Flights from London to Boston: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew the route from London to Boston 
ShawnFlew with British AirwaysLHR-BOSDec 2024
Know that gates are posted just about an hour before takeoff and it takes a bit of time to actually get to the gate. If you make a mistake there is no train back- you have to walk to the correct area and that are at least 10 minutes apart. Make sure to have ALL liquids ready to place in the tray at TSA
JaiFlew with British AirwaysLHR-BOSJan 2025
The boarding area was a bit crowded. The restaurants are serviceable, but not great.

If you are arriving on a late flight check in to an airport hotel at Logan. Good choice, easy access and good start to your trip
Verified travelerFlew with British AirwaysLHR-BOSMar 2024

RandyFlew with British AirwaysLHR-BOSMay 2024
Be aware that the cost for your luggage has gone up to $75!!
StephenFlew with British AirwaysLHR-BOSJan 2024
My best tip is make a ton of money, so you can afford to fly business or first class.
Verified travelerFlew with FinnairLHR-BOSDec 2023
If you’re looking for a hassle free and good customer experience, avoid BA; Fly American. As soon as you board the plane, set your watch to local US time to help adjust to the time difference.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Any flight that lands safely is a good flight. However our leg from Helsinki was delayed 1 hour with no explanation. The delay would not allow us to make our connection to Cincinnati. I was informed by American Airlines that our Cincinnati flight was rescheduled for the following day. I immediately made a non refundable hotel reservation in Dallas. Upon exiting the plane at Dallas I was given a hotel voucher. Nice, but I can't get a refund on the hotel I booked. A little communication would have been helpful. Food on Finnair is below quality of Korean Air.

The cabin crew really looked like they wanted to be somewhere else. They weren't really interested in providing an attentive service to full fare paying passengers at all. However the Captiain's in flight announcements were relaxed and very entertaining.

Crew were professional and responsive. Food was mediocre and breakfast could do with revampinmg

Food was very ordinary for premium economy, very small portions.

i dont know WHY they call it business class. the seats are NOT significantly wider than economy seats, they just do not let the middle seats be beepked to give the illusion of more space between passengers. the seats do NOT recline any more than economy seats either. the only real difference is the full meal served to business (vs none for economy). I would rather have a wider, lie flat ACTUAL business class seat with no food for a 3 hr flight. this was pretty disappointing to say the least.

There wore nice leather like sits, in my opinion seats lay out bit tight . Crew was great they did averything possible to make averywone comfortable as possible, food was, think worst I ever head on flight, head chicken and yellow rice. Ice cream was a nic treat.

Our previous flight was delayed but they waited for us to board.

Flight was delayed, short time connection to next flight but we make it, service was good, worth to fly just to try thair on board blueberry juce. Eccelent communication with airline.

My American Airlines flight was deleted and you guys never let me know

Flight took off an hour late. Had to stay on the tarmac for half an hour after landing. Both annoying.

We had an unfortunate experience where we had to leave the aircraft after boarding, shortly before the scheduled takeoff time, and re-board. The reason given was that a passenger felt ill and had to cancel their plans and therefor their luggage had to be found and removed.

We’ve used VA before many times the experience is always been good they have lovely staff and the food is always delicious.

Everything about the flight was amazing from check in to boarding entertainment was okay food we didn’t try.

Seats were old and dirty, for a long haul flight you expect to be able to recline and for the av to work properly. Choice for vegans was fruit….

The Virgin Atlantic crew was very good. However, the equipment was OK, the seats were OK, but her bags did not arrive with me. Two bags showed up a day later and I’m still waiting for my third back.

The crew was very good. However, the equipment was a bit dated. Some of the electronics were not working. To top it, three bags didn’t arrive with me. Two of them were delivered a day later. I’m still waiting for the third bag, I was so looking forward to this virgin Atlantic flight, but, I am disappointed.

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.

