And the Ryanair option... You would have to book two separate flights, for example Pisa-Frankfurt-Tampere, or Pisa-London-Tampere. If your first flight would be late you might be stuck at London or Frankfurt without refunds. On the way back you would have to stay at London or Frankfurt for the night. So I don't think Ryanair is a viable option for return flights.
Anyway If you want to come don't think too long, but just go ahead and book the flights with Sterling or/and Blue1, or even Ryanair!!
Don't mind about the arrengements at this end, we can work them out later. It would be preferable that you'd be here by 17:00 on friday though.
I'm driving to the con from Helsinki, so you can get a ride there with me. I can also pick you up from the airport, no matter what time you are arriving, and provide accomodation if needed.
