Flying to Europe via Asia with Finnair Business Class

We flew Melbourne-Singapore-Helsinki-London-Helsinki-Hong Kong-Melbourne on a multi-destination ticket. This fare allowed 3 stops so we opted for Helsinki (with St Petersburg only 3.5 hours away on high speed train), London and Hong Kong.
Watch for Business Class sales with Finnair. Unbeatable price. Finnair has other Asian destinations for stopovers. The flight to Hong Hong was a remarkable 9.5 hours. We had a tight connection LHR-HEL-HKG but the Finnair gates were close together.
Helsinki Airport (Vantaa) is expanding. You may have to use a bus rather than a sky bridge to board your plane (e.g. HEL - LHR).
A train station is underneath Terminal 1. Fare to Helsinki Central Station ("Helsingfors" on noticeboard) is 5 euros. Travel time 28 minutes.
On the LHR-HEL leg, the Business cabin was just a curtained-off section with Economy seats, but the middle seats were left vacant so you could stretch out. Service was definitely Business.
On the long haul flights, if you are a tall or large person,you might find the lie-flat beds a wee bit cramped (especially the foot well).

Food in Business Class is plentiful - wholesome/comfort food rather than fancy/fiddly.

 Baked salmon for dinner Singapore-Helsinki

Cameras in the tail and under aircraft make great viewing in A350-900 planes, particularly if you have a middle seat in the plane.

Huge breakfast - but there are other options if you want something light.

Suburban train links directly with airport. Central Station Helsinki is 28 minutes away.
