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

Insights shared by verified travelers who flew the route from Boston to Europe 
Verified travelerFlew with Aer LingusBOS-DUBJul 2025
Whatever airline you choose, spring for a class with more leg and overall body room than economy (or whatever the cheapest class is called).
PatrickFlew with DeltaBOS-AMSJun 2025
Be prepared for a very confusing time in Schipol airport where directional signage is not helpful. In one visit our group had to be escorted to the particular carrier’s desk as we were told we’d not be able to find it ourselves.
Verified travelerFlew with Scandinavian AirlinesBOS-CPHSep 2024
Check with the airline and validate that all of the advertised benefits are indeed available. Paying higher price for the Economy Plus tickets may not be worth it for you as a number of advertised benefits are not available, definitely not in Boston
YvetteFlew with SWISSBOS-ZRHNov 2024
You pay for everything on Swiss air. The airport in Zurich is large, so does not leave a lot of time to get between gates if your flight is in another terminal.
BradFlew with IberiaBOS-MADOct 2024
Make sure to book your own seats and don’t leave it up to someone else. We were supposed to have window and aisle seats and did not. We had to sit in the middle of the plane which is cramped and difficult to move let alone eat.
JonFlew with Scandinavian AirlinesBOS-CPHJun 2024
Be prepared for a possibly short layover between flights. Mine was only 45 minutes and needed most of that time to clear passport control and get across the airport. That said - it seemed that the SAS crews were used to that. On the plus side there was no waiting in the terminal.
Verified travelerFlew with IberiaBOS-MADJul 2024
Good luck- have your phone charged and your confirmation number handy
BarbaraFlew with Aer LingusBOS-DUBMay 2024
Pack what you need in a carryon since it is likely you'll arrive without luggage.
MaximFlew with TAP AIR PORTUGALBOS-LISMar 2024
I was waiting for a flight boarding announcement in the Lounge in terminal C at Logan Airport in Boston, but the announcement never came. If I did not go to the gate to check, I might have missed the flight. So, do not count on the airline to communicate flight boarding information to the lounge staff. They are supposed to do that, but, apparently, sometimes it does not happen.
Verified travelerFlew with British AirwaysBOS-LHRJan 2024
Leave plenty of time if connecting in London as most connecting flights are in a different terminal which requires a bus or tram ride. Also if you’re not at the gate 30 minutes ahead they will not let you on the plane. Apparently this is a Heathrow not airline rule.

Did not know my son and I had different seating arrangements. He was fine, but it was disappointing.

4.0 OkayAnonymous, Jul 2025ATL - ROC

Did not know my son and I had different seating arrangements. He was fine, but it was disappointing.

Flight was canceled, and no effort was made to help with rebooking, no hotel vouchers, no car transportation and minimal food voucher and most places for food were closed by the time the voucher was given. Waited for 3 hours for bags. Simply the worst travel experience I have ever had

Food was surprisingly good but the WiFi was not great

this crew didn't care much. bumping carts into seats more times than i care to remember

Very late arrival at PWM. Late jet getting to ATL. Equipment problem with aircraft - could not get enough water onto plane., Another delay getting FAA approval for flight with bottled H2O. Not the crew’s problem.

Everything was fine except the entertainment was not working for half of the flight.

Easy boarding with an extremely kind attendant. Seats were spacious and we had 3 seats for 2 people so we could stretch out. Comfortable air flow and very attentive and hospital attendants. Bathrooms and food were the only negative. Bathrooms were so small you could hardly get in and close the door. I don’t think an obese person would fit or a person with a movement disability. Food was the trending food for flights, nonexistent. We spent $40 getting sandwich and snack at airport for our 6 hour flught.

At first, we were on the runway for about an hour, literally. The Captain did explain that the Control Tower just had a change shift (sounds like an unrealistic excuse) and then that we had to change a runway. A regular economy seat is made for 12 yo twiggy. I understand Delta wants to push for an upgrade, but after sitting in a Comfort seat and in First class. I would say First class is not worthy of my money. The landing was delayed because of the weather in NYC, I don't hold that against Delta, of course. The Captain did alert us to that upon takeoff in Vegas and again as we reached NY.

