American Express has been running a promotion in Europe (read more here) for bonus Membership Rewards points and enhanced credit when using them towards statement charges.
The offer for cards issued in Finland is double Membership Rewards points (3 points per Euro on Platinum) and double value when used against statement (1 point = 1 cent).
Note that you usually have to use 2 points per 1 cent credit in Finland (not good). You can only transfer points for a limited number of airlines, and none of them is at a 1:1 ratio. They are usually 5:4 or 3:2 Membership Rewards to a mile.
I have not found the Amex Platinum issued in Finland to be worth the price (60 euros per month) as it is not as benefits rich as the card issued in other markets (if you have access to them).
It does come with travel insurance that could be worthwhile if you were swiping this card for most transactions AND make traditional trips (there is a limit on the number of nights a trip can consist of).
Priority Pass is beneficial when you can travel (no bans or restrictions), and even when you have an airline or flown class provided access (sometimes PP ones are better).
The main drawback, however, is the foreign currency fee for transactions not conducted in Euros that is anywhere between 2% to 3%. So, I only try to swipe when in the Euro area, although the transaction above that came from Virgin Atlantic is in GBP (more of that redemption tomorrow).
The Amex is good at, however, approving more significant transactions for airline ticket purchases that I often use it for. It doesn’t choke when a charge for 8K EUR is coming through for an RTW ticket.
