I try to clarify one more time:

• Look at your ticket under “carrier” and you find the airline code your are booked on. This carrier counts in M&M for the 55.555 bonus miles promo.
• If you are booked on OS, look at your ticket under “flight number”: 1 to 999 counts for Austrian Airlines, 3000 to 3999 counts for Lauda Air and 5000 to 5999 counts for Tyrolean Airways. Rheintalflug (7000 to 7099) is not a member of *A. Therefore Rheintalflug does not count in M&M for the 55.555 bonus miles promo.