No one fussed at me about my pap machine as a 3rd pice on the plane. Boarding was pleasant and smooth. The boarding agent in Anchorage was a fun character- he could be in a movie. :~) The on-board crew were downright pleasant. No militant attitudes on Delta. Like all planes these days the seats are too narrow for standard Americans and at 5’2” there is barely enough leg room. I don’t know how tall people fold themselves into the seats. But that’s nothing specific to Delta

Great. Very smooth. Plenty of information. However, wish they would give out a menu in advance of making a dinner choice like other international airlines. The flight attendant says chicken or pasta and there are details about ingredients or spices requiring the passenger to ask which requires the flight attendant to answer many times. So easy to solve this problem. P

When I booked the flight, I wasn't aware that this was a "no frills" flight. No wifi, no reclining seat, no complimentary soft drinks.

In business class overhead bins were minuscule. Had to use cabin staff to find a place for my carry-on bag. Boarding process was shambolic, as “passengers who needed assistance in boarding” absorbed an excessive amount of time and attention that Aer Lingus was apparently unprepared for.

Aer Lingus was fabulous.nhowever, Aiirfare Assist who Kayak routes me to to purchase tickets for m was awful. They messed up my reservation so bad that after about six hours on the phone with them over the week before departure, I had been choice but to show up at the airport. The Aer Lingus staff were amazing and got it sorted out but I would recommend not using Airfare Assist.

It was excellent! The plane left Chicago early. Arrived in Dublin early. The crew was excellent! It was a great experience.

The Nice airport was a horrible boarding experience. I have never experienced the kind of compressed mob (in the B12-B17 gate area) of people all unclear what was happening and no airport staff to assist. There was no signage and 1000’s of people waiting for any info for 2 hours.

No entertained. food and beverages were not complimentary. they lost my checked luggage which made my 10 day vacation unpleasant.

The food was mediocre, the coffee was terrible. The entertaining selection was plentiful. They lost my checked luggage which put a damper on my 10-day vacation.

Flight was on time. Boarding was quick and efficient. Seats were comfortable. Food was fine.

Weeeeeeell, you folks know economy class on Airbuses well--you're packed in like sardines. We may actually spring for more expensive seats next time, with a little room to stretch out. NO room to stretch out in Airbus economy class! :-) Apart from this, the food was decent (considering that it's mass-produced, and has severe spatial restrictions of its own), the staff were friendly enough, and there was a wide selection of movies, etc. to watch. Overall, I'd tend to use the word "adequate" rather than "exceptional" for my experience. But really, how could it be otherwise?

The ease of boarding was good. I wish they had something to eat on the plane.

The long wait at JFK made the trip horrible. Also not having enough buses when we deplaned was annoying

Flight was delayed on 6/20 to miss international connection. Next flight out was 24 hours later. Not acceptable.

Terrible! I had to cancel our flights due to my wife Carmen requiring an unexpected second cancer surgery. I first contacted orbitz about obtaining a credit due to medical interruption and orbitz directed me to TAP. I contacted TAP and the representative directed me back to orbitz and refused to even explain what TAP’s medical interruption policy was or how it worked—I wanted that information for a second call to orbitz. Terrible service at a particularly difficult time.

Flight from FNC to OBO was cancelled. We were rebooked to Lisbon later in the day. It was inconvenient but it worked out ok in the end.

Food was edible, not great, and served by attendants who looked like they really were not happy working the flight. The section I was in was too warm making the 11 hour flight uncomfortable. Other areas on the plane were fine.

Checked bG chstgr was extremely high. Over $120. It was s bsit and switch knowing an international passenger would have t9 check a bag.

