In my former company, all travel was paid by the client and was required to be in Y. I did work with one partner who would pay to upgrade when offered the chance and bill it to the client as a "misc travel expense." She would also "lose" dinner receipts that had excessive alcohol purchases on them.
One of the best days of my life was a couple weeks after my first MR for a status challenge, sitting up front enjoying my PFD and realizing the company president had just boarded and was heading back to Y.
Thank you, FT!
