Lufthansa Lifemiles Award booking upgrade later
I have multiple Lufthansa bookings via Lifemiles and I am hearing that LH is making most business class seats available 14 days to departure. If I want to upgrade my ticket is it $150 per ticket plus the miles from Lifemiles? Is it the net Lifemiles? If I paid 30k and the biz seat is 63k - just need to provide 33k?
Much Thanks!
