these are miles that can be collected in the account of a member and be used to buy flights, upgrades, merchandise from the lufthansa worldshop and other miles & more partners. for standard miles & more members they retain validity for 36 months, after which they expire. (miles are not extended by having any activity on the account as with most other airlines). for frequent travellers, senators and hon circle card holders, the miles have no expiration date. however, as soon as a customer does not hold any of these cards any more, the expiration date of all miles is set to 36 months counting from loss of frequent flyer status. for miles & more credit card (visa or mastercard) holders issued in several countries, miles have no expiration date as long as the card is held and/or used. if the credit card contract is ended, the original expiry date of the miles is reinstated; although the earliest miles can expire is at the end of the quarter after the credit card contract is ended.
