Quick

Short flight

Flight attendant was not willing to go above and beyond as he stated he would. My husband asked for a coke and the flight attendant told him he could only get water.

The food was just ok.

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

Seats are surprisingly narrow, and lack privacy

The food, the staff and the free movie on the airplane.

My American partner's passport expires 2 months after our return to the US. Unfortunately, the French issued a year ago the following rule: to enter France, the foreign passport must not expire at least 3 months after the return date. British Airways let us fly to London, explaining this to us, how it would be on us if there were problems further down, and that we would have to get our luggage in London. We chose to fly thinking it would be OK, we had listened to an online person who had had the same problem and the French later told him they would have let him in, also I am myself a dual citizen of France and the US, plus I am autistic, an invisible disability (in my case) that makes it impossible for me to travel alone. I usually do not even say it since not much is understood -by those who do not have it- on how to accommodate it However in London BA did not allow my partner to go on. Due to the fact yesterday was Easter Monday, the American consulate in London was closed. We have spent the night in a nearby motel and now, the next day, I am waiting alone back at the airport with our 2 large suitcases while my partner is at the American consulate. We are poor, do not have phone, currency or charger for England, and I do not do well with stress, so it is difficult. Now we cannot easily reach one another. We hope to be able to fly on a standby basis (that's what BA told us we could hopefully do) later today. Sorry for this long letter, I hope it does not bore whoever reads it (if it is even read :). Anne-Laure

Crew were delightful! Amenities perfect.

Very little space between seats.

Waitied.. in the okanevdir 40 minutes! Because couldn’t get the jolly to work for the steps Had to walk steps with my elderly mother with our carry on in the pouring rain.. then miss our flight to Milan had to wait 3 hours for the next flight ... which was also delayed.

wonderful crew, good enough food, wide entertainment, seats as good as can be expected, great plane, great flight, great crew, on time and safe and arrived in good spitrits

as always, rather crowded, seats rather tight,

Nice newish planes. Competent but basic service in the air. Nice air crew.

Ground agents are bad. Don't care about you. Won't answer questions. Don't care what happens to you. Don't care if you make your flight, or if your connection is delayed. There is no phone support. If you have a problem - you're on your own. Online checkin is broken. Does not work at all.

Price was very inexpensive, crew was polite and efficient and our flights were on time. Airport in Iceland seems new and hip, but is small.

No entertainment, but that’s how they keep costs low. Seating was not incredibly clean.

Stewards were upbeat

This is one of the best airlines I've ever flown. Very nice comfortable planes. Excellent air crew. Everything they do is at a high standard. What really sets them apart is the really great service. I had a problem with WOW air not honoring my ticket due to snow. I had to book at the airport on Iceland air last minute. They didn't have a gate agent who could sell me a ticket - so they sent a manager out from the back office to book us so we would not be stranded due to WOW's incompetence. Booked us just minutes before take off, escorted us through security and onto the plane. Start to finish less than 30 minutes. Amazing service. Their class of service is far above that of major carriers. Iceland Air works harder and makes sure everything is right.
