Thanks for the responses. I figured as much.

To clarify, since there is some question as to "why" I would want to do this. With my company, we can travel C for International trips. The first leg of my employee's trip (HKG-ORD); however, is for a departmental meeting (which is held in a different part of the world every year). For this meeting, if we have to fly, we fly Y to keep the costs of the meeting down. This is a slightly different situation where the most economical thing to do is to book the C RTW, since there is additional travel afterward. Unfortunately, you can't put 1 person in C and the rest of the office in Y, especially if the person in C is the most junior of the bunch.
