FAQs - booking Finland flights

  • Can I bring my pet with me when I board my flight from Boston to Finland?

    Each airline has its own policy regarding pets in its cabin. For example, Finnair allows cats and dogs in the cabin. Your furry friend must be kept in a carrier, and both the animal and carrier together cannot weigh over 17 lbs. and must fit under the seat in front of you. The airline usually only allows two passengers with pets on a flight, so you should make sure you book as early as possible, and you should contact the airline regarding any other conditions or fees.

  • Where should I fly to in Finland if I want to visit Santa’s Village?

    If you want to visit Santa’s Village in Finland’s Lapland, you should fly to Rovaniemi Airport (RVN), which is only about two miles away. From Boston, you could find options such as one-stop flights with Air France through Paris or two-stop flights with Austrian Airlines with layovers in Washington, DC, and Vienna.

    Currently, there are no direct flights to Finland from Boston.

For smaller airports, such as Ivalo Airport (IVL) in the Arctic Circle, you may find one-stop flights, like those through Frankfurt with Lufthansa, but there will usually be more multiple-stop options, such as Finnair through New York and Helsinki.

  • Will I have to wait long during my layovers between Boston and Finland?

    You may prefer a journey that has stops, but you may not want to wait long between flights. You can use the “layover’ filter in your KAYAK search, so you could find, for example, flights to Rovaniemi Airport (RVN) with layovers of less than two hours each, such as with Air France through New York and Paris.

  • How does KAYAK find such low prices on flights from Boston to Finland?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional round-trip ticket. You could then fly from Boston to Finland with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from Boston to Finland?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from Boston to Finland up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

I thought the service was very nice and pleasant. There were no hiccups and no issues so overall a good experience.

It was a pleasant surprise to have complimentary Wi-Fi on the flight

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

The baggage belt was not updated on the Delta App and was displayed on the wrong belt board. Was not expecting this to happen.

The plan was delayed and left DC 90 minutes late. However, it showed a 20 minute delay on the delta app, then a 12 min delay. It turned out to be an hour delay. I found out where the plane was with flightaware. Stop keeping customers in the dark about what is going on.

Pilots lied about waiting on “paperwork”. Sat in the plane for over an hour, waiting on some papers to be printed according to the pilot and then all of a sudden he says good news maintenance is finally on their way. Maybe they can fix it before we get our paperwork. Ended up missing my connection in LaGuardia and as a result, had a fly home to Lexington instead of the Louisville airport. Then paid $100 to uber to Louisville since it was midnight by the time I got in. I wish they would just be transparent with passengers sometimes and not try to beat around the bush on why things are delayed.

One of the flight attendants was a little cranky. I appreciated the free wifi and plug to charge my laptop

The flight was smooth, the crew was great but the plane was quite old

The flight was delayed 90 minutes The Gate was wrong The Restroom on Aircraft was not clean There was a half used water bottle in my seat

Cabin was not pressurized properly. Several passengers had respiratory difficulties.

The seats are very uncomfortable. They never have tomato juice. Usually late

Finnair was not able to get our luggage on a connecting flight and there was a substantial delay of two days to obtain our lugguage. They did not communicate well, and we had to travel a significant distance to finally get our luggage. It has been a very negative experience.

On a more than 8 hours flight was only one meal included, which I have never experienced before. Always two meals on the overseas flight. It was very weird.

Business seating is soooo uncomfortable. You can sit straight up or lay down. You need pillows behind you because the back doesn’t lay down. Those are need to “prop” you up. The chair has no padding whatsoever. Food was gross. I’ve eaten on Finnair before and the food was exceptional. This time it gave 2 people in our party diarrhea. It was the chicken dish. I took 2 bites and didn’t eat anything more. The flight attendants were nice. You needed an additional lounge in Terminal D at DFW Airport. After waiting 40 minutes to enter, we finally gave up and went to a bar across from the club doors. I’m unsure if I’ll ever book a Finnair flight again.

It was a good flight, very comfortable seats for sleeping in business class. Probably the most comfortable business class seat I've ever had (20+ times in business class on various airlines). Service was good, but the only downside is my screen didn't work and it had to be reset multiple times to get it to shut off. I had to block my eyes because the screen was white almost the entire flight and I wore an eye mask when I slept. But when eating and reading in my seat, my eyes hurt because the only way to turn the screen off was reset it and the screen would only be off for a few minutes at a time.

Everything was wonderful! AirBus seats are more comfortable to sleep in as compared to the Boeing planes.

Great. It was awesome to have boarding from the front and back of the plane as it made the process go very quickly

The staff were all particularly great. The plane was clean and fresh. The bassinet worked great. It was all very nice.

