Q. Missing Service Classes in Schedules T-1 and T-2
Service classes K, V, and Z were removed from Schedules T-1 and T-2 in the Air Carrier Summary Data in TranStats because they were duplicates of other services classes, and were causing a lot of confusion and misuse of the data. BTS restored the Z class in T-2 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. We apologize for the confusion.
