Insights shared by verified travellers who flew the route from Heathrow to Fremont 
Verified travelerFlew with American AirlinesLHR-SFOMar 2024
Heathrow is vast, allow plenty of time to drop bags and go through security. At San Francisco the immigration takes a bit of time and we had to wait around 1.5hrs, bare this in mind when booking car rental. The is a shuttle train from the airport to the car rental area which is very slick and efficient.

In London triple check your flight they have multiple leaving for the same destination once - it is easy to get them confused

Friendly staff, always good food , as comfortable as it can be in economy

Business class is not worth it. Not comfortable and old plane with no privacy or enough space unless you on the single seats

We didn’t fly into Neuark , because it departed without us . We ran to a closed gate , and no staff to assist, then to a customer service center that was also closed, then briskly walked (20mins) to another customer center and got a ticket , waited 2 hours , got a flight to JFK instead, because of the time delay we Ran to catch our train home , and again our luggage arrived 3 days later delivery time at 3:45 in the MORNING!!!! Crazy!!!!!! Took a few days to shake off this disappointment of your service. You’re an embarrassment to customer service .

A bellow average experience. A delayed flight , no staff to assist , running and panic to connecting flight , 2 hour wait for customer service. No luggage when we arrived , luggage delivered 3 days after at 3:45 AM !!!! Much stress and anxiety from this experience. Please repair your Brand .

My luggage was lost and I did not receive any compensation

Pleasant up to Vienna. Afterward (Vienna- Zagreb) was an horrific experience

Leg room and seat back not a good recline (middle seat)

The option to check in the carry on bag for free was very convenient. If one checked bag could be included in the ticket price that would be even better.

It was very good, ,especially the working people in the plane, they are so polite.,thank you

I paid for carry-on bag, but they did not let me take it on board, persuaded to check it in because the flight was full. I agreed to help them out, and they mixed up tag numbers and my bag got lost. I had very valuable things in there, and my whole vacation experience was ruined. I even asked the boarding assistant why the tag number was different from the assigned one, but they assured me it was alright and the bag will arrive to my destination. Nothing arrived of course. Incompetence of boarding assistants cost me the loss of all my things.

My only complaint is that the pocket in front of me was ripped and my things, like iPad and airline magazines, kept slipping to the floor.

Flight delayed yet again. Crew apathetic and unhelpful re affect on connecting flight.

I think Virgin is one of the best flying experiences, especially from/to the UK. The staff are so helpful and fun, the food is good, seats comfortable, goof entertainment and great value. Check in and boarding is pretty pain free. I also find that the other passengers are generally so kind and considerate than when I've flown other airlines.

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.

This was a 5 hour flight with no entertainment and with a snack being provided (pretzels and fruit bar), which are both high in carbs and sugar. Nuts would have been a better choice.

The seat seemed roomy, the service was good, everything was fine.

Was realllly smooth. It was delayed but we were well informed.

Connection coordination with Star Alliance partner could be better. Lots of check in setup was not interlinked between operators.

The senior flight attendants were amazing. Totally different vibe from other carriers. Easy 10 hour flight in Business Class. Great food. Good humor as well.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

I was lucky to sit in a seat with legroom in economy . The airplane felt like it was 100 years old, seats were very basic, barely reclined. Food was alright , staff was ok but not the friendliest. But all in all ok trip, perfectly on time

Haven’t used United in a while. Was surprised with the free blanket and earphones. Service was great. Huge plane. 9/.row.

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

The width of the chair is very small. Not comfortable at all.

Great crew dealing with the most unprepared family with a million kids and zero sense.

We were disappointed not to be able to buy out preferred seat from date of my original booking, which was about 40 days before the trip. When we arrived in Hannover on the Oct 10 I tried every day and the weed site said I have to wait until ck in, did that and still was not able to. Get to the airport and out seats were separate from each other. The crew was able to get seats together, was not the most comfortable. Don’t understand why this happened.

Actual flight was smooth but we were delayed 70 minutes. Were promised to make it up to us but were given no refreshments

I had handicap and pre board due to a recent broken arm, was made to find my own help placing carry on baggage in the storage above. My tv and entertainment unit did not work correctly, requested help and it took 30 minutes to get help, she did not fix it or come back to see if it was fixed. I went to her a second time and she did another reset, still did not fix.

Did not fly HOU to SAT as flight was cancelled.

The plane was clean and the staff courteous and professional. The seat bottom was uncomfortable but only after many hours. It had a pressure point that left me a small bruise on my right leg (very surprising). The pasta was terrible (hard on the edges sticking out and soggy on the bottom edges) but I guess that's how it comes out in a microwave (?). The entertainment was glitching and shutting off every 20 minutes or so but, in the end, we made it home safely with very little turbulence and that's what really matters.

The food was straight up bad not gonna lie, seats are uncomfortable so I had to re-adjust my self most of the time, delayed our arrival time by alot.

It was excellent. I upgraded from premium economy to business and it was totally worth it. We were on a 747 and I sat upstairs and enjoyed the privacy. The crew was incredible especially the woman who had been working with you all for 30 years.she was absolutely spectacular as was her cabin. The food was delicious. I would just serve bread with the meal. Don’t take it away!

The connection to LYON was very tight. The flight was nearly finished boarding when we got to the gate

I did not like that they failed to put my luggage on my connecting flight to Athens. I was promised it would be located and delivered within 2 days but later told there was no information on its location. This caused me to have unplanned for expenses because I then had to purchase new clothing to wear on my vacation. I did not receive my luggage until my return flight home. I will not be traveling with them again.

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

They had about 20-25 people overbooked. Including me. Why is this?? I was put on a flight to NC an hour later with a 4 hour layover. I was supposed to be home at 1045am instead i was home at 7:30pm. An extra day to pay for dog care.

Boarding is not controlled as groups called was not enforced

Horrible food and uncomfortable plane. One toilet was out of service.

Business class is fantastic! Lie flat seats, great meals, privacy, and lots of nice amenities!

Flight to Seattle was fine. We were delayed getting into our gate. The connection time was short and they make you go through security again which was slow.

The crew was great, the food was great, the seats were torture. I just could not get comfortable. Too narrow, too close to the seat in front. I felt guilty about reclining my seat and resisted but the people in front of me did not feel the same way. I thought both coming and going that the discomfort would conceivably be enough to prevent me from going abroad in the future. Will it? I'm not sure - but it will definitely be a factor in my choice of travel.

Food was pretty good and crew did ok. Boarding was a disaster. Seats and leg room were not conducive to a comfortable flight, especially if you are 6’3” and have the person in front of you leaning their chair all the way back for 9 hours and your are told they are allowed to do that.
