Maybe I can give an update in June/July. My Elite+ status period is from Jun 2017 to May 2019 and I requalified in 2017 already for another two years Elite+.
Which means that my next status period will be from Jun 2019 until May 2021 and I already gifted two Elite cards this April.
So let's keep fingers crossed that the counter will jump to three latest in July :-)