It would have been better to have USB charging ports available on the longer haul Flight that one of 2 hours

Was very good Staff was great. No tv monitors tho. So long flights make it longer

The worst. No free beverages. No entertainment on an overseas flight. Not enough space. Never again.

Play is affordable! Only way we fly from the states to Europe. Left late but arrived on time

have screens on backs of chairs...offer free snacks and water

Boarding and crew was great. Flight was cold, need layers. Deplaning was hard. We had to take stairs off the plane and I was separated from my travel companion because we were not seated together and they would not let him wait for me to get off so we were forced onto different shuttles.

Check in and boarding was easy, crew was cheerful. Not much to read or do on the plane and our neighboring passengers were talking loudly so we could not sleep. But overall good. Great coffee.

Flyplay is the only way I travel to Europe. Had a 15 hr layover in Iceland. Normally this would suck, but I regret a car and saw the black sand beaches, several waterfalls and sky lagoon. And finished with lamb at cafe Loki.

did not get the seats we had specially paid for

This is a no frills airline. You cant expect much for the price. Low cost flight, clean, nice staff. That's all I need for the price. If you want more, book with another airline and pay more. For Europe trips, PLAY is the ONLY airline I use

No food was served for 7.5 hrs flight. When our flight changed to other airlines due to wether issue, our seats booked with no checked in luggage when I already payed for. We end up to pay 90 euro per suitcase.

Booked with Kayak… Economy Class it said. I had filtered for 1 checked bag. Get to boarding and it says I have Economy Light w/ no checked bags. $136 each way for baggage now. Do not use smartfares.com. Very misleading and a terrible start to this trip.

Our three ski bags did not arrive and are still not delivered, one full day later. With one ski bag not traceable at all. I would not fly Iceland Air again.

Horrible. The flight was delayed by over 3 hours but updates were barely provided. Boarding started 3 hours late then stopped because their system crashed. So now, passengers were standing for 15 minutes in the open waiting to get boarding passes scanned and get on a bus. Duty-free closed around 4-4:30. Only 1 food outlet was open and it was super slow and busy since it was serving passengers from multiple flights. So a number of passengers couldn't buy meals at the terminal. Since the flight was delayed by over 3 hours, we could have been offered snacks on-board. Nothing. The seats barely reclined. In-flight entertainment options were pitiful. Overall, a miserable experience. Never flying on Icelandair ever again. :(

Bad. Flights were late, by hours. No clear information was provided even until the delayed boarding time.

Again, lines for boarding are a problem in iceland. The flight itself was fine and very smooth. No complaints. We would definitely fly icelandair again.

take snacks and food. purchase options in flight are not great

Had a screaming child next to us. Not the airline’s fault but still annoying.

Highly disorganized company, poor customer service. Packed seats on a 737 for a trans-atlantic 9 hour flight. Greedy company policies, no meal or snack provided for 9 hour flight.

Never took flight. See previous comment on trip from Boston to Reykjavik. Used a different airline that i had to find and book.

They did not provide free WiFi, It could be purchased for, I think, around $25, This seemed excessive.

Less than average, low level of shared required information needed during the transfer from airport to another, also the used team during boarding In Indianapolis station is Not Professional

Reliable, great value, but not outstanding in any aspect. This is similar to the experience you get in most international carriers like Etihad or Delta.

Flight got diverted because of an emergency and the crew were fantastic and probably saved that passenger’s life. While in emergency landing some measures could have been taken to prevent additional delays. In general not great experience with BA. I used to fly BA years ago all the time, very disappointed by the whole experience, seats were tight, bathrooms tight.

Business class area too small and chair and equipment not comfortable .

Lost my luggage in London Was double charged for luggage

Boarding could have been better organized. The one member of staff disappeared for a while so boarding by group relied on honesty.

I never made this flight but the staff helped to get me rebooked (see previous review)

The seat was very uncomfortable. It helped to use the foot rest. Could not sleep because of the seat.

The seats are incredibly uncomfortable. My luggage didn't make it on the flight from London to Nashville.
