It's a good airport. The net is large, duty free is not so much the cheapest, but occasionally there are good discounts. The catering is normal and there is a grocery store with a good salad bar. It works 24 hours. Finnaair has not only independent check-in, but also baggage check-in. You print out the sticker on the suitcase yourself, stick it on the handle and drag the suitcase to the tape. But there is a "help". Please note, the airport is designed so that it can be a very long walk to the gate, just 20 minutes. The train station with trains to the center of Helsinki is right there, no need to go outside or walk through long passages. Train to the center every half hour. 4.1 euro ABC zone ticket.
Over the past two years, it has become almost the main airport for me)) A calm, safe, well-equipped airport! The waiting rooms are very comfortable, there are different areas, both for children and those who even work on the road) The most impressive thing is the high–tech inspection, modern scanners, thanks to which you can now pass with any liquid up to 2 liters! There are only three of them in the world so far, and one of them is Vantaa! The geography of flights is not so big, which I like on the contrary, since there is no noise and hubbub and pandemonium of tourists! I recommend it!)
A top airport, of course I have not been to Moscow airports, they say even more, but this one... It's like a separate city. According to the store, everything is super. A huge plus is the seating area, sun beds, and saddles. Very comfortable
