US Airways Dividend Miles has unofficially denied members the ability to redeem miles for first class flights on Lufthansa for years. And now, the program has officially documented this policy in a footnote to its award chart that reads, “Beginning Jan. 1, 2013, award redemption in Lufthansa first class cabin is unavailable.” Members can still redeem miles on Lufthansa in other classes. For example, roundtrip flights to Europe are 100,000 miles in business class and 60,000 in economy.
