Lufthansa’s Miles&More program has an unusual way of selling miles, attempting to disguise it as a “bundle” when the other components don’t make much sense.

You can purchase up to 250,000 miles in a calendar year using bundles, excluding the bonus. There is a 60% limited-time bonus for buying any of these bundles that ends tomorrow (September 30, 2025).
A great solo travel tip spotted this week on LoyaltyLobby.
