With the Barclays US Air & NFL card we have seen that if you do not use the card, within a couple months Barclays will send a spending challenge your way, for example spend 750 per month for three straight months = 15,000 bonus miles
If the same holds true for this Lufthansa Mastercard, after minimum spends you would have enough miles for (2) United First Class Saver redemptions within the USA. Pretty sweet for $79 Fee
Yes the miles will expire after 36 months, BUT these would make for great domestic travel, being that most of us save our miles for international awards.
