Hi, I'm looking to book a specific business class flight with Finnair and need advice on where to credit / which oneworld program to join.

Finnair offers these 16 options:



(1) What is most important to you in a FFP?
Extra baggage allowance and generous carry-on allowance
Faster check-in and security
Flexibility in terms of combining and using the miles / points, points expiration

(2) How many miles do you usually fly each year & in what class? How many flights/sectors?
Hard to predict as I am just starting to travel.

(3) What types of fares do you usually buy?
Planning to fly Business class especially on long flights
Will be looking for good value Premium Fare deals.
Occasional short flights in Economy possible.

(4) Can you choose your airlines and/or class of service? Do you travel for work and/or pleasure?
Yes can choose freely, pleasure only. Happy to do mileage run itineraries to attain status and see new places when opportunities come up.

(5) Which routes and airlines do you fly most often?
Asia domestic, Asia - Europe, Asia - North & Central America

(6) What is your home airport?
BKK, HKT

(7) Do you have FFP status of any kind in OW or other airline? What is it? Do you have any miles banked in a FFP?
nothing at all yet

(8) Preferred Airlines? Most common Airlines flown on?
Not enough experience to prefer any.
I hear Qatar is good.
I used Oman Air in business between Europe - Asia before and it was ok.
Malaysia appears to have the cheapest business class fares within Asia.
Looking at this Finnair Business class flight between Asia - Europe now.

Other things to note
I will fly with a family member so combining the points / miles of two accounts into one (head of family account) might be a factor.
Since I don't know whether or not I will fly enough to even get status or use points, flexible usage of the points / miles as in transferring them to other people outside of the family or to another program would also be good.
Long expiration times of the points.
I do not reside in the US and do not hold any credit cards that would allow me to earn extra points / miles.
