Two points:
1. Actually, isn't this theft of inventory? You are tying up a second seat that the carrier might have been able to sell.
2. Not all CSR's are dumbos. Had you presented to my counter, I would have most probably caught on to 'your scheme'... and as a result, pressed LOTS OF BUTTONS on the cash register.
What flight are you on again...???

I'm going to take it from the smilie that your post is one big joke. One of the nice things about flying full Y or higher is that the airlines actively encourage duplicate reservations to cover things like missed connections, early arrivals, etc.
