Thanks, Gardyloo; the route is comfortable, but I'm trying to see one other place, so picked Helsinki over London twice.

number_6, I checked the flight on Finnair site, where they say it is operated by Finnair. Thanks for the caution.

I was surprised to see that some flights on oneworld's timetable aren't actually eligible. This is a different issue from Global Explorer's adding 3 more airlines to oneworld Explorer.
