I had 2xJ awards booked mid May and mid June VA15/16. I saw VA15/16 were cancelled by an announcement and called straight away to ask for a reroute or be re-accommodated onto QR899/898 which QR had just announced they were restarting in May.
I didn't end up having to ask. The virgin rep offered same dates of travel on QR Flight numbers, still in J, nothing to be done on my end. New e-tickets received while on the phone.
Reroute via Singapore was not an option and she stated she could only offer Qatar/Refund/Date change.
I got the same generic email as you about 10 minutes after hanging up, but I'm glad I called and sorted it out.
We may not go given the circumstances, but I'm glad that choice is still ours and we can decide at the last minute.
