In this case, there would be no need to purchase separate tkts because IAH is on the routing anyway. To 'mini- maximize' miles, just book the trip as four segments (2 outbound/2return).

How easy is it to book a multi-segment flight with a single flight number as mutiple segments? Does the answer depend on the type of ticket (paper or electronic) and how it gets booked (CO web site, CO res agent, or travel agent)?
I can think of a reason you could give for wanting to ticket this way, if someone thought you were doing it solely for the miles: If you fly a multi-segment flight with a single flight number, then you can upgrade only if an upgrade is available on all segments, but if you book them separately, then you'd be able to get an upgrade on one segment even if none are available on the other.
