Top tips for finding a cheap flight from London to San Francisco

  • London Heathrow (LHR) is one of the busiest airports in the world, so make sure to check your terminal in advance as distances between the terminals can be long if you make a mistake, and the journey between them can take more time than you think.
  • Download the London Heathrow app onto your telephone before you leave, as this will update you in real-time on delays, and also help you easily navigate the terminals to find restaurants, services and your boarding gate.
  • If you are pushed for time but very hungry, look out for the 15-minute symbol at many of the eateries at Heathrow Airport; these places will take your order and deliver your food within 15min.
  • If you find yourself with lots of time to spare before your flight, head to the Number 1 Lounge in Terminal 3 after security – as well as food, newspapers and drink, it also has a travel spa and sleep pods that can be reserved by the hour.
  • When planning your flight into San Francisco SFO Airport, remember that because it’s so close to the coast, it is prone to being foggy, which means that landing and take-off capacity becomes frequently limited. Make sure you factor in some extra landing time in your arrival schedule for unforeseen weather delays; it’s all part of the wonder of arriving in the area.

Cabin crew on our flight showed lack of any customer service gruff and acting annoyed if you asked anything and I mean anything Example a man on the seat over dropped his beer on my husbands blanket We asked if we could switch out blankets cabin crew Said. No we don’t have any extras OK well can you take the wet one Cabin crew looked disgusted and annoyed Took it no OK or yes just a growl

Quick flight. But cabin crew were very noisy and talking too much, especially when we were seated at the back of the plane trying to sleep through the night .

My ticket was for Premium Economy and all the seats were taken, I was placed in Economy class and I’m looking for a refund.

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

The delay was an issue. Other than that. Every thing good

Hi vergin Atlantic service was good but the flight ticket agent travel up charge me extra 57 pounds as a airport charges, actually I refuse to pay but they say if I not pay £57 then they say you will not be able to travel from Heathrow to goa ,so for me there was no option and it was just 3 day before my departure so i paid, so please look in to the matter. And I have a receipt of £ 57 as well .thanks

Staff didn’t check cabin well for landing seemed more interested in chatting to each other. Food was poor and differed from pre order.

We were in the last group to be called to the flight - which was 30 minutes late taking off. While we were lucky enough to have been given bulkhead seats (due to a medical condition I’d told them about beforehand) the seats weren’t particularly comfortable. A crying baby for the whole trip made things worse, so the crew managed very well with coping. The final thing I’d say was that there wasn’t enough food served during the flight.

Very good. Glad we had Premium for the flight out.

We flew Upper Class from London to The Turks and Caicos. Check in was amazing. Our ldriver too us directly to a special entrance to terminal 3. It took 10 minutes to check in and clear customs. Amazing! The VA lounge is large and comfortable. Boarding the flight was easy and without a wait. The crew was excellent. But the seats were awful, strange and uncomfortable. Having a comfortable flat bed seat is the reason we pays 1000s extra. The VA 787 uses a reverse herringbone configuration. Look it up. You have your back to the window and are facing the aisle with no privacy. Turning the seat into a bed requires assistance from the crew so not very spontaneous. . The food was ok. A bit tasteless and meager portions. Had to pay for WiFi. I believe VA has other configuration on their dream airbus flights. Lots of stuff about all this on YouTube where you can see what I have been describing. I can not recommend taking VA on a long flight with these seats.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

So so. Terrible aircraft choice for that leg of the flight.

Our seat tv didn’t work All the rest was perfect

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

Meals were adequate but could be better. Lots of movies, podcasts, tv shows. We really enjoyed using our personal headsets highly recommended. 15 hrs flight great to travel at night.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

the plane was old. the wifi didn’t work. the entertainment was boring and dated. the charging ports were impossible to find. i was mostly ignored by flight attendants that had no problem speaking to the man beside me. i got two drinks the entire time i was on the plane.

Quit making seats narrower and narrower. The guy beside me spilled over in to my seat.

The service was non existent . Crew did very little didn’t even answer call button . Premium economy in this long haul was the worst I have ever experienced . Never again flying with them .

The crews are great.. Easy boarding. Inflight entertainment ok. Food is a disappointment.
