Under both the old rules and the new rules, if you qualified for a higher level, i.e., Senator from FTL, the old qualificaiton disappears and does not carry over to the future. The program always had the soft landing feature, which took care of this. However, with the switch to the new rules, each new status is only valid for a year. Same applies to the soft landing.
If you qualified for Senator under the new rules, once that status expires, you still have one year of FTL as soft landing.
And as others said - FTL qualification never earned upgrade vouchers. Those only come with Sentator or HON.
