Cost For Joining “Club TAP Miles&Go” For Status Match

The minimum fee for join “Club TAP Miles&GO” is $122 per year. This gives you extra bonus miles in contrast to the free ” TAP Miles&GO” program.
Cost for Buying Miles For Status Match

The minimum transaction is €70 ($78) for 8,000 miles, a one-time fee which is cheaper for the solo purpose of getting the status match.
Which Option Should You Go For?
Flight redemption using TAP miles is very high; it is not worthwhile collecting TAP miles. Hence I would recommend the cheapest option, which is to spend €70 ($78) to attain just 8,000 miles, as compared to paying $122 to join Club Basic.
By spending €70, you are entitled to Star Alliance benefits such as lounge access and other priority services, up to 30th September 2020.

Nevertheless, you should not continue to credit any miles to TAP Miles&GO program.
