I'm not saying they 'should' do that. I'm just wondering if they might. Many airlines pause status for maternity leave even if their ts & cs don't require it.
I have never heard of something like that, interesting. Do these airlines also give extensions when you get sick and cannot fly for some time? But even if some airlines do that (which ones?) I would still doubt that QR will do this. QR is not considered to be very flexible in things like this.
But have a try!
