Once I was scheduled to return home from business on Saturday morning. I decided to spend my own money for a few more hotel nights and spend the weekend out there. Then I took the red-eye home on Sunday night (approx. 9 PM PST - AM EST). Unfortunately I learned too late that that airline would have upgraded my full fare (company paid) coach day ticket to a first class red-eye ticket.
I was not fully attentive on Monday morning but that is another program.
