For a domestic ticket (in normal times) there is a min 7.5% Fed Excise Tax plus $5.60 segment (max $11.20 per ticket), so if that was a domestic ticket -- it would be roughly 480 PQPs (depending on rounding) --- 0.905 of fare. And there may be some airport fees
However, the Federal exercise tax is presently suspended until 1/1/2021, so better PQP yields are presently possible.
