I actually didn't spend a whole lot of time in Helsinki I arrived at the airport at 11:30 pm Tuesday evening stayed at the Hilton attached to the airport, left at 8 AM for Aland Island returned 12 hours later, straight back to the hotel to sleep then up at 6 to catch my return flight to London. The flight from Helsinki to Aland was neat as I got to check out the archipelago. Aland Island is autonomous from Finland. The most interesting thing I learned about Aland is that foreigners are not allowed to own property. You must live in Aland for 5 years before you earn the right to purchase property.
My boarding pass for the AirAland flight was the most interesting boarding pass I've ever seen. A simple laminated sheet. When I boarded the flight they didn't ask to check my ID or anything just took the boarding pass and on I went. Nothing like at Heathrow where your boarding pass is checked 4 or 5 times, even after you get on the plane.
The flights I've taken this week put me officially over the 25,000 mile mark and 9 cities and it's only February 20th. I'll hit 30K miles by the beginning of March after my trip to Egypt. If this keeps up 100K miles shouldn't be a problem.
