Hi all & thx for the great forum!
I would really appreciate help in choosing a oneworld FFP.

Best Oneworld Frequent Flyer Program for you?
The answer to this question depends very much on your personal travel profile and objectives.
- what is your definition of best?

Best possibilities to claim flights with miles.

- do you value miles/points (or equivalent) for redemption over gaining status?
To be honest I havenīt fully grasped the concept of miles in this context.

- do you fly enough to gain any meaningful status?
I would assume not

- what do you want to use the miles/points for (award, upgrade, hotels, what ever)?
Flights flights flights

- what sort of flight award is of interest (destination, class of travel)?
Economy/Coach; preferably within Europe but could see spending miles on longer holiday trip to US/Asia.

Mostly interested in flying out for weekends/extended weekends.

- are you interested in topping up by paying cash for miles?
Yes if necessary/good value (but donīt see myself spending more than low 3-digits

- which airline and where do you normally fly?
Cheapest/best connections; all around Europe; no regular destinations

- are you primarily a leisure or business traveller?
leisure

- where do you live?
Helsinki

- do you have other ways of earning points in the various programs, e.g. credit cards, shopping, etc,?
Only reasonable offer I have seen so far would be Finnair Plus Diners but I would think at absolute maximum Iīd be capped at around 40k points per year at current terms. To my understanding AAdvantage credit cards are not available in Finland.

Super-rarely stay in hotels (that would be part of a program at least).

Questions
For members asking for information, to help people to assist you, can you please provide:
(1) What is most important to you in a FFP?
Reply: Basically my only goal is to get free/cheap flights. Mostly in within Europe flying out from HEL, but I could see myself using miles on flights to US or Asia.

Baggage, lounge, upgrades, hotels I donīt care about.

(2) How many miles do you usually fly each year & in what class? How many flights/sectors?
(<25000, 25000-50000, >50000 miles - <25, 25-50, >50 flights?)
Reply: 5-10 return/multistep flights in Europe; as far as I can tell <25000. (Have possibility&resources to mileage runs/trips partly motivated by miles so hoping this could be more)

(3) What types of fares do you usually buy?
Reply: Economy/cheapest. Often choosing destination and/or time of travel at least partly by fare. Mostly look for discount tickets

(4) Can you choose your airlines and/or class of service? Do you travel for work and/or pleasure?
Reply: Within oneworld Iīm flying out of Helsinki so Finnair dominates lot of the market. Within restrictions of HEL I can choose airline. Do not fly for work.

(5) Which routes and airlines do you fly most often?
Reply: In Europe

(6) What is your home airport?
Reply: HEL (Helsinki)

(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?
Reply: No

(8) Preferred Airlines? Most common Airlines flown on?
Reply: No. Choose by fare. Thinking back last ~5 years mostly flown Lufthansa and Finnair or Finnair affiliates.

OTHER INFORMATION:
Reason Iīm asking I have
HEL-MAN-HEL, HEL-LHR-EDI-HEL, HEL-PRG-HEL coming up within next 3 months. I have difficulties estimating what these flights for example would earn me. In addition thereīs a special hotel bonus that I will claim that would earn 10-15k Finnair Plus points.

To my understanding there has been relative upgrades in Finnair Plus T&C and AAdvantage is changing their terms which is why Iīm a bit confused on the best option even after Iīve tried to do my research.

My current plan is:

1) Join AAdvantage and use the credit the flights (above) there (better program for my purposes long term, Finnair punishes discount/cheap tickets heavily? Though AA will be doing this too very soon? Would I still get these flights (by May) in under the current system?

2) Join Finnair Plus and claim the hotel booking bonus to kickstart my account. Figure out how to earn more point later. (FWIW the same hotel bonus for AA was only 1000 points).
At some point I probably will for example get a special offer on the Finnair Plus Diners right?

Thanks for taking the time, would really appreciate any input to keep me fro second-guessing!
