TAG achieved Civil Aeronautics Board (CAB) airline certification in October 1969 in order to fly larger aircraft on the route, only to suffer a fatal crash in January 1970 and cease operations later that year.
An October 1969 schedule showed 22 weekday flights per day each way, six on Saturday and ten on Sunday.
On October 28, 1969, the U.S. Civil Aeronautics Board (which at the time regulated all US airline service, other than "air taxi" operations with aircraft of less than 12,500lbs) awarded a certificate of public convenience and necessity to TAG to fly "large" aircraft between Burke and Detroit City Airport.
In this, TAG was challenged by Wright Air Lines, which had been offering competing service on that route since 1966.