The entertainment offerings were not as good as I would have expected, but the service was very good, the crew helpful, and the flight on time! A very pleasant experience overall.

flight was excellent. The crew was very helpful. Finnair made this 10 hour flight flyby. The entertainment screens on every seat really help save the battery life of your personal devices. We were served dinner and even a light breakfast, both of which were tasty. The crew even did all they could to help one group of passengers with their child, as to keep them comfortable during the flight.

Old plane, food not that great - lacked taste. Crew was nice but strict.

Terrible airlines, kept lying to me about the fact that my connection flight was cancelled. Left me hanging until last min. NEVER AGAIN

Cancelled my flight. Only option had a layover in Italy. No compensation for the 4 extra hours of travel time. The travel agency, cheapflightfares, blamed Scandinavian airlines and said there was nothing they could do. Scandinavian airlines said since it was booked through a travel agency there was nothing they could do. The entire thing was incredibly frustrating. Never booking through kayak or with Scandinavian again.

The seats were really cramped. The high backs on the chairs made you feel claustrophobic.

Flight delayed 3 hours 45 minutes. Connecting flight changed. Would have missed cruise ship. Had to cancel return flight, because we couldn't just cancel flight to Nice.

First off, numerous things were misrepresented. When we purchased the Economy Plus tickets the fare allegedly includes access to lounge. At Logan Airport where the signs points to, there is no longer SAS lounge. We were directed to Delta lounge, which is located at the other end of the terminal. When we got there, Delta reps told us that it is for SAS business class passengers only. The advertised seat selection 30 hrs prior to departure did not work online. When I called SAS, they told me that it was more than 30 hrs before our connecting flight in Copenhagen, although it was less than 30 hrs before the departure for Copenhagen. Customer service representatives would not provide any assistance. The tray table in my seat was not fully unfolding to be able to place the food tray on it. Therefore, I had to keep it on my laps.

Everything went very smoothly. My only complaint is how cramped the seats are for an international flight.

They were charging $$$ for first glass of wine. That first glass should be included in such a high price.

Good could have been better. Comfort was fine with decent leg room and seat comfort. Would have appreciated a USB-C charger port.

TERRIBLE! Staff was unfriendly, rude, and demeaning. One flight attendant touched me to grab the complimentary blanket off my neck because I couldn't take it home, while a bunch of other people took theirs home. I have never been so ill treated. I am not happy at all. And flight was delayed, no information until short notice for everything. Lost an entire day at my destination. I expect a full refund for that experience. Never will fly with them EVER again

Because I bought my ticket from Underpricer, I could not check in online. I could only check in at the airport and that was deeply frustrating because I had to arrive very early. The flight also departed 45 min late and passengers were given no explanations about why we were delayed. I was worried I would miss my connecting flight. Once on board, however, the flight was fine.

Terrible boarding and first class experience. Nice staff but overall disorganized, dirty plane.

The flight was delayed significantly and we sat on runway after landing for awhile. Best thing was the flight attendant, Jenny, in first class, who was very professional and attentive. She was excellent - the rest of the flight was not.

Early departure meant on time arrival. Only real problem was free internet had issues, although chatting with the internet help desk (you can do this via aainflight.com) got the issue resolved.

The staff and service on American Airlines were truly outstanding. I had requested wheelchair assistance for my mother due to her knee issues, and the team went above and beyond every step of the way—from boarding in Boston to our arrival in Chicago. Their care, professionalism, and attentiveness made the entire experience smooth and stress-free. I’m very grateful for the support they provided.

Found that the plane used for this short flight is smaller and therefore the seats are really squeezed tight.

Tv screens and movie selection v good. Friendly staff. They were really worried about max capacity and room for carryons. That is never fun but i had no problem finding space when I boarded.

Great experience. Good dinner and service. FA's were very nice and attentive.

Jill was the flight attendant in first class she was fabulous!! Best flight attendant I have had in years.!! And I fly every other week. Other can learn from her!!

The business steward was absolutely amazing! Smiles and kindness! Wish all AA flights are like this one!

On-time arrivals and departures. Crew helpful and friendly. Yet everything costs extra: seat selection, food, even airphones!

Delays at check-in, seemed like they were short ground staff at the time and some passengers needed extra processing.

Food - Non-Existent. You pay for everything. It is strictly Pay-to-Play!

There was no lounge at Boston for us to use. Typically flying first class overseas comes with lounge privileges. The seats did not recline even a little. My headset only worked on one side. I felt like I was flying on Ryan Air, not Icelandic Air.

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.

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

Everything was great! My only critique is 25 euro for wifi is wild, but I get it

Staff in flight and at the airport were very helpful. A short time between flights made it stressful to get to the connecting flight and we probably would not have made it without the staff’s help.

I liked how easy my transfers between flights in Keflavik were. I would have appreciated more food options in Keflavik.
