Finnair Plus sells its points at a bonus couple of times per year and currently has up to 50% bonus for gifting points through December 31, 2017.
The sweet spot of Finnair’s award chart are the short-haul upgrades from Economy to Business class (Dubai and Tel Aviv are both considered short-haul) that are priced at 10,000 points (sometimes discounted).
You can access Finnair’s page for buying points here.
Here’s the bonus schedule:
And here’s the price if you gift the maximum:
The price is 0.86 euro cents each.
I would only buy Finnair Plus points if I would be 100% sure to be able to use them for these short-haul upgrades where they are good value compared to paid upgrade prices or paying for business class outright.
Here are the the terms and conditions of this offer:
Transactions must be completed between 2 November (00:00:01 EEST) and 31 December (23:59:59 EEST), 2017 to receive the Finnair Plus Points bonus. Bonus Finnair Plus Points will be awarded to the recipient. All other Buy/Gift Finnair Plus Points terms and conditions apply.
