Find Cheap Flights from Boston to London Heathrow (BOS - LHR)

Cons: It could have left on time or they could have told us they weren’t leaving and let us get some sleep.

Cons: Seat assignment with Economy ticket.

Pros: The crew was extremely rude. They did not come to collect trash and so all passengers were left holding their coffee/ tea: beverages during bumpy landing.

Cons: Attendants were rude. I didnt understand why. Also, I purchased a window seat but there was no window in my row. I spent the majority of the flight feeling ill.

Pros: Nice to have more room in the premium economy section.

Cons: Not even a smile from the crew and no help when asked. I don't expect Asian-style grace and class from an American airline, but I do expect good old-fashioned American friendliness, and there wasn't even that. Also hate the all-darkened cabin in the daytime.

Pros: The crew were lovely and the seats were ok.

Cons: Not a lot to Improve on to Be fair

Cons: More leg room

Pros: As usual, punctual flight with friendly crew.

Cons: Pity the wifi in international flights isn't complementary (or at least a basic connection like on domestic flights).

Pros: crew was nice

Cons: First time flying with a partner through Delta, so they stuck us on a Virgin Atlantic flight meaning I didn't get my free Delta check in bag (a fee of $60 each way) when I have gotten it every other flight I have ever taken with them. It was also 2 whole hours late in boarding.

Pros: The crew is really welcoming

Cons: The seats are too narrow and a bit too hard

Pros: Like the overall KLM experience

Cons: Food could have had better quality and the stewardess served it all at once versus in the various courses.

Pros: The crew are amazing! Attentive and friendly.

Cons: The seats could have been bigger.

Cons: Flight 2 hours delayed, started boarding but had to wait on line 10 more minutes on boarding ramp for plane door to be opened, upon landing in Dublin had to wait on tarmac for anther 15 minutes for stairs to arrive and be connected to airplane. Then had to wait another hour for checked luggage....

Cons: It was great

Pros: Delta is wonderful! Helpful and on time.

Cons: Seat assignment with Economy ticket.

Pros: The crew was extremely rude. They did not come to collect trash and so all passengers were left holding their coffee/ tea: beverages during bumpy landing.

Cons: Attendants were rude. I didnt understand why. Also, I purchased a window seat but there was no window in my row. I spent the majority of the flight feeling ill.

Pros: Service is awesome. Food is great.

Cons: The air conditioners fan was bad and they had to fix it in London which took over 40 minutes off travel time...we arrived much later than expected in Lagos

Cons: Flight 2 hours delayed, started boarding but had to wait on line 10 more minutes on boarding ramp for plane door to be opened, upon landing in Dublin had to wait on tarmac for anther 15 minutes for stairs to arrive and be connected to airplane. Then had to wait another hour for checked luggage....

Cons: This was actually a Delta flight (code sharing). The airplane was very dirty and the seats were uncomfortably small. I am 5'3" petite lady so I can't imagine how terrible the flight must have been for others. The meal was awful but I don't expect anything these days.

Pros: A safe crossing over the Atlantic!

Cons: I queued at the Virgin Atlantic departure desk only to be told I had to walk to another terminal (the farthest one away) to queue for Delta Airlines. There was no mention of this on my e-ticket. Had I been elderly or unwell I would have been very upset. Delta is really the poor relation and does not even begin to compare to the journey I had to Boston on Virgin which was fantastic. Very disappointing but I was delighted to get to Heathrow safely.

Cons: Unfortunately because the flight was delayed 2 times I was going to going to miss my connect flight to London. So I canceled my trip. I would appreciate a refund as I don’t understand what all the delays were about

Pros: I like the professional approach of the airline and the staff. Seats are really comfortable and i did not need my sleeping pillow at all as the headrest of my seat was already so comfortable.

Cons: There is not much which i did not like about this airline. Just like other airlines, now have started feeling that Economy class travellers are being approached with bit biased approach in hospitality though they have major contribution in meeting flight running expenses. All airlines should start considering this fact and improve the overall approach.

Pros: Good beverage service.

Cons: Over an hour delayj for departure.

Cons: We were allowed to choose our seats from SFO to Amsterdam but not for the return flight. I like to be able to choise my seats when I book the flight. Choosing seats 24 hours before is not convenient when traveling for the return trip.

Pros: Like the overall KLM experience

Cons: Food could have had better quality and the stewardess served it all at once versus in the various courses.

Cons: This return flight was much better than the flight going to Amsterdam. I believe the biggest factor was the type of aircraft. The old 747 just didn't meet expectations. The newer 777 on the way back was much more comfortable, with better amenities.

Cons: Screen did not work and dinner wasn’t provided on the way back from Iceland.
