I'm contemplating the possibility to start flying more OW, mainly because AY network is getting quite good for my travel pattern (let alone the SK service 'enhancements'...), and also because I spotted a really nice BA I-fare that would fit my upcoming HEL-NRT trip

The question is whether FinnairPlus is the best programme for me or should I rather switch to something else? From reading this forum, I gather many people suggest AA or CX. However, I parctically never fly AA and don't anticipate to do so much in future either, and upgrades are definitely my top-priority for burning the miles eventually earned.

I may actually fly CX a bit, but only 25% class of service bonus is a bit of a drawback, since I sometimes do fly long-houl business (like the planned Japan trip).

My main objective would be reaching and maintaining status; I tend to tarvel long houl busines or premium economy 2-4 times / year, and quite a few intra-european trips on cheapo tickets. However, my travel pattern may change quite a lot in long term.

My own research suggest that the progarmmes to consider are AY, BA and possibly MA's Duna Club, but the post OW accession rules haven't been released as far as I know. It seems that reaching status is more or less equally hard in all OW programmes (unlike *A that has lot of variation in tresholds). For example the HEL-LHR-NRT return trip on BA I-fare would give me:

320 BA tier points (80% of required 400 for Silver) OR
45,868 AY points (76% of required 60,000 for Silver) OR
17,812 CX miles (60% of required 30,000 for MPC Silver)

If MA is going to count OW flights against status, I reckon this would generate 28,050 Duna Club miles (70% of required 40,000 for Silver).

So, it seems that after all, AY is not that bad for me, especially becuase it looks unlikely I could ever make OW Sapphire in any programme and:

• HEL is my current home base, and AY Silver would give me lounge access for AY flights departing there
• BA doesn't give any tier points for cheap fares
• AY would be the most likely place to use for upgrades
  

But have I missed something? Any other suggestions? Or perhaps I should just stick to *A where I can renew the Gold status fairly easily...