First, communication was terrible. The gate on our ticket was not what was reflected on the airport screens and TAP personnel were not present at either gate to answer questions. The flight was delayed and there was no announcement. Also, there was an equipment swap to a smaller airframe which affected our level of comfort. The root of all these issues was as a lack of communication. With air travel in foreign countries already being a stressful affair, lack of communication needlessly raises the level of difficulty.

On time, politeness, food okay but entertneiment mediocre with only old movie and the so called new we’re 2 or 3…

The crew was very nice. The food was good. The entertainment on the way back to Miami wasn’t as good as the flight over. I wanted to watch Wicked but on the way over from Miami to Lisbon but the screen didn’t work. On the way from Lisbon to Miami Wicked wasn’t an option. Liked the option to check out overhead carry on with our checked luggage Overall the flights were very good. I would fly TaP again

Awful. I told them to cancel my return flight and they didn’t then charged me +$800 days before the flight for a biz class upgrade bid. When I called to confirm cancellation and get refund on buz class upgrade they said I had to go thru orbitz and it was too late. Scammers. Beware.

Good service. No complementary food for international flight. WiFi kinda pricey. Got the job done for the right price.

Still one of my favorite airlines, but the entertainment options were a bit lacking. It didn't help that my screen didn't work on one of the legs of the trip.

The plane was very small and the aisle was so narrow that every time someone walked by they rubbed against me, so it was very uncomfortable.

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

Overall good for an economy fare. IMO the movie selection could be improved. Great that you can now connect bluetooth headphones to the entertainment system.

Paid for a Premium seat...minimal recline, no footrest. Maybe slightly wider than a cheap economy seat. Zero chance of getting any rest on this plane

Seats in premier saga class were narrow and hard. Very uncomfortable for a 5-hour flight.

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset.

I had an exit row and so was Comfortable on the long flight.

The seats on this airline are sooo small, even for a petite person. I felt like the seat tilted forward and I was fighting to stay in it. The lavatory is horribly small, with a wet floor because the sink is so small you can't help but splash the water all over when washing up.

They’ve lost my bag and I have no way of really getting in touch with anyone and have received no updates.

Very crowded, no real explanation of food "chicken or pasta?" After dinner no drinks service. Plane was clean, but little help with finding soaces fir luggage to get into overhead bins. Many passengers putting 2 bags, hats, duty free in overhead bins so no space for roll ons

The airline was efficient and accommodating to work with though there was a delay. Appreciate the service and smooth experience!

Flight was good but seat in 12D was not comfortable, better on the Airbus 321 from Tampa to Charlotte. No breakfast was served before landing in zLonfon only a coffee and orange juice.

I was transferred to an American Airlines flight. The boarding was late and unorganized. The seating was extremely tight and uncomfortable. Will not use AA again.

The entertainment selection was ok, but overall not bad! The crew was great.

Good crew and boarding process. Horrible food and one of the most uncomfortable aircraft seats I have ever sat in. The cabin temperature was warm which made it hard for my family to sleep.

bad, made it to connecting flight and they didnt let me board

We were never able to take this flight because our first flight from Austin to Dallas was cancelled.

Our flight was cancelled on Sunday morning. We were supposed to take a short flight to Dallas from Austin, then a nonstop to Barcelona. We were rerouted from Austin to Miami on American Airlines due to storms we sat at the gate for 2 1/2 hours, pilot announced we needed fuel. In air pilot said we were rerouted to Fort Myers 30 minutes from Zmiami. Sat on tarmac waiting for a gate. Deplaned at 10:09. Pilot gave conflicting info about what to do. Missed Miami flight to Barcelona. Pilot announced crew was timed out and we would have to wait for a new crew. Waited a couple of hours. Got to Miami at 2:30 am. Gate agents at Fort Myers told us to go to D30 for hotel vouchers. No one was there. So we slept a little on the floor. Husband is 80 and I am 74. Rerouted to JFK at 9:54 am on Monday, then flight to Barcelona at 5 pm. We arrived in Barcelona a day late and missed the first night of our Oceania Marina cruise. We feel that we are due a lot of compensation for this trip from hell.
