The TN A300 in 1981 was well before the AN 767. They served the country well for almost 20 years. A HUGE jump from the then biggest aircraft in domestic ops (727). They were great for freight and pax loved them. Although remember this was a different era when they could operate at 70% average loads and still survive charging fares that were 4 or 5 times todays discount fares (in adjusted terms).
