Goldenair - I couldn't remember the name of the operator last time I was up that way (few years ago), I do remember a whole more civilised approach to Airports and Travel than in some other less enlightened parts of Europe.
The corporate travel provider charges a fee, the value to the organisation is that they enforce the company travel policy which will save money when you spend in excess of £1 million per year. To the individual they haven't added a whole lot that I couldn't purchase directly off the page, their implementation of an Amadeus self service booking system (reduced transaction fee) is pretty abysmal too.
I'm pretty happy to go with the local carrier (and book directly) but a 3 1/2 hour excursion on the Finnish railways system also has some attractions.
