If you can keep both then of course it is always better, but in the end it only depends on what is more important for you

The FFP is not the only goal and should not be the main goal

If you had ask us before i would tell you to wait and apply for TK status match only when you know for sure you will fly TK and star alliance a lot (not just for 3 or 4 flights schedule for the current year) .

There is a dedicated thread for this topic Need advice on which *A FF scheme to join? - please post here , by asking lot of questions , members there can help you assess the situation and see if you would manage to reach thresholds required by TK or not

Because you can apply only once for status match , and if you cant keep both Skyteam and Star alliance then you will need to make a choice

Obviously being AMS based mean you pay higher prices in general and even highest for KL . While it is not always the case , competitors have more incentives to offer lower prices to beat main local player , and in case of AMS, those competitors are mostly from star alliance

I was using FB as my main FFP and collecting star alliance miles with A3 when skyteam wasnt available or the best option ... i had no intention of chasing a star alliance status in near future , so i went for A3 M+B cause , as far as i know , it is only FFP which is not a dead end for miles (meaning i can indirectly get them back to flying blue)

Since then my life changed and after long brainstorming i was ready to partially move my workload from skyteam to star alliance , cause i realised that wherever i go on this planet TK and/or TP follows me and skyteam wasnt always there (or prices/options werent so good) so i did status match with TP

Now i wont mind going from FB platinum to gold if i can keep star alliance gold

Maybe ask yourself if you really need FB platinum or if you would be better with FB gold and keep the money for the 120xp less needed per year for TK

As others said , to get your TK status you would need to fly TK obviously cause you will get low amount of miles peanuts by flying other star alliance airlines in economy , meanwhile with FB you can fly with any skyteam airline and the value of an XP towards your status is the same regardless of the price you paid , so you can qualify easier even flying economy only .

With FB you can get even more miles by flying with more generous airlines , like KQ or SV and collect lot of miles even when flying with relatively cheap fares . Forget about it in oneworld and star alliance

In my opinion , FB platinum doesnt bring much hard written benefits compared to gold besides free seating on AFKL , however TK elite benefits can be easily purchased and are cheaper than collecting 15k miles per year

The hard product of TK is much better than AFKL for middle haul and their world wide network is simply the best

As others pointed out in case of disruption i prefer AFKL despite all their god damn flaws (our dear veterans Johan Rebel or Goldorak can tell you a lot about them)

With FB you can , after 10 years as platinum get lifetime status (assuming it wont change soon) while TK dont offer this

So , as you see the grass isnt greener elsewhere , so it is really up to your needs and also most important your current and near-future flights patterns to guide you towards your choice
