Yes I know I am supposed to do a search, and trust me, I usually do, but the new search has not been kind to me, so please forgive the transgression...

I am in the process of booking a plane ticket (DXB-DTW). It will be expensed back to my company, but I am only allowed to book economy.

While booking, I am getting an option to upgrade my itinerary for $300ish + 40K miles. Since the company is paying the base fare, that's not too shabby (I feel) for WBC. But, I am thinking that there will be problems getting the expense payment sorted out if there is an extra line item on the receipt.

So my question -- can I book the ticket and then call to see if I get the same deal? And then the 2nd question -- is this a good deal?

thanks!!!
