Flights from Europe to Boston: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Europe to Boston 
Verified travelerFlew with British AirwaysLHR-BOSMar 2025
Try to get an aisle seat and walk around the plane as often as possible. Your legs will thank you
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
HFlew with Azores AirlinesPDL-BOSDec 2024
Expect to walk up the stairs on the plane as the ponta drlgado has no air bridge
SheenaLIS-BOSJun 2024
Be easy for the longer lines for passports and going through customs. Give your self plenty of time.
ErikFlew with VuelingBCN-BOSJul 2024
Check in online if you must fly this airline. Avoid excess weight (up to $250 per bag!). Better yet - fly another carrier. Single worst flying experience of my life. And I easily fly 150,000 miles every year with all types of carriers.
Verified travelerFlew with British AirwaysLHR-BOSMar 2024
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
BridgetFlew with ITA AirwaysFCO-BOSApr 2024
Rome is an excellent airport. If connecting through Rome, know that there is a customs station you need to go through before your gate.
HeidiFlew with LufthansaMUC-BOSMay 2024
If you’re changing planes in Munich leave more than 1.5 hours between flights. Our first flight was late so we had to rush to next and it was quite a distance plus you have to go through passport security again.
CassidyFlew with IberiaBCN-BOSMay 2024
Check to make sure the airline you are booking through is not subcontracting it out to a janky airline to cut costs.
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.

I like for how they process during check in. It was very smoothly.

10.0 ExcellentAbdulla, Jun 2025CMH - JFK

I like for how they process during check in. It was very smoothly.

The flight was scheduled for 2:30 PM. Early in the morning we got a text message saying the flight was delayed and rescheduled for 3:00 PM. We got to the airport with that in mind. Then we got a message during check-in at the flight was rescheduled again for 2:30 PM. We almost missed our flight. In fact, our bags Were told that they would not make it. At the end, everything worked out. But it is very stressful.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Excellent check-in. Crew was good. Excellent communication from flight deck.

Great overall. There was a bit of turbulence so they could only serve water because too much turbulence for the carts. Was glad they prioritized safety though

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

The service was great. However the lounge only gets passing grade

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

You should not have to pay for WiFi in business class

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

I would definitely use a Linus again, the price was right, the service is excellent. No delays. Wish I had a direct flight from my hometown Detroit.

At check-in the unmanned machines said QR code was invalid so had to queue for over an hour to check in bags

There was no room in the seats, smallest room we've ever had and the food was awful.

i used to fly aer Lingus regularly but due to price - poor seating etc i have been using other carriers - i now have aer lingus in my state and the price is always the highest - i have flown to Ireland 11 times in last 24 months and have not used Hartford because of price

Nicest staff I’ve experienced on a plane! Good food, great entertainment, and they gave out little blankets that my kids loved. All in all, great experience.

This flight was of exactly the same high standard as the outbound leg, exactly a week earlier - except that we didn't have any food or drink because it departed at around midnight.

The Glasgow to Dublin route was very efficiently boarded, flight and landing and disembarkation were all super smooth. Dublin to JFK flight I was very pleasantly surprised overall. This was my first time on Aer Lingus and having already come off the short regional flight I was curious to know how the international flight would go. Aircraft was solid, entertainment options were better than expected, flight crew were experienced and operated like clockwork. Main entree left a little something to be desired but the snack was very tasty. Boarding and disembarkation again very smooth and pilots got us in earlier than expected. Would definitely fly again

Unfortunately the flight was delayed for 50 min. Just as we were about to board so that was a drag. The boarding was average. The bag check in process was new to us and efficient. And the flight itself was smooth- basically no turbulence.

I liked how they looked after couples by providing a row of 4 seats if available.

It was ok not that much because I always travel with Emirates airlines, Etihad, airlines, Qatar airlines compare to them food and comfortable was too low . Staff was good . Helpful

Cheapest airlines I have ever been on. I got downgraded and never got on united. I got rerouted through Vancouver onto jetwesf

Never happened. Flight was delayed. Had to be re rojyed

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.

Beautifully maintained airplane, good food, professional crew, top-notch communication. I highly recommend Lufthansa for intercontinental flights between the United States and Europe.

Lufthansa is my favorite airline and have flown oversea with them for the past 25 years: i always found them so professional and incredibly efficient from checking in to arrival. I also love their Munich or Frankfurt airports.

The United flight was excellent! The flight attendants were attentive and nice, and the food was very good! And the glasses are larger than on Lufthansa flights! I don’t want to have to ask for 15 glasses of water because their glasses are ridiculously small!

The food not that great. Did not like the fact that we could not purchase upgrade at the airport

We paid for business class, and my seat did not work at all. Each time I wanted to adjust the position, an attendant had to come to physically force the seat into its new position. They tried to fix it by fiddling with the electronics (military reset, for example), to no avail. Also, the food was just mediocre. We were at the end of a serving section, so they ran out of several choices. (This was on the flight from Los Angeles to Munich.)

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

The plane was very clean. The bathroom was clean as well. The land crew were very polite and informative and helpful. They informed me that there is a long way and challenging to go from international terminal to national terminal and in addition to getting my suitcases and going through customs and dropping them again for my second leg of trip which was San Francisco to Los Angeles . I have left knee issue and had a recent fall with aching muscles all over, the land crew suggested wheelchair help for me, God bless her. If I did not have help, I could not make it to my last terminal. Thank you UNITED AIRLINE!

Better synchronizing the boarding processes. The audio announcements, the personnel and the digital signage were not saying the same thing. All confusion.

The first class seats were unusable, mine at the end of the flight, my husband's in the middle of the flight, and the one next to me was unusable either, they had to move the person to another seat.

Last minute gate change. Didn’t put our TSA global on our trip even though we asked multiple times to confirm. Did not help with food when could not eat what was served.

Our luggage didn’t arrive with us, that puts a damper on the whole trip.

The cabin was bit colder than I like but the crew members looked after us very well. They did even offer hot water bottle and hot chocolate. I cannot rate the crew enough excellent is not good enough. They really were wonderful.

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

This flight from London to Chicago was actually on an AA airline. I did book through BA but the flight was AA. Great flight, hectic in Chicago, I wouldn't choose to fly through Chicago again, but that's not the airlines fault. The flight itself was great.

Push back is not working when I complaint a male staff he told me that most of the seats are like that so we can’t do anything

Seats were way too small. I got claustrophobic waiting for trash from meal to be taken away. I couldn't move to even close my tray until trash was taken.

Was 3 hrs delayed and my poor friend I met in Barcelona was waiting at airport for 3 hrs. Dallas airport was awful
