This takes me back
In 1989 I ran a detachment B737-200 for TEA (UK) on lease to Air Nugini. At that time we operated Morseby to Sydney, Night Stop and also there and back to Cairns and Brisbane. We did internal rotations between Moresby and Lae and Moresby and Momote. We also did an inaugural flight from Moresby to Guam. At the time they were operating F28s and A310s.
