I figured out a way (I hope) that will satisfy my company and booked it as a DL ticket.
I would have tried the 24 hour suggestion if I hadn't done it before reading this. So I will not be able to help with an answer. I have my C+ seat reserved. Since it is a 767, I opted for the aisle of one of the 2 in the 2-3-2 configuration. Hopefully that works out for an empty seat next to me.
