Found a spreadsheet with the base prices from various countries that one of the other members here posted in another thread. Looks like DONE4 will be quite a bit more than LONE5 so out of our budget.

Flying pattern in future will be occasional flights (annual likely) from UK to Malaysia & occasionally through to NZ to visit the families on both sides. Otherwise will be around Europe/Middle East for travel.

Status would be nice to get the perks associated (lounge access etc) but award flights or award upgrades is probably what we're keen on.

With Finnair is it easy to book award flights on other OneWorld carriers? as I doubt they fly many of the routes we're thinking of.
