Wanted to add my experience to this thread as I've just received 3 refunds for upcoming QR itineraries:
- HKG-xDOH-LED, DUB-oDOH-HKG;
- MNL-xDOH-LED, DUB-oDOH-MNL;
- MNL-xDOH-CPH, DUB-oDOH-MNL.
The initial flight was for my mother and had to be re-booked through MNL when Russia implemented a requirement to have been 14 days outside of China, and we didn't think COVID-19 would turn into what it has, so we booked a second flight. The third flight was for myself to meet her in Europe but not on the same itinerary. Anyway, been following along for a while, all those flights are still operating I think, however we had planned for a 2-day stop in Doha and they have taken the same hard approach as Australia in only letting their own nationals stay. Because of this, I believe this is why our flights have been refunded instead of forced into a voucher.
All flights were booked through AMEX, so I had phone calls and emails with them and they handled everything for me. Much easier to call the Platinum Priority number on the back of my card and get almost straight through, and then leave them to deal with my issues, than have to call other airlines and wait on hold, like I had to do with Jetstar for example.
While many have panned the benefits of AMEX post-devaluation, I have found them to be really helpful in all aspects of this tumultuous time and I am really happy I chose to stick it out as a card member.
