There's no rebooking options in my case...
If I ask them not to let the PNR be archived and I don't rebook, then if and when they return to the skies or LH does, I can just get it rebooked as per a usual cancellation right?
I understood the process is to prevent archiving and then it won't be refunded. I can see a situation where in the first few days of new operations its Y and M only and it's useful to have a cancelled ticket that could be immediately switched.
