Tango went from 100% to 0% to 25% non-status, the last change was about 4 years ago.

Is the new 50% earning for international status or non-status?

And I've never seen a Tango international fare. From LHR all the fares are T+ or higher. The only time you can end up on a Tango fare is if you get a connecting domestic flight in which case the connection is 25% non-status. Is that what you mean by T intenational? Or else where are there Tango international fares?
