LH pulls out of IATA YY fares
It seems that Lufthansa is no more accepting IATA YY fares. What are IATA YY fares you ask? These are full fare, fully flexible fares that in theory can freely interchange between airlines (hence YY airline code is used) – ie they can be extremely useful indeed, especially if bought from a cheap location in first or business class. For more background on IATA YY fares check out the mileage run forum.
