Anyone here who got successfully rerouted by Qatar airways recently?

We have our flight on March 22 and we are waiting for official cancellation hoping for a possible reroute. Anyone here who got successfully rerouted thru Qatar Airways' thru partner airlines like Finnair, Cathays Pacific, or Malaysia Airlines? We are travelling from Oslo to Manila via Doha originally. Really appreciate if somebody could share their experiences about this :) I have no idea how realistic it is to hope for the change date option and how long one must wait regarding the 14days maximum flexibility change date window.
