Find cheap flights from Los Angeles to London Heathrow

Pros: Seats were comfortable and the crew was great.

Cons: While the entertainment system had good options, the screen was very unresponsive when pushing the buttons. On average, it would take me over 10 tries to get any on screen button to work. Gave up several times.

Pros: Friendly crew, comfortable seats, good boarding process!

Pros: Awful food selection, small entertainment selection, none of the crew knew how to properly board the plane and left guests waiting in the aisle for over 45 minutes of standing for no reason and then yelled at the passengers that we were 'late' and that the standing passengers were causing the delay of the aircraft! The staff were VERY, VERY rude. I would do yourself a favor and NEVER fly Iberia!

Cons: Everything. They need an entirely new flight crew, new food service, new gate attendants, new baggage check, new ground crew. Just a joke.

Cons: Flight arrived late, didn’t land at the specified time. Loss the connection.

Pros: Keep it up with great services. !! Thank you!

Pros: Wonderful service from the crew, especially given that we were traveling with a toddler and an infant on such a long flight. Everything went smoothly.

Pros: nothing

Cons: the flight was delayed, boarding was the slowest ever and we received something to drink after 1,5h of flight

Pros: Of all the flights I checked this was the most convenient in timely manner and comfortable.

Cons: Movie options.

Pros: The crew did a good job dealing with so many customers and in one instance was able to resolve a minor conflict with seat way backs.

Cons: The seats should be fixed to prevent them from going back as far as they do. With space so small as it is, it is unnecessary to have them go back so far if at all. The food was poor, especially the cold egg and pepper sandwich at the end. My guess is that they were suppose to be heated which would have made them much better but the crew decided to give them out cold.

Cons: No food on board, very poor services but punctual

Pros: The most amazing service, good food and great steward

Pros: Punctuality Pleasant crew

Cons: No food on the flight! Due to some problems with the catering service, only a small sandwich was available.

Pros: Nothing

Pros: Departed and arrived on time

Cons: Stop the sardine can treatment of passangers

Pros: Flight was 2 hours late taking off. Completely ruined plans we had made for our first day in London

Pros: The flight attendants actually seemed to enjoy their jobs, they all were very nice and smiled not like other airlines where the attendants are very stiff and anything you ask for seemed to annoy them. Drinks sizes more generous than most airlines.

Cons: a long flight from lax to lhr needs more snacks and refreshments

Cons: They lost my bag and the flight was delayed.

Pros: Very helpful in getting on board luggage stowed, attractive interior

Cons: Scheduling was poor (turned up lighting far early than needed) and made too many and too loud of general announcements through the night for an overnight flight.

Cons: We booked row 2 to be a quick entry/exit but they board this plane from the rear. No entertainment, so bring your own

Cons: The infotainment system in my wife's seat 39J stopped working about half way through the flight.

Pros: Food was delicious. They served dinner and breakfast. The flight was not crowded. I was able to sleep by stretching across 3 economy seats in my row.

Cons: It would be better if the armrests went up.

Cons: My husband and I paid a combined $100 to reserve seats on our flight from LAX to London. When we got to check-in at LAX airport we did not get our reserved seats. Everything had been changed around. We did not even have seats next to each other. Upon complaining at arrival in London (there was no time at LAX to deal with this, as usual that airport was one chaotic mess) we were given a British Airways business card with a phone number that did not work/had been disconnected. I would like to get the $100 reservation fee back. Thank you.

Cons: My flight was cancelled, but after I took another flight, I was notified that my flight had merely been postponed for half an hour. By this time, I'd already missed my train in Frankfurt, creating hours of extra travel time and huge inconvenience after an already long trip from the US. British Airways said the cancellation had been due to weather, but skies were clear from London to Frankfurt. I'll never fly BA again.

Pros: the crew was accommodating

Cons: i was asked to pay to check in my luggage :(

Cons: Nothing

Pros: Keep it up with great services. !! Thank you!

Pros: Not a lot.

Cons: Our flight got delayed so American Airlines Auto switched us to a flight leaving a day later with a 17 hour layover. When I called to get it fixed I waited on hold for 30 minutes before I got through. Once we got on original flight they gave away seats we paid extra for and gave us no refund.

Pros: The flight attendants were the warmest and most personable I’ve seen in a long time. All ground staff had the same amazing hospitality.

Cons: Finnair A321 HEL-DXB, 6 hour flight, uses regular EuroBusiness seats (same seat as economy but blocked middle seat and better food), no wi fi , no tv, very uncomfortable aircraft.

Pros: I loved the flight it was o. Time the flight crew was great

Cons: Many people bring the own headphones these days, but I didn't and provided phones were so-so, volume on touch screen was jumpy too,

Cons: When booking through the third party and not paying extra to pick a specific seat - the flight was oversold and I was first to be kicked off. How can you take my money to confirm me on a flight but not ensure my ticket means I'm 100% guaranteed on the flight?! It was awful.

Between British Airways and Iberia, terrible handoff, communication and customer service.

Pros: The fare was super competitive and the service was top notch.

Cons: I was bumped off my flight and re-routed return to NYC.
