So I see that LX along with the other LH Group are now offering multiple changes to tickets. I am not sure if this is just for new bookings or existing bookings though it does read as though it is for new which will upset a few I am sure.

Lufthansa, SWISS, Austrian Airlines and Brussels Airlines are generally changing their ticket fare structure until the end of December. With immediate effect, all fares can be rebooked several times free of charge – including, for example, the lowest light fare without checked baggage. In response to the pandemic, Lufthansa Group Airlines had already made a one-off free of charge rebooking possible in spring. The new regulation applies worldwide to all new bookings on short, medium and long-haul routes. The Lufthansa Group airlines are thus meeting their customers' needs for flexible travel arrangements to an even greater extent. However, customers may incur additional costs if, for example, the original booking class is no longer available when rebooking to a different date or destination. Any difference will be compensated for by means of additional payment.
