We know the HA flight did not go to SFO; we also know the third airline was not UA (using ex-Pan Am L-1011-500s) or ATA

I recall BA operating fifth freedom service out of Detroit (DTW), but am at a loss for a TriStar operator from some HA destination to DTW ... perhaps a short-lived airline like Rich International serving Las Vegas (LAS)?

You are almost there, J! It was Hawaiian Air to Las Vegas and BA from Detroit to Montreal. It was not Rich Air on the LAS-DTW sector, but the airline in question has come up in a previous question here, perhaps even about the LAS-DTW route. Alright then - let's close this one out. You'd better hurry though before jlemon remembers that question and sweeps in for the kill!
