Q. Why does TranStats have missing Service Classes in Schedules T-1 and T-2?

Answer

  • Service classes K, V, and Z were removed from Schedules T-1 and T-2 in the Air Carrier Summary Data because they were duplicates of other services classes. This duplication was causing confusion and misuse of the data.

  • The Z class in T-2 was restored because the fuel consumption data was linked to that class.

  • Since there was no similar situation with T-1, those classes were omitted.

  • You can add the remaining service classes to get the totals:

    • K = F+G, V = L+N+P+R, and Z = K+V
