I was really close to going to HEL during my round-the-world trip a few years back. Then it turned out that the PMI-HEL flight I was planning on was on the embargo list for OAL (I think it may have been operated by another carrier or something?) so I decided to go through FRA instead. Wish I could have made it to HEL, that does seem like a cool city.

Someday the wife and I really want to check out OSL. Her family is mostly Norwegian, and mine is partly as well. But yeah, Scandinavia is very expensive, sadly
