Finnair sale: Fly to Helsinki, Stockholm and other European cities from $353

Finnair has been busy in the new year as it accelerates and updates its premium flight offerings. The carrier, a member of the Oneworld alliance, just announced it is introducing brand-new seats for its long-haul business class service along with the debut of premium economy as a new class offering. The dates for the premiere of those offerings will be revealed on March 1, but until then, you can take advantage of an excellent sale the airline has going on.

There are flights to Europe departing from New York, Boston, Miami and even the west coast at great prices. It's not just economy seating either. Business-class seats are also up for grabs at strong discounts. All tickets booked by May 31 can be changed for free.

Miami (MIA) to Helsinki (HEL) is on sale for under $400 right now for a roundtrip economy light ticket. This is Finnair's barebones option, but you do get a carry-on. That's a great price for a direct flight to Finland in the spring.

Chicago (ORD) to Helsinki is also included in the sale. Most of the sub-$400 fares seemed to be gone but we found this itinerary for just $388 in March that is too good to pass up.

You can fly from NYC's Kennedy Airport (JFK) to Stockholm, Sweden (ARN), in April for just $353 in Economy Light nonstop. We actually found this great price available from March to May, so if you live in the New York City area, jump on this deal.

As we mentioned, Finnair's sale also extends to its business-class seats. The same NYC-Stockholm itinerary in business class is priced just under $6,600, which is incredibly expensive, but if you search now you can find a business class round-trip for as low as $2,213 for other routes. If flying business class is within your budget, you can score a good deal.

Miami to Moscow (SVO) in business class is available at a reduced rate.

Some nice deals to be had for west coast travelers, too. You can fly from Seattle (SEA) to Helsinki in April for $439 roundtrip.
