I kept the Y-ticket and drove there myself (300 miles one way). The Saturday following the convention, I drove myself back.
Later I applied the full-fare ticket (as good as cash) to several personal trips.
clearly unethical IMO and arguably illegal, as others noted ... it's not the same as the example under discussion where the cost to the employer is the same whether or not the employee uses the personal upgrade ...
all you were entitled to is the cost to get you there & back and if you chose to drive, then its X miles x $0.xx per mile (whatever the current reimbursement for using a POV is).
