Upgrade strategy premium eco to biz
Hey folks! I booked a MUC-MIA roundtrip in Premium Eco Green and am hoping to upgrade to Business. It's an Allegris flight with currently 14 free seats in Business on the outbound leg and 26 on the return.
Today, LH is offering 1.380€ for a cash upgrade or 45k miles on waitlist per segment, which both seem high. A few months ago on a different flight, it was 350€ in cash or 20k miles. I know that there can be random dips between now and departure, but how likely would you say is it that the price will drop? Is it worth checking daily?
Also once I place the waitlisted miles upgrade, how would I even realize that the mile price goes down? Would you recommend canceling and re-placing the upgrade a few times to check the pricing?
