My experience is that if you surf into the flightcompanys own websites, you will often find the best prices. At least Estonian is much cheaper if you buy the ticket directly from them on the internet. Also same story with Ryanair. ALso SAS even if they are more expensive. I think it is the same all over, but you have to check it to be certain about it.
I think I heard somewhere that people from St.Petersburg could travel freely into Finland, I don't know if this is true or not, but that might be an option as well. May be next time you could meet there, because then you would not have to worrie about Visa at all...
If it is a fact I don't know, but someone once told me. Check it out
Norway,
Please don't confuse low cost carriers with regular airlines. Just out of curiosity, can you check out some prices on this link, I find it's the best site in UK, this is the NO version:
Yes, I have checked them earlier, it is not too bad at all I think. For tickets to Ukraine I find them the cheapest, but from Oslo to Russia it is actually cheaper to call Aeroflot directly. Same goes for Estonia. BUT, when that is said, I haven't been doing too much research because I have been pretty satisfied with the prices Estonian air had to offer, I just didn't bother searching for a better offer. You know Martin, I go to Estonia roundtrip for about $150-$200,- And that is a direct flight with no stops, takes about an hour or so.
I think Moscow is about 2.5 hours from here by plane, and the price last time I checked was about $300.
but kelkoo was quite good on several flights. Not a bad place to start at all I think when you are serching for good prices.
I dont belive St.Peterburg people can go to Finland visa free, but its easier them to get visa. Very cheap way to go St.P is to fly Easyjet London to Tallinn and take Eurolines bus to St.P.
Important!!! I found I could not beat the agencies price. I think they have a thing with the airlines. You may try Aeroflot. I used Cinderella travel agency and I could not beat any price on airfare or hotel they got for me. All went very well and the lady complimented on the organization of the arrangements. Enjoy your trip and best wishes.
