I got this email from Qatar Airways. From what I understood to be eligible for 500000 extra qmiles one needs to fly on the launching flight to every new routes from 3 Aug 2017 to 31 March 2018. There are already 3 new launches scheduled for August, 08/08, 21/08, 28/08 to Sohar, Prague, Kiev.
Not easy I think but might help some. One-way flight is allowed so one can possibly fly to/from Prague/Kiev on the same trip.

These routes involve transiting through Doha … I'd be cautious about that, given the trade dispute and airspace bans that's currently apply to Qatar airways.
